Safe Tanning And the Definition of
UV Rays and UV Radiation
UV radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. There are 3 different types of UV radiation; UVA, B and C. UVC is the strongest wavelength but is also the shortest and usually gets absorbed by the ozone layer before it reaches the earth. UVB is responsible for most burns. UVA (UVAI and UVAII) is the least intense, but the most deeply penetrating. UVA and UVB can causepremature skin aging, eye damage (i.e. cataracts) and skin cancer.
95% of all UV rays are UVA, though less intense than UVB rays they are 30-50 times more common. UVB rays intensity varies by season, location and time of day. They are strongest between 10 am and 4 pm from April through October in the US. But they can burn you all year round especially around snow and ice since 80% of rays are bounced back at you and you are hit twice by them. UVA rays are relatively constant all day, every day and can penetrate through clouds and glass. Yes, there are UV rays on rainy, cloudy days even though you can’t see them. Wear your sunscreen!!
Even though UV radiation gives us an awesome tan, UV radiation damages the skin’s cellular DNA and can produce genetic mutations leading to skin cancer. Our tan is the body trying to protect itself from more DNA damage, whether from direct sunlight or tanning beds. As Dr. Dima says ‘The tanning bed bulbs emit UVA radiation which is less likely to burn you than UVB radiation. An easy way to remember this is UVA: ‘U will get VERY AGED skin’ and UVB: ‘U will get VERY BURNED.’
Bottom line though is that they both cause wrinkles and skin cancer.’ You can protect yourself from the damaging UV rays in many ways:
