What is the difference between ultraviolet A and ultraviolet B rays?
UV rays can burn and harm your skin without ever causing you to become warm. Learn more about UVA and UVB radiation and how to protect yourself against them.
You’ll hear a lot about ultraviolet radiation if you want to stay safe in the sun. Because UV rays are the portion of sunlight that promotes skin cancer and ageing, they should be avoided.
UV radiation is also emitted by tanning beds. Tanning beds harm the skin in the same way as the sun does.
It’s important to understand how these rays work so you can protect yourself. Isn’t it true that you know who your adversary is?
What is UV radiation and how does it work?
Although it may appear strange, the sun does not release only one type
of light. The sun sends down a wide spectrum of light to us on Earth.
What is UVA (ultraviolet A) radiation?
UVA radiation accounts for nearly all of the UV rays that reach the Earth’s surface. UVA rays penetrate our skin deeply and can even travel through glass.
UVA causes skin damage, resulting in a tan. It is the main source of radiation in tanning beds. It is responsible for nearly all types of skin ageing, including wrinkles. UVA causes free radicals and destroys collagen and elastin in the skin.
And, according to new studies, it doesn’t stop there.
Saira George, M.D., a dermatologist at MD Anderson Cancer Center, believes UVA and UVB work together to produce more significant disorders including skin cancer.
What is UVB radiation?
Use a sunscreen with an SPF of 30 or higher if you must go out in the sun. Choose one that is water-resistant and provides broad-spectrum protection.
Sunscreens with a broad spectrum reflect and absorb UV rays. They guarantee that you are protected from both UVA and UVB rays. Apply sunscreen 30 minutes before to going out in the sun, and reapply after swimming or sweating.
Also, don’t underestimate the amount of protection that covering up can provide.
“Clothing can be more dependable,” George explains. “A sun protective clothing can assist you fill in the gaps left by sunscreen.”
