The UV Index
indicates the strength of the UV radiation (Click here
to see the definition of the UV Index). The higher the number, the stronger
the UV radiation.
Protective Measures against UV Radiation
-
To reduce the harm from UV radiation, the most important
thing is to minimize direct exposure of the skin and the
eyes to sunlight.
-
On days when the UV Index is high, you should avoid staying
outdoors for prolonged periods.
-
If you must be out in the sun, take the following
precautions:
|
|
Check what the latest UV Index is. |
|
Wear a broad brim hat. |
|
|
Seeking shade under a tree. |
|
Wear UV blocking sunglasses. |
|
|
Use an umbrella. |
|
Use a broad-spectrum sunscreen lotion blocking both UVA and UVB (with a Sun Protection Factor (SPF) of 15 or above for UVB). Apply liberally and reapply after swimming or sweating. |
|
|
Wear long-sleeved and loose-fitting clothing. |
