However, experts believe that drinking too much cold water or drinking it at the wrong time can affect digestion and overall health.
According to nutrition experts, cold water is not serious harm to healthy people, but can cause some people to have stomach cramps, bloating or indigestion, especially when drunk immediately after meals. Cold temperatures cause blood vessels to temporarily contract, thereby affecting the digestion process of food.
Some studies also show that drinking water that is too cold when the body is exercising vigorously or just came back from the sun can make the throat easily irritated. Dr. Donald Ford, a non-profit medical science center (USA), recommends taking small sips instead of drinking too quickly to avoid the feeling of "cold shock" for the body.
The important thing is not the water temperature but maintaining enough water every day. However, for people with digestive diseases, chronic sore throat or migraines, water at a cool or mildly warm temperature is usually more suitable.
To drink cold water safely, experts advise not to use water that is too iced in the early morning, when hungry or immediately after eating full. In addition, it is necessary to limit the habit of drinking many glasses of iced water continuously in a short time, as it can cause the body to temporarily lose heat balance.
