The consequences of a slight dehydration
Jenny Montlahuc
Most of us know that thirst is a late indicator of dehydration and you should try to drink before you get thirsty.
A lack of water can lead to headaches, a dry mouth, a lack of concentration or constipation. And this is just for us ordinary folks. For those doing lots of exercise, dehydration can seriously impact your performance. Try to drink the recommended 1.5 litres of water every day. Increase this amount if the weather is hot or you’re exercising a lot. Drinking this amount should help you avoid the headaches etc.
