A medical expert has said that drinking cold water is unhealthy because cold water generally decreases heartbeat rate and can lead to greater health complications.
In an interview with the News Agency of Nigeria(NAN) on Thursday, Dr Peters Irobo, the Chief Medical Director (CMD), Triumphant Hospital, Benin, said drinking cold water is not good for digestion as it causes the blood vessels to shrink, thereby slowing down the process of digestion.
Dr. Irobo said drinking tepid water has been proven to give the body more energy.
His words: “It will surprise you to know that drinking ice water or cold water can affect your heart. It can decrease your heart rate.
“According to some studies, drinking ice water may stimulate vagus nerve.
“The vagus nerve is an important part of the body’s autonomous nervous system and its main role is to control involuntary actions of the body.
“The vagus nerve mediates the lowering of the heart rate, and the low temperatures of ice cold water act as a stimulus to the nerve which causes the heart rate to drop.”
According to him, cold water affects digestion, robs you of nutrients, decreases heart beat rate and increases your chances of getting a sore throat.
