Can socks and underwear be washed together?

In the summer
Clothes are washed every day
It was a real hassle
Put your coat, T-shirt, pants and underwear in the washing machine
convenient

But there are two kinds
Some people don't wash them together

here
You must already know

Underwear and socks!

Many people think socks are dirtier than underwear, which cling to their private parts, so separate them to avoid cross-contamination during the wash.
So who's the source of the underwear and socks mix-up? Does it really cross infect? This summer it must be made clear that...
Underwear can be dirtier than socks!

What is the sanitary condition of a pair of underwear after wearing for a day?
Microbiologists study was conducted, a dirty underwear on average 0.1 grams with dung, in human waste, in addition to a quarter of the water and undigested food particles, and loss of intestinal epithelial cells and gut microbes, if the host itself is sick of e. Coli (in addition to the conventional bifidobacterium, etc.), may also carry hepatitis a virus, rotavirus, etc.
It has even been reported that "one gram of feces contains 10 million viruses, 1 million bacteria, 1,000 parasite cysts and 100 worm eggs."

On the other hand, socks can taste especially sour and refreshing if they are stuffy in airtight sneakers for a whole day.
Socks have more odor because people's feet distributed a large number of sweat glands, sweat after the product is decomposed by bacteria, produced a strong odor.
However, that doesn't mean the bacteria on your feet are any more harmful.
First of all, the bacteria on the feet are of the same type as the bacteria in other parts of the body. Most of them are normal surface colonizers.
Second, foot bacteria are concentrated in the toe seam area, which requires a similar closed, moist environment to survive, so even if transferred to other areas of the skin, it is difficult to multiply.

Therefore, cross-infection is possible if underwear and socks are washed together.
Socks will not necessarily let underwear add bacteria new species, and underwear residual excrement may let socks bacteria know intestinal pathogens such a new friend!

If beriberi is present, care should be taken with the undergarments.
One thing to watch out for is athlete's foot.
According to statistics, there may be more than 100,000 fungi on one sock of the patients with athlete's foot. If the socks with these pathogens are mixed and washed, they may be transferred to underwear or other clothes, which is easy to cause the transfer of athlete's foot, leading to tinea cruris or tinea somalis, so that the whole body itch.

However, once you have a serious fungal infection of your feet, it's not enough to wash them separately.
Because of the wide spread of fungal infection pathways, spores may remain in towels, slippers, bedsheets, etc. Spores are the propagators of fungi, which have strong external environmental resistance and wait for the appropriate time to infect the host in a hibernation like state.
Therefore, transmission can only be avoided by killing these fungi and spores more thoroughly.
Traditional washing methods lack bactericidal effect
The traditional way of washing clothes in cold water is not always effective in killing bacteria.

For one thing, it can only wash away the stain and most of the bacteria, but a few that aren't washed away will come back to life if the conditions are right.
Secondly, common detergents, such as soap and washing powder, have strong decontamination ability, but they are not specialized in sterilization. For some bacteria or fungi with strong resistance, at least 60℃ or even 90℃ water temperature can be "scalding to death".
Also, if you don't leave the clothes to dry after rinsing on a sunny day, the damp environment is more likely to harbor bacteria.
Mixing is not dangerous if it kills bacteria adequately
Key points: under normal circumstances underwear and socks can be washed together!

Now we have a lot of ways to kill bacteria, and we're all familiar with hot water and baking.
Many washing machines already have temperature-control and drying functions, and most surface microbes live at temperatures between 22 and 36 degrees Celsius. Once outside this range, most die.
Drying not only raises the temperature, it also creates a dry environment, making it harder for microbes to survive without the water that is the source of life.

For fungi such as beriberi, bleaching solution or color bleaching solution can be added in the laundry process, which will release reactive oxygen species and effectively kill the fungus.
Therefore, if the conditions allow, can achieve full sterilization, in fact, underwear and socks mixed washing is feasible.

If not psychologically

I'd better wash them separately
