Flu epidemics and yearly flu patterns are always very similar. The number of infections and the severity of the infections increases during the winter months.
MORE SUN IN THE SUMMER
Medical scientists have noticed this pattern and were forced to come to the obvious conclusion: The one significant difference in human physiology between summer and winter is the obvious exposure to sunlight.
Sunlight is the primary source of vitamin D for human beings. Vitamin D is the controlling molecule for the immune system.
It stimulates the immune system to attack microorganisms, such as viruses, and it modulates the immune response so that it is not overactive.
Thus,when a person responds to a viral infection that person’s immune system does not attack the body itself.
OVER ACTIVE IMMUNE SYSTEM
It has been noted, that a hyper immune system is one of the causes of the many deaths that have been noted during flu epidemics.
This is why young people have a greater mortality and morbidity than older people. The immune system of the younger people is much stronger than that of the older people.
This can be a disadvantage if the immune system attacks its own body.
Most of the worlds population do not take vitamin D supplements. The average person relies on Sun exposure for their vitamin D requirements.
In the winter that exposure is significantly reduced and therefore so is the availability of vitamin D.
Whether the vitamin D hypothesis is true, remains to be determined. However, taking vitamin D supplements is not dangerous if your vitamin D level is not abnormally high.
This is very rarely the case.
One can attain a lab test to determine the vitamin D level; however, the average person very seldom has hyper-vitaminosis levels of vitamin D.
If you are afraid of taking vitamin D, but yet want the benefit of its protection you can simply expose yourself to sunlight and thereby increase your levels of vitamin D without fear of having too much vitamin D in your bloodstream.
Vitamin D is also extremely beneficial for other reasons, as we will soon see in another article.
