    Understanding the UV-Index

As the spring sun arrives...
Understanding the UV-Index

With spring here we will soon be spending more time outdoors as conditions brighten. But with sunnier days comes increased ultraviolet (UV) radiation.

UV radiation is a type of energy produced by the sun ray's and is the main cause of skin cancer.

Even on a cloudy day, UV levels can be high with UV able to be reflected and scattered in the clouds.

There are three types of UV rays: UVA, UVB, and UVC. UVC is the most dangerous form of UV radiation, but luckily this is absorbed by the atmosphere before it reaches Earth.

UVB penetrates the top layer of the skin and leads to sunburn.

UVA is the most potent source which we are exposed to all year long. UVA can even pass through windows and clouds and penetrates deep into our skin leading to ageing and increases our risk of skin cancer.

Because of the dangers associated with increased levels of UV, particularly in the spring and summer months when UV radiation is at its strongest, the UV Index was created.

The higher the UV Index, the stronger the strength of the UV and faster skin will burn.

Across the UK and Ireland, UV levels tend to reach 7 on the UV Index on the hottest days. At this level there is a risk of burning within 30-60 minutes.

As we spend more time outside, be sure to check the UV Index level near you through the local forecast!
