Sun Damage Questions & Answers
We are all vulnerable to the harmful effects of the sun. However, some people may be more at risk than others. People that have sustained burns are definitely in one of the top groups of individuals that are at higher risk. Below you will see a list of what else can put you in a high risk bracket.
What is Sun Damage?
Sun damage, also identified as photo damage, refers to how the sun alters the look and feel of the skin. Sun damage is a form of extrinsic aging, which is early aging that is caused by the surroundings. Extrinsic aging is collective, means that effects exacerbate with repeated, unprotected contact to the sun.
What Causes Sun Damage?
Sun damage is caused by frequent exposure to damaging ultraviolet (UV) rays. UV is an undetectable form of radiation emitted by the sun. There are two types of UV rays, UVA and UVB. UVA rays penetrate deep into the skin and are the major source of early aging and skin cancer. UVB rays primarily access the surface of the skin and are the key source of sunburns.
How Often Am I Exposed To Harmful UV Rays?
Whether you are walking to your car, driving to work, or simply sitting near a window, you are exposed to harmful UV rays. This type of daily contact is known as secondary UV exposure.
Secondary exposure occurs where you least expect it. It can occur in the shade, on cloudy days, even while you are indoors. It is likely that the usual individual is exposed to more than 10 hours of indoor UV rays every week. Add to that over 7 hours of outdoor UV rays a week and without a suitable shield, your weekly UV-radiation exposure might total nearly 20 hours. That’s like spending the weekend at the beach without wearing sunscreen.
