My skin always has rashes and red spots. What’s going on?

Netizens asked:

I slept in a mosquito net at night, but the next morning I found many rashes and red spots on my chest, back, and limbs.

My neighbor said that since there were no mosquitoes biting, the problem might be with the new mat I bought.

I quickly removed the cool mat, and a few days later, the rash really disappeared. Could it be that the cool mat can "bite" people?

It's not the mat that "bites" people, but the bugs hidden in the mat that "bite" people.

Cool mats are easily infested with a type of insect called "mites" that are invisible to the naked eye.

The toxins released when mites bite people and the proteins in their excrement can cause allergies in the human body, resulting in papules, erythema, and unbearable itching on the skin.

In addition, the excrement and dead mite fragments of mites are strong allergens, and contact with them can induce allergic asthma in people with allergies.

Therefore, new mats or mats from last year must be disinfected with mites before use.

The most suitable living conditions for mites are between 17 and 30 degrees Celsius. When the temperature is higher than 55 degrees Celsius, the mites cannot survive for more than 10 minutes.

Therefore, mites are most afraid of high temperature and sunlight. They can be soaked in boiling water, or washed several times with clean water, and then exposed to the sun for two hours to kill the mites.

Or you can use an electric iron. First, lay out the cool mat, and then use the electric iron to iron the cool mat back and forth on the wet towel. It should be noted that you should keep the wet towel on each part for a long time, so that the high-temperature steam can kill the mites.

Remember to follow this method to remove mites and sterilize the mat once a week.
