What should I do when Shenzhen returns to Nantian?

Huinantian (Huinan for short): it is the name of a weather phenomenon in southern China, which usually refers to the phenomenon that the temperature begins to get warmer and the humidity begins to rise every spring. What should I do when Shenzhen returns to Nantian? You can refer to the following.

First, close the doors and windows in advance to prevent problems before they happen.

In addition to closed places, "Huinantian" can "baptize" all spaces. If it's foggy in the morning and it feels warmer, "Huinantian" may have to report for duty. At this time, all doors and windows in the house should be closed to prevent warm and humid air from entering. Some people think that it's sunny at noon, so you can open the window for ventilation, but it can't alleviate the humidity.

In fact, the main reason for the condensation of water vapor on the surface of an object is not only the humid air, but also the temperature difference between air and the surface of the object. The outdoor temperature is the highest at noon, and the temperature difference between indoor and outdoor is also the largest. At this time, ventilation sometimes leads to more serious condensation of water vapor on indoor floors and walls.

In addition, items that are susceptible to moisture and mildew should be sealed in advance.

Second, dehumidifiers are more suitable for indoor dehumidification than air conditioners.

The room of "Back to Nantian" is extremely humid, so the effect of dehumidifying with air conditioner is not ideal. Because the air conditioner dehumidifies at the same time, the indoor temperature will drop, and the room can be kept dry without opening the window. But it did not eliminate the fundamental reason of water vapor condensation-indoor and outdoor temperature difference, and even increased. Once the window is opened, the moisture regain will be more serious. Moreover, the indoor temperature is low and the body feels uncomfortable. Dehumidification with dehumidifier not only has a large amount of dehumidification, but also does not reduce the indoor temperature, which can avoid the increase of temperature difference and has a better effect than air conditioning.

Third, turn to the north wind and open the window for ventilation.

More than 80% of the "returning to the south sky" disappeared because of the cold air going south. If the weather forecast says that there is cold air going south and the local wind direction turns north, you can safely open the doors and windows for ventilation. The cool and dry north wind can take away the moisture in the home in less than half a day, and also provide dry ground and walls.

Fourth, "returning to Nantian" should pay attention to human health care.

"Back to Nantian", the south wind blows, the temperature rises suddenly, and it feels warm. Many people put on light spring clothes. However, at this time, the ground has not had time to heat up, especially the indoor ground, which is still cold and wet. Walking on it will make people feel cold in their legs, and some people will have joint pain. Therefore, when you return to the south in early spring, you can't rush to put on light clothes and pants, especially pay attention to keeping your joints warm.

The temperature and humidity of "returning to Nantian" are very conducive to the growth and reproduction of bacteria, and food and clothing are prone to mildew, which increases the probability of human infection with various digestive diseases and skin diseases. Therefore, special attention should be paid to food hygiene, clothes should be dried or ironed in time, and clothes with peculiar smell and moisture should not be worn.

"Going back to Nantian" is easy to make people tired and upset. Turn on more lights to relieve boredom, participate in social activities and physical exercise, and eliminate bad emotions.
