Is it okay to drink ice water when you wake up in the morning?

There is a saying circulating on the Internet that if you drink a glass of ice water first thing when you wake up in the morning, you can achieve the effect of losing weight. Many people do not understand the reason and really think that they will lose weight, so they do it. However, after a period of time, their bodies are damaged. So is it good to drink ice water when you wake up in the morning? Let me explain it to you below.

Some people like to drink ice water from the refrigerator after getting up in the morning, and they think this is the most refreshing. In fact, it is inappropriate to drink such water in the morning, because the stomach and intestines are empty at this time. Too cold or too hot water will irritate the stomach and intestines and cause gastrointestinal discomfort. It is best to drink boiled water at room temperature in the morning. When it is cold, you can drink warm water to minimize irritation to the gastrointestinal tract. Studies have found that boiled water that is cooled to 20-25°C has specific biological activity. It can more easily penetrate cell membranes, promote metabolism, and enhance the body's immune function. People who are accustomed to drinking warm or cold boiled water have higher deoxygenase activity in their bodies, better metabolism, less lactic acid accumulation in muscle tissue, and are less likely to feel tired. Be sure to cover the boiled water when drying it the night before, because the boiled water will lose its activity if exposed to the air for too long.

When the weather is hot, the human body's blood vessels are in a state of expansion. If you drink a lot of ice water, it will inevitably cause the blood vessels to contract rapidly, resulting in insufficient blood supply to the cardiovascular and cerebrovascular systems, and causing cardiovascular and cerebrovascular diseases. Especially for patients with a history of hypertension, coronary heart disease and cerebrovascular disease, it will cause high blood pressure, induce angina pectoris and even myocardial infarction and cerebrovascular disease. Drinking too much ice water can also affect the development and physiological functions of the reproductive system, especially for some young girls. Regardless of whether they are menstruating or not, drinking ice water or cold drinks indiscriminately can cause menstrual disorders and dysmenorrhea. The accumulation of cold air in the uterus may even lay the root cause of infertility after marriage. Drinking too much ice water can also affect sperm development in boys. In addition, ice water can also cause harm to the throat, vocal cords, respiratory system, etc.

In fact, we do not recommend drinking ice water when the weather is hot. The temperature of ice water eventually turns into urine, which is warmed by body temperature. It is harmful to the body, especially for women. It is not recommended to drink ice water. Ice water reaches the stomach and then turns into urine, but urine is warm. Therefore, the body absorbs the temperature of the ice during the process of the ice water changing from ice to warm, which will cause physical weakness.
