As rewarding as cold water can be, in hot weathers like ours, experts say that it comes with serious health consequences. Our response to drinking cold water varies depending on a number of factors; drinking cold water can lead to negative impact on the heart and the digestive system.
Dr. Chidoze Mapama a Medical doctor at Obafemi Awolowo University Teaching Hospital (OAUTH) said drinking cold water is good during heat period, but drinking it regularly can have negative impact on the heart and the digestive system.
He said drinking cold water has a way of bringing down the body temperature. It has a way of slowing down the heart. It causes the blood to clot. That means the blood becomes thick and not able to flow freely through the organs. The normal human body was accustomed to 34 degrees Celsius and 37 degrees Celsius.
Drinking too much of cold water has been said to have adverse effect on the heart and digestive systems of humans. Falling into cold water, cold receptors in the skin cause immediate physiological responses, the first of which is a “gasp” reflex. If this happens when your head is under water, you are in deep trouble.
When we drink cold water, juice, or any cold fluids, we create the basis for chronic heart diseases. Cold water has a clotting effect on the blood and other fluids in the body making it difficult for it to circulate. A body that cannot circulate its blood is like an uninviting swimming pool in which moss and bacteria grow. The blood may be thick, unable to flow properly to the extremities of the body, the hands and feet begin to feel numb and hurt, the toes begin to hurt, and the toenails lose their shine and may begin to decay. The heart labours to pump the blood throughout the body, and the lungs fight to keep up. He added
He however concluded that those who regularly consume cold water may experience shock which can lead to some diseases due to the sudden change in temperature levels.
