Self-appointed economists drop drips of wisdom
It is good to see and read the hoo haa that is being raised over rapid deforestation in Free Sri Lanka. Sunday Punch in the Sunday Times of November 29 dealt this blow: “New writ opens season to slam the country’s rainforest canopy: 700,000 hectares of forest land condemned to face the axe before the altar of Mammon.” Punched well but will it have any effect? Will the new ordinance be changed? Will racketeers and shitty money makers stop felling trees, even if it’s forbidden by law? Most think only of immediate personal gain and to hell with the country and its welfare, fauna and flora included!
A recent The Island editorial described an ugly incident in Polonnruwa, where the State Minister of Wildlife Protection and Forest Resource Development, Wimalaweera Dissanayake, “had conniptions, when Wildlife Officers refused to follow his order that villagers be allowed to graze their cattle inside wildlife sanctuaries What he was doing was to violate the Fauna and Flora Protection Ordinance.” Can you see the tragic irony of the situation? Here the State Minister is going against his TORS and mandate. Not only does this sentence show how corrupt things have become normal, but also taught readers a new word: conniptions. Cass had to google fast to get its meaning, which is “a fit of hysterical excitement or anger.” How very apt! We are justified in mixing in a pinch of insanity caused by temporary power and of course self interest into the aforesaid incident. Female forest officer Devani Jayathilake should be greeted with hosannas all over again. She boldly argued with State Minister Sanath Nishantha to save a mangrove earmarked for an ostensible playground but thought to have a hotel built. We saw how that State Minister ranted at the woman, in dire conniption! His power was being challenged while his devious plans were exposed. Many men just stood around, Cass remembers, as Devani stood her ground for country – alone and unaided.
Pseudo economists Sunday Punch
on 29 November also dealt a strong punch with the sub heading “Wimal’s 5000 buck shot”. The article read thus: “Perhaps Weerasangilige Wimal Weerawansa was born with the proverbial silver spoon stuffed in his oral cavity right down to…” Yes, one could think thus observing the luxury he ensconces himself and his family in, sunk in further luxury as he drives around, oops sorry – as he is escorted around in his government luxury vehicle costing millions. May be what we heard him say about not having 25 rupees to join a school field trip to Sigiriya was in a previous birth.
Now he is turned pro-government economist pronouncing the Rs 5000 handout to the poorest of the daily employed should suffice for an entire month for his/her family! Won’t last a single man for basic living for even a week; with prices what they are.
He is following in the older footsteps of economist pundit, earlier tuition master, who made a similar statement. They sound as if these blighted disadvantaged are lice or mice!
Of course, Cassandra must add that people on the whole are never satisfied and demand bigger handouts whenever there is even a whiff of economically straightened circumstances. It’s always asking for more and in such an ugly fashion with insults hurled at the government. If the men folk stopped imbibing or drug taking and a bit of savings was done, they could try at least to weather difficult times instead of expecting full manna to fall to them as if it is fully deserved.
Demeaning TV clips
Cass is certain others join her when she opines that TV cameras should not, or very briefly shoot scenes where women go to town howling, crying, clawing and hurling insults. When the unemployed locked-down are shown on TV and after the Mahara prison riot these scenes were focused on woman tearing their hair, screaming and sobbing and even fainting with sheer sorrow. At what? Their rioting kinsman and women prisoners. If only they had restrained them and showed such concern when they were peddling drugs or actually abusing it.
More restraint is called for. Our people will not contain their exuberant emotions, mostly of sadness or revenge and hate, and hardly ever behave with dignity and the calmness all religions advocate. Cameras should not focus on such.
Judging execution of duties depends entirely on political party in power
Headline in a Sunday newspaper of November 29 read thus: “HRCSL concerned over health and threats to Shani’s life”. Shani Abeysekara, ex-CID Director, is the person imprisoned and now in danger of his life having contracted Covid-19. His crime and reason for his arrest and incarceration are having done his duty diligently during his tenure of service. What we see now is that good duty served gets classified as crimes when governments change with different parties grabbing the reins of government. What was a crime then is not so now and the diligent, dutiful and hard-working official is termed a criminal when new leaders come marching in. Efficient public servants of then deserve punishment. Mistakes, misappropriation of funds then is pardoned and blameless now. And so the roller coaster moves with changes of government. And who ultimately suffers: WE the PEOPLE. We will have no police or judges or anyone to rely on. The stealer of a coconut then, will continue to be the stealer now and he of course gets more than his due punishment since he carries not a smithereen of clout. He is expendable. Hence our quandary: battered on one front by Covid; on another by economic and financial deprivation; and a third front buffeted by fractured faith in government and its long arms.
Cass sadly supposes this beautiful land of ours will never see a Nelson Mandela at the helm of government. Also, never an admittance of a fault or mistake by big bugs in power.
An unexpected flash of sunshine
Cass watched the BBC 1000 Women in their series Witness History on Tuesday December 01 feeling doom, gloom and despair. All driven away by the shy smile of Mrs Sirimavo Bandaranaike featured beautifully as the world’s first woman Prime Minister. As her daughter Sunethra narrated, she rose to the elevated job very soon and held her own with dignity and sureness amongst world leaders. Those were the politicians my friend! Maybe many of them were good not being born, bred, trained and tainted as poli-tikkas. They all had their warts, big and small, but in the long run we could be proud of them, and they did serve the country and its people. To when? JRJ? Mould seems to have been broken by the bludgeon of self interest, and monetary and power gain. We had faith of a resurrection with the election of the present Prez.
With a woman at the helm of the health ministry it had to be a man – Leader of Opp – who proposed that hygienic needs of women be tax free. Scotland gives all products free having passed that in their Parliament. Our minister is too busy with the mumbo jumbo of the esoteric.
Oh, deari deari me! Such a pity Biden’s playing with his dog caused him to take a toss and suffer a hairline fracture, necessitating the wearing of orthopedic boots for a while. Anyways, thank heavens it was only a minor accident. Cass of course, given to cursing and the evil tongue, is sure it was es and kata vaha, meaning the evil eye and tongue that brought on the mishap. Inevitable when a good man succeeds. Sure, Trump would have swung his golf club the harder with delight
Can castor bean,rubber and tea seeds solve Sri Lanka’s diesel deficit?
by Chandre Dharmawardana
According to the “Dilbert Principle“, we rarely recognise our own idiocies, yet we can clearly identify the idiocies of others. Everyone from the Aragalaya man to the “Aemathi Thumaa” has faulted others for the current crisis. And yet, although ordinary citizens can act to resolve the crisis, a culture of confrontation, nurtured by revolutionary ideologies, coupled with unrealistic demands for various “rights” or the resuscitation of ancient myths, has become second nature to Sri Lankans. The government has ground to a halt, and action via citizen groups is essential to deal with the crisis in food and fuel.
In my article in The Island commenting on Mr. Dhammika Perera’s plan to race forex (The Island 13-June-2022), I briefly stated that “Castor is a fast-growing ‘weed’ that is not attacked by pests or livestock. It can be grown among coconut trees or on infertile lands. Its seeds yield a clear oil, directly usable in most diesel engines”. I received many queries on how diesel fuel may be replaced by cheap local oils.
Diesel fuel and electricity are the main energy sources, more important than petrol, that drive the modern world. Wealthy countries produce diesel and maintain reserve stocks as a part of their national security. However, small countries are abjectly dependent on powerful countries that wage war for fossil fuels and control them.
Rudolf Diesel was a 19th century scientist-inventor, influenced by Sadi Carnot’s work in France, that led to the second law of thermodynamics. Diesel was strongly social conscious and moved to help small entrepreneurs, trampled down by wealthy conglomerates who alone controlled the giant steam engines of industry, trains and ships of the late 19th century. In 1892-1895 Diesel patented a compression-ignition engine that ran entirely on vegetable oil, ideally suited for small-farm applications using farm-produced oil. Dashing Diesel’s socialist objectives, his engine became a tool of the Western industrial and military enterprise. By the 1920s, the inexpensive distillate from petroleum crude became the main fuel for Diesel engines, replacing vegetable oil. It is this distillate that is today called “diesel fuel”.
Today, people express surprise that diesel engines may use vegetable oils, since modern engines have been adapted for the distillate from petroleum crude. We describe below how vegetable oils can be used to overcome the fuel crisis, with little or no modification of the engines.
Although coconut oil, peanut oil, etc., can be used, they are very expensive, compared to non-edible waste cooking oil, waste animal fats, castor oil, rubber or tea seed oil, or oils from Madhuka (Sinhalese mee thel) and Neem. Biodiesel is a chemically modified form of vegetable oil, compatible with diesel engines. Our interest is in directly using vegetable oils WITHOUT converting them to standard biodiesel by chemical processing. However, in the following we discus both bio-diesel and use of untransformed vegetable oils.
The 2020 world market prices of natural gas, gasoline, diesel and bio-diesel were US$ 2.18, 2.18, 2.4, and 3.33 per gallon respectively. The current prices change rapidly, but the international price of bio-diesel is irrelevant when the fuel is made locally, without forex. Untransformed vegetable oils, produced in the farm, is an unbeatable option when used for running farm machinery and generating electricity.
Lankan scientists and engineers have argued, even before independence, that unlike many countries, Sri Lanka has unique attributes to achieve self-sufficiency in food and energy, due to its rainfall, reservoirs and biodiversity. In the 1970s some of us had undertaken a study of what was then called “alternative technologies”, and the concepts evolved were presented in a BBC movie. That, too, was a time of food and forex shortages under the Sirimavo government. Today, Sri Lanka is in more dire straits. Hence a return to basic “alternative technologies” achievable within the naturally available resources of the country, is needed, irrespective of the availability of more loans and moans from the IMF.
Direct use of vegetable oils as diesel fuel.
Oil from castor seed (up to 3 tonnes/ha of which nearly 50% is oil) is a good fit to meet Sri Lanka’s urgent needs. It grows easily and rapidly on infertile soil, with few pests or enemies. Similarly, rubber seed (up to 2 tonnes/ha) and tea seed (3-4 tonnes/ha) are mostly left discarded. The main difficulty in using castor or other vegetable oils in modern diesel engine is their high viscosity. Castor oil is some 75 times more viscous than diesel fuel at 400C. Tea-seed oil and rubber-seed oil are better, being only 9-12 times more viscous. We found in our experiments that castor oil, at suitably high temperatures, achieved a viscosity matching diesel.
However, the use of elevated temperatures (above the boiling point of water) raises serious safety and insurance issues, and the method is more suited for stationary diesel engines. Stationary engines can generate electricity and charge batteries that power electric cars and farm equipment. The viscosity of the oils from rubber and tea seed, depending on quality, may be lowered to the viscosity of diesel fuel at easily accessible temperatures. Thus, the hot coolant water (radiator fluid) of the diesel engine could be re-circulated to heat the rubber-seed oil for direct use in a diesel engine. However, more research is needed to implement the hot-fluid system for which only preliminary studies are available.
A simple approach for the direct use of vegetable oils in diesel engines is to dilute the vegetable oil with compatible solvents, like ethyl acetate, that can be produced locally using alcohol and acetic acid, both being products of fermentation of biomass. Considerable work has been done in Brazil and Spain in developing such approaches, using dissolved-vegetable oils.
Indirect use of vegetable oils by converting to biodiesel by trans-esterification.
The commercialized method for using vegetable oils is to convert them to bio-diesel using “esterification”. Here the vegetable oil is treated with a substance, like sodium hydroxide and methyl alcohol (wood alcohol) or ethyl alcohol (spirits of wine), when a layer of glycerol settles to the bottom, and a lighter liquid separates to the top. The top layer is the desired “bio-diesel”. This “trans-esterification” process is highly optimized in industrial production to get optimal yields and reduced costs. However, do-it-yourself conversions of waste cooking oil to bio-diesel is a win-win situation in providing the otherwise unavailable diesel fuel to forex-poor consumers.
A “recipe” for converting castor oil or waste cooking oil (e.g., from cooking oils, like sunflower oil) can be developed using known chemical data for the fatty acids in these oils. We illustrate the method for one litre of waste cooking, giving the rough amounts of ingredients needed, noting that trial and error adjustments are needed for different waste oils.
1. One litre of moisture-free waste cooking oil, filtered to remove frying residues.
2. 3.5-4.0 g sodium hydroxide (not more than 0.1 moles). This is a corrosive substance that should be kept dry.
3. 200 ml (about 4.5 moles) of dry methyl alcohol (wood alcohol) or ethyl alcohol (~ 4.5 moles).
4. Blend (at low speed) the methyl alcohol and the sodium hydroxide until completely dissolution, to be used immediately as it absorbs moisture from the air.
5. Add the filtered cooking oil and blend at low speed for about 1/2 hour. Reaction is facilitated if the blending vessel is kept warm.
6. Let stand until the liquid separates into two layers.
7. The top layer is the bio-diesel, and the bottom layer (glycerol) is drained out.
This is a simple procedure that a cooperative of restaurants or households in a neighbourhood can use to convert their waste cooking oil into diesel fuel. This oil can also be used to fuel an oil-burning cooker or stove instead of using LNG, soot-generating charcoal or wood for cooking.
The biodiesel can be used directly (or mixed with petroleum diesel) as fuel in a standard diesel engine. If the untreated vegetable oil were used (either by using the heated oil, in an engine equipped to heat the input oil held in an auxiliary fuel tank, or by blending with a solvent like ethyl acetate), then (a) the expense for sodium hydroxide and methyl alcohol can be avoided, (b) even the glycerol gets used as a fuel and so the full energy content of the vegetable oil is used in the diesel engine. Otherwise almost half the energy content is lost as waste glycerol. Furthermore, since glycerol is an oxygen-rich chemical, it promotes a cleaner burn in the engine; the exhaust gases contain less soot and less noxious oxides.
Undoubtedly, many owners of high-end diesel cars will hesitate to use artisanal bio-fuels in their cars unless rigorous quality controls are imposed. Private companies, estates, and small entrepreneurs should lead in producing and using bio-diesel or vegetable oils, in diesel engines, without waiting for government action.
Fishing without gas-guzzling
Towards fuel-efficient fishing for food and nutritional security
by Prof. Oscar Amarasinghe
Chancellor / Ocean University of Sri Lanka
President / Sri Lanka Forum or Small-Scale Fisheries (SLFSSF)
The present economic crisis, and the associated energy crisis, has mightily affected the fisheries sector, reducing the number of boats at sea, dwindling market supply, soaring fish prices, all affecting food and nutritional security of the people in Sri Lanka. Being a highly fuel-dependent sector, there is a pressing need for the sector to find means of economising on fuel and continue to provide the most important animal protein to the people-the Fish. Yet, the tale of woe of fishers is that they have neither the physical nor economic access to fuel. Time has come to reexamine ways and means of improving the fuel use efficiency of fishing vessels to meet the escalating food crisis which has already hit the people with a monstrous force.
Fishing is among the most energy-intensive food production methods globally, and the world’s fishing fleet consumes about 1.2% of the total global fuel consumption, which is equal to 0.67 liters of fuel for each Kg of live fish and shellfish landed. In dealing with the issue of fuel efficiency in fisheries, it is imperative to understand how energy is expended in a fishing vessel and what means are available to minimize energy use without any fall in the efficiency of productive operations and incomes. It may also be necessary to understand how energy use can be influenced by the operator, boat-builder or mechanic, etc. Apart from improving the fuel use efficiency, various parties have been trying out the potential for using alternative sources of energy such as solar energy and wind energy. Yet, information on various issues related to the use of solar energy, use of sail on motorised fishing boats, the diverse benefits and costs associated with such innovations, etc., are quite scanty.
Giving due consideration to the significance and urgency of the above issues, the SLFSSF (Sri Lanka Forum for Small Scale Fisheries) organized an Interactive Platform on “Improving the energy use efficiency in fisheries” on the 17th of June. This platform brought together representatives of the Department of Fisheries, Boat yards, companies producing solar power, marine engineers (consultants), civil society organisations, fishing leaders, academics and researchers of the SLFSSF, etc., who deliberated on their knowledge and experience on various aspects of energy use in fishing crafts and proposed certain recommendations by common consent. The aim of this article is to bring to the attention of the fisheries authoritie, and other relevant parties, the results of these deliberations, which have very important implications for immediate, short term and medium-term measures that could be adopted to improve the fuel use efficiency in fishing vessels.
It was disclosed that only about a third of the energy generated in a fishing vessel is expended to turn the propeller, while the rest is used to overcome resistance offered by a diversity of factors: 27 percent to overcome wave resistance; 18 percent to overcome skin friction; 17 percent to overcome resistance from the wake and propeller wash against the hull; and three percent to overcome air resistance. This information has already been published by the FAO more than 20 years ago, although they have evaded the attention of fisheries authorities in this country. In overcoming resistance offered by waves, hull fouling, wake and propeller wash, etc. ,a number of strategies were proposed to be adopted, which included, slowing down (reduced speeds), proper hull designs, regular engine and hull maintenance, capacity building of operators, etc.
Speed was one factor which was discussed in detail. Generally, fishers like high speeds and try to reach fishing grounds within the shortest time possible which will allow them to return with the catch early. Thus engines are often run to maximum speeds. It was revealed during deliberations that fuel requirement for increase in speed increases exponentially. To double the speed, one needs more than double the amount of fuel. Thus a reduction of the speed appears to be an effective means of increasing fuel use efficiency. It has been estimated that 10-20 reduction in the speed could result in 35-61 percent savings on fuel. The FAO has published optimum speed recommendations for fishing vessels by the size of the vessel, and they were accepted as applicable to fishing vessels used in the country at present. For example, for boats with a waterline length of 13 meters, the recommended speeds are 8.5 and 7.1, knots, respectively for long thin vessels and short fat vessels. The same for boats with a 15 m water line are 9.1 and 7.7 knots, respectively. Of course, reduced speeds will result in longer fishing trips, short periods of shore leave and/or lesser number of trips annually. The use of fish finding devices, information from NARA to locate fish resources and reach fishing grounds early, etc., are important strategies to surmount loss of fishing time and to reduce the amount of fuel required to travel one nautical mile. Fuel wastage could also be minimized by reducing the number of zero catch days which is quite common in fisheries, often emerging from resource and weather uncertainties. In this regard, too, information on fishing grounds and weather would be of great value. Such information show where and what opportunities exist to improve energy use efficiency.
Another short term measure would be to minimize energy expended to cope with hull fouling. There is accumulation of marine growth on the boat hull, resulting in reduced speed. It was revealed that about 18 – 20 percent of the energy is expended to counteract hull fouling. The most appropriate measure to reduce resistance offered by hull fouling is to clean the hull below the water line during servicing, at regular intervals. It was also noted that by using a good anti-foul paint, which could last three year or longer, would be beneficial, economically, even if the investment cost could be high.
A complain that is often heard is that there is too much of fishing pressure in Sri Lanka’s waters, especially in inshore waters: too many crafts and too many fishers. In such a context, the higher the fishing pressure, the higher would be the fuel consumption and degradation of resources, and the lesser would be the income per fisher. Therefore, there is an urgent need to stop building small crafts such as fiber glass boats with outboard engine. One way to do this is to put an end to the process of registration of such crafts.
Recognising the fact that search for resource areas is a huge cost, needing the multiday boat crews to carry 12-14,000 liters of diesel on board, improvement of fish finding information, provided by the National Aquatic Resources Research and Development Agency, by strengthening the relevant process, would be of utmost importance in reducing search costs. Moreover, low-cost fish detection systems available in the world, could be tried out locally to find out their applicability and adoptability. If this is found to be successful, fuel savings from this measure would be colossal.
Quite often, due to the high cost of cleaning boat hulls below water line, boat owners ignore anti-fouling measures. Facilities for treating hull fouling, such as cranes and hoists, could be installed at harbours and they can be offered to fishers at concessionary rates.
Another short term measure could be the training and capacity building of boat crew on fuel efficient fishing and maintenance of engine and hull. The Department of Fisheries could organise awareness building workshops for boat owners and crews, with the participation of other experts, on the subject of energy use efficiency in boats. It was also stated that potential fuel savings gained from running at recommended speeds (reduced speeds) could be worked out and shown to the fishers.
Use of wind energy to charge batteries was also discussed. It was shown that this technology is already in use in some multiday boats, revealing the potential of adopting this technology with suitable modifications. Thus, installation of devices that use wind energy was recommended, which was also shown to be a good safety measure against the risk of engine failure which will make the GPS non-functional.
Medium and long term measures
An array of medium term measures were proposed, which included, solar panels for boats, sail assisted propulsion, engine and hull maintenance and two-day fishing trips for fiber glass boats with outboard motor.
The potential for using solar panels on fishing boats was discussed in detail. Experts, on the production and installation of solar panel systems, showed that the area required to provide a fishing boat with the requisite energy was too large, compared to the surface available for solar panel installation on boats. This was true for both small and large fishing boats in use. Moreover, the decks of multiday boats are tightly packed with extra fuel barrels, fishing gear, various sticks and poles and space is hardly available to accommodate installation of solar panels. However, there might exist some possibility of using a hybrid system (solar + fuel) in boats, but this needs to be researched.
Sail- assisted propulsion could also be a possibility. Of course, the use of sail as auxiliary propulsion, could result in very large fuel savings (up to 80 percent with small vessels on longer journeys) but the applicability of sail to motorized fishing is, however by no means universally popular. Sri Lanka too does not possess much experience in using sail-assisted propulsion in motor boats, although there is some scanty evidence of using such hybrid systems. Undoubtedly, sails fixed on motorised crafts, with inboard or outboard motor, are likely to tamper with fishing operations on the deck, while requiring additional ballast for balancing of the crafts. This warrants further research on this technology. Very specific circumstances are required for this to be a viable technology, for motorised fishing crafts in the country, in terms of weather conditions, the design of the fishing vessel as well as crew attitude and knowledge. Sailing puts additional requirements on the vessel, with respect to stability and deck layout, and sails are usually only a viable technology for use on vessels that have been specifically designed for sailing. Smaller fishing vessels may require the addition of further ballast or an external ballast keel (a weighted horizontal keel under the hull) to improve both stability and sailing performance across or towards the wind. What possibility exists in fixing sails on small FRP boats or offshore crafts is not known.
The deliberations further focused on the possibility of expanding the size and operating distance of the fleet of small fiberglass boats with outboard motors, which account for 40 percent of the fishing fleet or 24,000 crafts, operating up to a maximum distance of 24 nautical miles (up to the edge of the contiguous zone), engaged in one-day fishing trips. Following requests often made by small scale fishers and the need to improve the fuel use efficiency of fishing crafts, the possibility of modifying this craft by introducing a fish hold for icing of the catch and providing moderate accommodation facilities for crew, to allow for a two-day fishing trip was also discussed. The boat yards recognized the existence of this possibility but were of the view that further research on boat designs, and applicability and adoptability of this technology was required with the participation of technical and fisheries experts and fishing communities.
At a previous meeting on a similar subject, fuel inefficiencies arising from having about 5,000 multiday crafts with individual ownership was also noted. It was disclosed that such an organizational structure could change over to a cluster-based fleet, each cluster having its ‘mother ship’ to fish while the remaining boats could transfer the catch to the shore, minimising fuel costs to a great extent.
Expert panels and research
One of the momentous turns at deliberations was the emphasis laid on the need for an assemblage of technical experts, including engineers from boat yards, scientists (academics, researchers, consultants) fisher leaders, etc,. to guide technological change. This was especially important to design small boats with facilities to engage in two-day fishing trips, use of solar panels to assist using hybrid type of energy systems, sail assisted propulsion, use of wind power to charge batteries, etc. It was recognised that, endowed with a large array of educated and qualified experts, technicians, etc., what is required is for the Department of Fisheries to take the initiative in organizing such platforms and use them gainfully towards achieving the above goals.
Paradigm shift towards change
It is a pity that, endowed with a large conglomerate of intelligentsia and an array of experts in a large diversity of technical disciplines, the fisheries authorities still appear to work, confining themselves to their own little shells. Even with hesitation, it needs to be reminded that, by joining hand with others you will know what you know and what you don’t know, which is considered the true knowledge. It is said that, knowledge is power and knowledge shared is power squared. Therefore, it is strongly advised that the Department of Fisheries forms a Technical Expert Team, consisting of experts on marine engineering, boat design (architecture) and construction, solar power producing and system installation, sail assisted propulsion, and also of fishing leaders and boat owners, all of whom could guide them in boat designs and construction, fuel usage, minimizing energy requirements, search for alternative energy sources, etc.
As the theoretical physicist, David Bohm stated, it is the ability to perceive and think differently that will take us a long way rather than the knowledge gained.
Mental Healing the Yoga way
SNS:More than two years in Covid 19 pandemic the world has had cascading impact not only on the way we live but also on the mental health. These mental health and emotional issues have been among the foremost public health concerns throughout the world because of the pandemic.
World Health Organisation has been cautioning the world about the long term and short-term impact of covid 19 on mental health due to fear of infection or fear of death.Many recent government data have come out about the clinical impact of covid 19 on mental health. While the doctors have been working on the ways to minimise this impact experts are pushing for adopting Yoga’ practices in daily lives to ward off the mental health issues with the prolonged pandemic situation.
Anxiety, fear, depressive symptoms, sense of loneliness, sleep disturbances, anger etc. have been most prevalent situations during the pandemic times. According to The National Centre for Biotechnology Information Journal during COVID 19 relapse rates of all pre-existing mental health problems were seen to have increased. Quarantine has been another stressful situation which increases psychiatric morbidity through many different pathways.
How Yoga helps dealing Mental issues
Recent evidence, according to the NCBIJ, has shown promising results of yoga in various psychiatric disorders. Since Yoga is an inception of mind, body and soul. It has been significantly proven that Yoga can be significantly helpful in mental health disorders. Research shows Yoga has a positive impact on mental health such as improvement in coping and self-compassion and reduction of stress, anxiety, depression, and obsessions.
Research published in the Journal suggested yoga is being increasingly used in psychiatric disorders.According to experts, Yoga directly affects one’s mental health. Some breathing exercises ease stress, anxiety, emotions of loneliness, and sadness, while meditation and yoga therapy improve attention and confidence.
It can help us gain control of our emotions and become more aware of them. Additionally, yoga therapy and physical activity release dopamine and endorphins, two positive brain chemicals. These molecules, in turn, assist us in balancing our moods and combating common mental health conditions such as depression, anxiety, mood disorders, and others.
Yoga and regular physical activity are said to improve body awareness, reduce stress, ease muscle tension, strain, and inflammation, improve focus and attention, and calm the nervous system. Yoga also lessens the symptoms of OCD (obsessive-compulsive disorder), depression, and anxiety, among many other mental health disorders.Yoga is made up of several different elements, each of which is used in a different way, such as the chanting of “om,” deep breathing, yoga positions, and exercises. For instance, while chanting “om,” certain brain regions known as limbic system grey matter that are connected to an increase in inner turmoil become quiet. Accordingly, the capacity of the brain to cause emotional turbulence tends to decline.
