Wear a mask like this to prevent "face heatstroke" Since the "mask anti stuffy artifact" is not very reliable, how to "relieve summer heat"? Wear masks in summer, there is stress! A few tips can be used to relieve discomfort and prevent facial heatstroke. First, choose masks according to local conditions. You can choose to wear different masks according to different occasions and needs. If you go to crowded places such as hospitals, subways, supermarkets or confined space environments, it is recommended to wear N95 masks or kn95 masks. If you go to parks, greenbelts and other outdoor places, you can wear civilian flat masks or general surgical masks. Because the respiratory resistance of N95 mask or kn95 mask is 8 to 10 times greater than that of ordinary mask, it requires more powerful lung function, so the "stuffy" feeling will be stronger. In particular, it is recommended not to wear a mask during strenuous sports such as running, playing ball and skipping rope. Second, masks can be changed frequently. In hot summer, it is recommended to prepare more spare masks. Once they are soaked, they should be replaced in time. At the same time, pay attention to keep away from the crowd when taking off and wearing masks. Do not pad paper towels inside the mask, which will affect the tightness of the mask and reduce the protective effect. In case of facial allergy, check and stop using unqualified masks. If you wear a mask for a long time and feel stuffy, short of breath and other discomfort, you should immediately take off the mask in a relatively open and safe place, breathe fresh air and alleviate the discomfort symptoms. Third, the key parts should be moistened. People who need to wear masks for a long time can apply moisturizing cream on the bridge of the nose, cheekbones, ear roots and other key parts before wearing them, so as to reduce the friction between the masks and the skin and alleviate facial scars. You can also pad hydrocolloid, thin foam or silicone excipients at the pressure relief place to protect the skin and reduce the mechanical friction and pressure damage caused by the mask. People with sensitive skin or wearing masks for a long time can also try other methods to fix the masks, such as fixing the belt on the button on the headband, or clamping the belt behind the head, etc. Fourth, hold a fan to relieve suffocation. When you have to wear a mask in public places, you can also prepare to hold a small fan and other cooling objects. This kind of heatstroke prevention products that do not affect the function of the mask itself is the real "artifact". Fifth, cleanse and moisturize less makeup. Use a mild soap free cleanser without essence, wash your face with warm water, and avoid vigorously scrubbing or rubbing your skin. It is recommended to choose moisturizers that do not contain spices, Oils and acne, and preferably creams, lotion, essence and spray that contain protective ingredients such as ceramide and hyaluronic acid. Moisturizers should be applied externally at least one hour before using masks. Wear masks and try not to make up. Makeup will aggravate pore blockage and lead to acne. Cosmetic residues can also contaminate the fabric of masks. If the daily routine is normal and acne occurs under the condition of light diet, it is recommended to apply some ointment externally, such as clindamycin or retinoic acid ointment, but the dosage and frequency of application must be mastered after the doctor's advice. It should be noted that some external drugs, such as adapalene (retinoic acid) or Bansai (benzoyl peroxide), will be more irritating under the mask. Those who wear masks for a long time should stop using them or use them less. (outlook new era)
