Unbelievable! When taking a shower, the body actually has this need

Some people are deeply immersed in the daily routine of taking a bath. Listening to the song, humming a few lines when I'm happy, and listening to the reverberation produced by the bathroom and the water flow, I inexplicably feel like a superstar.

When it comes to taking a bath, after washing away the dirt and fatigue, the muscles and nerves relax, the brain secretes dopamine, and even when looking in the mirror, you feel much more handsome (beautiful)~ However, do you know why people want to sing more and are more likely to have inspiration when taking a bath? Is it better to take a bath in the morning or at night? Which parts of the body should not be neglected when taking a bath?

1. Why do you always want to sing when you take a bath?

As to why people want to sing more when taking a bath, the Arab historian Ibn Khaldun gave a wonderful explanation: "When enjoying a hot bath, the hot air they inhale warms their souls, and they often sing for joy." For most people, taking a bath is a rare relaxing time in the day. When the brain relaxes, it secretes dopamine, which makes people more relaxed and happy, and it is easier to sing when they are happy. In fact, the more important thing is that people sing better when taking a bath than when singing at other times. Because ordinary bathroom tiles do not absorb sound, the walls, floors and sprayed water droplets are more likely to reflect sound. In addition, the bathroom space is small, so the reverberation of the sound will be better when taking a shower, and the songs will sound particularly beautiful.

2. Why is it easier to get inspiration when taking a shower?

People have two different modes when learning and thinking: focused mode and divergent mode. Focus mode is when you concentrate on learning or understanding something, and only local neural connections are activated, which helps you solve practical problems, such as performing arithmetic operations. The divergent mode is when the human brain is relaxed. Neural signals can move over a large area in the brain, which is conducive to creativity. For example, when you are taking a shower, you suddenly think of a solution to a long-standing problem. So, when you are unable to solve a difficult problem under high concentration, you might as well take a bath to relax and switch your brain thinking mode. Maybe inspiration will burst out!

3. Is it better to take a shower in the morning or at night?

Although most people take a shower in the morning to avoid having a "crazy and cool" hairstyle after sleeping, I still want to tell you that it may be better to take a shower at night. A BBC documentary once conducted an experiment in which a female anchor swallowed an "electronic pill" that could monitor her core body temperature before taking a bath. The electronic device could record her core body temperature and degree of sleepiness before, during, and after taking a bath. The results show that taking a hot bath not only fails to reduce sleepiness, but makes people more sleepy. It takes her some time to feel sleepy after taking a bath. Not only because bathing makes people relax, but more importantly, bathing raises the body temperature. After bathing, the body temperature will continue to drop back to the normal range. This process will make people feel sleepy. So, take a hot bath one hour before going to bed, it will help you fall asleep effectively.

4. Which "private" parts of the body should not be taken care of when bathing?

Belly button: Can a belly button that doesn’t see the sun usually be dirty? In 2012, there was a study on the biodiversity in belly buttons. Scientists studied 60 belly buttons and found a total of 2,368 different species. On average, each of us has 67 species of creatures living in our belly buttons. Therefore, you should pay attention to washing your belly button when taking a bath, but don't dig it too hard or you may pierce the belly button. This will allow bacteria to enter the abdominal cavity, which can be a serious problem.

Armpits: The armpits have many wrinkles, which easily hide dirt and grime. The sweat glands distributed in the armpits are larger and are called apocrine glands. There are approximately 300 to 600 apocrine sweat glands in the armpits. The secretions of the apocrine sweat glands are relatively viscous and have no special smell themselves. They emit a foul odor after being decomposed by bacteria, so you should pay attention to cleaning them. (Spraying cologne or something doesn't work~)

Groin: The groin is an important part connecting the abdomen and thighs. Because it is very close to the external genitalia, it is often regarded as a private part. The moisture and airtightness of the groin area often become a health hazard, so you should pay attention to cleaning it.
