Uncle Xu was awakened by a sudden thirst, he groped his way to sit up from the bed, walked to the kitchen, and drank a large glass of cold water that had just been taken out of the refrigerator in one go.
However, not long after, Uncle Xu felt a churning in his stomach, and he felt so unwell that he finally had to call the emergency number and was rushed to a nearby hospital. When I arrived at the hospital, after a preliminary examination, the doctor quickly started a conversation with Uncle Xu. "Uncle Xu, you've been in the habit of drinking cold water in the middle of the night for a while, right?" The doctor asked as he checked the information.
Uncle Xu nodded, a little puzzled: "Yes, doctor, I've been doing this for so many years, and nothing big happened before, why is this time..."
The doctor smiled slightly and explained: "You see, Uncle Xu, our human stomach is very sensitive, especially at night, the blood flow and body temperature of the stomach will drop, at this time, suddenly drink a lot of cold water, the blood vessels in the stomach will shrink rapidly due to the sudden drop in temperature, resulting in stomach cramps, which is why you feel unwell now." ”
After hearing this, Uncle Xu suddenly realized: "Then I can't drink cold water in the future?" ”
The doctor shook his head and continued to explain: "It's not that you can't drink it, but there are some specific situations where it's best to avoid it. For example, in the middle of the night, or when you have just finished exercising, your body temperature is high, or you are eating some irritating food, drinking cold water may cause more irritation to your stomach at these times. ”
In further conversation, the doctor introduced to Uncle Xu that warm water is more easily absorbed by the body than cold water, especially when a quick rehydration is needed. Warm water is also less irritating to the digestive system and can help with better digestion.
"And," the doctor said in an accentuated tone, "while many people think that drinking cold water can help burn more calories because the body needs extra energy to heat up, the effect is actually very small." Therefore, from a health point of view, it is wiser to choose to drink warm water. ”
Uncle Xu was very surprised after hearing this, it turned out that his habits for many years were not scientific, and they may have caused harm to his body. He finally understood the doctor's kindness, and was very satisfied with this seemingly ordinary but scientifically based explanation.
Before leaving, Uncle Xu asked a question: "Doctor, if I am really thirsty at night, what should I do?" ”
The doctor smiled and replied, "Put a thermos flask at the head of the bed and fill it with some warm water." That way, even if you wake up in the middle of the night feeling thirsty, just drink some warm water. This not only relieves thirst quickly, but also avoids stomach irritation caused by cold water. Uncle Xu was very satisfied with this, thanked the doctor for his advice, and decided to change this habit in the future.
The doctor also shared that after the same environment and physical activity, people who drank warm water recovered faster and had more stable physiological indicators in their bodies than those who drank cold water. This shows that warm water is more conducive to the stability and health maintenance of the internal environment.
Doctors especially emphasize a point that people don't often notice: the time to drink water. He explained that drinking a lot of cold water suddenly before going to bed and waking up in the early hours of the morning may cause additional burden on the heart, especially for patients with cardiovascular disease.
Uncle Xu was deeply touched by the doctor's words, and he realized that although he had not felt obvious discomfort before, in the long run, such a habit may subtly affect his health. At the end of the discussion, Uncle Xu also asked a question: "Doctor, what if I drink something before going to bed at night?" ”
The doctor smiled and replied, "Uncle Xu, you can drink some warm water or mild herbal tea in moderation before going to bed at night, such as chrysanthemum tea, peppermint tea, etc." Not only does it moisturize your throat, but it also helps to relax your body and mind and fall asleep better. Of course, don't drink too much, so as not to get up and go to the toilet and affect the quality of sleep. ”
Uncle Xu decided to change his drinking habits when he returned home, and at the same time, he also wanted to share this valuable knowledge with his family and friends, so that everyone can have a healthier lifestyle.
