Anyone who has ever sat on the subway or crowded the bus has had this experience
A man was seen getting up and getting out of the car
So he hurried to his seat
Sit down with a butt
At this point, suddenly realized
On the stool, there is still the "residual warmth" that others have sat on
The whole person has a feeling that it is not very good
Is this a "close encounter"?
At this point, you turn on your phone
I happened to see something like this:
Sitting on a "hot bench" that someone else has just sat on
Hemorrhoids and sexually transmitted diseases......
Is this true?
Is it really dirty to have a "hot bench" that someone else has sat on?
What's on the hot bench exactly?
First of all, the seats in public are really dirty
Especially in the summer in a hot and hot environment
Bus seats, outdoor public seats, etc
It's easy to grow bacteria
Some normal colonizing bacteria on the surface of the skin
Such as staphylococcus, corynebacterium diphtheriae,
Pseudomonas aeruginosa, Propionibacterium, etc
will leave a "memorial" on the bench
Plus everyone in the summer for coolness
Short skirts and shorts are usually worn
It's really easy to get bodily fluids and sebum as well as bacteria
Remains on a stool that has been sitting
As a result, the public seats are really dirty
But can you get an infectious disease if you sit on such a stool?
Let's take a look at the diseases that people are most likely worried about
What kind of transmission route is it transmitted
dermatosis
After all, it's skin-to-skin contact
Then the most worrying thing should be skin diseases
For skin diseases
Most of the pathogens of disease-borne by contact
In a dry and hot environment
They often don't survive for long
The human skin is originally a barrier
Bacteria want to invade
Sufficient quantity and activity are required
It is also necessary to find the "entrance" where the defense system is weak
For example, wounds on the skin
Therefore, as soon as you touch the stool the skin is intact
Then the remnants on the bench
The impact on the individual is not significant
Although the impact is not great
For some of the more contagious pathogens
Let's be careful
For example, chickenpox, cutaneous candidiasis
Scabies, ringworm and other diseases
If the patient touches the bench with the affected area for a long time
And you're in a short time
Close contact with the skin on the heating bench
Then there is still a certain possibility of being infected
But if you are wearing clothing
Then there's no need to worry too much
When you get home, remember to wash and disinfect your clothes in time
Diseases of the urological system
One might think
Does sitting on a hot bench spread anal diseases?
For example, there are rumors that sitting on a hot bench can spread hemorrhoids
Is this true?
First of all, in the case of a clothing partition
The anus or urethra does not come into direct contact with the seat
As a result, the likelihood of infection is reduced
And our anus also has a defense mechanism
Such as the sphincter in most cases
It can block the direct invasion of external bacteria
Another example is for men
Its urethra is long and has a small entrance
Bacteria are less likely to invade
Whereas, the urethra in women is short and straight
It is slightly more likely to cause a urinary infection
But just wear underwear and outerwear
The likelihood of being infected is almost zero
Hemorrhoids, on the other hand, are not contagious
Its pathogenesis is related to "sedentary" and "constipation"
Long-term alcohol consumption is associated with high consumption of irritating foods
It doesn't matter if you're sitting on a cold bench or a hot bench
Whether you sit on a bench at home or on a public bench
As long as it's sitting for a long time
Sitting on the toilet in time can also cause hemorrhoids
It has nothing to do with being infected while sitting on a hot bench
venereal disease
Common STDs include gonorrhea, syphilis,
Genital herpes, AIDS, etc
These diseases are collectively referred to as sexually transmitted diseases
It is because the main way of transmission of the disease is: sexual intercourse
This is followed by blood-borne transmission and mother-to-child transmission
So is there indirect transmission?
First of all, after the pathogen leaves the body
It's hard to survive
I want to achieve indirect communication
The conditions are extremely demanding
A sufficient number of active pathogens are required
Like buses, subway seats
Residual pathogens are not enough
Secondly, the person who is exposed to the pathogen needs to have just broken skin
It is necessary to use the damaged part just right
Repeated rubbing to contact the pathogen
And the autoimmune system is low
It is possible to be indirectly infected
This probability is lower than winning the lottery
There is no need to worry about happening at all
It should not be used as an excuse to be infected with sexually transmitted diseases
So, instead of worrying about the hot bench spreading germs
It's more reliable to change your underwear frequently
Compared to sitting on someone else's hot stool to be infected with disease
Another hot bench is even more terrifying
- A stool that is heated by the sun
The weather is getting warmer
The sun is also gradually revealing its vicious side
Stone benches in parks, seats for electric cars, etc
will be after being exposed to the sun for a long time
causes the temperature of its surface to be too high
At this time, if you don't pay attention
I sat on it with a butt
It is likely to cause skin burns or heat stroke
It is recommended that everyone sit on these "hot benches" in the summer
Test the temperature with the back of your hand first
Make sure the temperature is not hot before sitting
Otherwise, you need to pour some water and dissipate the heat before sitting
Okay, now we know if you can sit on the hot bench
Finally, a reminder to everyone
Instead of worrying about ass contagion
What should be more of a concern is the spread of the hand
Don't touch public areas outside
I have touched the public bench and the handrail of the elevator
Friends of the pillars and handrails of the bus and subway
Be sure not to rub your eyes, mouth and nose with dirty hands right away
Remember to wash your hands when you get home
Also wash your hands before eating
Practice good hygiene
Finally, I wish everyone who likes and retweets the comments
There are clean places to sit on the way to and from work!
