What is UV
Ultraviolet (UV) radiation is part of the electromagnetic spectrum emitted by the sun and in solariums. Whereas UV is essential for the production of vitamin D in people, yet uncontrolled exposure may result in acute and chronic health effects on the skin, eye and immune system. UV radiation is the major cause of sunburn, premature ageing, eye and skin damage leading to skin cancer. It is important to control UV exposure to minimise the risk of skin cancer and yet get some exposure for vitamin D generation in the body.
The World Health Organization’s Global Solar UV Index measures levels of UV radiation on a scale from 0 (Low) to 11+ (Extreme). It is recommended to take the sun protection measures when UV Index is more than 3.
