Under the normalization of epidemic prevention and control
Masks are essential
But time goes on
The "posture" of everyone wearing a mask begins to vary
Forward the reminder
The following ways to wear masks must not be allowed!
We were often on the street, in restaurants
Some people were seen suffocating because they were wearing masks
Or easy to eat
Just pull the mask under your nostrils
Even pulled to the chin
What's more, hang the mask directly on your arm
Don't laugh, I'm the schematic
Beijing Chaoyang Hospital, Beijing West Branch, affiliated to Capital Medical University
Wang Jing, chief physician of the Department of Respiratory Medicine, introduced
Wear a mask to your chin
Increases the risk of infection
Because when the mask is worn on the chin
Skin of the chin and neck
Bacteria or viruses may be present
On the inside of the mask
It will get some bacteria and viruses
When wearing the mask back to the mouth and nose
These bacteria or viruses
It will go from the nasal mucosa, the oral mucosa
Enter the respiratory tract
Thus causing infection with related diseases
"Especially this time the spread of Aomi Kerong
It is very stealthy
And the spread is very strong."
“
Experts tell us
In case of exposure to bacteria and viruses
Masks are worn on the chin
Put it back on to the nose and mouth
It can be very dangerous
This method is completely unprotective
Instead, it greatly increases the risk of infection
Besides
There are also people who wear masks for convenience
Wear a mask on your arms
The arm has a large range of motion
Bacteria and dust are easily attached
This is also very risky
Except for the incorrect posture of wearing a mask
And some friends
In order to pursue individual expression, or to be more economical
Will wear some so-called internet celebrity "transparent masks"
Or cotton masks, homemade masks
Many merchants even played the same banner of celebrities
But the material of the "transparent mask" is plastic
Neither ventilation nor filtering of virus particles can be achieved
Does not play a protective role
In this regard, disease control experts suggest
"The average healthy person
In some of the more densely populated public places
Use disposable medical masks"
Regular medical masks need to pass the air tightness test
If it does not fit the face
The protective effect will be greatly reduced
When everyone is wearing a mask
Self-testing is possible in a simple way
"The method of air tightness check is inspiration
The mask face will collapse slightly
And when you exhale, there will be bulges
This shows that the airtightness of our masks is sufficient
If we leak air from the bridge of our nose or cheeks
Masks need to be adjusted."
