Why does the quilt smell after it is sunburned?Is this really the "smell of the sun"?Expert: Actually, it's the smell of barbecue, and the mites are scorched by the sun!
Chinese people like to dry quilts, and even the statue of Confucius on the university campus is covered with a layer of quilts by students, especially in winter, as long as it is a place that can be dried after the sun, there will definitely be quilts.
The sun-dried quilt smells like a nice smell. So do you know where this taste comes from?It's not the cotton and the quilt itself, and it's not the smell of sunlight, which doesn't have any smell, in fact, this "sun smell" comes from a small animal in the quilt - mites.
My quilt is obviously very clean, how can there be mites?I didn't see any bugs!"You can cut a small piece of sheet with a small pair of scissors and put it under a microscope to make sure your jaw drops.
How many mites do you have on your quilt?Probably more than the number of people in your community.
American biologists have done a sampling survey, a lazy man does not wash the quilt for three months, then 10 mites will be found on the quilt of 4 square millimeters. If you count the entire quilt, there are nearly 500,000 mites. Even if it is washed once a week, there will be tens of thousands of mites on the quilt of a diligent person.
A large part of the mites on the quilt are ** in the human body. Scientists estimate that an adult has about 1.5 million to 2.5 million mites, and when the human epidermis is shed, it becomes food for the mites。Mites throw parties on your quilt every day, even for the most clean, clean-minded people.
1. Dust mites. Dust mites are one of the most common mites indoors, and they like to live on mattresses, pillows, bedding, etc. Dust mites feed on the dander shed by humans, and their growth and reproduction require certain humidity and temperature conditions. The body length of dust mites is only 017—0.50mm, which is difficult to observe with the naked eye. In medicine, there is a disease called bronchial asthma, most of which are caused by dust mites, and this chronic disease is difficult to **, because dust mites are almost impossible to kill.
2. Worm mites
Worm mites mainly parasitize in human hair follicles and sebaceous glands, they feed on ** oil, and are one of the culprits of rosacea and hair loss. Sulfur soap can be used regularly to clean clothes and body, and worm mites are afraid of this.
3. Scabies mites
Scabies mites are mainly parasitic under the skin of people, and many people will feel itchy, as if something is crawling, but they can't touch it, which is the scabies mite making trouble.
The adult body of the scabies mite is round and oval, with a bulge on the back, and the color is the same as ours, showing milky white or light yellow. It is much smaller than the dust mite, with a maximum of 03mm。
When the female scabies mite lays eggs, it will dig tunnels in the epidermis layer of the human body, and after the eggs hatch, they will become larvae, and then grow into nymphs, at which time the scabies mites can eat the dead skin and skin on the human body. After 2 to 4 weeks of living on the human body, the nymph grows up, and then begins to look for a partner, repeating the old path of the parents, continuing to mate and drill tunnels.
These "tunnels" are usually located between the wrists, between the fingers, or in the skinfolds of the waist, and can cause intense itching and redness in humans. Scabies, a serious infectious disease in human beings, is the culprit of scabies.
Why focus on scabies mites?Because it is the most harmful of these mites.
The ability to reproduce is super strong, the food is very abundant, and when the temperature and humidity are right, one mite can produce the next generation in three days. A mite can give birth to 300 cubs in three months, and its cubs don't know how many generations have been born, and there is no end to the number of children and grandchildren. If human eyesight is stronger, then the totem of our ancestors' fertility cult must be mites.
Mites are most afraid of sunlight, especially in winter when the climate is dry, and the ultraviolet rays in the sun are fatal to mites at this humidity.
However, there is a time requirement for ultraviolet radiation, and it is not possible if the time is short. Drying the quilt can bring out the smell of the sun, then it proves that the quilt is dried, and the smell of the sun is the smell of the mite corpse under ultraviolet radiation.
First of all, you should wash the bedding regularly, and you can't be lazy. Washing your bedding regularly can remove dander and dirt from it, reducing mite food**.
If you're really lazy, you can use some technology and hard work to use a mite remover. The mite remover is a device that uses high-tech means to remove mites, which vibrates mites and their excrement from the surface and interior of the article through high-speed vibration and strong suction, and then sucks them out through suction, and finally completely removes mites through ultraviolet light and other disinfection methods. This method can effectively kill mites in the quilt and reduce their number.
Finally, it is necessary to keep the room ventilated, which can reduce the humidity of the quilt. Mites prefer warm, humid environments, so there are many fewer mites in the north than in the south.
Winter is not the time when mites are most active, but summer, so even if you don't cover the quilt in summer, you can take out the quilt to dry.
