Is the room seriously ventilated for a long time? Our bedroom may not be well ventilated, but such a room actually has many hidden dangers to our health, and sometimes it indirectly causes some diseases of our bodies. Let's talk about a room that is not ventilated for a long time.
1 room, not ventilated for a long time, it must be bad to think about it. The specific hazards are as follows
Bacteria multiply quickly.
If the room is not ventilated, it will smell musty.
Cause disease
Staying in a heated room for a long time, the dry environment will lead to dry mouth and sore throat. For example, one night is fine.
Too long will lead to insufficient blood supply to the brain, leading to syncope, which can be recovered by quickly switching to air circulation. It is recommended to open the exhaust device and ventilate regularly when opening the door.
The room is not ventilated for a long time, and the air becomes worse.
Harmful gases such as carbon dioxide, dust, dander, dust mites and smoke increase, oxygen decreases, formaldehyde and benzene pollution released by decorated walls, floors and furniture increases, and indoor inhalable fine particulate suspended pollutants increase. If it is inconvenient to change the building structure, it is recommended to use humidifiers and air filters indoors.
When the air humidity is too high, it is easy for people to engage in wet prostitution.
When the humidity is too small, what needs to be prevented is "dryness" (also called "dryness"). Experiments show that when the relative humidity is 50% ~ 60%, the human body feels most comfortable and is not easy to get sick. Too much or too little air humidity is not good for human health. When the humidity is too high, the amount of pineal hormone in the human body is also large, so that the concentration of thyroxine and adrenaline in the body is relatively reduced, so that cells will be "lazy" and people will feel listless and depressed. Working and living in places with high humidity for a long time (such as mountains and islands) is also prone to rheumatism, rheumatoid arthritis and other damp arthralgia. If the humidity is too small, evaporation will be accelerated. Dry air will easily take away water from the human body, which will chapped the skin, stimulate the oral cavity and nasal mucosa, and cause symptoms such as thirst, dry cough, hoarseness and sore throat. Therefore, the invasion of dry cold air in autumn and winter is easy to induce pharyngitis, bronchitis, pneumonia and other diseases.
Modern medicine has also confirmed that the air is too dry or humid, which is beneficial to the reproduction and spread of some microorganisms. Scientists have determined that when the air humidity is higher than 65% or lower than 38%, microorganisms reproduce fastest; When the relative humidity is 45% ~ 55%, the bacterial mortality rate is high. It is precisely because air humidity affects human health that people should not only pay attention to temperature and rain, but also pay attention to humidity changes in the air in their daily lives.
Under the premise of mastering the changing law of four seasons (generally high humidity in spring and summer and low humidity in autumn and winter), be good at adjusting indoor air humidity, such as opening windows less in rainy or foggy days in summer to avoid excessive indoor humidity; When the rain clears and the temperature rises, attention should be paid to ventilation and lighting to keep the indoor humidity within a suitable range. When heating indoors in winter, it is best to use heating equipment with humidification function. If not, you can humidify yourself, such as sprinkling some water on the indoor floor, or baking something damp to improve the humidity.
It is not good from the perspective of geomantic omen or science. Mysterious terms in geomantic omen. From a scientific point of view, poor light will make the room dark and humid, and it is easy to breed bacteria. It also has a bad influence on people's minds.
No ventilation for a long time. What if room 2 is not ventilated?
1, break the wall and open the window
The room is not ventilated, which can be solved by decoration. In the process of structural transformation, windows can be opened or knocked off directly at the position of non-bearing walls to make them fully open or partially open. For example, the bedroom is connected to the study, and the bathroom and bedroom are separated by glass, which can make the indoor air better circulated.
2. Exhaust fan or fan
As a positive or negative pressure fan, the exhaust fan can realize indoor ventilation through air supply and exhaust. However, the exhaust fan has a relatively small exhaust volume, limited practical space and uncontrollable noise, and is generally only used in kitchen and bathroom space.
Fans can speed up indoor and outdoor air circulation. Place fans at the door and let them blow inward. In this way, the indoor pressure is greater than the outdoor pressure, and the indoor pollution gas is easily discharged under the dilution of fresh air. However, the position of the fan may hinder the passage, so you can choose it yourself.
3. Fresh air system
Fresh air system is an independent air handling system composed of air supply system and exhaust system, which is mainly used for indoor air purification and ventilation. Fresh air system can ensure that the air is always in a dynamic state, which is the most effective way to solve the indoor air circulation at present, and compared with exhaust fans, fans and air conditioners, fresh air system can run continuously.
If only one room in the house is poorly ventilated, you can use wall-mounted fresh air. If there is a problem with the air circulation in the whole house, you can use the central fresh air. It is worth noting that the wall-mounted fresh air needs to be drilled in the wall, and the central fresh air needs to be planned before renovation.
Step 4 plant green plants
In the case of poor indoor ventilation, you can plant some plants that purify the air, such as chlorophytum, Clivia, etc., which are not only beautiful but also absorb toxic gases. Chlorophytum and Clivia can release 80% oxygen in one night. In a room of more than ten square meters, two or three pots of Clivia can absorb indoor smoke.
