In extremely hot weather, the fluid needs of an active person increase by about :
6 times normal
Exercise in heat greatly raises sweat production because evaporation of sweat is the main way the body loses heat. Sweat rates in hot conditions can reach 1–2 litres or more per hour.
A normal sedentary person needs about 2–2.5 litres of fluid a day, but an active person training in extremely hot weather may lose many litres, so fluid requirements can rise to about six times the normal amount.
Fluids must therefore be taken before, during and after activity to prevent dehydration, heat exhaustion and heat stroke.
Hence, the answer is 6 times normal.
