Does temperature of drinking water affect health?

Yes, the temperature of the water you drink is important for maintaining normal health.
Cold water from natural sources (which is not cooled in a refrigerator or with ice) is fit for drinking because of the following reasons -

=> It lowers the body temperature
=> It dilutes the blood, to the required consistency
=> promotes excretion of poisons from the skin in the form of evaporation
=> stimulates the normal function of the kidneys and therefore increases the rate of removal of poisons from the body through the urine.
=> increase movements of the intestines, thus facilitating formation and passing of soft stool

So think before you drink ,
