What are the risks of excessive sun exposure?
The most obvious danger of too much sun exposure is sunburn. Under a strong microscope, sunburned skin would show that the cells and blood vessels have been damaged. Sun damage causes the skin to become dry, wrinkled, discoloured and leathery. Although the skin appears thicker, it has actually been weakened and will bruise more easily as a result, says an expert of the best dermatology clinic in New Town, Salt Lake and Rajarhat.
However, the sun's most severe threat is that it is the leading cause of skin cancer, which is now the most common type of cancer. Most skin cancers, according to doctors, can be avoided by avoiding sun exposure.
How can I avoid the sun's harmful rays?
The best way to bypass sun damage is to stay out of the sun, but most of us go outside on a daily basis. So, when you go outside, always take the following precautions:
• Always use sunscreen. Every day, apply it to your skin. Make it a habit.
• Bypass exposure to the sun between 10 a.m. and 3 p.m. The ultraviolet rays that cause sunburn are at their peak during this time.
• Put on protective clothing when you do go outside, especially for extended periods during the day. Long sleeves and slacks and a wide-brimmed hat can help shield your skin from the sun's harmful rays, says the best dermatologists and doctors in Salt Lake and New Town.
What does SPF mean in sunscreen?
SPF is an abbreviation for sun protection factors. The SPF number indicates how well the product will protect you from UVB or the sun's burning rays. (Most sunscreens also absorb UVA or ultraviolet "A" rays.) The greater the amount of protection, the higher the SPF number. Everyone should use sunscreen with at least an SPF of 30. If you have a history of skin cancer or pre-cancer, you should use an even higher SPF sunscreen.
What is the best way to apply sunscreen?
When used correctly, sunscreens are extremely effective. To give yourself the best protection, follow these steps:
• Apply sunscreen 20 to 30 minutes before going outside.
• Reapply sunscreen every 2 hours while outside, even if the product says "all day." Reapply sunscreen more often if you sweat a lot.
• Apply sunscreen to all exposed areas, including your ears, lips, face and the backs of your hands.
• Rather than rubbing it in, smooth it on.
• If you wait until you get to the beach to use sunscreen, you may already be sweating and the moisture of sweat makes sunscreens less effective and difficult to apply, says the expert of the best dermatology clinic in New Town.
