the summer has just passed, and the weather has not been cool for a few days, & ldquo; Autumn Tiger & rdquo; It came again, and sweating became a disturbing thing. Although & ldquo; It’s better to invite people to sweat than to invite people to dinner;, It shows that more and more people realize the benefits of sweating, but it is also sweating. Some people will harm their health, while others will & ldquo; Health Sweat & rdquo;.
can you see health from sweat?
the human body has 2-2.5 million sweat glands, which are connected for 20-30 kilometers, except that there are no sweat glands in very few parts such as lips. Hot sweat is discharged from the chest, neck and back, while cold sweat is discharged from the palms, soles of feet and armpits. Sweat glands in these parts of the human body are developed, with an average of 400 ~ 600 sweat pores per square centimeter. According to the experimental measurement, every 1 kg of sweat can reduce the body temperature by about 15 ℃.
sweat is mainly composed of water and salt. 1.53 g of salt is contained in 1 kg of sweat, so sweat is salty. People who sweat too much lose not only water but also salt. When people sweat a lot, they should not only drink white water, but also add an appropriate amount of salt to their drinking water, or eat more salty food to meet the human body’s needs for water and salt; Break even & rdquo;.
research shows that the strength of human tolerance to heat is related to the number of heat stress proteins in cells in vivo. People who often insist on exercise have significantly increased heat stress protein synthesis, enhanced heat tolerance and can resist the invasion of high temperature heat wave. People who like to enjoy air conditioning have reduced heat stress protein synthesis and their tolerance to high temperature. Once they leave the air conditioning and come to the environment with billowing heat waves, they are difficult to adapt. Sweat glands & ldquo; Air conditioning unit & rdquo; It will also fail to start because it is not used for a long time, sweat cannot come out, heat cannot be dissipated, and heatstroke is very easy to occur.
link: normal people excrete about 500 ~ 1000 ml of sweat every day, up to 1500 ~ 2000 ml in summer. If the sweat glands stop sweating or sweat too much, it is an abnormal phenomenon. From the perspective of traditional Chinese medicine, sweat is the metabolic product of body fluid. It is called five fluids together with runny nose, tears, saliva and saliva. In addition, sweat is also known as the heart fluid “Su Wen Xuan Ming five Qi”, and the heart controls blood, so there is a saying that sweat and blood are of the same origin. Sweating too much will consume Qi and hurt body fluid and blood.
under the scorching sun, sweating in the sauna room and sweating on the playground, what kind of sweating method is correct?
modern people sweat too passively
there are two ways of sweating: active sweating and passive sweating. When waiting for the bus after work, the clothes were soaked by the sun; Bothered by work pressure, irritable and anxious, sweat trickling slightly from his forehead; Steam sauna with friends and sweat in the muggy Environment & hellip& hellip; Zhu Xuejun, a professor of dermatology at the first hospital of Peking University, said that most of these sweating methods are very passive. In general, sweating caused by weather, environment or psychological pressure is called passive sweating. Only sweating caused by exercise is active sweating. The survey shows that the proportion of people who can exercise regularly accounts for only 28.2% in both urban and rural areas. This shows that the main way of sweating of modern people is passive sweating.
there are also dynamic sweating and static sweating in traditional Chinese medicine. Fu jieying, a health care expert and professor of Guangzhou University of traditional Chinese medicine, told the life times that sweating caused by weather and environment belongs to static sweating, which is equivalent to passive sweating. Many abnormal static sweating need attention, such as spontaneous sweating, night sweating, etc. Some people sweat on their front and back when they are not hot or exercise, and are prone to fatigue, cold and panic, especially afraid of the wind and cold. This is called self sweating, which is a manifestation of qi deficiency. Sweating as soon as you fall asleep at night is called night sweat, which is a manifestation of yin deficiency. Different sweating parts can reflect a person’s physical condition. Excessive sweating on the forehead and face is a manifestation of stagnation and excessive internal heat. It is easy to be irritable, bitter mouth and yellow urine; Sweating on the front and back of the heart is heart qi deficiency, easy to palpitation, panic, insomnia, dreaminess, trance and forgetfulness. In addition, there are some ways of sweating, which belong to the symptoms before the onset of the disease. For example, some old people sweat half of their body and have no sweat half of their body. At this time, we must be careful of stroke.
there is also great attention to the smell and color of sweat. If the smell of sweat is fishy, it may be related to heat syndrome or damp heat syndrome, which generally belongs to liver heat. It may be caused by bacteria in the armpit. If iodine is found in the armpit, it may also be caused by light sweat.
Chinese and Western medicine to distinguish diseases from sweating
1. Amount of sweating
● no sweating: is also called closed sweating, which means that the sweat glands are reduced or the body does not produce sweat, and there is little or no sweating locally or throughout the body. The skin of some parts or the whole body of patients is very dry. Most of them have suffered from skin diseases (such as psoriasis, scleroderma, etc.), which block their pores and make them sweat free. In addition, if the body’s metabolism is disordered, there may be no sweat.
● hyperhidrosis: hyperhidrosis refers to massive sweating under constant temperature and static conditions. If sweating is accompanied by palpitations, hyperappetence, mood swings and insomnia, it may be hyperthyroidism. If you are sweating, dizzy, weak and hungry, it may be hypoglycemia and poor liver function. Hyperhidrosis can also occur after taking some drugs. If you sweat like beads and cold sweat continues, you must pay attention. This is the manifestation of Qi dispersing deficiency, which is called & ldquo; No sweat & rdquo;, It’s a sign of critical illness.
2. Sweating time
● self sweating: in the daytime, in a state of soberness, sweating is not due to labor, wearing thick clothes or high temperature. Traditional Chinese medicine believes that this is the manifestation of qi deficiency and yang deficiency. The body perspires unconsciously due to the loss of solid absorption. People who sweat themselves are usually depressed, short of breath and afraid of the cold.
● night sweat : it refers to sweating in the chest, back, thighs and other places at midnight or dawn after falling asleep. There is a lot of sweat, which can make clothes wet. No sweat after waking up. Night sweats are mostly caused by Yin deficiency. If they are accompanied by symptoms such as low fever, flushing on both cheekbones, fever in the palm of the hand and dry mouth, they may be signs of lung disease, such as tuberculosis.
3. Sweating site
● head sweating: mostly sweating on the head and face, which is caused by heat in the liver and stomach and Qi deficiency. If both limbs are cold and short of breath, it is mostly Yang Qi deficiency. If there is sudden sweating on one side of the forehead, the cervical sympathetic nerve is stimulated and may suffer from aneurysms.
● sweating of hands and feet: when you are nervous, your hands and feet will sweat. Otherwise, your hands are often wet and cold, mostly due to damp heat of the spleen and stomach, Qi deficiency and kidney deficiency.
4. The color of sweat
the sweat of ordinary people is colorless or slightly yellowish, which is the sweat color of normal people. People with different diseases have different sweat color, which is just like an indicator of symptoms. If a person takes potassium chloride, his sweat will turn red. If you eat too much egg yolk and carrots, your sweat will be dark yellow.
link: sweating when eating
this situation is called & ldquo; Dietary hyperhidrosis & rdquo;. It is mainly manifested in a lot of sweating every time you eat, especially when you eat hot food or irritating food. It is generally limited to the lips, forehead, cheeks, nose, chin and other parts. In severe cases, there can also be a lot of sweating on the chest and back.
after eating stopped, sweating gradually decreased to stop. Dietary hyperhidrosis can be divided into primary and secondary. Most of the primary diseases start from childhood. The main reason is the imbalance of the central nervous system, which makes the sweat gland secretory fibers of the autonomic nervous system over excited. Secondary diseases are more common in patients with peripheral neuropathy, such as peripheral nerve injury. The above symptoms generally do not need treatment and there is no effective treatment. Patients with severe condition can be operated by parasympathetic nerve blocking.
hyperhidrosis may be the precursor of disease
hypoglycemia: hypoglycemia can be caused by many reasons, which can be mainly manifested by the symptoms of sympathetic hyperexcitability. During the attack, the sudden drop of blood glucose stimulates sympathetic excitation and releases a large amount of suprarenal glandular hormone, which can lead to a large amount of cold sweat.
hyperthyroidism: hyperthyroidism. Fear of heat and sweating is one of the characteristics of this disease, and it also shows symptoms such as mental tension, personality change, irritability, inability to concentrate, difficulty in falling asleep and so on.
pheochromocytoma: its common symptom is sweating. Sweating is paroxysmal and sometimes persistent, but flushing or whitening of the face can occur at the same time. There will also be panic, shaking hands, cold limbs, etc. However, the attack of this disease is often accompanied by significant increase in blood pressure and headache.
active sweating is good for health.
is also sweating. When the weather is hot, passive sweating can still make people sweat. Why is it better than active sweating? Experts explained that no matter the sweat from the heat or the sweat from the sauna, it is only sweating on the shallow surface of the human body, and exercise is the real deep layer sweating, that is, it makes people sweat from the inside to the outside. This kind of sweat is the self-regulation of the human body. After sweating, people not only feel very comfortable, but also play the following 8 roles.
discharge toxins. Professor Shen Yanying, vice president of Beijing Chaoyang Hospital Affiliated to Capital Medical University, said that active sweating can accelerate the body fluid circulation and metabolic process of the human body, discharge the accumulated lactic acid, urea, ammonia and other toxins in the body, and ensure the smooth flow of the system of nose, skin, lung and large intestine.
control blood pressure. hypertension is a phenomenon that occurs due to the narrowing and hardening of the inner diameter of blood vessels and the restriction of unit blood flow. Exercise sweating can expand capillaries, accelerate blood circulation, increase the elasticity of blood vessel wall and reduce blood pressure.
promotes digestion. not sweating and slow running of Qi and blood will affect digestion and lead to people’s lack of flavor; People will not sleep at night, which will also affect their nerves.
anti osteoporosis. many people think that sweating will lead to the loss of calcium in the body with sweat. In this regard, Zhang Yatong, a clinical pharmacist of the pharmacy department of Beijing Hospital of the Ministry of health, pointed out that only water-soluble vitamins will be lost with sweat. Although calcium is soluble in water, its solubility is very low and is unlikely to be discharged with sweat. On the contrary, sweating is conducive to the effective retention of calcium and the prevention of osteoporosis.
enhance memory. a long-term education experiment conducted by the United States for 20000 middle school students shows that active sports sweating will have a positive effect on students, and their memory and concentration can be greatly improved.
skin care and beauty. people who always don’t sweat have slow skin metabolism and some wastes are difficult to discharge. Sweating can clean pores and achieve the effect of beauty and skin care.
lose weight . When the human body moves and reaches a certain intensity, fat will burn and convert into heat, which will be discharged from the body through sweat. two thousand two hundred and twenty-three
