1, long life hot and cold water bath method
The method of hot and cold bath is very simple, that is, take a bath with hot water before going to bed every day, and the water temperature is limited to what the body can bear. "Sleep" in hot water after washing 15 minutes. After taking a shower, I broke out in a big sweat as usual. After 3 ~ 4 minutes, enter the cold water basin or take a cold shower.
Hot and cold baths must be "hot before cold". Ma Lao summed up the bathing method of "heating first and then cooling" into three advantages through his own personal experience: first, when taking a bath with hot water, the pores of sweat glands in the whole body expand, and the dirty things in the body are excreted with sweat; Second, hot water makes blood smooth, promotes metabolism and makes people refreshed; Third, the blood vessels of the whole body expand by taking a hot bath and contract by taking a cold bath. Blood vessels contract in this way, and their elasticity is enhanced, so it is not easy to harden and blood pressure is not easy to rise, which can prevent stroke in the elderly. This is indeed the reason for Ma Lao's longevity.
2. Who is not suitable?
In order to live a long and healthy life, you may wish to apply the longevity bath method. But it is worth noting that people who are used to taking a hot bath at ordinary times should not take a cold bath immediately after taking a hot bath. They should take a hot bath first and then gradually lower the water temperature. After a period of adaptation, they should adopt the long-lived bathing method of "heating first and then cooling".
3. Precautions for bathing in winter
1, long hot water bath time
When the weather is cold in winter, many girls like to soak comfortably in hot water and are unwilling to leave. But this is not a good habit. Taking a bath for too long in winter will make the skin surface lose oil protection, cause symptoms such as dryness and itching, and also cause skin wrinkling and dehydration.
Moreover, people who bathe for a long time are prone to fatigue, heart ischemia and hypoxia, coronary artery spasm, thrombosis, and even serious arrhythmia and sudden death. In addition, if the bath time is too long, the blood supply to the head will be reduced accordingly, which will easily lead to cerebral ischemia and accidents.
Suggestion: Take a bath for 20 minutes and take a shower for 3 to 5 minutes.
2. The higher the bath temperature, the better.
In the cold winter, many people like to take a bath with very hot water, and even think that the hotter the water temperature, the higher the body heat. But the bath water temperature is too high, which will make your skin miserable.
Too high water temperature will destroy the oil on the skin surface, lead to telangiectasia and aggravate the dryness of the skin. At the same time, too high temperature will also increase the burden on the heart, because the blood vessels in the whole skin are obviously expanded, so that a large amount of blood flows to the whole skin, which will make the heart ischemic and hypoxic.
Suggestion: Water temperature is 24℃ to 29℃.
3, bathing on an empty stomach is easy to collapse
Back home, many people like to take a bath first and then sit down and enjoy dinner, but there are also health risks behind this behavior.
When taking a bath, because of the rapid heat transfer of water, people will consume a lot of heat, and the heat of the human body mainly comes from glucose in the blood. When hungry, the blood sugar level is low, which can not meet the energy demand, and it is prone to hypoglycemia, fatigue, dizziness, palpitation and even collapse.
Suggestion: Don't take a bath on an empty stomach, at least have a drink before taking a bath.
4, strong bath will stimulate the skin.
The skin is dry and fragile in winter. If you use a bath with strong cleaning ability, it will aggravate the damage to the protective layer of the skin and aggravate the skin problems.
When taking a bath in winter, choose a mild bath product to avoid irritating the skin. The bath we choose must be alkaline and neutral.
It is best to apply a layer of moisturizing skin care products after wooden fish. You must drink a lot of water every day. You can also put a basin of water in the room or use an air humidifier to increase the indoor humidity. If necessary, you can spray some water on your skin every few hours to keep it moist.
5, often take a bath, clean
Many people think that the more times you take a bath, the cleaner your body will be. However, with the coming of winter, the skin is becoming more and more dry and fragile, and skin itching is also easy to target these "bathing families". Some people even think that skin itching means that personal hygiene is not in place, so bathing is more diligent and thorough, but the degree of skin itching is aggravated.
Taking a bath too often will wash away the oil secreted by the skin surface and the protective flora that normally parasitize the skin surface, which will easily damage the stratum corneum of the skin, lead to itchy skin, weaken the skin's resistance and make it easy to get sick. Rubbing hard will also damage the fragile epidermis, and bacteria and fungi will take advantage of it and cause skin infection.
6. Bathing after meals aggravates heart ischemia.
Some women take a bath immediately after meals in order to save time, which is very dangerous. On the one hand, after each meal, the human body should transfer some blood from the whole body to the gastrointestinal tract to help digestion. Taking a bath immediately after a meal will affect the digestion and absorption of food because of the low blood flow in the digestive tract, cause gastrointestinal diseases, and induce symptoms such as nausea, vomiting and upper abdominal pain.
In addition, due to insufficient blood supply to the brain, heart and other parts, cardiovascular and cerebrovascular accidents are easily induced. On the other hand, it will aggravate heart ischemia and even cause angina pectoris or sudden death.
Suggestion: The bath time should be about two hours after a meal or 1 hour before the next meal.
7. Pay attention to the order of bathing
The low temperature in winter makes the blood vessels of human skin contract, while the temperature of bath water in winter is relatively high. Warm water suddenly comes from the beginning, which will make the human body's regulatory system "unprepared", leading to the sudden expansion of blood vessels in the head and whole body, and a large amount of blood concentrated on the skin surface, leading to acute ischemia of important organs such as the heart and brain, dizziness, chest tightness and other discomforts will also come to the door.
Acute myocardial ischemia can lead to cardiovascular spasm, angina pectoris and even acute myocardial infarction. Acute cerebral ischemia is prone to "stroke" symptoms such as hemiplegia and aphasia; The blood pressure of patients with hypertension will suddenly drop, causing discomfort such as dizziness and palpitation, and even syncope.
Suggestion: The correct way to take a bath in winter is to wash your feet with hot water before taking a bath, and then slowly pour water on your body when your feet are warm, so that your body can have a gradual adaptation process.
8. Close the doors and windows when taking a shower.
Many people like to close the doors and windows when taking a bath in winter, so as to prevent the cold air from sneaking in. However, if you use a gas water heater to take a bath, this behavior can easily lead to carbon monoxide poisoning.
Closed doors and windows lead to carbon monoxide poisoning every year. Taking a bath with a gas water heater is inherently risky. If it is not properly installed and maintained, it will bring danger, especially when taking a bath, which is very prone to carbon monoxide poisoning. Bathing in winter, doors and windows are better sealed, and people are prone to hypoxia and poisoning.
Suggestion: Don't close the doors and windows when taking a bath. Be sure to come and have a look, more than half an hour. Otherwise, poisoning for more than half an hour will be life-threatening.
Suggestion: Bathing in winter should not be too frequent, 2-3 times a week.
9. Go to bed after taking a shower
Don't fall asleep immediately after taking a shower, because the body temperature will rise after taking a shower, which is not conducive to the secretion of melatonin, a hormone that helps sleep. Sleeping with wet hair on a pillow is easy to have a headache, which seriously affects the quality of sleep.
10, you can't take a shower after strenuous exercise.
Taking a bath after strenuous exercise can easily lead to insufficient blood supply to the heart and brain. Don't take a bath immediately after work or fatigue.
1 1, don't take a shower immediately after drinking.
Never take a bath immediately after drinking, because when taking a bath, the glucose stored in the human body will be consumed in large quantities due to physical activity and accelerated blood circulation. Alcohol will inhibit the normal physiological function of the liver, so that the stored glycogen cannot be converted into glucose and replenished to the blood in time, thus significantly reducing the blood sugar content.
Taking a bath after drinking can easily lead to dizziness, dizziness, general weakness and other symptoms, and even cause shock in severe cases.
Suggestion: It is best to take a bath about 2 hours after drinking.
12, don't rush to take a bath before and after massage.
Massage can not only relieve fatigue and tension, but also relax muscles and tendons and refresh the mind. However, many friends who often massage ignore a question, that is, take a bath before massage or after massage?
People who like to take a bath before massage think it is convenient and quick to rest immediately after massage; People who take a bath immediately after massage think it is safer and healthier. In fact, these two methods are not desirable, because whether you are doing essential oil massage or aromatherapy SPA, the masseur uses nourishing or catharsis, and you can't take a bath for an hour before and after massage.
13, the protective layer of skin is damaged by the washcloth.
Don't use too many bath towels when taking a bath, especially don't use nylon. When rubbing the skin, it will destroy the protective layer of the skin, leading to minor trauma and skin diseases. Rubbing hard will also consume a lot of physical strength. Try not to take a bath when you have skin damage, so as not to aggravate the infection.
Four main points of correct bathing
1. British Times (1785)
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.
2. Water temperature
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.
3. 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.
Step 4: Order
The correct bathing order, you know? It is said that 99% of people are wrong.
Bathing is not only related to major events such as beauty, but also plays a good role in eliminating fatigue and improving sleep. But you may not know that bathing has a correct order: washing your face, taking a bath and washing your hair.
One of the "Bath Overture": Wash your face
Why should you put washing your face in the first place? It turns out that when you enter the shower room, when the hot water is turned on, it will produce hot air, and the pores of the human body will expand when heated. Therefore, if you don't wash your face first at this time and accumulate dirt on your face for a day, you will sneak into the pores while the pore door is open.
Over time, your pores will be squeezed bigger and bigger by these dirty things, occupying the territory that should not belong to them, and more and more acne will appear on your face, but don't believe what others say to you, "youthful and beautiful acne."
In addition, don't think that you won't be attacked by dust when you sleep at night, so the number of times you wash your face a day should be: get up once, before lunch break, and before taking a bath at night, three times. Wash your face with warm water when taking a bath, because if you use hot water for a long time, it will promote skin aging, so please wash your face with warm water to keep your skin young.
Bathing Overture Part II: Bathing
When taking a bath, the water temperature can be hot, which can effectively promote metabolism, accelerate blood circulation, expand pores, and completely expel sweat and dirt from the body. Every time the human body excretes 1 kg of sweat, it can take away about 540 calories. Let yourself shower in hot water at 40 degrees Celsius 10 minutes or so, you can consume 200 calories! It's killing two birds with one stone to take a relaxing bath and lose weight happily.
But the time should be controlled within 20 minutes, and good ventilation should be ensured. When taking a bath, close your eyes and try to relax. Let the shower head sway back and forth on the skin, and after bathing, the skin and mind can be fully decompressed.
Bath Overture Part III: Shampoo.
Hair is moistened in steam. At this time, the best time to wash your hair has arrived.
Wet your hair thoroughly with water, then apply shampoo, rub it for a while, rinse it off with clear water, remember to rinse it off, then apply ointment or conditioner evenly, gently massage for three to five minutes, comb it with a wide-toothed comb and wash it off. Finally, rinse the whole body thoroughly with clear water. Since then, the bath trilogy "Beauty in the Bath" has been declared a success.
