Discuss juanc's answer to: Hydration for a run

During exercise, drinking should occur regularly for a good hydration, but the frequency of drinking and the amount consumed will depend on many factors, including the intensity and duration of exercise and the weather conditions, as well as on the physical characteristics of the individual, including body weight and individual sweating characteristics. In very hot and humid climates, outdoor sports should be performed in the early morning or late afternoon, and it is best to avoid unnecessary physical exertion during the hottest times of the day.
