To avoid dehydration, how many hours before strenuous exercise should you start to slowly consume fluids?

4 hours

Explanation:

Lack of water affects your health in several areas and your training is one of them. There are, however, more serious cases where the lack of water results in more than a little discomfort. It affects the functioning of the heart and other organs, and impairing the training itself and making you not get the benefit you should have from your physical activity. The solution remains the same: if you are thirsty, drink water and never let your body suffer from extreme dehydration, a problem that occurs mainly in athletes who train daily and always with a lot of effort.

To avoid dehydration, you should start drinking water at least 4 hours before your training begins, but it is important that you drink water during training as well.
