Hidden killer in winter indoor air

Hidden “killer” in winter indoor air

The suitable temperature of the living room microclimate: 18-25 ° C. The weather is getting colder and colder, and people are more and more active in warm indoor spring.
  Doors and windows are tightly closed in winter, and the concentration of indoor harmful substances will gradually increase.
The harm of indoor environmental pollution caused by decoration will be more serious.
The main sources of indoor pollution are formaldehyde, benzene, ammonia and radioactive materials.
  People who absorb high concentrations of benzene in a short period of time will experience the symptoms of central nervous system anesthesia. Those with mild dizziness, headache, nausea, fatigue, and unconsciousness, and those with severe coma or respiratory failure will die.
Ammonia is colorless but has a strong irritating odor. It often attaches to the skin, mucous membranes, and eye conjunctiva, which causes irritation and inflammation, and weakens the body’s resistance to disease.
  The radon emitted from the decoration is different from other toxic gases. The radon is invisible and odorless. Even in the environment with high radon concentration, people have no sense of it.
However, the harmful effects of radon on the human body are life-long, and it is the second leading cause of lung cancer.
  When you enter public places in winter, a rush of heat will blow.
If you stay in it for a long time, you will feel a sense of suffocation.
Passenger stations, bathing centers, hotels and other public places have carbon dioxide levels that exceed standards.
According to experts, the content of carbon dioxide is a comprehensive indirect indicator for judging the pollution of the air. The content of carbon dioxide in public places should be less than or equal to 0.
15%.
  Every winter, the climate is very dry and the room lacks humid, clean air.
According to doctors, during the dry winter, the incidence of diphtheria, flu, whooping cough, meningitis, asthma, bronchitis, etc. has increased significantly, leading to many reasons for the above diseases, except that the low temperature in winter and large changes in temperature difference cause the decline of human resistance.外,还有如下两方面的原因  其一,环境湿度过低使流感病毒和致病力强的革兰氏阳性菌繁殖速度加快,而且随粉尘扩散,引起疾病流行。  Secondly, too low ambient humidity can reduce the resistance of the human respiratory system and induce and aggravate respiratory diseases.
Therefore, in a sense, overcoming dryness is overcoming epidemics.
In winter, the optimal temperature of the indoor microclimate is 18 ℃ -25 ℃, and the humidity is 45% -65% RH.
  Responding to Winter Air Pollution The humidifier can control the humidity within the humidity range that is most suitable for the human body, which can inhibit the growth and spread of germs and improve immunity.
  Pay attention to proper ventilation.
Public places such as office buildings and department stores should pay attention to increasing indoor fresh air volume.
The family opens the window for ventilation no less than twice a day, each time for no less than 15 minutes.
Households using coal stoves for heating and gas water heaters should pay more attention to installing ventilation devices.
In addition, indoor air purification equipment should be used to eliminate indoor environmental pollution and improve indoor air quality.
Do more outdoor activities and less public places.
