Take a bath several times a week.
In summer, the human body secretes heavily and sweats a lot, so it should be washed 1 time a day. The weather is not hot in winter, spring and autumn, and the number of baths can vary from person to person. Those who are obese and have exuberant sebaceous glands can appropriately increase the number of baths. The secretion of sebaceous glands in the elderly is reduced, and the number of baths can be appropriately reduced.
What is the proper temperature of the bath water?
The temperature of the bath water should be close to the body temperature, that is, 35 ~ 37℃. When the water temperature is too high, the blood vessels in the epidermis of the whole body dilate, and the blood flow in the heart and brain decreases, resulting in hypoxia. When pregnant women take a bath, the water temperature should not be too high to prevent fetal hypoxia and affect fetal development. Take a cold bath in summer. If the bath water is too cold, the skin pores will suddenly close, the blood vessels will contract sharply, and the heat in the body will not be emitted. Especially on hot nights, people often feel weak limbs, shoulder and knee pain and abdominal pain after taking a cold bath, and even become the inducing factors of arthritis and chronic gastrointestinal diseases. In summer, the water temperature of a cold bath is generally not lower than 10℃.
How long is the appropriate bath time?
No matter spring, summer, autumn and winter, the bath time should not be too long, and the bath time should be 15 ~ 30 minutes each time to prevent hypoxia and ischemia of heart and brain.
Under what circumstances should you not take a bath?
You shouldn't take a bath after a big meal or when you are hungry. Taking a bath after a full meal, the blood vessels in the epidermis of the whole body are stimulated by hot water to expand, more blood flows to the body surface, and the blood supply in the abdominal cavity is relatively reduced, which will affect digestion and absorption, cause hypoglycemia, and even collapse and faint.
You shouldn't take a bath when you have a fever. When the body temperature rises to 38℃, the body's heat consumption can increase by 20%, and the body is weak. Taking a bath at this time is prone to accidents.
You shouldn't take a bath after drinking. Alcohol can inhibit liver activity and hinder the recovery of glucose in the body. When taking a bath, the glucose consumption in the human body will increase. If you take a bath after drinking, your blood sugar can't be replenished in time, and you are prone to dizziness, general weakness, and even hypoglycemia coma in severe cases.
You shouldn't take a shower immediately after work. No matter after physical or mental work, you should take a rest before taking a bath, otherwise it will easily lead to insufficient blood supply to the heart and brain and even syncope.
Who shouldn't take a bath often?
Patients with cerebrovascular disease should not take a bath often. The thermal stimulation generated during bathing will accelerate the blood flow in patients, and then increase the pressure of blood on blood vessels. When blood flows through some local lesions, it is easy to rupture blood vessels.
Epilepsy patients should not take a bath often. When taking a bath, because a large amount of water vapor is inhaled into the body, the oxygen content in the body decreases, the sweat discharged from the body increases, and the electrolyte balance is disturbed, which is easy to cause temporary sexual dysfunction and induce epilepsy.
Old people should not take a bath too often. Old people's physical strength is weak, their skin becomes thinner, and their sebaceous glands gradually shrink. If they take a bath too often, their skin will easily become dry and cause itching. When taking a bath, the water temperature is too high, and the heat in the body is not easy to dissipate. It is also easy to cause telangiectasia and cause cerebral ischemia, dizziness and even fainting.
