How important is temperature and humidity in daily life?

The summer "sauna day" is coming, and all parts of the country have entered the high temperature and high humidity mode. The indoor and outdoor are very different. You can feel the strong heat flow when you walk outside, and you will sweat profusely after leaving the air conditioner... Do you have This feeling?
Generally speaking, the comfortable temperature of the human body is 19℃~27℃, and the relative humidity is 20%RH-80%RH. The changes of temperature and humidity in different seasons are closely related to our health. Too low or too high temperature and humidity will make people feel uncomfortable and must be controlled within a reasonable range. Therefore, in order to maintain a good living environment, we need to have accurate measurement equipment to adjust the temperature and humidity in the home at all times.
Next, we will understand the importance of temperature and humidity through several questions.
Why is it that the higher the humidity in summer, the hotter the body feels and the easier it is to suffer from heat stroke? Why is it that the higher the humidity in winter, the colder the body feels and the easier it is to catch a cold?
Let\'s do an experiment: prepare two rooms with the same conditions, the same temperature, and the humidity of 90% RH and 50% RH respectively. 90% RH room, why?
This seemingly contradictory phenomenon is actually caused by "water". Water has the largest specific heat of all substances in nature. In summer, when the air humidity is high, the air will store more heat, that is, "latent heat", which will affect The discharge of water from the human body makes people feel very stuffy, and it is easy to cause problems such as heat stroke. In the same way, the humidity in the air in winter is very high and the temperature is low. The water vapor in the atmosphere will absorb the heat of the human body, making people feel cold and prone to catch a cold. Therefore, it is very important to control the temperature and humidity.
Why do people with elderly and children at home have to prepare temperature and humidity sensors?
Children, the elderly\'s perception of temperature and humidity is different from that of adults. You cannot use the experience of adults to measure the elderly and children. When the indoor humidity exceeds or falls below the range of 45% RH -65% RH, you will catch a cold. The odds of it will be greatly increased, especially at the time of changing seasons, so it is very necessary to observe the temperature and humidity when there is a temperature and humidity sensor at home, and take care of the elderly and children from the side.
Why do homes with collection hobbies or green plants must have temperature and humidity sensors?
The indoor temperature and humidity have a great impact on plants and collections. If the air temperature is too high, it is easy to make the branches and leaves grow long, the petals are mildewed, the flowers fall, and it is easy to cause the spread of diseases and insects, and the air humidity is too low, and some flowers that like moist, often have yellowish leaves, and the edges of the leaves are dry, etc. Phenomenon. The requirements for indoor temperature and humidity are particularly strict for those who have collectibles at home. Antique calligraphy, paintings, cigars and other items have strict requirements on humidity, so every collector\'s home will be equipped with a temperature and humidity sensor.
Is high humidity also a breeding ground for mites?
The rainy, humid and sultry summer is often the season when mites are most likely to breed. The mattress we spend the longest time with every day may be the "hotbed" for the breeding of mites. Mites are microscopic pests that are not easily visible to the naked eye. In recent years, the problem of diseases caused by mite larvae inhabiting items such as bedding and mattresses has become more and more serious. Especially in summer, the hot and humid weather has accelerated the reproduction of mites.
On the contrary, if the humidity is lower than 55%RH, it is difficult for mites and molds to survive. The mites in this environment will absorb the water in the body and dehydrate and die within 10 days. Therefore, it is particularly important to control the indoor temperature and humidity. ah.
