So is wearing a mask really useful? Of course it is! A good mask can prevent most of the air pollution and bacterial invasion, but only if you choose the right one for your baby. For babies, do you need to wear masks when going out? Let's get to know.
What do you want to see when you choose a mask for your baby?
1. Look at the baby's age
'all little potters can wear masks!' if you think so, think about it~
Knock on the blackboard: it's better not to wear masks for babies under 2 years old!
Normal masks are basically designed for children over 3 years old. If they are worn for children under 2 years old, they can't keep close to the face, and they don't have any egg.
What's more, the stain resistance of the mask is in inverse proportion to the air permeability. Even if the mask you buy can cover your baby's face tightly, although PM2.5, bacteria and other terrorists can't get in, the air can't get in. The lung strength of the baby is much weaker than that of the adult. With more masks, especially functional masks, it will be much more difficult for the baby to inhale and exhale, and even suffocate due to breathing difficulties and lack of oxygen.
Therefore, if the weather outside is cold and the haze is serious, it is the best policy to let the baby squat at home.
2. Look at the mask material
At present, masks on the market are mainly divided into three categories: ordinary cotton masks, disposable masks (medical surgical masks), N95 masks.
1) Ordinary cotton mask
The most common function is to prevent cold, sand and big face, and the additional function is to sell cute concave shape to prevent sneak shooting, while the biggest fatal injury is not to prevent haze and infectious diseases.
Ordinary cotton masks are mostly made of cotton, gauze, wool, canvas and velvet, but these materials are not dense enough to filter fine particles in the air, so there is no way to get haze.
2) Disposable mask (medical surgical mask)
The only way to kill a disposable mask is to stop the spread of some respiratory infectious diseases. If you want to take your baby to a public place such as a hospital, or you have a cold, or you want to prevent allergic reactions caused by pollen and other things, you can use this mask.
However, haze prevention cannot rely on it. Although it can block particles above PM4, PM2.5 can not achieve the function of protection, so it is not suitable for wearing outside in heavily polluted weather.
3) N95 respirator
What does N95 mean? N means that it can protect non oil suspended particles, which are the main pollution components in haze; 95 means that the filtration efficiency is at least 95%.
Do you feel that the N95 mask has a strong protective ability? Yes, among these three kinds of masks, the N95 mask can be called "the fighter in the haze mask". It can not only effectively filter PM2.5 and other air pollutants, but also be used to protect SARS or bird flu and other serious infectious diseases.
However, because of its strong filtering ability, it also has a great impact on breathing. Many people will feel that breathing becomes difficult after wearing N95 masks.
3、 Look at the fit between the mask and the face
As mentioned earlier, if the mask does not fit the face well, PM2.5, bacteria and other dangerous molecules in the air will enter the respiratory system from around the mask, endangering health. Therefore, when choosing a mask, you should choose one suitable for your baby's face shape.
If the size of the mask is right, it should be able to completely protect the nose, mouth and chin. For N95 and other medical protective masks, it can be judged by whether the rear eye lens is foggy and whether the air leaks around the mask.
4. Look at the manufacturer
When buying masks for babies, we must buy products from regular manufacturers.
If the producers and sellers of masks are not regular, there may be safety and health problems. For example, masks are put on the market without disinfection, and there may be insect eggs or residual pesticides and chemicals in the cotton cloth and cotton wadding used. This kind of mask can not only block pollutants, but also seriously threaten the health of the wearer, even far more than the harm of external pollution to human body.
Therefore, parents should not try to be convenient, and buy "three no" children's masks at roadside stalls at will.
If you want to wear a mask, it is very important to master the method!
In addition to paying more attention to the choice of masks, we should pay attention to the following points when wearing masks, or we will wear them in vain.
1. Wash hands before wearing
It is better to wash hands before wearing the mask for the baby. In the process of wearing the mask, avoid touching the inner side of the mask, which can greatly reduce the possibility of the mask being polluted.
2. To distinguish between the inside and the outside
The structure of medical masks is complex, from the outside to the inside are water blocking layer, filter layer and moisture absorption layer, their functions are different, so it is necessary to distinguish the inner and outer layers when wearing them.
Don't wear it on both sides in turn, because the outer layer of the mask will accumulate a lot of dust and bacteria. Take turns on both sides to let the baby touch the bacteria closely.
Also pay attention to distinguish the upper and lower sides of the mask, the upper side of the nose can be shaped, which can make the mask more fit the baby's face shape.
3. Master the right method
The mask has a hood type and a strap type. If you use the N95 mask for your baby, please refer to the following picture to wear it:
After wearing, check whether the lower nose is exposed outside the mask. If the nose is exposed, the mask will be virtual. The air will avoid the mask and enter the respiratory tract directly, which will lose the significance of protecting the respiratory tract.
4. The wearing time should not be too long
Although the mask has a certain protective effect on the baby, it will also have a certain impact on the baby's breathing. Therefore, it is better to wear the mask for no more than 6 hours, otherwise it will not be able to change to fresh air for a long time, but it will reduce its resistance.
Moreover, if you often wear a mask for your baby, it will make the baby's nasal cavity and the whole respiratory tract mucous membrane not exercise, and the processing function of cold air will be artificially weakened, a little cold, but easy to catch a cold.
5. Masks should be cleaned frequently
If you choose a normal mask for your baby, you'd better take a bath every day. Before cleaning, scald it with boiling water for 3-5 minutes, rinse it with water, and then hang it in a sunny and ventilated place, so as to have good sterilization and disinfection.
Well, that's all for the health knowledge of the mask today. Kangaroo hemp is ready to scald the mask with boiling water~~
