5 wrong ways to wear masks, everyone should be careful
Wear a mask, use the mask properly, ventilate, wash your hands frequently, and protect yourself
But will you really wear the mask correctly? Often one action is wrong, the mask is equivalent to wearing nothing! A waste of resources, and protection may not be in place! Five kinds of wrong wearing methods are specially sent to help you avoid pits!

Mistake 1: Wear "leak masks"
Many people who wear glasses have a similar experience. Once they wear a mask, their eyes are foggy.
In fact, the fogging of the glasses shows a problem: the mask is not worn well.
Because there is no fit above the mask, the exhaled gas ran onto the glasses, and viruses and other harmful microorganisms from outside also entered between the mask and the cheek.
The correct approach is to do two more steps when wearing a mask:
Press the nose and press it firmly against the chin, the tighter the better.
Mistake 2: Wear masks regardless of positive and negative
Why do you have to face dark outwards and light (white) inwards?
The mask is actually a multi-layer structure. Taking a common disposable medical surgical mask as an example, there are three layers in total. The outer layer blocks water, the middle layer blocks particles, and the inner layer absorbs moisture.
The gas exhaled by people is relatively humid, and the inner layer is in contact with the mouth and nose, which can just absorb moisture to keep the mask dry and can block pathogens. The outer layer is water-proof, the outside water vapor can not enter, protection effect
The correct way is to remember only two sentences:
The colored side faces outward, and the uncolored (white) side faces in.
Mistake 3: The hand touches the outside of the mask when removing it
Masks can block harmful viruses and bacteria, and the outermost layer must be the dirtiest.
This coronavirus has two main modes of transmission: droplet transmission and contact transmission. We blocked the droplets through the mask, and if we removed it directly with our hands, it opened the channel for the virus to spread.
If you forget to wash your hands and then rub your nose and rub your eyes, the virus enters the body unconsciously. The mask that was originally used to block viral bacteria has become a spreader of disease.
The correct way to remove the mask, remember two points:
Do not touch the outside of the mask, just take the ear strap and remove it
Wash your hands after taking off the mask, do not take off the mask if you do n’t have the conditions
Mistake 4: The mask is sprayed with alcohol or steamed at high temperature
As we said before, even the most common disposable medical protective masks have a multi-layer structure. The outer layer blocks water, the middle layer blocks particles, and the inner layer absorbs moisture.
The reason why the outer layer can block water is because of the liquid surface tension. The most common water blocking material that utilizes the surface tension of liquids is the lotus leaf. Water droplets that fall on the surface of the lotus leaf will not spread out and absorb, but only form water droplets.
The outer layer of the mask also has a similar water-blocking effect. If the mask is treated with a large amount of alcohol or high-temperature cooking, the outer layer material will be denatured, the blocking ability of water (blood, saliva) will be reduced, and the filtering function of the mask will be greatly reduced or even invalid.
In fact, as long as you have not been to a crowded public place (such as a hospital), reusable masks do not need to be disinfected.
The correct method is: For reusable masks, simply dry them in a clean and ventilated place, or store them in a clean and breathable paper bag. (The paper bag is convenient for punching and breathing)
Mistake 5: Wear a mask wherever you go
Due to the rapid increase in the number of infections recently, many friends wear masks everywhere, and masks wear out quickly.
In fact, for healthy adults, if they are alone, such as driving and walking on their own, as long as there is no particularly intensive contact with people, the risk of infection is very low, and you can not wear a mask.
