Five notes on scientific bathing
After all, bathing is a very personal behavior, and many people follow their own inclinations.
However, whether in order to keep clean or beautify yourself, we must understand the relevant rules and regulations if we want to give full play to the best effect of bathing.
Improper bathing methods may bring extra fatigue. How to enjoy a more pleasant bath time?
What is the ideal order of bathing?
If bathing is for health, we must pay attention to scientific methods.
First of all, considering the adaptation of the heart, from foot bath to shower, the body should gradually adapt to the water temperature.
Then soak in the bathtub and wash your whole body. When soaking, the body will sweat a little, making the dirt easier to wash off.
Then wash your hair, wash your whole body from your feet, and then soak in the bathtub.
The shower should be put at the end, although the shower also has the effect of * * *. If you take a shower after the shower, the effect of the shower will be offset by the whole body water pressure of the bathtub.
What is the appropriate water temperature?
Some people like hot water, while others like warm water. Because of physiological conditions, 40 degrees is an important boundary. Hydrology of about 37~39 degrees is less harmful to the body, and parasympathetic nerves will play a role in relaxing the body and mind. If the water temperature exceeds 40 degrees, the temperature will strengthen the physique and the sympathetic nerve will play a role. Its function is to get the body and mind excited.
If there is no water temperature indicator in the family bathtub, it is best to measure it with a thermometer before taking a bath.
How long will it take?
The length of bathing depends on the temperature. Many people can't soak in hot water above 40 degrees for a long time. Basically, the longest soaking time is 3 minutes at 42 degrees, 40 degrees 10 minutes, and 20-30 minutes at 37-38 degrees.
When should I not take a shower?
First of all, it has something to do with eating. After a meal, blood is concentrated in the digestive system. At this time, bathing will improve blood circulation and reduce the blood supply of digestive system, thus affecting digestion. It is best not to take a bath for two hours after a meal. In the same way, after strenuous exercise, blood is concentrated in the muscle area, so don't take a bath or shower. If you drink too much, you should avoid taking a bath immediately.
Question 2: What is the best time to take a bath? It is necessary to determine the bathing time according to the water temperature, especially for people with poor health. Many people can't soak in hot water above 40℃ for a long time. Soak at water temperature above 42℃ for 3-5 minutes, at 40℃ 10 minute, and at 37℃ to 39℃ for 20-30 minutes. People in poor health should try not to soak in water when taking a bath. Measurements show that when an adult lets hot water reach his shoulders, the water pressure of his whole body will reach about 500 kilograms. This may make people feel uncomfortable in the heart and lungs, and the body is also burdened. You can soak your body in your ribs and keep your heart and lungs out of water. The heating effect of water temperature can stimulate the "continuous circulation in the body" system and promote blood circulation. Hot water can also promote sweat to be discharged from pores together with waste in the body, which has a cosmetic effect on the skin. A healthy person can immerse himself in water when taking a bath. The displacement of the body makes him lose weight, reduce muscle tension, relax physically and mentally, and improve his sleep.
So when is the best time to take a bath?
1, 7: 30 in the morning-get up and take a shower.
Taking a bath for 5 minutes after getting up can help people's brains and organs get up quickly, so that even if they sleep for a short time on the first night, they can be refreshed all morning.
Note: Because the body's protection is weak, the body surface lacks protection at night, and moisture can easily enter the body, so it is not too late to take a bath at night.
2. Take a bath 2 hours before going to bed
People who have the habit of taking a bath before going to bed should finish it 2 hours before going to bed. Two hours before going to bed can not only wash away the fatigue of the day, but more importantly, it will not affect sleep.
Because drowsiness often occurs after the body temperature drops, hot water bath will raise the body temperature and delay the release of "sleep hormones" by the brain. Therefore, if you want to fall asleep quickly, you'd better not take a bath before going to bed, but two hours in advance.
If you must take a bath before going to bed, you can cold compress your forehead with a wet towel for 5 minutes after taking a shower to let your body temperature drop to normal level before going to bed.
Question 3: How often do you take a bath? People in poor health should try not to soak in water when taking a bath. Measurements show that when an adult lets hot water reach his shoulders, the water pressure of his whole body will reach about 500 kilograms. This may make people feel uncomfortable in the heart and lungs, and the body is also burdened. You can soak your body in your ribs and keep your heart and lungs out of water. The heating effect of water temperature can stimulate the "continuous circulation in the body" system and promote blood circulation. Hot water can also promote sweat to be discharged from pores together with waste in the body, which has a cosmetic effect on the skin.
A healthy person can immerse himself in water when taking a bath. The displacement of the body makes him lose weight, reduce muscle tension, relax physically and mentally, and improve his sleep.
Be wary of taking a bath after drinking.
Drink some wine and take a hot bath. That sounds beautiful. In fact, it is easy to cause cardiovascular disease.
Cardiovascular experts believe that after drinking, due to the accelerated blood circulation, the glucose stored in the body will be consumed in large quantities during bathing, resulting in a rapid drop in body temperature. At the same time, alcohol inhibits the normal physiological activities of the liver and hinders the recovery of glucose storage in the body, which is easy to lead to shock and can be fatal in severe cases. Therefore, Dr. Wang also reminded everyone that it is best not to take a bath immediately after drinking. "Some people mistakenly think that taking a hot bath can relieve alcohol, but in fact it will only aggravate heart ischemia." When you have dizziness, chest tightness, dizziness and other "bathhouse syndrome" during bathing, you should also stop bathing immediately and go to the hospital for treatment.
Take a bath to prevent "heatstroke"
Heatstroke is a disease characterized by dysfunction of thermoregulation center and disorder of water and electrolyte caused by high temperature. It is advisable to take a bath in half an hour.
Many people think that heatstroke will only happen in the summer when the sun is shining, but bathing in winter may also happen.
It is very cold in winter, and many people like to take a bath. In public bathrooms, if you take a bath for too long, you will feel chest tightness, shortness of breath, dizziness and even syncope. This is the same principle as heatstroke. The bathroom doors and windows are closed, and the indoor humidity is higher than the outside. At first, the human body was very comfortable, the muscles relaxed and the skin capillaries expanded for a long time. There is a lot of blood flowing on the body surface, the blood flowing back to the heart is insufficient, and the cardiac output is reduced, which leads to insufficient blood supply to the internal organs and is prone to syncope and other accidents.
If you want to take a bath in the bath, you'd better take a bath in the warm pool first, and then transition to the hot pool. Slowly enter the water, starting from the lower limbs and gradually entering the water. Don't take a bath immediately after meals; Pay attention to ventilation in the bathroom; It is not advisable to take a bath during menstruation, pregnancy, hunger and drinking; Eat properly within 30 minutes after washing.
When taking a bath "heatstroke", the patient should be transferred to a ventilated and cool place and take light salt water orally; Patients with hypertension and coronary heart disease, if they feel chest tightness and shortness of breath, can press Renzhong point, take quick-acting Jiuxin Pills and seek medical advice in time.
Appropriate addition of "ingredients" helps to alleviate the lack of aesthetic feeling.
When you take a bath, your pores are open. At this time, adding some "ingredients" to hot water can have different effects.
After soaking in hot water, the pores of human skin open. At this time, putting appropriate Chinese herbal medicines into hot water can enter the human body along the pores, which has a good health care effect on the body.
Question 4: How long does it take to take a bath? No matter spring, summer, autumn and winter, the bathing time should not be too long. The appropriate time for each bath is 15~30 minutes to prevent hypoxia and ischemia of heart and brain. The water temperature is above 42℃, and the bathing time is 10~20 minutes. The water temperature is 35~37℃, and the soaking time can be longer.
Question 5: What's wrong with taking a bath for too long? Ahem,
I'll tell Mao
Listen:
As it is very cold outside, I want to soak for a long time as soon as I enter the bathroom. Entering cold weather, many people have this idea. However, judging from the situation in previous years, a considerable number of people accidentally fainted, poisoned and went into shock because of taking a bath in winter, including many elderly people with chronic diseases. In this regard, experts remind that bathing in winter must not damage health for enjoyment.
High water temperature leads to anoxic halo bath.
Taking a bath in a hot bath in winter, especially in a hot tub for a long time, some people will suddenly have dizziness, nausea, vomiting, sweating and other symptoms, and in severe cases, they will faint in the bathtub. It is understood that every winter there will be accidents that cause casualties because of "halo bath".
According to Professor Jiang Jinqi, director of the emergency department of Shanghai Chest Hospital, the main reasons for "halo bath" are high humidity, dirty air and lack of oxygen in the bathroom. Take a bath in the bath and go to the lounge to breathe fresh air from time to time; Don't take a shower at home. The water temperature is too high and the time is too long. After washing, open the window as soon as possible to ventilate and disperse harmful gases.
Long-term bathing causes cardiovascular diseases.
Professor Yu Qingfu from School of Public Health, School of Medicine, Fudan University pointed out that it is inappropriate for many people to take a long hot bath in winter. For the elderly with chronic diseases such as hypertension, arteriosclerosis and coronary heart disease, taking a long bath is a dangerous behavior. With the scouring of hot water, the capillaries of the whole body dilate, and a large amount of blood dilates the blood vessels on the body surface, and the blood of important organs such as the heart and brain is relatively reduced, so accidents such as myocardial infarction are prone to occur.
Poor ventilation is easy to gas poisoning.
In winter, the doors and windows of bathing at home are closed, and the ventilation is not smooth, which is easy to cause gas poisoning. Experts in the hyperbaric oxygen chamber of Shanghai Changhai Hospital reminded that it is necessary to strengthen the maintenance of the gas water heater at home in winter, and the gas valve must be closed when not in use. It is best to use stainless steel bellows for liquefied gas, and the gas hose in the pipeline should be replaced regularly. If there is a red fire, it should be cleaned and repaired in time.
If gas poisoning is found, open the window quickly and move the poisoned person to a place with fresh air. If he is seriously ill, he should be sent to hospital for treatment.
