Open the door and window to turn on the air conditioner, or cause dizziness?Forward reminder →

Hot summer

Is it desirable to stay in the air -conditioned room for a long time?

Do you need to open the window to ventilate the air conditioner?

Answer

It is not advisable to turn off the doors and windows on the air conditioner

A set of experiments will take you to understand

Many people have stayed in the air -conditioned room for a long time

Will feel dizzy, dozing dozen

This may be the indoor carbon dioxide concentration exceeded the standard

Experts said

National Standards for indoor carbon dioxide concentration

Generally required below 1000ppm

When the indoor carbon dioxide concentration reaches 2000 ppm

The human body often feels dizziness and discomfort

Two experimenters are in a 13 -square -meter bedroom

Close the doors and windows and turn on the air conditioner

By placed observation

Real -time observation of the concentration of carbon dioxide in the house

As the time goes

Carbon dioxide concentration continues to rise

Just half an hour

It has already exceeded 1500ppm

Experts said

For home environment

This concentration has exceeded the standard

after an hour

Carbon dioxide concentration in the air

More than 2000ppm

It's constantly rising

Experiments open the window to ventilate and breathable

After 15 minutes

Carbon dioxide concentration in the room

Slowly dropped to less than 1000ppm

It can be seen that the door and window turn off the air conditioner for 1 hour

It may cause the indoor carbon dioxide concentration to exceed the standard

If you sleep in such an environment for one night

It is very likely that the hypoxia brings hidden health hazards

It is recommended to turn on the air conditioner

Put the windows and stitch the windows appropriately

For families that are inconvenient to open the window

Can consider buying a new fan

Replace the windows and ventilate air

The air -conditioned room should not stay for a long time

Be wary of "air conditioning disease"

High temperature and hot summer

Stay in the air -conditioned room for a long time

Not only dizziness, headache

It may also induce "air conditioning disease"

Knowledge science

"Air conditioning disease" is a series of diseases induced by air conditioning for a long time. When using the air conditioner, the space is relatively closed, the air does not circulate, the pathogenic microorganisms are prone to breeding, and the indoor and outdoor temperature differences are large, and the body is poorly adapted. Therefore, a series of symptoms will occur.

Abdominal pain and diarrhea

The stomach stimulates the temperature is very sensitive

Excessive temperature difference between indoor and outdoor

Gastrointestinal motility accelerates

Causes abnormal digestive function

Causes abdominal pain, diarrhea

Cold and fever

Enter from the hot outdoor to enter indoors with too low temperature

Easy to catch a cold, cough

Even asthma, pneumonia, etc.

critical illness

Neck, shoulder, waist and leg pain

Summer clothes are thin

Shoulder joint, knee joint, waist, etc.

Long -term exposure to the cool wind

It is easy to cause joints, muscle pain and other symptoms

It is easy to cause cervical spondylosis, periarthitis, etc.

Myocardial infarction

From low temperature indoors to high -temperature outdoor

Such switching

It will cause blood vessels to shrink and expand

Repeated blood pressure fluctuates, which may induce myocardial infarction

For the old man with vascular blood vessels

very dangerous
