For people with weak constitution, taking a bath in the morning is very easy to damage qi and blood. In the case of stopping hair loss and promoting the growth of qi and blood in the morning, bathing at this time will make qi and blood unable to stop growing, resulting in general weakness, chills in limbs, sneezing and dry cough. So people with weak constitution don't need to take a bath with cold water in the morning. After taking a bath, they must pay attention to wiping the water droplets of the human body immediately to prevent fever, colds and other discomfort.

Chinese medicine points out that the link of health preservation is to nourish the qi and blood of the human body, and qi and blood are generally derived from the sun. This link is to promote the qi and blood circulation of the human body, and the imbalance between yin and yang leads to problems in the human body. So this is also the reason why Chinese medicine attaches great importance to the balance of yin and yang. If a person's yang is insufficient, he will feel cold even when standing in the sun, and at the same time he will have symptoms of palpitation and shortness of breath. Generally speaking, this situation is easy for women, because women dominate the yin.

Patients with cardiovascular disease and diabetes try not to take a bath on an empty stomach when they wake up in the morning, which is prone to chest tightness, shortness of breath and hypoglycemia. For ordinary people, when they get up in the morning to take a bath, the temperature of water must be adjusted to a suitable ambient temperature, neither too high nor too low, so as to prevent the exhaustion period of the human body caused by the high temperature of stopping water and the cold symptoms caused by the moisture invading the epidermis caused by the low temperature of water. Generally, it is necessary to prevent taking a bath on an empty stomach, after meals and when the body is not in time. You can't take a cold bath immediately after exercise.

Shower in the morning can refresh your mind, but cold and dampness can also be eroded inadvertently. Some Chinese medicine practitioners think that taking a bath in the morning hurts their vitality. Because qi and blood rise in the morning, bathing will consume a lot of qi and blood. This is equivalent to a day when qi and blood are useless and have been spent. Then there are things that have to work all day and are in a hurry, and only the blood in the inventory is consumed. Also, taking a bath before eating in the morning is equivalent to consuming kinetic energy first and then replenishing kinetic energy. Therefore, it is very easy to lead to deficiency of qi and blood and physical weakness.
