Due to the influence of corona derived from Wuhan, I think that I am more concerned about disinfecting my fingers when I do everyday shopping and activities.
While I've been doing salon work for the past two months, I felt a sense of discomfort with the words of the customers that my hands were washed with soap instead of alcohol or chemicals. I launched it.
The meaning of barriers, skin, and hand washing
Recently, many celebrities have been enlightening themselves on TV and the Internet how to wash their hands.
So why do you wash your hands?
To clean your hands?
However, if you wash it to remove dirt, you cannot wash it many times a day.
This is because human skin has a barrier function, and in order for the barrier function to work properly, the epidermis must be protected.
In removing corona derived from Wuhan, it is wise to "scientify hand washing" from the viewpoint of disinfection.
Soap, foam and detergency
So what kind of hand washing is effective for that?
It's hand washing with solid foam.
Previously, the controversy over the relationship between cleaning and foam has become a hot topic in the laundry industry.
The content was that "they aren't full of foam in the washing machine, but the cleanliness has nothing to do with foam".
But then it turned around and came to the conclusion that bubbles are still important.
However, that foam is not what you want, but the condition is important and it is effective for creamy foam.
Many women wash their faces regularly, rather than scrubbing gently, with a creamy lather, isn't it?
Bubbles, soap bubbles, and spheres
Creamy foam effect Before we talk about it, let me explain the characteristics of soap bubbles.
Soap bubbles try to maintain a sphere as much as possible.
The reason is that in order to minimize the energy of the surface tension of the membrane, it is better to have a spherical surface, which is the smallest area to enclose the same amount of air.
It's difficult, but the sphere is the most efficient.
Foam, texture and adsorption
In fact, this property and the adsorption force are closely related.
In the case of coarse foam, there are experimental results that oil is drained rather than adsorbed.
But when it comes to creamy foam, it has a strong suction.
When it becomes creamy, when the same amount of soap and water are used, the creamy foam has a distorted foam shape, and the distorted foam is pulled by the force to return to the sphere, so that the adsorption force is increased. Will rise.
The more creamy it is, the higher the total area of foam and the more attractive it is.
Soap bubbles, size and possession
There are other benefits to a creamy foam.
It's time to maintain the bubbles.
It was a memory when I played with soap bubbles, but I made a big size,
"Ah, it broke right away"
Do you have any memories?
Bubbles occur because of the property that there is no difference in thickness within the same atmospheric pressure, regardless of size.
Larger size soap bubbles become unstable with a little wind, and smaller size soap bubbles have stronger stability.
Viruses, infections and channels
Viruses cannot increase by themselves (DNA type, RNA type).
By living in cells of humans and living things and making copies of themselves, they survive and multiply.
The condition in which these cells enter is called infection, and the resulting medical condition is called infectious disease.
So where does the virus get into our cells?
It enters through the in the cell wall of water-containing cells, such as mucous membranes, for feeding and removing nutrients.
This is like an automatic door and you can only enter from there.
Because, even if you forcibly break the cell membrane and enter, if the cell does not function, you will not be able to make a copy of yourself, so you will not try to invade it.
Dust, skin, and barrier function
But what about the skin that covers much of our body?
Unlike normal mucous membranes, healthy skin does not have cell membranes that have channels.
Rather, it is because new cells are already born from the inside of the body, and while they come to the epidermis, the cells themselves are desiccated and become even more inoperable, because they are surrounded by dead cells.
This dead cell and a mass of sebum are dirt.
Since the dirt acts as an armor over our surface, it is not advisable to leave enough bacteria to multiply, but excessive removal can also increase risk.
Therefore, if you wash your hands many times a day with a rush of peeling, you increase the risk.
If it gets rough and cracks, it will be directly penetrated.
Isn't this the end of the fall?
Washing your face, washing your face, washing your body, and shampooing every day, with the creamy lather, is the most important thing to keep clean and healthy.
