Girls' labia majora

Why do female labia turn black?

1. Genetic reasons: The color of the nipples or labia majora and labia minora is determined by genetic factors. For young women who have no experience of pregnancy or childbirth, even if the vulva becomes darker, it is rare. If you think she has been "played too hard", it would be very rude.

2. Excessive and frequent sexual intercourse: During sexual intercourse, the vulva is repeatedly stimulated by friction from outsiders for a long time, which leads to increased local pigmentation. Its color will become darker over time. This is a normal physiological phenomenon. At the same time, the pigment of male hormones during sexual excitement will also make the vulva darker.

3. Normal pigmentation: The color of the female genitals is affected by the deposition of melanin in the body, and this pigmentation is also related to female hormones. The intensity of this color varies from person to person and is related to the amount of melanin in the individual. Women who are born with fair skin will have a slightly pinkish tint, while women who are born with darker skin will have darker melanin in their private parts.

4. For women, after giving birth, it is mainly due to endocrine imbalance. The level of female hormones after giving birth is different from that just after giving birth. Strong changes in female hormones cause the deposition of melanin.

5. Long-term menstrual irregularities, drug irritation, inflammation, diabetes, etc. can also cause the labia to darken.

6. Women’s labia become dark because of friction caused by walking.

7. Because some detergents are not very good, it seems that many detergents are corrosive...

28. Why do young people feel trembling hands?

We know that if patients with Parkinson's disease have uncontrollable tremors in their hands, this tremor will make it very difficult for them to eat. Generally speaking, Parkinson's disease occurs more often in the elderly, but nowadays many young people report that they sometimes or habitually experience hand tremors in their daily lives. So today, let’s talk about the reasons why young people have hand tremors.

1. Fatigue of both hands

Many young people usually use their arms too much because they work on computers or other jobs that require long-term use of their hands and no rest. When they take a break, their arms shake or tremble involuntarily due to fatigue during work. The duration will increase based on fatigue, but will return to normal after a certain amount of rest.

2. Essential Tremor

Essential tremor is a symptom of unclear etiology that occurs when the hands tremble with delicate postures. For example, writing, holding wooden chopsticks, buttoning, etc. This is more pronounced when the patient is nervous, anxious, or tired. At present, there is no cure for characteristic tremors, and the only way to control the symptoms is to take medicine.

3. Impact of cervical vertebrae

Some people suffer from cervical deformation and displacement, or even more serious diseases, due to incorrect sitting and sleeping postures. The cervical vertebrae connect to several of our nerves. People with problems with the cervical vertebrae will not only suffer from headaches, chest tightness and shortness of breath, but will also suffer from hand tremors.

4. Lack of minerals

The living habits of young people are different from those of the older generation. They often have irregular schedules, rely on takeout for their three meals, and have no balanced diet. Under such conditions, the body is likely to suffer from insufficient intake of the minerals magnesium and calcium. For example, some young people who love drinking have their minerals and vitamins in their bodies destroyed by ethanol, which disrupts the balance and leads to hand tremors.

5. Hyperthyroidism

Hyperthyroidism can cause many side effects, some of which include bulging eyes, bulging blue veins, or goiter caused by hyperthyroidism. However, hyperthyroidism can also cause severe tremors in our hands. If there are hyperthyroidism patients among your relatives and friends, you can observe their daily lives and find that they have severe hand tremors.

Although hand tremors are not a big problem, if they accumulate over time, they will affect our daily lives. I have a friend who suffers from hand tremors caused by hyperthyroidism. When she writes, the characters on the blackboard that could have been quite beautiful become ugly due to the hand tremors. It's really a pity.
