Ultraviolet (UV) rays are a type of radiation energy produced by the sun and artificial sources like a solarium. The sun’s ultraviolet radiation is the main cause of skin cancer. UV rays can also cause sunburn, premature ageing, tanning and eye damage. Unlike the light and heat that emanates from the sun, our senses cannot detect UV rays. This means we don’t notice any damage until it has already been done.
The level of UV rays is dependent on a number of factors including the time of the day, time of the year, altitude, how close you are to the equator and how much cloud cover there is. The World Health Organisation has a Global Solar UV Index which measures UV ray levels from 0 to 11. Sun protection is recommended when levels are 3 or higher.
Overexposure to UV rays can have a number of negative health consequences including:
Our bodies manufacture vitamin D when the sun’s UV rays interact with 7-dehydrocholesterol (7-DHC) present in the skin, so some exposure to UV rays is acceptable. However, we can produce only a limited amount of vitamin D from UV radiation so overexposure is not a good. A few minutes at midday are sufficient for many people.
Most people know that protecting yourself from UV rays includes putting on sunscreen, clothing, a hat, sunglasses and staying in the shade. However, protecting yourself from UV rays that penetrate through windows in your home is also important. Roller sunscreen blinds are fantastic when you want to control heat and dangerous UV rays penetrating through windows without eliminating the view or the amount of light entering a room.
