Is an increase in sunshine the reason for the reduction in deaths from Covid 19?
Experts from the University of Edinburgh, UK, compared the death toll from Cove 19 in 2474 US counties from January to April 2020 and the amount of ultraviolet A (UVA) in those areas at the same time.
It should be noted that “UVA” is the type of ultraviolet rays that are most common in sunlight. That is, the higher the intensity of the sun, the higher the amount of UVA in it. Similarly, prolonged exposure to the sun results in more UVA.
Clouds reduce the amount of UVA that reaches the ground as well as the sun.
The study found that counties with high sun / UVA had significantly lower mortality rates than those with low sun / UVA.
Two other similar investigations in Britain and Italy found similar results.
Scientists have also discovered that the reduction in deaths from corona due to sun exposure has nothing to do with “vitamin D”, which is formed in the human body due to sun exposure.
Based on the data, experts have calculated that an increase of 100 kJ per square meter in the intensity of the sun also reduces the number of deaths from covid by about one-third.
