Environmental Triggers

The H1N1 outbreak occurred across areas where humidity varied from high to low. The H1N1 outbreak occurred across areas with widely varying temperatures. The article attributes about two-thirds of autoimmune disease contribution to environmental factors and one-third to genetics. Cloud cover was inconsistent in areas where the H1N1 outbreak peaked. Winter factors such as temperature and humidity are presented as less central than solar radiation for influenza protection in this analysis. Environmental inputs collectively are the primary driver of which genes are active in the body at any moment. Gene expression patterns shift across the lifespan as a result of age. Emotional and psychological states directly influence gene activity. Synthetic chemicals are said to contribute to autoimmunity by inducing leaky gut and by binding directly to tissue. Environmental factors unique to outdoor settings are proposed as a mechanism behind outdoor exercise's neurological advantages. Diet and gut permeability are presented as the highest-priority autoimmune trigger category because food is the most frequent external input. Pathogens are described as the second most common environmental autoim…
