The main climate characteristics of autumn are dryness, lack of water in air and human body. However, drinking boiled water alone cannot completely resist the negative effects brought by autumn dryness. In ancient China, there was a good diet to deal with autumn dryness: "Salt water in the morning and honey soup at night." In other words, drinking boiled water is easy to lose water. If you add a little salt to boiled water, it is not so easy to lose water. Drinking salt water during the day and honey water at night is not only a good way to replenish human body's water, but also a good diet for health preservation and anti-aging in autumn. At the same time, it can also prevent constipation caused by autumn dryness, which really kills two birds with one stone.

Honey is a gift from nature. It is rich in nutrients, mainly glucose and fructose, with a content of 70%. In addition, it also contains protein, amino acids, vitamin A, vitamin C and vitamin D, etc. Honey has the functions of strengthening physique, improving intelligence, increasing hemoglobin and improving myocardium, and can prolong life if taken for a long time. Modern medicine has proved that honey is effective for neurasthenia, hypertension, coronary arteriosclerosis and lung disease. Taking honey regularly in autumn is not only beneficial to the recovery of these diseases, but also can prevent the injury of autumn dryness to the human body, and play a role in moistening and nourishing the lungs, thus making people healthy and live longer.
