Individual protection against UV
When is sun protection necessary?
Time of year
You should generally be careful between late spring and early autumn when the sun's rays are most intense.
Time of day
Little UV radiation reaches the Earth during early morning or late afternoon hours. But during the four-hour period around solar noon UV levels can be very high.
The average British indoor worker experiences 30 per cent of his annual UV radiation exposure during the summer holiday and another 40 per cent during summer weekends. The story is similar for most other Northern European countries. Therefore, it is particularly important that you protect yourself well during these times.
Make sure you protect yourself against UV when you go skiing, do water sports or spend extended time on the beach. Spending a whole day out in the open exposes you to a lot of UV radiation, especially under conditions of strong ground reflection.
