Is drinking cold water harmful to the body?

When the weather is hot, no one likes to drink hot water because the temperature of hot water is too high. Not only is it very slow to drink, but it also does not quench your thirst. Many people like to let boiled water cool down and then drink the cold water directly when they are thirsty. However, some people believe that people should drink hot water, and cold boiled water is very bad for human health. So, is drinking cold boiled water harmful to the human body?

"Yin Qi" and "Yang Qi" are both theories of traditional Chinese medicine. Although it is difficult to divide them scientifically, the experience of our ancestors cannot be completely denied. The human body temperature is about 37°, and the internal temperature may be slightly higher. If you drink a glass of cold water with a temperature of only a few degrees, it will definitely take away a lot of temperature from your body, which is a relatively big stimulation. Morning is the time when the human body just recovers. The blood circulation, blood pressure, and internal organs are still recovering. If there is some internal stimulation at this time, it is easy to feel uncomfortable, and it is not impossible to cause some chronic diseases!

Morning is a special period. Not to mention the function of internal organs, some changes can even be measured by ourselves. If you don’t believe it, you can do the following experiment:

Measure your height before going to bed, and measure it again after waking up. You will be surprised to find that your height is taller in the morning than in the evening, and your weight is lighter in the morning than in the evening, and it is very obvious! This phenomenon shows that there are indeed significant differences in the functions and states of the human body at different times.

Therefore, it is right to drink less cold water in the morning. Don't give yourself such a big stimulation. Wouldn't it be better to drink some hot soy milk and milk? In addition, it is best not to wash your hair in the morning. Washing your hair in the morning will also stimulate the human body, causing more intense blood circulation and possibly causing headaches. If you go out without drying your hair after washing it, the water evaporates and takes away a lot of heat, which will almost 100% cause a headache!

In short, be gentle in everything you do in the morning. You can drink a glass of water, but not too cold; you can exercise, but not too intensely; you can eat meat, but not too greasy. All machines have a warm-up phase, and the human body should not be treated too casually.
