The health care function of hot water bath is to promote blood circulation, eliminate fatigue and make people feel comfortable. However, the whole body hot bath or shower will make people's blood pressure rise and their heart beat faster. Therefore, patients with hypertension and heart disease should try to avoid or use hot bath with caution to prevent accidents. Hot water bath should not be soaked for a long time. When the water temperature is 42℃, it should be soaked within 10 ~ 15 minutes. When the water temperature is above 45℃, the soaking time should be controlled within 5 ~ 10 minutes.
Soak your feet with only about 60% hot water every night 10 ~ 20 minutes, and the water depth is slightly higher than the ankle. Modern medicine believes that soaking feet with hot water can reflexively improve the whole body blood circulation, make the whole body qi and blood smooth, and have a certain effect on eliminating fatigue, improving sleep, preventing insomnia and enhancing immunity. Soaking feet with hot water can also stimulate nerve endings, relieve brain congestion, relieve headaches and rhinitis, which is of great benefit to patients with hypertension, arteriosclerosis and cardiovascular diseases.
Soaking your hands in hot water can cure migraine. Immersing hands in hot water that can be tolerated by hands for 20 ~ 30 minutes can treat migraine. The reason is that migraine is usually caused by cerebral vascular congestion and expansion and cranial nerve compression. Soaking hands with hot water can gather blood in hands and reduce cerebral blood flow, which can relieve cerebral vasodilation, relieve the oppression on cranial nerves, and relieve or eliminate migraine. Furthermore, hot water can stimulate nerve endings in the hands, just like acupuncture in traditional Chinese medicine, and can also treat migraine.
Fumigating the nose with hot water can prevent and treat colds. The virus is cold-resistant and heat-resistant. Usually it can kill the virus at 60℃ for 30 minutes. When you catch a cold or catch a cold, cover the mouth of the cup with the water boiled in Sheng Gang (be careful not to burn it), inhale the steam of hot water through the nasal cavity, and then change it after cooling, several times a day. In this way, the temperature in the nasal cavity rises, and it is difficult for influenza virus to survive in the nasal cavity. Moreover, lysosomes in cells can easily release proteolytic enzymes, which will also inactivate influenza viruses.
2. Micro-warm water bath The water temperature of the micro-warm water bath is between 25-34℃. In addition, the micro-warm water bath is a kind of health care micro-warm water bath, which means that the water temperature is slightly higher than the body temperature, and the required water temperature is between 36-39℃.
Soaking in warm water for 20 ~ 30 minutes in a relaxed and happy mood has the functions of promoting blood circulation and relieving pain, eliminating fatigue and tension, resting nerves and stimulating appetite. Mild warm water bath has little effect on heart and blood pressure, so patients with heart disease and hypertension are prone to mild warm water bath.
3. Alternating method of cold and hot water As the name implies, alternating method of cold and hot water is a kind of health training of alternating exercise of cold and hot water. The method is to massage and pat the back with hands or fitness equipment, and then the chest and abdomen reach the legs, arms, feet, hands, head and face to warm up the body. Then rinse the whole body with a hot shower for three or four minutes, so that the whole body skin, especially the back skin, becomes slightly reddish. Followed by a few seconds of cold shower. Then take a bath under hot water for three or four minutes, enjoy the comfort of hot water bath, and then accept the instant cold water bath. After two or three hot and cold showers, shake off the water droplets on your body, dry your whole body, get dressed and exercise your whole body immediately.
It is best to alternate hot and cold water after getting up in the morning. The most suitable crowd is healthy teenagers or healthy middle-aged and elderly people. Patients with diseases should obtain the consent of doctors or be carried out under the guidance of experienced medical staff, and must not be carried out casually.
Alternating hot and cold water health care method is a health care training method with heat regulation and environmental adaptation. The significance of training lies in activating various functions of the body, accelerating blood circulation, promoting the body's adaptation to climate change, thus improving the body's immune function and awakening the body's own disease-resistant potential. This health care method of alternating cold and heat plays a special role in strengthening physical fitness and preventing colds, influenza and some virus infections. 6. Indoor environmental health care 1. Daylighting and sunshine in the bedroom are one of the indispensable conditions for human survival. If the lighting is unreasonable and the light is insufficient, people's eyesight will be tired, which will lead to discomfort and fatigue of the whole body. Therefore, the choice of bedroom should be as sunny as possible.
The intensity of light is usually expressed in lux. According to the requirements of living room health care, the natural light illumination of living room is 50 ~ 100 lux. If the window lighting area and indoor building area are kept at1/8 ~110, the lighting requirements of the living room can usually be met.
Do a good job of indoor lighting, not only by windows, but also by the whiteness of walls and ceilings, because white ceilings and white walls can reflect light and improve indoor brightness. Therefore, the reflective effect of the room must be considered when decorating the room.
2. The temperature in the living room has a great relationship with health. Under the condition of normal temperature and airflow, the suitable temperature in summer is between 2 1 ~ 32℃, and 24 ~ 26℃ is the most ideal temperature. The suitable room temperature in winter is 16 ~ 20℃, and 16 ~ 18℃ is the most ideal temperature. However, because people live in different climatic zones, their adaptability to room temperature changes is also different. For example, people living in tropical areas are more resistant to heat, while people living in cold areas are more resistant to cold. Of course, this adaptability is limited. For health, the room temperature is 15 ~ 30℃.
3. The living room humidity has a great influence on health. When the air humidity is lower than 30%, a large amount of water in the upper respiratory mucosa will be lost, which will make people feel uncomfortable with dry throat and reduce the defense function of the respiratory tract. When the air humidity reaches above 80%, it will make people feel dizzy and sultry. Especially in high temperature and high humidity, the evaporation and heat dissipation of human body are blocked, which will make people suffer from heatstroke for a long time; When the temperature is low and the humidity is high, people will feel extremely cold.
Therefore, under the suitable room temperature in winter, the indoor humidity should be 30% ~ 40%; In summer, the suitable indoor humidity should be controlled within the range of 30% ~ 70% under suitable room temperature conditions.
4. Ventilation in the living room. Window ventilation can discharge various harmful gases such as carbon dioxide, carbon monoxide, sulfur dioxide and various microorganisms and germs in the room, thus supplementing fresh air. Ventilation by opening windows is one of the important measures to improve indoor hygiene and prevent diseases. The time of indoor ventilation can be properly controlled according to the indoor temperature, and usually it should not be less than 30 minutes. It is wise to open the window in the morning and at night. Opening the window in the morning can eliminate the turbidity at night; Opening the window a little before going to bed at night can let in fresh air and make people sleep soundly.
Window ventilation can not only make the air circulate, adjust the indoor temperature, but more importantly, make people closer to nature. Because if people's immune defense system is in a constant temperature state for a long time, it will become numb and dull, and it is difficult to cope with sudden temperature changes. If the room is often ventilated, it will strengthen the human immune system, make it adapt to the outside world, and will not induce diseases due to sudden climate change.
Nowadays, advanced temperature control equipment such as air conditioner enters the home because after installing air conditioner, the indoor and outdoor air circulation channels must be closed, forming an indoor "microclimate". If people stay in such an environment for a long time, they will be uncomfortable outdoors, and even cause colds or heatstroke. In addition, indoor natural air will lose a lot of negative ions after repeated filtration by air conditioning system, which may lead to physiological imbalance of human body and symptoms of blood circulation disorder such as dizziness and headache. Secondly, the condensate tank in the air conditioner provides suitable temperature and humidity for the growth of microorganisms such as mold, which can lead to bronchitis, bronchitis and other respiratory diseases. If people live in air-conditioned rooms polluted by bacteria for a long time, they are likely to suffer from "air-conditioned pneumonia". Therefore, residents with air conditioning at home should have ventilation or outdoor exercise.
5. Indoor decoration should prevent chemical pollution. Nowadays, home interior decoration is becoming more and more exquisite, but its pollution problem is becoming increasingly prominent. Research shows that building decoration materials, including various paints, coatings, plastics and various adhesives, volatilize more than 500 kinds of toxic gases. For example, the paint sprayed on the wall often contains harmful substances such as toluene, xylene and formaldehyde; Asbestos is often mixed in gypsum used for ceiling decoration, and asbestos dust is one of the important pollutants that cause lung cancer. Decorative materials such as plywood, floor leather, plastic veneer and wallpaper all contain formaldehyde and some organic solvents, which can volatilize toxic chemicals; Paint contains lead compounds, plastic shutters, etc. Containing formaldehyde, its smell will stimulate various systems of the human body and may cause various diseases; Some building materials also contain radioactive substances, which will do harm to human health. So when decorating the living room, you must choose low-toxic or non-toxic materials. After the room is decorated, you should open the window for a while before moving in.
6. The room should be quiet. The unit of noise level is called decibel. When the noise is below 30 decibels, the environment is quiet, and when the noise is 50-60 decibels, the environment is noisy. The sound in daily life is generally around 40 decibels.
Excessive noise is a public hazard, which will disturb the balance of excitement and inhibition in human cerebral cortex, affect physiological function and damage health. Living in a noisy environment for a long time will make people feel tired, uneasy, nervous, sleep badly and even lead to neurasthenia. Therefore, the family room must stay away from noise and try to avoid unnecessary noise in family life. 7. Go outdoors often. Some physiologists have proved that staying indoors for a long time in modern buildings will cut off the stimulating effect of atmospheric electric field changes on human body, and people's immune function will decline, and they will also fall into drowsiness and boredom. When the atmospheric electric field (weather conditions) changes strongly, people will have various diseases because they don't adapt to the changes. Therefore, people living in modern buildings must often go outdoors to adapt to the strong changes of weather (atmospheric electric field).
