World Health Day is celebrated annually on 7 April.
In that era when we didn't know that microorganisms were pathogenic, people's concept of cleanliness was only visually clean.
Even the medical staff at that time thought so, thinking that --- "The doctor is a gentleman, and the gentleman's hands are clean." ”
But the idea eventually stopped at the microbes Leeuwenhoek had discovered under a microscope.
As Buster, Lister and others proposed disinfection methods, the whole society began to realize the importance of paying attention to hygiene.
These 6 things that seem to be hygienic may not be so hygienic
There are also some seemingly hygienic habits in life, which are the culprits that lead to a decline in immunity, bacterial breeding and reproduction, if you are doing it, please correct it quickly.
First, fold the quilt immediately after getting up
As we all know, after a night of sleep, the human body excretes part of the sweat, plus there is a stratum corneum that has fallen off.
If the quilt is immediately folded up, the moisture and gas absorbed or adsorbed by the quilt will not be able to be emitted, resulting in the quilt easily forming a source of pollution, which is not good for health.
At the same time, the quilt that has evaporated through the breath of a human body is easy to breed mites, which will cause the emergence of various allergic diseases in the human body.
Therefore, do not fold the quilt immediately after getting up, first flip the quilt with your hand, and open the doors and windows to ventilate and dissipate, so that the moisture and chemicals on the quilt are naturally emitted.
Of course, the quilt should be folded or folded, not directly left alone.
Second, wipe the dishes with a towel rag
Many towel rags are mainly pure cotton, and there are many hydrophilic clumps on the cotton fibers, which will attract water molecules, so that the towel is easily wet with water.
If the towel is not dried in time, the humid environment will be easy to breed bacteria, and the repeated use of the towel is attached to a large number of bacteria, if wiped with a towel, it will cause secondary pollution.
Moreover, the tap water in the city is disinfected and purified, and the tableware that has been washed with water is relatively clean, and it can be directly opened to dry.
Third, is it healthier to wash? Detergent to wash private areas
Female friends pay more attention to hygiene, especially the temperature of the private parts is humid and easy to breed bacteria, and they will choose to buy a special cleaning liquid, but from a physiological point of view, it is not necessary to do so.
The human vagina itself has the ability to purify itself, if you blindly use the product, it is also possible to make the pH of the intimate parts unbalanced, easy to make the resistance decline and breed bacteria.
Data have shown that women who use vaginal irrigation have a 73% higher incidence of pelvic inflammatory infection than women who do not use vaginal lotion.
Fourth, often pluck your ears
Some people will worry that ear feces will be stuck in the ears and thus plucked out of the ears, but in fact, most people's ear will fall out with chewing, opening their mouths, yawning, talking, etc., and there is no need to pluck ear at all.
Repeatedly plucking the ear, if you use a hard object, it is easy to damage the delicate skin of the external auditory canal and the eardrum, which may cause ear pain. Bleeding, severe cases may cause otitis externa, middle ear infection, etc., resulting in hearing loss.
At the same time, frequent ear plucking is likely to make the ear canal sensitive, causing fungal infections in the external ear canal and even inflammation.
Fifth, wash the dishes with boiling water before eating
Boiling water and washing dishes and chopsticks can also be regarded as a unique custom of Cantonese people.
Although bacteria and viruses are very fierce, they are really afraid of high temperatures, but in order to really play a bactericidal effect, they also need to meet the following 2 conditions:
1. The disinfected items should be completely submerged in water;
2. It takes at least 5 minutes to heat and boil to 100 ° C;
Therefore, in contrast, the so-called "boiling water hot dishes and chopsticks" in daily life is actually difficult to achieve such conditions, so it is impossible to achieve the disinfection effect.
Sixth, take a shower and scrub vigorously
For northerners, scrubbing is the most comfortable time, especially when they see the skin is red, and the psychology produces a great sense of satisfaction.
However, the problem is that there is no need to wash particularly clean when bathing, and the "mud" that comes out of the bath is actually a metabolite naturally produced by human skin, such as normal metabolic shedding cells, sebum and sweat.
However, if you rub too hard, it will destroy the skin barrier, resulting in dryness, itching, etc. of the skin, and will also cause thickening and pigmentation of the stratum corneum, which will eventually lead to the scrubbing and getting darker.
Therefore, proper scrubbing can not only remove dust from the surface of the body, but also rub each other's backs, pick up soap and thus promote infection.......
