Humidity also matters. In wet surroundings you sweat more, but the body less effectively cools by it. Like this grows the need of water.
Before plan trip can be tricky. Easily you takes too a lot or too little of water on montripo. Unfairly sufficient amount necesas for stay hidrata during the whole way.
On the other hand, too heavy burden of water is problem because it weighs a lot. The calculator helps to estimate as far as fill according to temperature, distance and laborgrado. Like this you escapes to despisie the consumption and take too little.
For tuttaga montripo the right amount is inherent. Neither sufficient trinkado can cause many problems even death in gross cases. Well think about basic needs of hidrigo and correction for lost liquor.
