Research Studies

Asthma Research:

 Sunny hours have a protective effect on the risk  of asthma in schoolchildren; the more time in the sunlight, the less the risk of asthma. 

 http://www.ncbi.nlm.nih.gov/pubmed/20803035

Low sunlight exposure may be the reason for the worldwide epidemic of asthma.

 Bowel and Digestive Research:

 Low sunlight exposure correlates to high risk of Crohn’s disease.

Cancer Research:

Summer sunlight exposure correlates to a reduced risk of breast cancer among women of any age.  Canadian women who spent more than 21 hours per week outdoors had an average risk reduction of 29% compared to those who spent less than 6 hours per week outdoors, and those in the age group 60-74 had a risk reduction of 50%.

Girls with the greatest exposure to sunlight during the ages of 10-19 had a 35% decreased risk of breast cancer as adults .

Women who live in the sunniest areas and have the highest exposure to sunlight have a 65% reduction in breast cancer risk compared to those who have the least sunlight exposure.

Exposure to sunlight and tanning beds correlates to a substantial reduction in the risk of endometrial cancer.

People who receive more than 5 hours of sunlight exposure on the weekends have a reduced risk of melanoma of 33% compared to those who receive less than 4 hours per day.

Diabetes Research:

 Active sun exposure habits are correlated to a lower   risk of type-2 diabetes in women.

Heart and Vascular Disease Research:

  Active sunlight exposure habits correlate to a lower risk of venous clotting in women.

Immune Rystem Research:

 Sunlight exposure may improve the immune system with mechanisms other than the effects of  vitamin D production.

http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2036.2011.04601.x/abstract;jsessionid=8C0FB2047084564C49F184EFDF5B03D7.d03t03

 

Multiple Sclerosis (MS) Research:

 Low sunlight exposure, combined with the effects of a the Epstein Barr virus, may increase the risk of MS.

 http://www.ncbi.nlm.nih.gov/pubmed/21502600

Ultraviolet radiation (also found in sunlight) suppresses experimental MS independent of vitamin D production.

Osteoporosis research:

 Women in Spain who actively seek sunlight exposure have a reduced risk of  fractures of 91%! 

http://www.ncbi.nlm.nih.gov/pubmed/18221637

  High sunlight exposure correlates to 77% reductiion in  the risk of hip fractures in Alzheimer’s, stroke and  Parkinson’s patients.

http://www.ncbi.nlm.nih.gov/pubmed/21682695   

Sunlight exposure for one year leads to increased vitamin D levels, increased bone mass and a  73% reduction in the risk of hip fractures among Parkinson’s patients.

Vision Research:

Several studies show that the greater the amount of outdoor activity in natural light, the less the risk of Myopia.
