Every winter, some people will feel poor breathing, the number of colds will increase, and even symptoms such as drowsiness, unresponsiveness, fatigue, listlessness, chest tightness, shortness of breath, headache, etc. This is related to people's reaction to the outside world when the seasons change, but another important inducement is the lack of oxygen supply in winter.
When the temperature is low in winter, people stay in a closed space for a long time. Because of being afraid of cold and not paying attention to ventilation, the indoor air can not be replenished and replaced in time, and the air quality drops. In addition, when people's outdoor activities are reduced in winter, there will be physical hypoxia, which meteorologists call "hypoxia syndrome". If hypoxia lasts too long, a series of discomforts will appear, even life-threatening in severe cases.
According to the detection of relevant state departments, the oxygen concentration is about 2 1% in places with good oxygen. After sleeping in a closed bedroom for one night, the oxygen concentration will drop to about 17%, or even lower. It is the easiest way to prevent "hypoxia syndrome" by opening windows frequently in winter. Therefore, in winter, proper ventilation is necessary, which is beneficial to people's physical and mental health and avoids "hypoxia syndrome".
Second, take a bath and pay attention to the water temperature to prevent dry skin.
Skin is a very sensitive organ. In winter, the blood vessels of the skin often contract, and the secretion of sweat glands and sebaceous glands is obviously reduced. Some people will have itchy skin, redness and swelling, and even irregular chapping and peeling, especially in the lower limbs. Among them, it has something to do with the way you take a shower. Some people are afraid of not being cleaned, and they are used to rubbing it repeatedly with shower gel and hot water like summer, and the oil on the skin surface is washed repeatedly, and the dry skin is getting more and more serious. There are also some skin diseases that occur frequently in autumn and winter, such as psoriasis, atopic dermatitis and ichthyosis. And the condition will be aggravated or aggravated by dry skin.
Countermeasures: In winter, if you love cleaning, you should pay more attention to the composition and frequency of bathing. Don't bathe too often, and the water temperature should not be too high. Try to use a bath containing moisturizing ingredients.
Pay attention to the following 7 points before and after bathing in winter:
1, drinking a cup of hot water before taking a bath can supplement the water loss caused by telangiectasia.
2. Applying body lotion after bathing can lock the moisture on the skin surface and relieve dryness and itching.
3. Dry the whole body with a dry towel after bathing, and put on clothes, shoes and hats as soon as possible to prevent colds.
4, the bathing force should not be too large, which will damage the squamous epithelial cells of the skin and reduce the natural protective function of the skin.
5, usually pay attention to drink plenty of water, eat more fruits and vegetables to provide enough water for the skin, sebum is definitely the best protection for the skin.
6. In dry areas, you can rub some urea grease or vaseline every day. Usually, you should also eat more fresh vegetables and fruits rich in vitamin B and vitamin C.
7. It is not advisable to 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.
Third, static electricity is harmful and should be "prevented" and "discharged".
In dry winter, people often encounter this situation: when combing their hair in the morning, their hair tends to "float" and become more and more messy; When you meet and shake hands, as soon as your fingers touch each other, you will suddenly feel a sharp pain in your fingertips. When you pull the door handle and turn on the faucet, you will get an electric shock and make a "bang, bang" sound ... Many people know that this is static electricity, but it is not serious. Experts remind that static electricity is not only painful at that time as many people think. If it accumulates too much, it will bring many adverse effects to human health.
Because the electrification time of friction is very short, the generated current is very small, so static electricity generally does not cause life-threatening to human body, but static electricity will have many adverse effects on human health: it will stimulate human skin, reduce skin moisture, increase dander, and cause skin dryness and itching. Electrostatic accumulation will change the normal potential difference on the surface of human body, affect the physiological process and normal conduction of various organs, especially the heart, and cause ventricular premature beats and arrhythmia.
The skin of the elderly is relatively drier than that of the young, and the aging of the cardiovascular system and the weakening of the anti-interference ability of the elderly make the elderly more susceptible to static electricity. For the elderly with various diseases, static electricity will aggravate the condition or induce arrhythmia such as ventricular premature beats.
For children, if too much static electricity accumulates in children's bodies, it will easily cause abnormal current conduction in brain nerve cell membranes, affect the physiological balance between the central nervous system and the body, and make children feel uncomfortable. In addition, static electricity will absorb all kinds of dust and bacteria, making children's skin delicate and prone to erythema, redness, itching, skin inflammation and pigmentation. Sudden electric shock pain will make children feel frightened, and may also make children move abnormally, increasing the accident rate. Dealing with static electricity, one is prevention, the other is discharge.
In order to prevent the occurrence of static electricity, we should keep a certain humidity indoors, often mop the floor, often sprinkle water, or humidify with a humidifier. Try to wear less chemical fiber clothes in autumn and winter. Underwear, quilt cover, bed sheet, etc. It must be pure cotton or silk. If the coat fabric is chemical fiber, it can be washed with antistatic detergent. At the same time, it is necessary to take a bath and change clothes frequently to eliminate the static charge accumulated on the human body surface. You'd better comb your hair with a wooden comb. When you find that your hair can't be combed, soak the comb in water for a while, and then comb your hair after the static electricity is eliminated.
White-collar workers who often operate computers or those who have been "surrounded" by household appliances for a long time should drink plenty of water and wash their faces frequently, so as to keep the humidity of the office environment, avoid the electrostatic hazard caused by the electric field of computer screens or household appliances, and prevent the skin from being stimulated for a long time to form "computer spots" on their faces. Household appliances should be scattered and unplugged when not in use. Try not to put household appliances in the children's bedroom or less to avoid the electric field and static electricity generated when the human body is in close contact with the appliances.
In winter, many people are afraid to open the door, because their hands will "bang" when they touch the door handle. In fact, before touching the door handle or faucet, you can touch the wall with your hand to "discharge" the static electricity in your body, so that static electricity will not hurt yourself. In addition, barefoot activities on the ground can also release accumulated static electricity.
Fourth, soaking feet in winter is stressful.
In winter, people are chanting more and more, and the sales of various foot massagers on the market are booming. Experts point out that soaking feet with hot water can really relax meridians and warm the whole body, but soaking feet for too long is harmful.
Soaking feet with hot water is good for your health, especially in winter. There is a saying in Chinese medicine that "cold comes from the feet". When the weather is cold in winter, the human body is more prone to various discomforts caused by low temperature, such as blood stasis, cold muscle soreness, cold hands and feet caused by poor circulation of nerve endings, and cold stomachache.
Insisting on soaking feet with hot water can promote blood circulation, dredge meridians, relieve exterior cold, relieve cold hands and feet, dilate capillaries and promote blood supply to the brain. Yin Zhichao suggested that you can add ginger slices, peppers and other accessories to hot water, which has a good effect on dispelling wind and cold.
Hot water soaking feet is not suitable for everyone. Yin Zhichao pointed out that soaking feet in hot water is also taboo. For example, people with beriberi should not soak their feet with hot water if their condition is serious enough to blister, because it is easy to cause wound infection.
Some people like to soak their feet for hours with an electric foot bath. Generally speaking, it is better to soak your feet for 20 minutes before going to bed every day, preferably not more than half an hour. Especially for the elderly, if they soak their feet for too long, they will have symptoms such as sweating and palpitation. Pregnant women should not soak their feet in hot water for a long time.
In addition, some foot baths have slogans such as "can cure all diseases", "bodybuilding" and "suitable for all ages", which are effective for all kinds of disc herniation.
Yin Zhichao pointed out that foot bath is mainly locked in the scope of health care and has no therapeutic effect. In addition, many people directly switch to the massage function when using the foot massager. Experts pointed out that before doing foot massage, you must soak your feet with hot water first, which can speed up blood circulation, relax muscles and ligaments and avoid injuries during massage.
