Sunburn & ultraviolet light

Sunburn dramatically dries and dehydrates the skin, causing premature ageing, cancer and in extreme cases can be fatal.

Ultraviolet light is a term used for the solar radiation that is in the range of wavelengths from 280 nanometres to 400 nanometres. UVA refers to radiation between 320nm and 400nm. UVB refers to radiation between 280nm and 320nm. Radiation below 280nm (UVC) is absorbed or scattered in the atmosphere and does not reach the earth.

Melanin is the protein produced by the body that gives skin it’s colour, while also offering some protection by scattering UV rays. UVA rays are responsible for the darkening of existing melanin, while UVB rays cause the body to produce more melanin.

While UVA rays will burn the skin, it is the UVB rays that are predominantly responsible for sunburn. UVB rays are also the main cause of skin cancer and the greatest skin damage is caused by rays around the 305 nanometre length.

A broad spectrum cream on exposed areas, hat, light clothing, hydration, sunglasses and staying out of the sun during the hottest parts of the day are all preventative measures to avoid sunburn. Have a safe summer, but still remember to get enough sunshine to keep up your Vitamin D levels.
