Drinking ice water in the summer can cause dangerous health problems for the respiratory, digestive, or cardiovascular tract, such as a decrease in heart rate, increased risk of constipation or a sore throat, etc.
Numerous people think that drinking ice water can cool the body faster than drinking water at a normal temperature. However, experts have explained that drinking ice water or having ice cream when you just come back from the sun not only doesn't helps your body cool down but also makes you feel thirstier.
Comes with not helping the body to cool down deeply, but drinking ice water can cause you to have many serious health problems:
Acute pharyngitis, sore throat
There are several cases when after sipping ice colds cause you to suffer from sore throat and stuffy nose. The reason is explained by the cold ice will make the mucus in the mucosa of the throat dry, thereby causing your throat to burn cold with the expression of burning pain.
If you do not pay attention, your throat is highly susceptible to bacterial infection at this time causing acute pharyngitis.
Decreased heart rate
Your heart rate will probably beat more slowly after drinking ice cold water because the vagus nerve is stimulated and inhibited. This is the nerve that plays an important role in the autonomic nervous system of the body.
Therefore, the practice of drinking ice cold water in the summer makes the heart rate decrease and can be more severe if you keep this habit for a long time.
Increased risk of constipation
Your digestive system can be stimulated to work if you have a habit of drinking warm water - this is perfectly good. On the contrary, in the summer, if you drink ice regularly, it can cause discomfort in the digestive system, affecting the ability of the stomach and intestine to contract, especially after eating. Coldwater leads to a higher risk of constipation.
Drinking ice cold causes abdominal pain, nausea
Some people, after drinking cold ice, may experience abdominal pain or nausea and vomiting. Scientists have explained this mechanism as follows:
When cold water is passed through the throat to the stomach, the movement of blood vessels on the way shrinks and is difficult to circulate, the digestive tract is inhibited and it takes more time.
Loss of energy, exhaustion
As mentioned above, there are many notions that drinking ice or drinking cold water and eating ice cream have a cooling effect on the body but that is just an instant sensation. If a person goes back to the sun to drink cold water immediately, they may experience the phenomenon of "losing strength" immediately after a few seconds.
