Environment

How does Environment Affect Us?
Toxins in the air, water, and foods can have a direct effect on specific organs and cells. Chemicals such as tar, toluene, benzene and others can directly alter our genetic code, our DNA, and influence cells to become cancerous or to die. 

Psychological stress that is so prevalent in our fast-paced lifestyles influences our bodies to produce more of some hormones and less of others. In the short term, these stress hormones, such as adrenaline, help us to react to stress. In the long term, however, they can suppress the ability for our immune systems to defend against infection and other threats. 

Environmental hazards such as cigarette smoke and excessive sun exposure interact with our cells to create reactive molecules called "free radicals". Free radicals can be beneficial in helping break down waste products and dead cells in the body. However, when healthy cells are around these free radicals they can't defend themselves, and so they too, will also be broken down and destroyed. In the eye, cataracts, macular degeneration and some forms of glaucoma may be influenced by excessive exposure to free radicals. 

A lifestyle that proves beneficial for your overall health will have a positive influence on your eyes and your vision.
