1. Precautions for keeping in good health in winter
1. Wear a scarf in winter, and don't cover your mouth
In cold winter, whether you are an old man over 6 years old, a child, a young man or a beautiful girl, wearing a scarf when you go out can not only prevent wind and cold, but also add beautiful elegance. When wearing a scarf, don't cover your neck with your mouth. It seems to keep you warm, but it's not good for your health. Because scarves are mostly made of wool, rabbit hair and blended wool, the fiber is easy to fall off, and because it is easy to absorb dust and germs, and it is not often washed, when the scarf touches people's nose and mouth, the fallen fiber, dust and germs can easily enter the body with breathing, making people susceptible to respiratory diseases.
2. Wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket
In winter, people wear thick clothes, and the heat is mainly lost from exposed parts such as their heads and hands. According to the test, people who don't wear hats at rest lose a lot of heat from their heads. When the ambient temperature is 15℃, the heat lost from the head accounts for 3% of the total heat dissipation of the human body, 6% at 4℃ and 75% at MINUS 15℃. Thus, the warmth of the head is closely related to the heat balance of the human body. As the saying goes: "Wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket."
When wearing a hat in winter, special attention should be paid to the fact that the hat can protect the ears, and children should pay more attention to wearing a hat at any time.
3, 18℃, ideal temperature
In winter, the outside is cold, and the temperature difference between indoor and outdoor is large. Generally, it is more suitable to keep 16℃ ~ 2℃ indoors, and 18℃ is the most ideal.
If the indoor temperature is too high, it will make people feel sultry and upset, making people dizzy and depressed. After a long time, it will also cause dry mouth and dry eyes, which will break the physiological balance of the human body for a long time, cause physiological changes and cause diseases. Especially in the northern winter, when the temperature is too high, it is easy to cause exogenous cold.
If the indoor temperature is too low, it will cause the human body to dissipate heat too quickly, which will greatly consume the human body's heat energy, often making people feel cold and timid. Those who are weak will cause chills, and those who are weak in gastrointestinal tract will cause abdominal distension and gastrointestinal pain.
4, 45% ~ 6% RH, healthy humidity
Indoor humidity should be suitable in winter, and 45% RH ~ 6% RH is called "healthy humidity".
if the indoor humidity is too high, it will be difficult for the human body to dissipate heat. When the indoor temperature is too high, it will be oppressive; When the indoor temperature is low, the humidity is higher than '8%RH, which will make the human body dissipate heat too quickly and increase the cold feeling.
If the indoor humidity is too low and the air is dry, people's respiratory tract will be dry and uncomfortable, which will cause dry mouth and sore throat. Generally, there is little precipitation, strong wind, dry climate and low indoor humidity in winter in northern China. Especially in winter, when the stove is burned and heated, the indoor air is dry. It is often necessary to put a kettle on the stove to let the water in the kettle transpiration, discharge steam indoors, or spray water on the ground to increase the air humidity. In order to better control the air humidity, a humidifier can be selected.
5. Create an ideal "clothing climate"
The so-called "clothing climate" means that the surface temperature of the clothes is about zero degrees Celsius, while the temperature between the inner layer of the clothes and the skin is always kept at 32℃ ~ 33℃. This ideal "clothing climate" can create a good microclimate around the human body, buffer the invasion of the external cold climate on the human body and keep the human body at a constant temperature.
The specific measures to create an ideal "clothing climate" are as follows: the physiological function of the elderly is declining, the skin is aging, the vasoconstriction is weakened, and the metabolic level is low, so it is appropriate to wear light and warm clothes; Young people have strong metabolic ability and relatively sound self-regulation ability. For cold stimulation, skin blood vessels can contract to a greater extent to reduce the loss of body heat. Therefore, clothes should not be too thick; Infants and young children, on the other hand, are immature and have low thermoregulation ability, so we should pay attention to keeping warm, but infants and young children have strong metabolism, and they should not be covered too thick, so as not to sweat too much and affect their health, so clothes should be added and subtracted frequently.
6, the weather is cold, and the feet should be warm
As the saying goes, "cold starts from the feet", the feet are farthest from the heart, and the blood supply is small and slow. In addition, the fat layer under the skin of the feet is thin and the heat preservation is poor. Therefore, the skin temperature of the feet is the lowest, and the toe tip temperature is sometimes only 25 C. Traditional Chinese medicine believes that the cold pathogen in the foot will inevitably affect the internal organs, which can lead to epigastric pain, diarrhea, irregular menstruation, impotence, lumbago and leg pain and other diseases. Cold feet will also reduce the disease resistance, which will lead to upper respiratory tract infection. Therefore, we must pay attention to the health care of our feet in the cold winter.
In winter, the size of shoes and socks should be slightly larger, and there should be a gap between feet and shoes, that is, using the heat insulation of air to enhance warmth. The sole should be properly thick, because the thick sole makes the shoes have good cold-proof performance. People who work in ice and snow should wear hairy high-waisted leather shoes or long boots. People who often have frostbite should wear cotton shoes as soon as possible; People with sweaty feet should choose cotton shoes and cotton socks with good permeability. When the socks and insoles are sweaty, they should be dried in time, and the cotton shoes should also be dried frequently.
2. Ways of keeping in good health in winter
1. Eat less raw and cold food
If you eat raw or cold food in winter, it is easy to cause various gastrointestinal diseases. Therefore, in order to be healthy, we must pay special attention to the warm work of the body and stomach in winter, and eat less cold food, especially some people who are weak and in poor health. In addition, if you want to warm your stomach, you can add some pepper or ginger to your daily diet, which can warm your stomach and protect your spleen and stomach.
2. Don't overeat in daily life
The key to nourishing the stomach is to eat fully and don't overeat. If you eat too much food at one time, it will increase the burden of gastrointestinal digestion and lead to food accumulation and flatulence. Therefore, we should eat more foods that are easy to digest, non-irritating and healthy for the spleen and stomach. In addition, you can drink more porridge in the morning and evening, which is not only nutritious, but also easier to digest and less gastrointestinal burden.
3. Keep a good mood every day
Do you know that a good mood can not only broaden your mind, but also have a great impact on your health, and it also has the effect of nourishing your stomach? Many modern people have gastrointestinal diseases, which are mainly caused by the pressure of work and life, and the quality of sleep is not good, which often keeps them in a tight state for a long time, which leads to the normal operation of the stomach being affected. Therefore, if you want to better regulate the stomach and intestines in winter, you must maintain a good mood, which will make the gastrointestinal tract run more smoothly.
4. Quit smoking alcohol, strong tea and coffee
In addition to the above, you need to say no to alcohol, tobacco, strong tea and coffee in winter, so that you can be healthier. Through research, it is found that long-term smoking can easily lead to peptic ulcer in the stomach, while drinking can lead to gastric bleeding and so on. Drinking strong tea and coffee for a long time is also very harmful to the gastric mucosa. Therefore, for the sake of health, we must say NO to these drinks and cigarettes.
In fact, there are a lot of knowledge about health care in winter, but we only need to master the basics and start health care from the aspects of food, clothing, housing and transportation, and then our health will naturally get better and better. In addition, winter is also the best time to nourish the stomach, so be sure to eat more warm and digestible food to keep a good mood.
