First of all, there must be a concept of "hot water". how much is it? According to the general definition, warm water is 20-40 degrees, and hot water is above 40 degrees 100 degrees (the normal maximum temperature is this, with proper names such as "boiled water", "boiled water" and "boiled water").

Usually our common hot water is about 40-50 degrees (even higher usually causes discomfort, so no one should be so stupid).

Let's talk about "cold water". In fact, it is cold water below warm water, but it generally refers to cold water in life, usually between 0- 10 degrees. Drinking cold water for a long time is easy to stimulate the stomach and cause some physical discomfort.

Finally, back to the topic, drinking hot water above 50 degrees may cause burns and other problems. Let's not discuss it. The temperature between 40 and 50 degrees is obviously higher than the body temperature, refer to this hot water. Drink such hot water (in fact, it may burn if the temperature is above 44 degrees, but people will naturally drink hot water until the temperature is low). Generally, because of the high temperature, everyone will drink saliva, which is a good drinking habit. In addition, people who drink hot water are generally in autumn and winter. People with colds and dysmenorrhea are often accompanied by cold hands and feet. A cup of hot water in your hand can also warm your hands, what's more, drinking it can replenish water shortage and relieve your body from cooling down.

To sum up, warm water can be used daily, and the temperature can be slightly higher when you catch a cold, but it is a protective measure and does have certain benefits for relieving symptoms (but some special circumstances will aggravate symptoms). When it comes to "treatment", it is a bit profound.
