Springtime brings warmer weather, which means more time in the sun! Excess sun without proper protection can cause all sorts of damage to your body, including cancer. Keep reading to see why experts suggest sunscreen with a sun protection factor (SPF) of at least 30.
What is SPF?
Many health problems can occur if one does not protect their skin from the sun’s harmful rays. SPF is a number that measures the degree of protection one receives from sunscreen, and experts agree your SPF needs to be at least 30. The sun produces two different types of damaging rays: UVA rays and UVB rays. Some sunscreens only protect against UVB rays, make sure you check for sunscreens labeled “broad spectrum,” to get full protection from both types of rays.
SPF reduces risk of skin cancer
Did you know skin cancer is the most common form of cancer in the United States? UVB rays affect the genetic material of the skin which can lead to skin cancer. When the skin’s pigment cells are damaged, freckles appear that can also lead to melanoma. By wearing sunscreen daily, one can decrease the chances of getting skin cancer. Sunscreen prevents radiation from reaching your skin.
SPF reduces early signs of aging
While UVB rays are most responsible for causing skin cancer, UVA rays cause premature signs of skin aging. These rays go deep into the skin and damage your skin’s elastic fibers. By wearing a broad-spectrum sunscreen daily, you are preventing the appearance of dark spots, wrinkles, and sagging skin.
It is important to wear sunscreen every day, not just when you are laying out by the pool. Even on a cloudy day or while you are inside, the sun’s harmful ultraviolet rays can still reach your skin. Around 80% of UV rays can move through the clouds and your windows. Slather on that 30 SPF every day!
