Warmth in winter, beware of “heating syndrome”

People are warm, but still uncomfortable

  In fact, the discomfort of Mr. Li’s family stems from a very common disease in winter caused by heating, which is clinically called “heating syndrome”. Patients with this disease usually suffer from dry mouth, dizziness, dizziness, chest tightness, shortness of breath, irritability, sweating all over the body, weakness of the limbs, and sore throat. In severe cases, a series of symptoms such as nostril bleeding, blood concentration, and increased blood viscosity may occur.
  The main reason for suffering from heating syndrome is that the weather is getting colder and people want the heating to be warmer. However, due to closed doors and windows, poor air circulation, and heating, air-conditioning, electric heating and other heating facilities will cause the room temperature to be too high, making the indoor air drier, increasing pollution, providing a breeding ground for the growth and spread of bacteria, causing colds, etc. The incidence of respiratory diseases has soared, and people have different degrees of internal heat and various discomforts.
  The health damage caused by heating syndrome is the upper respiratory tract symptoms such as chapped lips, dry nasopharynx, dry cough and hoarseness. Usually, these symptoms can be effectively alleviated if water is added in time. On the contrary, if the duration is too long, the mucosal secretions of the respiratory tract will be reduced, and dust and bacteria will adhere to the mucosa, which will stimulate the larynx and cause coughing, and can even directly cause bronchitis, bronchial asthma and other diseases.
  Another health damage is manifested in the cardiovascular system. As a system that promotes blood circulation throughout the body, it is self-evident for life maintenance. However, if the heating is overheated and lasts for too long, it will “rob” the body of water, resulting in increased blood viscosity, causing a decrease in blood pressure and cardiovascular diseases such as angina. At the same time, due to the concentration of blood and the increase of blood viscosity, coupled with the heat expansion of blood vessels, blood volume will be relatively insufficient, which easily increases the incidence of ischemic stroke and other accident risks.
  Moreover, in winter, people’s skin is prone to dryness and itching. The higher indoor temperature after heating will accelerate the loss of skin moisture, causing skin fibers to lose toughness and break, thereby forming irrecoverable wrinkles.
Don’t forget to replenish electrolytes while hydrating

  Since the biggest cause of heating syndrome is dry air and faster loss of body moisture, many people will take it for granted that the solution is to replenish water. How to make it up? Is it enough to drink more water? Replenishing water is not a simple matter. Sometimes I still feel thirsty after drinking a lot of water. This is because only water is replenished, but the electrolytes lost by the body are not replenished.
  The human body has a self-regulating function. When the ambient temperature is too high, in order to relieve the high temperature of the human body, the skin will sweat to lower the body temperature. In addition to losing water, sweating will also lose a lot of electrolytes. After heating, the room is dry, and the human body will lose water and electrolytes through evaporation through skin and breathing. If you just drink a lot of pure water without supplementing electrolytes, it will cause electrolyte imbalance, which is why the more you drink in winter, the more thirsty you drink.
  Therefore, in order to prevent heating syndrome scientifically and effectively, it is necessary to add water and electrolytes to the body in time to enhance the body’s immunity. For healthy adults, the easiest way to replenish electrolytes is to drink drinks containing electrolytes directly.
  In addition, in the home environment, it is very important to open windows frequently for ventilation. It is recommended that in the case of good air quality, the home should be opened twice a day for ventilation, from 8 to 10 in the morning and 4 to 5 in the afternoon, each time for more than half an hour.
People with arthritis and diabetes should use humidifiers with caution

  As for the temperature and humidity, it is recommended that the room temperature in winter should be controlled at 18-22°C. Otherwise, the temperature difference between indoor and outdoor will be too large, which may cause a cold. At the same time, remember to wear thick clothes when you leave the heated room to prevent your body from catching cold; when you enter the heated room, you must take off the thick clothes outside to adapt to the warm and dry interior.
  In winter, the most suitable air relative humidity standard for the human body should be 40% to 60%. If it is higher or lower than this value, that is, excessive dryness or excessive humidity will cause adverse effects on the human body. Under normal circumstances, when the air humidity is 55%, germs are more difficult to spread; once the air humidity is lower than 30% to 40%, the indoor inhalable particulate matter will increase in a large area, which will easily make people catch a cold. Too high, such as 70% to 90%, will cause discomfort to the human respiratory system and mucous membranes, and reduce immunity, which is particularly unfavorable for the elderly. It is likely to cause the elderly to suffer from influenza, asthma, bronchitis and other diseases.
  In terms of maintaining air humidity, you might as well put a wet towel on the radiator to let the moisture in the towel evaporate slowly, or sprinkle water frequently (floor or flower pot), or place a pot of water in front of the bed for humidification, or indoors It is a good way to grow more green plants.
  Many people are accustomed to using humidifiers when the climate is dry in winter. This is true, and it can indeed help keep the air moist. However, the use of humidifiers is also very particular. Before buying a humidifier, you first need to consider the area of ​​the house. For example, for a room of 20 square meters, a humidifier with a humidifying capacity of 270 ml/hour or more should be used; for a room of 40 or 50 square meters, a product with a humidifying capacity of 540 ml/hour should be selected. When using a humidifier, the humidifier should not be placed too close to the human body, it is recommended to be about 2 meters away from the human body. After use, pay attention to opening windows for ventilation at the right time, while keeping the room clean and hygienic, especially to reduce the amount of inhalable dust. It is recommended to pay close attention to the actual humidity in the room during the use of the humidifier, so as to make adjustments from time to time. At the same time, the humidifier should be changed every day and cleaned once a week to avoid the breeding of pathogenic microorganisms in the humidifier and prevent the microorganisms in the water from spreading into the air. In addition, patients with arthritis and diabetes should use air humidifiers with caution. Because humid air will aggravate the condition of such patients.
  Furthermore, although the weather is cold in winter, we should also take part in physical exercises as much as possible to enhance body resistance and reduce the occurrence of heating syndrome. During winter physical exercise, the amount of exercise should be reasonably arranged according to the weather conditions and personal health. The elderly and children are most likely to get heating syndrome, and this group of people cannot “cat winter” (hiding at home for the winter).
  Finally, there is diet. In addition to moisture, fresh fruits and vegetables also contain a variety of vitamins, which can promote body fluids, moisturize dryness, reduce inflammation, dispel fire, and enhance body resistance. Such as pears, apples, bananas, oranges, radishes, cabbage, winter melon, etc. are all good choices.
