Although it appears to you that a glass of water with ice helps to survive a heat stroke, scientists warn that its effect on the human body is totally different. The body uses more energy to regulate body temperature than it uses for digestion and absorption of nutrients.
The result of this process is loss of water and further heating of the body. Colder water slows down digestion, narrows blood circulation and hydration of the body is slowed down.
If you drink ice cold drink right after meals, it is very probable to get cold, even if it’s hot outside. This bad habit badly affects the secretion of saliva and reduces immunity.
When you get into the habit of drinking water at room temperature, you will notice a drastic improvement of digestion and you will feel better during and after meals.
