sun and its effect

SUN AND ITS EFFECT

The short-term effects of excessive sun are serious enough by themselves. Of course, spending time in hot countries generally increases your likelihood of becoming dehydrated - a potentially serious condition - but direct sunshine can be much more dangerous.

The sun can be harmful very rapidly in some places. A hot summer sun in relatively northern climes is safe only for up to 40 minutes, and hotter areas of the world are, of course, much less safe.

The sun affects some people more than others. In particular, those with fair or freckled skin (and usually blonde or red hair). People with dark hair and dark skin are less likely to suffer from sunburn. People with black skin are likely to be not affected by the sun, and yellow and brown-skinned people are much less likely to suffer than white-skinned people. All colours of skin do burn however, given enough time.
