Staying safe in the sun
You could be at home or in the middle east. But certainly for the most of us we have these days a more cautious approach to the sun. With many scare stories of skin cancer over prolonged exposure to sunlight. It believed we are at a high risk now more than even due to the hole in the ozone layer.
It is always recommended that especially in a different climate that you cover up and maintain plenty of fluids providing you can access drinking water or purchase bottled water. And keeping in a shade can be a good idea.
Interesting, I recently read a report on the health benefits of being in sunlight (as opposed to artificial sun beds). It criticized the UK government of robbing us of much needed sunlight. Certainly it is true that all life needs sunlight, and why should humans be any different? Some recommend 10-15 minutes in sunlight even without any sun protection. So a little sun probably won't hurt, but a little means just that!
I often find that its so easy to get caught off guard when travelling. This includes especially in the lower season. I often get sunburned in New Zealand in Spring and late winter! Probably doesn't help switching hemispheres too. Another fact to consider when going long distance.
