Guide: What should I pay attention to when turning on the air conditioner in summer? It is comfortable to stay in an air-conditioned room and blow air conditioning in summer, but you should also pay attention to some matters. Blowing air conditioning for a long time is easy to get air conditioning disease. So what should I pay attention to when I turn on the air conditioner in summer? Let me introduce it to you.

Summer comes with dryness and impatience. Many people who are afraid of heat turn on the air conditioner 24 hours a day, and it is easy to get air conditioning disease. The symptoms of air conditioning disease are similar to "cold", which is very uncomfortable. So what is the most suitable degree of indoor air conditioning in summer, which is also the most beneficial to health?

What is the optimum temperature of indoor air conditioning in summer?

The difference between air conditioning temperature and outdoor temperature is within 5℃

According to a well-known brand air-conditioning technician, for people who sit still or do light work, when the air conditioner is set at 26℃, the indoor humidity is about 50%, which is a humidity suitable for human body and human body feels more comfortable. The most suitable air conditioning temperature for human body is also 24℃ to 27℃. Driving to 26-28℃ at night in summer is most suitable for energy saving. The temperature difference between indoor and outdoor should not be greater than 5℃, which is easy to cause air conditioning disease. When the air conditioner is cooling, raising the temperature by 2℃ can save electricity by 20%.

What is the most suitable temperature for turning on the air conditioner at night?

At constant temperature, the room temperature of 28 degrees is most suitable for rest. Because at rest, the body's immunity will decline. If the room temperature is too low, symptoms such as general weakness, headache, backache, limb pain and joint pain will appear the next day. In more serious cases, it will cause diarrhea, irregular menstruation and "air conditioning disease". When people sleep, their metabolism is reduced by 30-50%, and the air conditioner should not be lower than 24℃ at night, or the air conditioner should be set on the sleep switch. Therefore, young friends should not covet to stay cool and sleep with the air conditioner on all night. At most, they switch it to night mode, as long as they can fall asleep cold, otherwise they will easily catch cold after falling asleep.

There are fewer people suffering from respiratory diseases in summer, but the number of outpatients has increased in recent years, which is related to people staying in indoor air-conditioned environment for a long time. On the one hand, the temperature is too low, on the other hand, the air conditioner is not cleaned in time, which is easy to breed Legionella and other bacteria, which makes the human body's resistance decline. Nasal congestion, runny nose, headache, insomnia and endocrine disorders are all typical symptoms of so-called air conditioning disease. One of the most important reasons for air conditioning is the excessive temperature difference between indoor and outdoor. Although the human body has a certain ability to regulate body temperature, this ability is limited. Temperature acts on the skin, causing thermoregulation by acting on the human nervous system, which makes human blood vessels contract or relax to keep the body temperature constant. The reason why the human body can maintain a constant temperature of about 37℃ is mainly due to the temperature regulation function of the skin, and the heat dissipation of the skin accounts for about 90% of the total heat dissipation of the human body.

It is difficult for the human body to quickly adjust from the hot outdoor to the cool indoor, resulting in a series of uncomfortable reactions. This is due to the lack of negative ions in the air treated by air conditioning. If the room temperature is too low, the blood vessels, sweat glands and sebaceous glands of the human body will contract, resulting in neuromodulation disorders, which are manifested as dizziness, fatigue, general fatigue, listlessness and decreased immune function. Especially easy to catch a cold, gastroenteritis, scapulohumeral periarthritis, facial paralysis and so on. And it is also a taboo for patients with cardiovascular and cerebrovascular diseases. The doctor suggested that the temperature difference between indoor and outdoor should not be too big, generally around 8℃ to 10℃. Although there may be hot weather above 38℃ in summer, the temperature is below 35℃ for most of the day, so the indoor temperature is about 26℃.

Summer is the most vigorous season of the year, and the symptoms of excessive internal heat are also the most frequent in summer, which are often manifested as dizziness, headache, loss of appetite, sore throat, swollen gums and general weakness. So summer is a critical period for human fire prevention. There are many ways to prevent getting angry in summer, and diet is an important aspect. Here are several kinds of food, which you should try not to eat in summer.

1, eat less warm fruits.

Eating more litchi, longan and apricot isothermal fruits in summer is easy to cause excessive internal heat. Litchi contains hypoglycemic ingredients, and if you eat too much, you will have a low sugar reaction. However, people with hot constitution can't eat warm fruits because they are full of energy, have difficulty falling asleep at night and have a high metabolic rate. In addition, children with fever or inflammation of an organ should try to avoid eating it. Besides litchi and longan, peaches, longan, guava, cherry, coconut, durian and apricot are also warm fruits. Eat in moderation in summer, and do not overdo it.

Step 2 eat less nuts

Nuts refer to all kinds of seed foods rich in oil, such as peanuts, walnuts, cashews, pine nuts, melon seeds, almonds and pistachios. When eating nuts in summer, you must keep a proper amount. Because the calories of nuts are very high, the calories of 50 grams of melon seeds are equivalent to the calories of a bowl of rice. For the average person, it is more appropriate to eat about 30 grams of nuts every day. Nuts have the function of generating heat in the body. Eat them in winter and eat less in summer.

Step 3 eat less meat

When the temperature exceeds 35℃, people will increase blood viscosity due to sweating, fidget and have a worse temper when eating meat. Meat contains a lot of animal protein, which will reduce the tryptophan content in the brain, leading to aggression, anxiety and aggression. Secondly, the proportion of calcium in meat is not high. Eating too much will cause the calcium concentration in the body to be too low, which will also increase people's tendency to be irritable. Excessive intake of meat will harden blood vessels and increase blood pressure. Elevated blood pressure is an important cause of emotional instability.

4. Use less spicy spices.

Summer is very hot and the temperature is very high. When cooking, use spicy seasonings (such as star anise, fennel, cinnamon, pepper, white pepper, etc. ) will make people thirsty and unbearable, and it will also cause digestive tract and urinary tract infections. Eating spicy seasoning can cause constipation, hemorrhoids, flatulence, oliguria, dysuria, kidney pain and so on. At the same time, it can also cause systemic diseases, such as angular stomatitis, pharyngitis, conjunctivitis, miliaria, heatstroke and so on. People with chronic diseases eat spicy spices, which will lead to the aggravation of their illness. Therefore, hot spices should not be used more in summer cooking.

Nine Points for Attention in Blowing Air Conditioning in Summer

1, wear socks with air conditioning at night: it is best to wear stockings when you sleep with air conditioning on to prevent your feet from catching cold. In addition, when the elderly use air conditioning during lunch break or sleep at night, they should also wear long-sleeved pajamas and cover them with thin air conditioning quilts to prevent the lungs from catching cold.

2, air conditioning placement is particular: if the air outlet of the air conditioner blows directly against the sofa or bed in the living room, the cold wind blowing on the face will make the body cold. It is best to install the air conditioner above the bed to prevent cold air from blowing directly on people.

3. The air conditioning temperature should be appropriate: the difference between the air conditioning temperature and the outdoor temperature should not be too big, and it should not exceed 5 degrees. Generally speaking, the most suitable air conditioning temperature for human body is 24℃ to 27℃.

4. Don't smoke in the air-conditioned room: Smoking in the air-conditioned room, because the indoor air is not updated by the outdoor air, harmful gases such as nicotine and carbon monoxide in cigarettes will accumulate all the time, which is harmful to health for a long time.

5. "Bath" the air conditioner regularly: There will be many flocculent attachments on the air conditioner dust filter net, among which fungi, dander and dust mites can cause allergic skin diseases or induce asthma. People who stay in such air-conditioned rooms for a long time will feel dizzy, nauseous and even induce respiratory diseases.

6. Open the window regularly for ventilation: When using air conditioning, be sure to pay attention to ventilation. It is recommended to open the window regularly every day and turn off the air conditioner to let fresh air circulate. Especially in crowded environment, it is best to turn off the air conditioner and ventilate the room after a period of use, so as to avoid respiratory infection caused by poor ventilation.

7, sweating is not suitable for blowing: when entering the room from the outside, it is best to dry the sweat with a towel first, and then turn on the air conditioner. Blowing cold air directly when sweating, pore contraction will block pores, which may easily cause physical discomfort and may also cause a cold.

8. Don't point at the air conditioning outlet: When blowing air conditioning, don't point at the air conditioning outlet. Because the air conditioning at the air outlet of the air conditioner is relatively large, and it is directly blown on the body, it is easy to catch a cold.

9. prepare a coat: especially for office white-collar workers, it is necessary to prepare a coat. Because everyone has different adaptability to temperature, some people think this temperature is just right, while others think it is too low. Therefore, when you feel cold, you can wear more clothes and do a good job of keeping warm.
