Why protect skin against sun
Sun, the source of Vitamin D, and unfortunately the cause for skin cancer too. Skin cancers are caused by damage from the sun’s ultraviolet (UV) rays. Protecting the skin from the sun can help prevent these cancers. Here is how and why you should protect your skin from the sun.
How does the sun damage the skin?
The UV rays from the sun penetrate deep into the skin and damage cells. These cells are then at risk of becoming cancerous. You can’t feel UV damaging your skin and it happens even when the sun doesn’t feel hot.
Getting sunburns causes the top layers of skin to release chemicals that make blood vessels swell and leak fluids. Skin turns red and feels hot and painful, and severe sunburn can lead to swelling and blisters.
Sunburn is dangerous at any age, but it’s especially harmful in children and young people. Sunburn in childhood can greatly increase your risk of developing skin cancer later in life.
After you’ve been sun-burnt, the skin peels to get rid of damaged cells. Eventually, it will heal and look healthy, but permanent damage may have been done. Although people with naturally dark skin are less likely to get skin cancer as darker skin has some protection against UV rays. However, skin cancer can still occur.
Sunlight also causes premature aging of the skin. 80% of visible skin aging is caused by sun exposure. The UV ray of the sun breaks down collagen and prevent synthesis of new collagen material. This makes the skin becomes loose, wrinkled, and leathery much earlier if left unprotected.
How to be safe in the sun?
Sun damage doesn’t just happen when you’re on holiday in Cox’s Bazar. It can happen when you’re not expecting it, for example when you go for a walk or just get out of your office to your car.
