1-18. The intestines represent the figure of a person（日本語）
Our bodies are made up of microorganisms.
Especially in the intestines, there are unknown ecosystem of countless microorganisms that keeps us healthy.
The relationship between a hundred trillion bacteria in intestines and health is very interesting.
A baby in a mother is in a completely clean condition without any bacteria, and receiving only nourishment from the umbilical cord to grow.
Babies contact with bacteria just after birth when they come out into the open air.
Then you can never be free from association with all the bacteria until you grow old and die.
Our daily life means a life with bacteria, and our physical condition, our future illness, and in some cases, our personality, are all affected by them.
In the human body, the intestine is the place where the most of these bacteria live.
What we eat is not only absorbed by the body for energy, but also part of it feeds them and supports their lives.
Their reproductive depends on what we eat.
A little bit philosophical about the relationship between bacteria and food, the way we eat has a lot to do with the way each person lives, and behind the way we live is the mindset that support it.
In other words, our bodies are made up of “what we eat” and “how we think”.
A survey by a major cosmetics manufacturer found that more than 70% of women have skin trouble on hands due to the habit of washing hands and disinfecting with alcohol to prevent the new coronavirus.
We’ve often heard the following comments from customers.
– It becomes hard to open a plastic bag because sebum of hands is taken off and dries out.
– Hands get rough from alcohol sterilization.
– They feel it necessary to need oil.
If your fingers are rough, it’s easier for the virus to get in a wound.
It is recommended to take care of it as soon as possible, because it will be dry out if you don’t wipe it off thoroughly after washing your hands.
Choosing a cleaning agent to wash hands many times is very important for the present pandemic time.
[Choose a cleaning agent that doesn’t break the skin barrier].
1. Don’t choose a synthetic detergent
2. Choose a pure soap.
3. Select a pure soap with fast dissolution speed (speed to remove dirt)
4. Choose a product that is rich in moisturizing ingredients.
5. Choose one that rinses quickly and leaves no surfactant
As I’ve mentioned in previous columns,
The FDA has announced that there is no difference in the sterilization effect between disinfectant soap and ordinary pure soap.
So, wash gently with safe pure soap and disinfect your hands only when you are out where you can not wash your hands.
Then, take care of your hands with creams and oils that don’t break the skin barrier (resident bacteria).
By the above methods, you may be able to avoid skin trouble on hands.
We tend to think of cleaning as “removing oil” or “removing dirt”.
= Cause of skin trouble.
However, pure soap focuses on how to leave the sebum and resident bacteria behind while removing dirt.
The fact means that the sebum removed too much so far can provide comfort to the resident bacteria.
ＰＤ膜分離法の場合、分離性能も向上し、孔径の５分の一の粒子まで除去できるようになります（出典：ICEAB13 Paper ID:11 尾池哲郎ら、”Model analysis and its evidence for particle removability of pressed non-woven fabric membrane”）。その結果、安価な不織布膜でも高度な膜分離が長期間に渡り可能になることが分かってきました。
