Is the smelly mask poisonous
Is the smelly mask poisonous? The mask is mainly used for facial protection. The mask can prevent infection, which is necessary for us to go out now. Many people may not know much about the mask. Let's find out if the smelly mask is poisonous. Is the smelly mask poisonous? 1
No, the masks are all sterilized and managed. The smell of masks is usually your own breath, and your mouth smells, so you feel smelly. In fact, most of them are your own smell. Don't think too much. Besides, gauze has its own smell, which is nontoxic. It's better to wear it boldly than not to wear it.
where does the mask smell come from?
when we put on the mask, we smell bad breath, either because of the mask itself or because of our own bad breath.
let's talk about the second possibility first. There are all kinds of bacteria living in our mouth, among which "big brother" named "odorous bacteria" is the maker of bad breath. When our mouth is not clean enough, we often smoke and drink, or we have some gastrointestinal diseases, this kind of bacteria that can produce odorous gas will breed. < P > But in the past, because there was no mask to block it, when we exhaled, it dissipated in the air.
But now wearing a mask, the exhaled gas can't be exhausted in time, and it is blocked by the mask. As a result, it is "harmful" to ourselves, and we always smell the "peculiar smell" exhaled by our mouths.
For this kind of "odor" problem, we can solve it by actively treating the primary disease and correcting the hygiene habits.
if you really can't stand it, you can try using mouthwash and chewing gum to help reduce the odor caused by your mouth.
In addition, I secretly tell you that when wearing a mask, try to use your nose instead of your mouth to breathe, which can also reduce the odor.
after talking about the odor caused by bad breath, let's explore the odor of the mask itself.
At present, the mainstream masks in the market are all made of non-woven mask made of PP non-woven fabric, which is directly paved by polypropylene spinning. Polypropylene is a thermoplastic resin polymerized from propylene, which is a non-toxic, odorless, white and transparent solid.
polypropylene itself is non-toxic and odorless, but in the production process, there are many technical requirements involved. Polypropylene pellets will produce odor due to their own degradation and the use of various additives.
can the odor of raw materials be improved? The answer is yes, China already has a high technical level in the field of polypropylene, and the quality of polypropylene granules of Sinopec and PetroChina is very good. Generally, excellent manufacturers can produce non-woven fabrics with "low odor".
if you buy a mask with strong odor, it is probably because of the special period, tight time, heavy task and shortage of raw materials, the factory temporarily changed raw materials, or some informal manufacturers chose inferior materials for profit.
Generally speaking, the odor of masks is caused by two factors. One is that the human mouth is unclean; Second, the raw material of the mask, polypropylene granules, has an odor.
Will inhaling "odor" for a long time cause cancer?
Of course, it is not reassuring to have an odor, not to mention that you have to wear a mask for more than ten hours a day. Some people question whether inhaling these odors for a long time is harmful to your health. "Polypropylene" belongs to three kinds of carcinogens, will it increase our cancer risk?
the answer is no, you can rest assured. Although the World Health Organization (WHO) International Agency for Research on Cancer classifies polypropylene into three types of carcinogens, the three types of carcinogens mean that there is no sufficient human or animal data to prove that it will cause cancer, that is, the view that polypropylene causes cancer is not reliable. Besides, the three types of carcinogens also include chlorinated drinking water, tea, etc., which are also common or often eaten in our lives, and they do not exactly indicate that they will increase the risk of cancer.
With the gradual recovery of the epidemic, the demand for masks is not as high as before. People can also buy masks of regular quality through online appointment numbers or offline to regular pharmacies, so as long as they are used correctly, there is not much health risk.

Does the mask taste normal?
A slight taste is normal.
Some masks will smell more or less, but this usually has little effect. Just don't stay too long. It's definitely okay to wear a mask occasionally. Don't be too nervous.
The mask itself is odorless, but it will go through a disinfection process when it leaves the factory. If you are sensitive to the smell, it is recommended to dry it in the vent for a while to make it clear. The smell will not affect your health.
pungent odor is not normal
Most masks have no odor, only activated carbon masks have a faint scent of activated carbon, and rubber belts have no smell.
If the mask has a strong pungent smell, it is likely that you have bought a fake mask. This mask can not only play a good protective role, but also easily cause physical discomfort.
The correct way to wear a mask
How to wear a disposable medical mask and a disposable medical surgical mask:
1. Spread the folded face completely, and pay attention to gentle movements.
2. Cover the mask over the nose, mouth and chin. If the mask is tied, the upper strap of the mask is tied to the middle of the head and the lower strap is tied to the back of the neck. If it is an ear-hanging type, it is directly hung in the ear.
3. Put your fingertips on the nose clip and shape the nose clip according to the shape of the bridge of the nose.
4. Check whether the edge of the mask fits the face.
how often do you wear a mask to replace it?
For disposable masks, wear them continuously for 4 hours, and replace them immediately after being contaminated or wet. The main reason why the mask can play a protective role is the filter layer. When the mask is wet or dirty by secretions, the protective performance will be reduced. If the mask is in short supply, it can be reused after drying naturally, but it cannot be cleaned.
The masks worn by ordinary people in normal activities, such as those worn in daily activities such as taking public transportation and buying food in supermarkets, have a small probability of carrying novel coronavirus, and need not be disinfected after use. Masks worn by suspected patients with symptoms such as fatigue and fever shall be collected and disposed of as medical wastes.
Why do masks need to be replaced regularly?
First of all, we should start with the principle. No matter whether it is a medical mask or a N95 dust mask, the filtering principle is to intercept and adsorb the particles (including dust, bacteria, viruses, etc.) in the inhaled air through the barrier layer (made of polypropylene meltblown fiber) of the mask interlayer to prevent users from inhaling harmful particles.
In addition to fiber interception, electret treatment is generally carried out on the barrier layer of the mask, so that the barrier layer is slightly charged and actively absorbs particles to enhance the filtering effect.
The barrier layer of the mask is equivalent to a large net. Therefore, even regardless of the sanitary condition of the mask, if the mesh of this large net is blocked by various particles and the mesh is filled to a certain extent, and there is not enough air to come in, we will naturally feel difficult to breathe when wearing it, and the mask will naturally be unusable.
Besides, a warm and humid mask is also a good environment for bacteria to grow. Considering that the mask is soiled by saliva and nose, it is deformed and damaged after long-term use, which affects the air tightness. In principle, the mask can't be used for a long time.
