How do fluid needs change in hot weather?
As sweating rises the loss rises, and daily fluid intake goes up with it. The guideline recommends raising intake in situations where fluid losses increase.
In hot weather and in intense physical activity the fluid lost through sweating rises; this means the daily need rises as well. TÜBER, Türkiye's national dietary guideline, states that in situations where fluid losses increase, daily fluid intake has to be raised. The reference values are a starting point; on a hot day the adequate amount changes for the same person.
