In summer, the common diseases of white-collar workers in the air-conditioned sickroom office are distressing. The symptoms of air-conditioned diseases are often similar to "cold"; So how many degrees is the most suitable for indoor air conditioning in summer, which is also most beneficial to health?
According to an air-conditioning technician of a well-known brand, for people who sit still or are doing light work, when the air conditioning is set at 26 ℃, the room humidity is about 50%, which is the appropriate humidity for the human body, and the human body feels comfortable. The most suitable air conditioning temperature for the human body is also between 24 ℃ and 27 ℃. In the summer evening, considering the energy saving of 26-28 ℃, the temperature difference between indoor and outdoor should not be greater than 5 ℃. Too large a temperature difference can easily lead to air conditioning disease. When the air conditioning is cooling, the set temperature is 2 ℃ higher, which can save 20% of electricity.
At a constant temperature, it is best to keep the room temperature at 28 degrees. Because at rest, the immune system of the human body will decline. If the room temperature is too low, the symptoms of fatigue, headache, backache, limb pain, arthralgia and other symptoms will appear the next day, and more serious cases can cause diarrhea, irregular menstruation, "air-conditioning disease" and other diseases. When people sleep, their metabolism is reduced by 30-50%, and the air conditioning at night should not be lower than 24 ℃, or the air conditioning should be set at the sleep switch. Therefore, young friends should not try to cool down and sleep with the air conditioner on all night long. The best way is to set it to night mode.
The number of people suffering from respiratory diseases in summer is relatively small, but in recent years, the number of outpatient patients has increased, which is related to people staying in the indoor air conditioning environment for a long time. On the one hand, the temperature is too low, and on the other hand, if the air conditioning is not cleaned in time, it is easy to breed bacteria such as Legionella, which reduces the resistance of the human body. Nasal congestion, runny nose, headache, insomnia, endocrine disorders are all typical symptoms of so-called air conditioning diseases.
One of the most important reasons for air conditioning is that the temperature difference between indoor and outdoor is too large. Although the human body has a certain ability of temperature regulation, this ability is limited. The temperature acts on the skin, which causes the response of temperature regulation effect through the action on the human nervous system, and makes the human blood vessels contract or expand to keep the 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. 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 adjust quickly from the hot outdoor to the cool indoor, which will produce a series of uncomfortable reactions. This is due to the lack of negative ions in the air treated by the air conditioner. The low room temperature will also cause the contraction of blood vessels, sweat glands and sebaceous glands in the human skin, leading to nervous regulation disorder, which is manifested as dizziness, tiredness, general discomfort, lethargy and decreased immune function. It is particularly easy to suffer from colds, gastroenteritis, periarthritis of shoulder, facial nerve paralysis and other diseases, which is a major taboo for patients with cardio-cerebrovascular diseases.
The doctor suggested that the indoor and outdoor temperature difference should not be too large, generally around 8 ℃ to 10 ℃. Although high temperature weather above 38 ℃ may occur in summer, the temperature is below 35 ℃ for most of the day, so the indoor temperature around 26 ℃ is more appropriate.
