Dehydration
In hot weather, or if you have had diarrhea, you will need to take care not to become dehydrated.
Symptoms of dehydration include thirst, a dry mouth, headaches, dark colored urine and tiredness. It helps to avoid strenuous exercise during the hottest hours and to drink plenty of non-alcoholic liquids (at least 8-10 average glasses).
More information on how to avoid and treat dehydration is given in the section Managing Dehydration.
