There are as many as 800,000 bacteria in a pair of unwashed hands, and 3.8 billion bacteria are hidden in a gram of nail polish. A recent study in the United States found that there are more kinds of bacteria in women's palms than in men. However, men and women have 150 kinds of bacteria on each hand on average, which has exceeded the researchers' expectations. The report of this study was published in the Proceedings of the National Academy of Sciences. The researchers examined the hands of 5 1 college students in detail and found 4742 kinds of bacteria. On average, there are 150 kinds of bacteria on each hand, and only 5 kinds appear on each palm of the subject, even if only 17% of the bacteria on both hands of a person are the same. At the same time, women have mastered more kinds of bacteria. Mainly staphylococcus and Escherichia coli. ,

Peeling is generally seasonal, mostly in the hot and humid season in late spring and early summer, and often recurs for many years. Except for slight itching, it will not affect your health. 1. Try to avoid mental stress and emotional excitement. Palm peeling is really annoying, especially for women who pay great attention to hand care. Irritability can't solve the problem, but it will aggravate the condition. Therefore, when peeling and itching, you can use sedatives or antihistamines appropriately to stabilize your mood. 2. Minimize contact with alkaline substances. Alkaline substances can cause peeling or aggravate peeling. Therefore, patients with seasonal desquamation should try to reduce contact with alkaline substances. If they come into contact with washing powder, they'd better wear gloves and try to choose soap or hand sanitizer with low alkalinity. 3. Special emphasis should be placed on peeling to fall off naturally.
