According to recommendations, each person should drink 1.5 to 2 liters of water per day. However, the habit of drinking too cold water, too much, and drinking a lot of soft drinks and sugar water can be harmful to your health.
Drinking too much water in a short period of time to quench thirst increases pressure on the circulatory system and kidneys, causing you to urinate a lot, causing electrolyte disorders. If the kidney’s ability to excrete water is exceeded (about 0.8-1 liter per hour), the body is at risk of hyponatremia, an electrolyte disorder that can cause brain edema and seizures in severe cases.
Neurological studies show that when the body is sufficiently hydrated, swallowing becomes significantly more difficult. This explains why many people find it difficult to continue drinking after drinking too much water.
In addition, you should not drink water that is too cold, especially ice water. Cold water can constrict blood vessels, disrupting blood circulation. Drinking ice a lot or for a long time damages the respiratory and nasopharyngeal mucosa, reduces mucus, and creates favorable conditions for viruses or bacteria to penetrate the mucosa, attack the body, and cause disease.
In particular, people with existing diseases such as asthma, chronic obstructive pulmonary disease (COPD), laryngitis, bronchitis… drinking ice cold water can damage the throat mucosa, exacerbating the symptoms of the disease.
When drinking water, you should drink slowly in small sips so that the body can respond and gradually bring water evenly to the organs, helping the absorption process go smoothly.
Many people drink coconut water and sugarcane juice instead of filtered water, which can cause electrolyte disorders, affect muscle function, and cause weight gain.
People with weak intestines, bloating and diarrhea should not use it regularly. People with underlying diseases such as diabetes, blood fat, gout need to limit.
When you are thirsty, you should not abuse carbonated or alcoholic drinks, which are not good for your health.
Drinking a lot of ice water in hot weather can easily shock the body and make you thirstier. Image: Today Show
