How to wear a mask scientifically under high temperature?
Recently, the temperature has gradually increased. Under the test of high temperature, wearing a mask all day is indeed a torment for many people: hypoxia, skin allergies, sweat on the face, odor in the mouth ...
What should I do if I wear a mask at high temperature for a long time and experience hypoxia?
The higher the protective performance of the mask, the greater the breathing resistance, and the wearer needs more effort to breathe to achieve gas exchange. With the increase of use time, when the inhalation resistance is too large, people will experience dizziness, chest tightness, vomiting and other discomforts. This is a typical symptom of hypoxia, especially in a high temperature environment, which is more likely to occur .
Experts recommend that you should be cautious about wearing masks for the elderly, weak, sick, disabled and other special people with cardiopulmonary functions. Whether you can wear them and how long they should wear them is recommended to consult a professional doctor. For general healthy people, if wearing a mask for a long time is uncomfortable, they must immediately take off the mask in a relatively empty and safe place, breathe in fresh air, and relieve the symptoms of hypoxia.
How to avoid secondary pollution caused by wearing masks in high temperature environment?
Masks can block bacteria, dust and harmful substances in the outside air, and can also adsorb and collect bacteria from their own respiratory tract. If you wear a mask all day long, it is likely that a large amount of bacteria and harmful substances will be contaminated on the mask. If the outside temperature is high, it will be more beneficial to the survival of these bacteria. These bacteria and harmful substances from their own respiratory tract will increase their secondary pollution.
Therefore, if you need to wear a mask all day, in hotter and hotter weather, it is best to prepare 2-3 or more masks, replace them at any time, to reduce the secondary pollution of masks on themselves.
How to avoid skin damage and infection?
The mask is worn for more than 4 hours. Due to the thin skin dermis layer of the nose bridge, cheekbones and ears, and the lack of fat layer cushioning, it is easy to cause pressure-related injuries. Coupled with the hot weather and more sweating, local skin depression or congestion may occur, and in severe cases, skin ulceration and infection may occur.
Experts believe that it is not necessary to wear a mask anytime, anywhere, but it must be carried with you. In places where the room is relatively airtight and in poor ventilation, no masks can be worn at intervals of more than 2 meters. And like the unit meeting, you are more familiar with each other, you can also not wear a mask.
Before wearing the mask for a long time, it is recommended to apply an emollient on the nose bridge, cheekbones, ear roots, etc. to keep the skin lubricated and reduce the damage caused by friction.
When I wear a mask, I can always smell a bad breath, how to crack it?
When wearing a mask, there may be two sources of odors. One is the odor from the mask, which is related to the outermost non-woven fabric of the mask. Although the non-woven fabric itself is odorless and non-toxic, if there are problems with raw materials, production technology or storage, it can cause odors. Second, it has bad breath, but it is usually used to smell and it is difficult to notice. Wear a mask to form a relatively closed cavity, coupled with high temperature, the oral odor is amplified, so bad breath was found.
If you find that you have bad breath when wearing a mask, you can prevent it from the following 5 aspects:
Gargle can remove food debris and some loose soft dirt. General fluoride mouthwash, children under 5 years of age have not been able to complete the swallowing function, it is not recommended.

2) Brush your teeth
Brushing teeth can remove food debris, soft dirt and plaque on some tooth surfaces, and massage the gums, thereby reducing the pathogenic factors in the oral environment, enhancing the disease resistance of tissues, and reducing the occurrence of various oral diseases. It is recommended to brush your teeth once after a meal and before going to bed. The brushing time should not be too short, otherwise it is not enough to remove plaque, so the brushing time is 3 minutes each time, and 3 tooth surfaces (lip cheek, tongue, palate and occlusal surface) should be brushed.
3) Teeth cleaning
The interdental space is where plaque is formed. This area is difficult to brush and must be cleaned with toothpicks and dental floss.
4) Reasonable nutrition
Pay attention to the intake of calcium, phosphorus, vitamins and trace elements fluorine. Appropriate to eat some coarser and a certain degree of hardness of food to increase the self-cleaning effect of the mouth and the massage effect on the gums. Control sugar and refined sugars, especially children who refrain from eating confectionery before going to bed.
5) Regular oral health examination
Especially those who are over 40 years old who have been smoking, drinking or chewing betel nut for a long time, should have regular oral health examination.
