Read popular science and understand life
The Spring Festival holiday is over, the children's winter vacation is nearing the end, and many people want to say goodbye to their hometown and go far away. It is another year of great migration from the north to the south, the climate difference between the north and the south is large, the age is poorly adapted, and you want to drive away the discomfort associated with "migration"?
There is a way!
First heavy to keep warm
How do "migratory birds" dress and keep warm in the north and south? If you are traveling from the north to the south, it is not advisable to wear too much, otherwise it is easy to sweat and it is easier to catch a cold after blowing. It is recommended to prepare coats and accessories that are easy to put on and take off, and reduce clothing in time after arriving at warm destinations in the south.
If you are traveling from the south to the north, dress lightly and warmly. Carry a thicker down jacket with you, which comes in handy if the climate at your destination is colder than you might think. Second, remember to wear a scarf, hat, woolen gloves, cotton socks and warm boots. In a word, pay attention to the weather forecast before departure, and increase or decrease clothing in time.
Every winter, heating begins in the northern part of the continent, while people in the southern region joke that they can only "stomp their feet to keep warm." Although heating is an essential warm facility for the north home, the doors and windows are tightly closed, the indoor air circulation is not good, the room temperature is high and dry, which is conducive to the spread of bacteria, easy to make people irritable, nasopharyngeal dryness, dizziness, weakness and so on, these symptoms are called "heating disease".
Preventing heating diseases and controlling temperature and humidity are key. Usually, the room temperature is 18 ° C ~ 24 ° C, the humidity is 50% ~ 60%, and the human body feels the most comfortable. Remember to open more windows for ventilation, it is best to open the window once in the morning and evening, and the ventilation time is not less than half an hour each time. You can also use a humidifier or place a basin of water in front of the bed. Then it is appropriate to adhere to outdoor exercise, and to pay special attention to keeping warm when going outdoors.
Wet and cold is hard to boil
Compared with the north, the winter temperature in the south is not so low, but the wet and cold are also difficult to endure. Air conditioning, electric blankets, hot water bottles and warm baby can all come in handy. But sometimes with these heating artifacts, the body will "inexplicably" grow blisters. This is actually a low temperature burn! Hereby remind everyone that the elderly suffering from diabetes, vasculitis, stroke sequelae and long-term bed rest should not be exposed to items with a temperature exceeding body temperature for a long time. If you use an electric blanket, do not set the temperature too high; when using a hot water bottle for heating, first wrap the hot water bottle with a towel.
In the southern regions of Sanya, Guangxi, Beihai, Guangdong, etc., the winter climate is humid and warm, which is suitable for some people with stable chronic diseases, such as the elderly with cardiovascular and cerebrovascular diseases, chronic bronchitis, asthma and other diseases. Of course, the South is good but not for everyone. According to reports, the humidity in some southern cities is more than 60%, and the elderly who spend the winter in the south mean that they also face the challenge of moisture, which may induce rheumatism.
The problem of heavy moisture can also be solved from two aspects. From the internal point of view, the elderly can soak their feet, exercise and other ways to remove sweat, accelerate the discharge of moisture out of the body, and can also be assisted by eating porridge, tea, soup and other dietary therapy methods. From the outside, it is best to have a hygrometer at home, monitor the humidity in the room at any time, and you can also use dehumidifiers, air conditioners, etc. for dehumidification. Remind the elderly suffering from gout and rheumatism that tropical and subtropical humidity should not be suitable for long-term residence.
Dietary advice
There are obvious differences in eating habits between the north and the south.
Start by saying "drink". The north is colder, and the tea drinking is mainly black tea and flower tea. A cup of hot tea can also drive away the cold and promote digestion. Southerners prefer green tea and like the clear fragrance of green tea, but the sex is slightly cold.
Let's talk about "food". The southern taste is light, the northern taste is thick, and the "southern sweet and northern salty" is "sweet and salty". In terms of staple food, the south eats more rice and the north eats more noodles. The choice of ingredients in the north and south is different, and the fat content and salt intake are different. Southerners are more refined and light; northerners prefer to eat large stews and other flavors. Then, in the case of this north-south difference, people with weak spleen and stomach function may have symptoms such as abdominal pain, diarrhea or constipation.
Next is the specific advice: the weather in the north is cold, you can eat spicy food, beef and mutton, etc., to keep warm and warm. Patients with underlying diseases such as hypertension and coronary heart disease should avoid excessive salt intake in the northern region, resulting in water and sodium retention and aggravating hypertension and heart disease. The southern region has a sweet taste, and there are more high-sugar fruits in the tropics, so patients with diabetes should avoid consuming too much sugar. In addition, if you go to an area rich in seafood, you must be careful of gout when you welcome "seafood + beer".
In short, although it is necessary to follow the customs of the countryside, it is even more necessary to scientifically adjust the diet structure, achieve nutritional balance, and consume meat, eggs and milk every day according to personal circumstances. Try not to drink refreshing drinks such as coffee and strong tea. You can exercise appropriately, keep your mind at peace, and ensure sleep.
Extra attention
01
The northern winter climate for the elderly and children is dry and sometimes smog, which may lead to the recurrence and aggravation of chronic respiratory diseases. In a low temperature environment, peripheral blood vessels will constrict, resulting in increased blood pressure, and the incidence of coronary heart disease, angina and myocardial infarction will increase. The cold will also make the blood circulation of bones and joints poor, resulting in joint pain, synovitis and other symptoms of osteoarticular diseases aggravated. Therefore, please pay attention to the main forces in the great migration of the north and south - the elderly and children, prepare commonly used drugs, and pay attention to daily routines.
02
Fractures and snow blindness Recently, heavy snow has fallen in the south of the continent, and the Winter Olympics have also made ice and snow sports fire. Skiing, sleigh rides, building snowmen, and snowball fights are all popular winter tours. However, slippery and slippery snow is easy to fall, especially in the elderly, and once they fall, it is easy to fracture. In addition, the ultraviolet rays in the sunlight are reflected through the snow to the cornea of the human eye, which is easy to cause snow blindness. It is recommended that when you go out, change into flat shoes with rough soles and stripes as much as possible, with a small stride as possible, slow and maintain a fixed pace, pay attention to body balance; do not stay in the snow for too long, it is best to wear sunglasses, masks and other protective equipment.
03
Although frostbite is a small problem, it is not a small problem, but it is not a small problem. To prevent frostbite, it is necessary to promote blood circulation. Rubbing hands and stomping feet can promote telangiectasia and accelerate peripheral microvascular circulation. People who work in the cold and are exposed to cold water should be active and avoid sitting or standing for a long time. Second, soak your hands and feet with warm water. When returning from the outdoors, do not immediately roast the fire for warmth, and should slowly move your hands and feet before heating up. Third, we must pay attention to the cleanliness of hands and feet, and the breeding of bacteria is also an important cause of frostbite. Fourth, pay attention to keep warm and keep dry. Especially people with sweaty hands and feet. Fifth, it is necessary to strengthen exercise and improve the cold tolerance of the body.
