Curejoy Expert Dr.Janardhana Hebbar Explains:
Very cold ice water or very hot water is not good for anyone. Moderately cold water is good for people living in hot and humid places. For those having Pitta (fire) body type, people who suffer from excessive sweating, burning sensation during summer, ice water is a good option. Cold water is also said to be absorbed more quickly than hot water in the body after or during exercise and helps in preventing dehydration.
Luke warm water is ideal for those who suffer from cough, cold, asthma, allergic attacks and people who feel that their hands and feet are cold. It is also great for those who live in cold climatic conditions or during winters. Warm water is said to remove built up deposits that are responsible for creating negative thoughts and emotions in our nervous system. Thus it helps in effective removal of toxins which leads to better clarity of mind.
It is considered ideal to take a cup of warm water usually one hour after dinner, if you are a normal, healthy person without any of the above mentioned afflictions.
Note: The water must not be so hot that it can scald your mouth and throat, but it should be warm enough to produce a mild perspiration.
