Can I open the window at night in wet weather? What time does it open when the weather is wet?

Recently, the rain has increased and the temperature has risen. Many areas in the south have gradually ushered in the annual resurgence weather. During this time, the room will become particularly humid. If you want to ventilate and dehumidify through the window, you must pay attention to the following matters.

Can I open the window at night in wet weather?

Opening windows is not recommended for the following reasons:

1. The humidity of outdoor air will be higher than that of indoor air in wet weather, and there will be more rain at this time. If you open the window, it will lead to humidity in the house, water on the ground, quilts, sheets, clothes, food, walls and counters are easy to be damp and moldy.

2. Moisturizing weather occurs around March, and the outdoor temperature is still relatively low at night. If there are too many windows and the indoor temperature is too low, it will easily lead to colds and other discomfort.

Is it heavy to open the window when sleeping at night?

It depends on the humidity outside.

If it rains outdoors at night or the humidity is high recently, opening the window for a long time at night will easily lead to the phenomenon of heavy moisture in the body, because from the perspective of traditional Chinese medicine, heavy moisture can be divided into external humidity and internal humidity. Generally, external humidity is mostly caused by factors such as humid climate, wading in the rain, and humid life. However, internal dampness is caused by spleen losing healthy transport, persistent body fluid and water-dampness condensation. If you often open the window in rainy days, it will lead to indoor humidity and low human resistance when sleeping. At this time, indoor moisture will gradually enter the body, leading to heavy humidity such as top-heavy body and weak limbs.

However, if the air is cool at night and it is dry outside recently, choosing to sleep at night is conducive to indoor air circulation, increasing oxygen content in the air, benefiting skin metabolism and delaying skin aging. However, it should be noted that when sleeping, the human immune ability will decline, and opening the window is easy to cause colds and colds.

It's sunny in wet weather. Do you want to open the window?

You can choose the right time to open the window properly.

In humid weather, even if the sun shines during the day, the outdoor humidity will not suddenly drop, and it is still in a high humidity period. At this time, it is easy to let the moisture outside the house enter the room, which will lead to indoor humidity. It is recommended to open the window at noon or at 3-4 pm when the temperature is high and the humidity is slightly low, and avoid opening the window in the morning and evening when the air humidity is high.

skill

Although doors and windows should be closed to prevent moisture from invading in wet weather, at least half an hour should be set aside for ventilation in a day, and then doors and windows should be closed after ventilation, and then other measures should be taken to remove indoor water vapor, such as drying water drops with a dry rag and turning on the air conditioner for dehumidification for a while. Never close the doors and windows and turn on the air conditioner all day for dehumidification, which will easily lead to air conditioning disease.

What weather is not suitable for opening windows?

In addition to wet weather, there are several weather conditions that are not suitable for opening windows:

1, foggy weather

In foggy days, a large amount of pm2.5 will be released in the air, which poses a certain threat to human health. Under normal circumstances, it is not recommended to open the window in foggy days. If you have a screen window at home, you can open the window a little smaller and put a humidifier, humidifying spray or a basin of water on the heating to increase the humidity of the air and let the dust and microorganisms sink.

2. Strong wind weather

Although it is said that opening the window can speed up the indoor air circulation when it is windy, it is easy to damage the doors and windows at home when it is windy. Secondly, it is likely that some stones and sand will blow from the outside in the strong wind, thus polluting the indoor environment. So it is not recommended to open the window in windy weather.

3. When it rains lightly

In light rain, the wind speed is small, which is not conducive to the dilution and diffusion of pollutants. Various pollutants suspended in the atmosphere will form wet deposition due to the erosion of precipitation, which will aggravate air pollution. After a period of rain or after it clears up, the outdoor air will gradually become fresh and the negative oxygen ions in the air will also increase. At this time, the window ventilation effect is the best.
