Dangers of Drinking Cold Water

Normally as individuals we love drinking cold water especially after a sunny hectic and stressful day, we need some cold drinks or water to refresh (revive) and cool our body.  But we need to know this and how to minimize the rate at which we take in cold drinks regularly.
According to Natural Law, our normal body temperature is about 98.6 degrees F. If we raise that temperature a few degrees, the body starts to show signs of distress, and we say we have a fever. We try hard to return to homeostasis or normal functioning.
Experts have said drinking cold water regularly could have negative impact on the heart and the digestive system. Food and healthy living expert say that cold water is at a temperature that contradicts the overall temperature within the body system.
Even though cold drinks or water has many health benefits, drinking ice water or cold water can only give temporary relief and drinking ice water regularly has its downside.

Here are some reasons why you shouldn’t drink ice or cold water:
1. Slows down digestion: Drinking ice water or cold water hampers the process of digesting food as it causes your blood vessels to shrink. This can slow down the process of digestion and as the food is not digested properly, the nutrients are lost or not absorbed by the body.
2. May lead to sore throat: Drinking cold water can cause the buildup of respiratory mucosa, which is a protective layer of the respiratory tract. When this layer gets congested, the respiratory tract is exposed and becomes vulnerable to various infections and hence the chances of your throat turning sore are high.
3. Shortage of nutrients: The body’s temperature is 37o C and when you drink something at a very low temperature, your body has to spend energy to regulate its temperature. This spent energy is otherwise used to digest food and absorb nutrients, thereby leaving your body short of nutrition.
4. Decreases your heart rate: Drinking ice water or cold water decreases your heart rate. Studies have shown that drinking ice water stimulates the vagus nerve.

Is cold water bad for the throat especially as a (singer)? 

Will cold water affect our throat / voice if we drink it before singing?

Also, in the long run (say if you drink cold water everyday), will cold water cause the throat / voice to be “lousy”?

Drinking cold water long-term won’t make your voice “lousier”. The whole idea behind singing is to have your vocal cords and surrounding muscles as loose as possible while singing. Hydration is a huge part of healthy vocal cords, so drink as much water as you can (hot, cold, or otherwise).

It’s just recommended that if you get thirsty either just before or while singing that you drink room-temperature water.

The reason for this is because when muscles get cold they contract. Contracted muscles = tension. Therefore drinking cold water before or while singing causes your vocal cords to tense up and cause a “lousy” sound.

The vagus nerve is the 10th cranial nerve and is an important part of the body’s autonomous nervous system that controls 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.

In conclusion, take water at a normal temperature, the brain is sensitive to temperature change which is why it freezes when one drinks cold water at first, adding that such continuous seizure is not good for it, more so that is why we advise people not to take drugs with cold water.

The drugs will not digest on time; it means you won’t get the best of the drugs because the water did not dissolve on time.
