Question:How can we reduce exposure to UV in order to minimize risk of damage to our bodies due to ultraviolet radiation?

There are several ways:

Avoid going outside during the hottest part of the day.

Keep your body covered up during the day when the sun is brightest. (Natives to hotter countries do not go around in t-shirts and bikinis because they know better - unlike British people on holiday!)

Wear sunscreen to reduce exposure.

Wear sunglasses to protect they eyes from developing cataracts.
