Hot water bath is the most common way to take a bath. You can take a bath in the bathtub, under the shower head, and sometimes in the bathroom. If possible, taking a hot bath before going to bed every day is very beneficial to your health.
The role of hot water bath
Hot water bath can clean the skin and improve its disease resistance. There are millions of sweat gland openings on the human body surface, and the sweat discharged from the skin every day is about 1000mL. In strenuous activities or summer, you sweat more. There are sebaceous glands on the skin, which often secrete oily substances and mix with sweat and dust to form dirt. When dirt accumulates to a certain extent, it can block the opening of sweat glands, promote the growth of bacteria, and sometimes cause dermatoses such as sweat spots, folliculitis, furuncle, carbuncle and impetigo. Bathing with hot water can remove dirt from the skin, keep sweat glands unobstructed, and improve the metabolic function and disease resistance of the skin. The clean skin surface is acidic and can inhibit the growth of bacteria. Some people have done experiments, and taking a hot bath can remove tens of millions or even hundreds of millions of microorganisms from the skin. Therefore, hot water bath is called "disinfection hot bed".
Hot water bath can promote metabolism and eliminate fatigue. Hot water bath can improve the excitability of nervous system, lead to vasodilation, promote blood circulation and improve the nutritional status of tissues and organs. At the same time, it can also reduce muscle tension, relieve muscle spasm, relax muscles and eliminate fatigue. Lactic acid content in blood is a sign of fatigue. When the lactic acid content in the blood increases after work or exercise, people will feel tired. Taking a hot bath can speed up metabolism and increase the speed of decomposing lactic acid.
Hot water bath also has therapeutic effect. Clinically, it can be used to treat chronic diseases such as early cold, chronic arthritis and fracture healing. In addition, a hot bath has a calming effect. For people with poor sleep or frequent insomnia, bathing before going to bed can promote sleep and improve sleep quality.
Avoid hot baths.
First, pay attention to the water temperature. When taking a bath, the temperature of water depends on everyone's physical condition. Generally, the temperature of hot water bath should be controlled between 38℃ and 42℃. If the water temperature is too high, it will make it difficult to dissipate the heat in the body, which will lead to sweating. Excessive sweating will easily hurt body fluids, and if it is attacked by cold wind after bathing, it will easily lead to diseases. If the water temperature is too cold, the body will suddenly get cold, which is also the root cause of the disease. Therefore, the "Dry Gold Fang Yao" said: Bathing "can't be too hot or too cold, which will cause all diseases."
The second is to control time. Bathing time should not be too long. Staying in the bathroom for too long will lead to excessive physical exertion and insufficient oxygen supply, thus inducing angina pectoris or elevated blood pressure. People suffering from coronary heart disease, hypertension or cerebrovascular sclerosis should pay more attention to the fact that bathing time should not be too long, and it is best to take a shower to avoid cerebrovascular accidents or myocardial infarction.
Third, it is not advisable to take a bath when you are hungry. As the saying goes, "the belly is empty, flustered and short of breath." When people are hungry, the body's calories decrease and blood sugar decreases, while bathing itself consumes a lot of calories, which is mainly supplemented by glucose oxidation in the blood. Therefore, bathing in a hungry state is prone to dizziness or even fainting caused by hypoglycemia, commonly known as "dizziness". On the other hand, after full bathing, the superficial blood vessels of the whole body are expanded by hot water, and the visceral blood such as gastrointestinal tract will be mobilized and distributed to the body surface. Gastrointestinal tract and other digestive organs have insufficient blood supply and their functions are affected, which is easy to cause indigestion.
