Understanding Sun Damage
- Tips for Sun Protection
We love sun, don’t we?? It makes us feel good, positive. Plus it makes our bones healthier as it is stimulates vitamin D production in the body. Summers, when the sun bestow upon us its full wealth, is the time for picnics, beaches, trips, and also, ‘sunburns’.
How does sun damages our skin ?
Sun emits dangerous ultraviolet rays UVA and UVB, which penetrate into our skin, and harm them. UVA make up for the majority of the damage done and, irrespective of the season, they are continuously present in the sun rays. They penetrate deeper layers of the skin and can cause severe damage. Even in the winters and rains when you think you can roam about freely without any protection, these invisible devils are present. UVB mostly causes superficial damage, and they are emitted mostly during the summers.
