What is UV:
Ultraviolet radiations are the invisible rays that are part of the energy that comes from the sun. These can burn the skin, and cause skin cancer. UVC is the most dangerous type of ultraviolet light but cannot penetrate earth’s protective ozone layer.
TYPES OF UV RADIATION:
The most common form of UV radiation is sunlight, which produces three main types of UV rays:
UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB.
Like all forms of light on the EM spectrum, UV radiation is classified by wavelength. Wavelength describes the distance between the peaks in a series of waves.
UVB rays have a short wavelength that reaches the outer layer of your skin (the epidermis)
UVA rays have a longer wavelength that can penetrate the middle layer of your skin (the dermis)
Both UVA and UVB rays can cause damage to your skin. Sunburn is a sign of short-term overexposure, while premature aging and skin cancer are side effects of prolonged UV exposure.
Certain oral and topical medicines, such as antibiotics, birth control pills, and benzoyl peroxide products, as well as some cosmetics, may increase skin and eye sensitivity to UV in all skin types. Check the label and ask your doctor for more information. [READ: Top 10 Best Sunscreens (SPF) Available in India for All Skin Types]
Sunlight is not the only source of UV radiation you may encounter. Other sources include:
Mercury vapor lighting (often found in stadiums and school gyms)
Some halogen, fluorescent, and incandescent lights
Some types of lasers
Benefits of UV
Exposure to UVB radiation helps the skin produce a type of vitamin D, (vitamin D3), which plays an important role – along with calcium – in bone and muscle health. However, the amount of UVB exposure needed to obtain a benefit depends on several factors, such as: the amount of vitamin D in your diet, skin color, sunscreen use, clothing, where you live (latitude and altitude), time of day, and time of year. Also, the FDA has not cleared or approved any indoor tanning device for producing Vitamin D and you can also get the benefit from the brown false eyelashes
UV radiation, in the form of lasers, lamps, or a combination of these devices and topical medications that increase UV sensitivity, are sometimes used to treat patients with certain diseases who have not responded to other methods of therapy. Also known as phototherapy, this method of UV exposure is performed by a trained healthcare professional under the supervision of a dermatologist.
