Vitamin D to increase immunity to COVID-19
Among the many things to be done to avoid COVID 19 is to boost the immunity. Vitamin D is considered to increase the immunity to virus diseases. Exposing to direct sunlight for 30 to 45 minutes between 9.30 a.m and mid-day would generate an adequate amount of vitamin D to boost immunity. Several publications on Vitamin D and immunity are in a number of websites.
