Old people in Northeast China fly to Sanya by wheelchair group in winter, and take them to Sanya for wheelchair travel.

With the improvement of people's living standards, more and more people put forward higher requirements for their quality of life. Many elderly people living in the northeast are particularly obvious. They are no longer confined to their cold hometown "cats in winter", but fly to the warm south for the winter, and then return to their hometown when bloom is warm in spring. They are called "old migratory birds". According to statistics, there are more than 400,000 "old migratory birds" who choose to spend the winter in Sanya every year, among them, Northeasters are the main ones, accounting for about 80% of the total. The drop in temperature, coupled with the dry climate and smog in winter, makes the human respiratory tract the most vulnerable. In addition, the immunity of the elderly declines, and viruses and bacteria will take advantage of it, leading to the recurrence and aggravation of chronic respiratory diseases. This is one of the normal compensatory reactions of human body. Patients with osteoarthritis often have more serious symptoms in winter.

Let's take a look at what it's like for the elderly in Northeast China to fly to Sanya for the winter in wheelchairs.

With the improvement of people's living standards, more and more people put forward higher requirements for their quality of life. Many elderly people living in the northeast are particularly obvious. They are no longer confined to their cold hometown "cats in winter", but fly to the warm south for the winter, and then return to their hometown when bloom is warm in spring. They are called "old migratory birds".

According to statistics, there are more than 400,000 "old migratory birds" who choose to spend the winter in Sanya every year, among them, Northeasters are the main ones, accounting for about 80% of the total. Their choice is based on science.

The cold environment affects all organs of the human body.

first

A cold has the greatest impact on the respiratory tract.

The drop in temperature, coupled with the dry climate and smog in winter, makes the human respiratory tract the most vulnerable. Especially for patients with chronic respiratory diseases, such as chronic obstructive pulmonary disease and bronchial asthma, after being stimulated by cold air, the sensitivity of respiratory tract increases and airway hyperresponsiveness will appear. In addition, the immunity of the elderly declines, and viruses and bacteria will take advantage of it, leading to the recurrence and aggravation of chronic respiratory diseases.

Cold on cardiovascular system

It will also cause many adverse effects.

When the temperature drops and the human body is in a low temperature state, the peripheral blood vessels will contract, thus reducing perspiration. This is one of the normal compensatory reactions of human body. However, due to the vasoconstriction of elderly patients, vascular resistance and heart load increase, blood pressure will increase and blood supply to the heart and brain will decrease. Cold plays an important role in the pathogenesis of hypertension.

The distribution of hypertension population in China is high in the north and low in the south. It was found that the average systolic blood pressure of men increased by 65438±0.5 mmhg and that of women increased by 2.4mmHg when the outside temperature decreased by 65438 00℃. A study in Japan also found that the prevalence of hypertension was 37% in summer and 49% in winter. As the temperature drops, the incidence of coronary heart disease, angina pectoris and myocardial infarction will also increase. A British study found that when the natural temperature dropped from 65438 07℃ to below 0℃, the daily mortality rate of myocardial infarction per million people increased from 4.9% to 6.9%.

In China, the incidence of acute myocardial infarction is relatively high from 12 to February of the following year, especially in the continuous low temperature, rainy and windy weather. Winter is also the season of high incidence of cerebrovascular diseases.

third

Cold can also affect the health of bones and joints.

Patients with osteoarthritis often have more serious symptoms in winter. Because cold can cause joint blood supply disorder, make the blood circulation in bone not smooth, increase the pressure in bone and joint, and lead to joint pain and synovitis. In addition, it is cold in the north in winter, so people spend less time going out and lighting time is shortened. For elderly patients with osteoporosis, it is easy to further aggravate osteoporosis if they do not get enough ultraviolet radiation.

A warm climate is good for heart and lung health.

If you spend cold winter in a warm place, the above problems can be avoided. The humid and warm climate in the south is definitely a great gift for the elderly with chronic respiratory diseases. Every recurrence of chronic inflammation of respiratory tract is harmful to respiratory tract. Chronic respiratory diseases caused by long-term injury will reduce the reserve capacity of the respiratory system and accelerate the aging of the respiratory system. Cardiovascular and cerebrovascular systems are the same, and long-term blood pressure stability avoids the damage of various related organs. The south is warm, with long sunshine hours. Everyone likes outdoor activities, and the improvement of osteoporosis is more obvious.

Cold is not without its merits.

But cold is not our enemy, nor is it useless. We should know the benefits it brings us. In cold weather, the oxygen content in the air will increase. Cold can kill some harmful bacteria. At the same time, cold weather can also help people improve blood circulation, raise the level of hemoglobin, shrink pores and reduce pain. In addition, in cold weather, people's fatigue and stress will also be alleviated. We should make full use of these advantages and carry out physical exercise step by step when the body can bear it. Just keep your head, feet and back warm during exercise to prevent frostbite.

Although some patients with basic respiratory tract and cardiovascular and cerebrovascular diseases go to the south for winter in cold winter, the recurrence of basic diseases can be avoided. But it is not recommended for everyone to do this, because adapting to the cold and exercising properly will increase the reserve capacity of various organs of the human body and prolong life, which is beneficial in the long run.

West Island, Sanya, Hainan: Take parents in their 80s to visit the West Island.

Video loading ...

In the morning, when the first morning light in Sanya rose, I mobilized Xiaobai to go to the apartment for the elderly where my parents lived, and prepared to take them to visit the West Island. Actually, it's not very far. Soon I went to the downstairs where my parents lived, called my mom and told her that my parents who had had breakfast would come soon, took my mom's hand and pushed my dad to the front of the car, helped my dad get on the bus first, then put the wheelchair in the trunk of the car, fastened the seat belt and set off. The car drove for ten minutes and arrived at the dock. Fortunately, I came early. There are not many cars in the parking lot. I found a better parking space, parked my car and helped my father get into a wheelchair and pushed it to the ticket hall. Here, the 80-year-old man can only go to West Island if he signs the exemption document, signs his handprint and buys a ticket with the document. If the elderly don't give discounts, all round-trip tickets will be given to 98 yuan. It's really troublesome to get on the boat in a wheelchair because it's inconvenient to move. Fortunately, dad can still walk, get on the boat and sit down. It takes 15 minutes to get to Xidao Wharf. The sea near the pier is very clear, and there are many fish swimming around in the water. Out of the service hall, I rented an electric car for two people. It's a pity that the three of us, my mother dare not drive. Only I took my parents and left in an empty wheelchair. I need to remind you that it is not far from the service hall to Xidao fishing village. It's only a few minutes' walk, or you can walk along the seaside to the village entrance. The seaside scenery is quite good. You can take photos, go to the beach to play, go swimming in the beach, take a speedboat and so on. , you can reach the village leisurely. The point is, we rented a car in the service hall, 2 hours 100, and the deposit was 300. However, two hours is far from enough for sightseeing. Rent villagers' electric cars at the village entrance, and each person only needs 10-20 yuan. There are many models, including single and double. Of course, nobody is to blame for this phenomenon. Everyone should be alive. I took my parents to the dock of the fishing village. There are not many fishing boats moored here. There are seafood caught by fishermen there, which should not be farmed. It's almost noon. My mother asked for a catty of Tsing Yi 80 and three sea urchins, each 10, which were processed at fishermen's home. I ordered another plate of fried papaya 20 yuan. After lunch, I rented an electric car, just enough for three people. Fortunately, I can put down my wheelchair and go straight to Niutouling today. In fact, Niutouling is an island, but a road was built to connect with the West Island. The rocks on the ridge are rugged, overlooking the South China Sea Guanyin Buddha statue in Nanshan. A good place to take pictures and videos. There is a statue of Taurus on the ridge, which should be meaningful. I also visited a century-old house in the village. The walls of the old houses in the fishing village are all made of coral stone and local red soil, and there is a wooden boat outside. Ship wood should be a good thing. When I came to the village market, many agricultural and sideline products were shipped from the island, which was a bit expensive. According to villagers, the labor cost of building a house on the island can reach one square meter of 600 yuan. I don't know if it's true or not, but it must be expensive. I don't think I visited anything, but it took several hours. By the time I got back to the dock by boat, it was past 4 pm. Let my parents get in the car and go back. A beautiful day is over.
