How often do you usually take a shower? Which parts do you pay more attention to when taking a bath?
In April this year, German Vice Premier Robert Habek In an interview with the media, in order to save energy, called on everyone to reduce the frequency of bathing . When taking a bath, focus on cleaning the four parts of the armpits, buttocks, groin and feet.
In addition, the media also quoted the dermatologists in the report, saying that "reducing bathing is not unhygienic, and it is even good for the skin." Does that mean that the more times you take a shower, the worse it is?
1. Will taking a bath every day be harmful to the body?
Generally speaking, everyone basically takes a bath once a day. Will taking a bath every day be harmful to the body?
In fact, the main things that take a bath are the body surface metabolites, excessive secretion of sebum, sweat, pollutants (such as dust, soil and haze, etc.), as well as various bacteria, viruses and fungi.
Is it really good for the skin to take a bath and wash your hair every day? It depends on whether it is a normal requirement or over-cleaning .
If the body surface is already dirty, it is necessary to clean it every day. But if there are not so many dirty things on the surface and just bathing for "to take a bath", it may be over-cleaned and destroy the balance of the skin's bacterial flora.
For example, Dry skin insist on taking a bath every day, may make the skin dryer and more sensitive . Therefore, you must grasp the correct frequency when taking a bath, so that it is beneficial to your skin health.
How often should I take a shower? This needs to vary from person to person and depends on the situation.
- elders
- children
According to the recommendations of the "China Skin Cleansing Guide", infants (under 1 years old) are advised to take a bath twice a week before learning to crawl, and can take a bath up to 1 time the next day. If the weather is hot or the infants and young children have a large amount of activity, the frequency of bathing can be appropriately increased.
- patients with skin diseases
For patients with psoriasis, it is recommended to increase the number of bathing times appropriately, which will help soften and remove the scales, and at the same time promote the skin to absorb topical drugs.
And for healthy and normal young people, taking a bath once a day is no big problem.
It should be noted that bathing is also in the correct order. Wash your face - clean your body - wash your hair , why?
Because turning on hot water during bathing will produce a lot of hot steam, and people's pores will expand and contract, and when they are hot, the pores will open quickly. If you do not wash your face immediately, , then the cosmetics, dust and excess sebum on your face will take the opportunity to sneak into the pores . After your body adapts, you can continue to wash your torso.
The last step in taking a bath is to wash your hair.
This not only avoids the brain's blood circulation caused by alternating stimulation of hot and cold, but also reduces the risk of cerebrovascular diseases. At the same time, the scalp and hair can be fully moisturized by water after rinsing with hot water for a period of time, which is more conducive to scalp cleaning and protecting scalp health.
2. What is the "mud" that is rubbed out during bathing?
In addition to the old keratinocytes on the skin, there are sebum secreted by the sebaceous glands, sweat secreted by the sweat glands, and dust attached to the skin surface. These substances will be mixed together and attached to the skin to form dirt.
When dirt accumulates to a certain level, it is easy to rub it down during bathing, which is called "dead skin". Therefore, the "mud" that is rubbed off when taking a bath is mainly composed of dander, sebum, sweat and dust.
Why does it still have "mud" when taking a bath every day?
This is because the skin is always metabolizing, will continuously produce dandruff and skin metabolic secretions . Even if you take a bath every day to wash away dirt on your skin, new and old keratinocytes will still be replaced the next day.
So it is normal physiological to rub out "mud" when taking a bath. It is not because it is not washed clean, and don't rub the skin repeatedly because of this.
It is recommended that you rub the following parts when taking a bath.
- There are more sweat glands distributed underarms and there are many folds, so it is easy to hide dirt.
When taking a bath, remember to lift your arms and then use your other hand to massage the armpits. When rubbing, draw circles and have moderate strength.
- The skin folds in the groin are thicker, , especially for obese people, it is easy to accumulate dirt . When taking a bath, it is recommended to gently rub the groin with your fingertips, from left to right, from top to bottom, and then rinse it with warm water.
It is recommended that when cleaning private parts, wash your hands first, then wash your private parts from front to back with your hands, and finally wash your anus and around your anus.
3. Which one is better, take a shower in the morning vs. take a shower in the evening?
From a scientific point of view, the bath time does not necessarily have to be at a certain time, but it mainly depends on the effect you want to achieve through bathing. For example, taking a shower in the morning can eliminate the feeling of sleepiness after getting up and make people feel refreshed.
It should be noted that bathing is not recommended for the following 3 moments.
After drinking : After drinking, Alcohol will inhibit the function and activity of the liver, causing glycogen to not be released normally. When taking a bath, people will increase their consumption of glucose . If blood sugar cannot be replenished in time, they will easily experience symptoms such as dizziness and fatigue. In severe cases, it can also cause hypoglycemia coma .
After meal : After meals, the blood in the body will gather in the digestive system to help digest food. If you go to take a bath at this time, it will dilate the surrounding blood vessels, resulting in reduced blood circulation in the digestive system and easily lead to indigestion.
After strenuous exercise: If you take a hot bath immediately, it will cause blood vessels to expand rapidly, causing insufficient blood supply to the brain, making it easy for people to faint during bathing. And if you take a cold shower immediately after strenuous exercise, the temperature difference distance of the body can easily cause a cold, and it will also cause blood vessels to contract quickly, increase the resistance to blood circulation, and can easily cause sudden death.
"Sleep Medicine Reviews" found that the "best moment" for bathing in is about 90 minutes before going to bed .
Researchers analyzed more than 5,000 related studies on the impact of body temperature on sleep quality, and found that 10-15 minutes of warm water (about 41℃) shower or bathing in 1-2 hours before bed can help people fall asleep faster and improve sleep quality.
Our body temperature will naturally drop according to the circadian rhythm 1-2 hours before bed. If you can take a hot bath during this period, it can enhance the natural biological process of sleep inducing, thereby improving the latency period and sleep quality of sleep.
There are certain requirements for taking a bath. The time and frequency of bathing need to vary from person to person.
If you take a bath at the wrong time, in the wrong state, in the wrong water temperature, or the wrong method and order of bathing may be incorrect, it may damage your health and even cause illness.
