what sun does to the body
Long-term sunlight exposure is known to be associated with the development of skin cancer, skin aging, immune suppression, and eye diseases such as cataracts and macular degeneration. Short-term over-exposure is the cause of sunburn, snow blindness, and solar retinopathy.
Our body creates most of our vitamin D from direct sunlight on our skin. We also get vitamin D from some foods â including eggs, meat and oily fish such as salmon, mackerel and sardines.
