In order to keep warm in the cold winter, many families tend to turn the heating or air conditioning very warm, even a little hot.
However, long-term doors and windows are closed, coupled with heating and air-conditioning heating, indoor temperature is high, air is dry and not circulating, it is easy to cause immunity, resulting in irritability, dryness of the nose, dizziness, weakness.
These symptoms are medically known as "heating diseases."
Symptoms of heating sickness
Respiratory system
The indoor temperature is too high, and the outdoor temperature is too low, the temperature difference is too large, so you need to take off your coat when you enter the door, take off your hat and scarf, and you must be fully armed when you go out.
In this case, the human body is vulnerable to wind and cold. In addition, the warm and dry environment makes people's immune function decline, which is easy to cause a cold.
Being in a warm and dry room for a long time will cause the lips to chapped and the nasopharynx to dry. If you do not replenish water in time, it will lead to a decrease in respiratory mucosal secretions. Dust, germs, etc. will fall on the mucous membrane, stimulate the throat, cause cough, and easily cause upper respiratory tract infection, bronchitis, bronchial asthma and other diseases.
Cardiovascular System
Overheating of the heat will "grab" the body's water, causing blood viscosity to increase, causing blood pressure fluctuations and cardiovascular diseases such as angina.
At the same time, for patients with pulmonary heart disease and cardiac insufficiency, respiratory infections caused by "heating diseases" can easily lead to palpitation and chest tightness.
Urinary system
The normal person's urine volume should be 1500-2000 ml per day. This urine volume can play a role in flushing the urinary tract and avoiding urinary tract infection.
If you stay in the heating room for a long time, the amount of urine will be reduced and the urinary tract will not be flushed properly. This will increase the risk of urinary tract infections and urinary calculi.
skin
The skin is exposed to the air for a long time. If the indoor temperature is too high and too dry, the skin will not be moisturized by the humid air in the environment, which will not only lack elasticity, but also cause the skin fibers to lose their toughness and cause breakage, thereby forming wrinkles.
The skin of the elderly lacks nourishment and often has troubles with itchy skin. If the room is dry or too hot, the itching of the skin will be more serious.
How to prevent heating sickness?
Room temperature should not be too high
In general, the temperature that the human body feels most comfortable is 18 °C - 24 °C. If the temperature is too low, people feel cold and vasoconstriction, which is not only easy to catch a cold, but also easily lead to myocardial infarction or cerebral infarction.
Therefore, in winter, the room temperature is generally adjusted to above 18 °C. In rooms with heating and air conditioning, it is best to put a few basins of water in the room to increase the humidity in the room.
Timed ventilation
Open the window at least 1-2 times a day, preferably at around 9 o'clock in the morning and 4-6 o'clock in the afternoon. If the weather is too cold, the window opening time can be shorter.
If the sun is shining, the window opening time should be longer to keep the indoor air fresh and reduce the growth of bacteria and viruses.
Replenish drinking water in time
The winter climate is dry, and if the indoor heat is dry, the fluid will be lost. Therefore, winter should also pay attention to supplement drinking water to prevent the occurrence of colds, respiratory tract, cardiovascular and cerebrovascular diseases. Also, don't wait until you are thirsty before drinking water, otherwise your body has been hurt.
Bathing should not be too frequent
If you take too many showers in the winter, you can't get the water back. Instead, the water temperature is too high, rubbing hard, scalding and damaging the skin. The human skin has a protective film of grease. When the bath is too diligent, it is easy to destroy this protective film, making the skin more likely to lose moisture.
Therefore, bathing in the winter for 1-2 times a week, the water temperature should not be too high when bathing, it is not appropriate to rub hard. After bathing, it is best to apply some body lotion to moisturize the skin, which can reduce the moisture absorbed by the dry and hot environment, and also reduce the symptoms of dry and itchy skin.
Adjust diet
The winter diet should be light, moist, nutritious and easy to digest. It is advisable to eat more vegetables and fruits rich in vitamin C.
