Getting more Sunlight is an ultimate source of vitamin D into the body that reduces the risk of respiratory illness like common cold or influenza, says a new study.


The study conducted by researchers at the Yale University claims that people who are more exposed to Sun never lack vitamin D and the chances are less to fall in respiratory ailments or influenza.


The research led by Dr. Sabetta was conducted on 198 healthy adults monitoring their vitamin D levels for about six months. The study found that 18 people with high level of vitamin D are developing less flu-like symptoms during winter season. Whereas the rest of the people are falling sick frequently having low level of Vitamin D.


The study concluded with a finding that the risk of allergy also reduced 50 percent having vitamin D level of 38. Thus, sunlight is the best source of getting Vitamin D into body, the study suggests.
