Keeping hydrated for exercise
It might surprise you to know that when you exercise you can lose up to a litre of fluid in an hour, although the amount lost varies from person to person and depends on how long and how hard you’re exercising. You mainly lose fluid through sweating and in the air that you breathe out. If you don’t keep your fluid levels topped up, you will quickly become dehydrated, which can affect your health and ability to continue exercising. Therefore, it’s important to make sure you get the right amount of fluid before, during and after exercise.
