On October 8, Ms. Yao from Zhoukou, Henan posted a video on a social platform, complaining that her husband's pillow was burnt, which aroused the attention and discussion of netizens.
According to the video of Western Decision, the couple's pillows are as clean as new, while the other is yellow. Ms. Yao said that this is a new pillowcase, and it has changed color after washing it once and the second time it is put on.
Many netizens left messages saying that the same is true for the bed where their partner sleeps. They take a bath every day, and the pillow is still yellow.
Why do male pillows become more likely to turn yellow?
. Men's oil secretion more
"Aging and yellowing properties of human sebum component squalene dirty cotton fabrics" pointed out that human sebum contains unsaturated oil squalene , free fatty acid , triglyceride , mono-diglycerides and cholesterol , etc. Among them, polar brown-yellow products will be produced during rapid oxidation of squalene, which are the main reasons for yellowing of textiles. ①
Men's skin secretion is more oily than women. Hong Kong Sixth Hospital of Sun Yat-sen University Deputy Chief Physician of Dermatology Wu Liangcai In 2017, published an article in Health Times that men's androgen secretion does not change much until the elderly, which is also the reason why men's skin is not prone to aging. However, because male hormone activity stimulates sebaceous gland secretion, oil and sweat are secreted more, and the average oil secretion is twice that of women. ②
. Men love to sweat more than women
Men sweat more than women, and they are more likely to leave a "mark" on pillows, bed sheets . Under the same activity volume, the amount of metabolic in men is slightly higher than that in women, and the amount of sweating in men is generally higher than that in women. ③
A Japanese study also showed that men like to sweat more than women, especially during intense exercise. The reason is actually due to the need for human evolution . Men who were hunting in ancient times needed to excrete more sweat to help themselves cool down. Women, due to their lower intensity of exercise and smaller figure, they naturally sweat less. ④
3. Some men like to sleep naked on their upper body
When it is hot, many men are used to being "shanghai naked" at home. Many men also have the habit of sleeping naked, which also allows more skin to directly contact the bed sheets and pillowcases, causing oil secreted by the skin to remain on cotton fabrics.
In short, it is a normal phenomenon for men to turn yellow in pillows. My husband's skin is secreted with a lot of oil and sweat and cannot be changed; but when the fabric is found to be yellow, you can clean it as soon as possible so that you can say goodbye to the old yellow marks!
