The hazards of drinking cold water for a long time are as follows:
1. Cough and cold
Drinking more ice water not only causes the body temperature to drop rapidly, but also easily irritates the throat and bronchi, causing discomfort such as cough and bronchitis. Chinese medicine believes that drinking ice water is also easy to cause cold evil to invade the lungs and make people cough, which is more likely to catch a cold.
2. Abdominal pain, diarrhea
A large amount of drinking ice water will stimulate the gastrointestinal tract, accelerate the gastrointestinal motility, and sometimes even cause gastrointestinal spasm, leading to abdominal pain. The time of food in the gastrointestinal tract is too short, digestion and absorption are not complete, causing bloating and diarrhea.
In the hot summer, eating is a kind of torture, but people can’t stop eating. People tend to have ice drinks while eating, or drink ice water after meals to ease the heat of eating. But people don’t know, a lot of ice water into the stomach can easily cause vasoconstriction of the gastric mucosa, reducing the activity of many enzymes in the stomach and causing indigestion.
4. Easy to get stomach disease
Drinking more ice water not only stimulates the intestines, but also stimulates the vasoconstriction of the gastric mucosa, which can easily lead to gastric ischemia and hypoxia, and is prone to gastritis or recurrence of stomach diseases. Drinking ice water often can easily affect the digestion of the stomach.
5. Cause angina
Drinking too much ice water may also cause irritation to the cerebral blood vessels, causing cerebral blood vessels to contract and paralyzed, which may easily cause angina. Especially for middle-aged and elderly people who have cardiovascular disease themselves, it is best not to drink ice water.
