Good night, the learned Mo Yu came
【Yellow】, as a pure color
is not only commonly used in life, but also in people's mind
However, what we are talking about today is not the [yellow]
but "yellow" substance secreted by the human body
Daily life In life, we often find this situation:
The same bed, the place where girls lie is always clean and refreshing
The place where boys lie will obviously be yellow
I often hear girls complain:
"I wash my hair and take a bath every day, why does that person in my house still 'flowing yellow'?"
Is there a possibility that
is the yellow in my mind?
cough cough, just make a joke
Does it really mean that the saying
"Women are made of water, men are made of mud"?
NoNo. We still have to talk about scientific
Why do men [结结结]?
Reason 1: Men's super developed sweat glands
Men's sweat glands secretion is more than women
So men sweat more easily
Sweat is full of [acidic ingredients]
more likely to cause bed sheet pillowcase yellowing
So where boys lie there, it is easier for them to get wet the clothes, leaving traces
Reason 2: Secretion of androgens
As we all know, men's secretion of male hormones is much higher than that of women
The face and back of the human body are covered with a large number of sebaceous glands
These sebaceous glands will secrete oil and protect the patient's body. Protect the skin
After these fats penetrate into the fibers of the fabric
Unsaturated fatty acids are oxidized by air and turn yellow
This is the root cause of men's "yellowing"
