Preface
Washing hair has become a common thing in our daily life.
Washing your hair often can keep your scalp fresh, so washing your hair every day has become a Xi that most people maintain.
But as winter comes, people wash their hair less often because the weather gets colder.
But even so, people still need to wash their hair regularly to keep their scalp fresh.
After all, if you don't wash it for a long time, it will cause a lot of trouble to yourself.
But what many people don't know is that if washing hair during these 3 time periods in winter will have a serious impact on our physical health, then which 3 time periods are they?
1. Wash your hair at night
Due to the cold weather in winter, many people will enter a misconception, that is, washing hair at night so that the wind cannot blow, and it will not cause headaches.
However, many people generally find it difficult to wash their hair early when they get home from work, and there will always be delays in such and such things, resulting in washing their hair late at night.
Although washing your hair at night is indoors without going out or blowing, there will be no problem on the surface, but the real harm is that you can't see it and can't touch it.
Dr. Fan Liyun, the attending physician of the Department of Dermatology and Venereology of Tianjin Medical University General Hospital, once said that washing hair at night has the following harms.
First of all, washing your hair at night often leads to a decrease in resistance.
And now many young people have serious hair loss, not all of which are caused by stress in all aspects, as well as their own life Xi.
For example, washing your hair at night can cause hair loss and dizziness.
Just because, at night, the body's yang energy is relatively weak.
If you wash your hair at night, your head will be affected by the flow of water.
As a result, the heat in the head gradually dissipates, so that the brain is less resistant to cold.
Therefore, in the process of heating, the body's regulatory function is likely to have problems and cannot maintain a normal metabolism.
As a result, the resistance is reduced, and it is easy to cause colds, headaches and other diseases.
As for why hair loss occurs when washing hair at night, it is because during the process of washing hair, the heat dissipation of the head will be faster, and the blood supply to the head will also be disrupted.
As a result, it is not possible to properly supply nutrients to the scalp.
At this time, the scalp condition is poor, and the hair is naturally more fragile.
Coupled with external force scratching, fragile hair is vulnerable and prone to hair loss.
But compared to dizziness, hair loss is a trivial matter.
Because a series of things after washing your hair at night that cause dizziness, it is actually more serious.
Because washing your hair at night and going to sleep without drying your hair thoroughly, it is easy for moisture and cold to invade the body and cause dizziness.
Perhaps many people have a fluke mentality, thinking that it will be okay to blow dry their hair after washing their hair at night.
But know that even if you blow dry your hair, the moisture is still there.
Therefore, it is better to be cautious about your own body.
2. Wash your hair early in the morning
In the winter morning, it is also a time when many people are lazy.
After all, the warm quilt and the cold outside the quilt can easily make people lazy to sleep for a while.
In this case, there is a high probability that you will be late for work or school.
In addition, some people don't want to wash at night, so they choose to wash their hair early in the morning to wake up quickly.
As everyone knows, the harm to the body of washing hair in the morning is far beyond people's imagination.
Dr. Xiang Niu, deputy chief physician of the Department of Dermatology of the First Affiliated Hospital of Fujian Medical University, once said that washing hair in the morning has the following harms.
First of all, washing your hair in the morning may cause hazards such as colds, orthostatic hypotension, migraines, etc.
As for colds, the temperature is generally lower in the morning.
At this time, if you wash your hair again, it is easy to catch a cold, and the cold invades the human body.
The consequence is basically to cause a cold, and the cold can be a big or small disease, and it is very likely to cause some trouble indirectly.
Secondly, regarding orthostatic hypotension, which is a condition in which blood pressure drops significantly when standing quickly, it is not a disease and may be counted as a symptom.
In many cases, there are no symptoms or even asymptomatic reversal from a recumbent to a standing position, or an tilt rate of at least 60° is tested.
Initially, systolic blood pressure continues to drop by at least 20 mmHg within 3 minutes.
or both, with or without perceived malaise.
In the morning, when the hair is washed, the patient rises from the lying or sitting position to a series of positional changes, and the blood is poured into the lower limbs due to gravity, resulting in a decrease in the amount of blood returning to the heart, a decrease in cardiac output, and a decrease in blood pressure.
In this case, patients often experience symptoms of orthostatic hypotension such as dizziness and fatigue.
In addition, the reason why migraine occurs when washing hair in the morning is because the blood circulation of the human body has not returned to normal levels in the morning, and the blood runs slowly.
Therefore, when washing hair in the morning, due to the sensitive scalp, it often leads to faster blood circulation under the stimulation of water.
If you have a history of migraine, this Xi will be more likely to trigger migraine attacks.
Therefore, it is recommended not to wash your hair frequently in the morning and avoid washing your hair in the morning as much as possible.
3. Wash your hair before going out
In fact, most of this situation is aimed at young people, many young people Xi the habit of washing their hair as soon as they go out for their image.
This is originally a good Xi habit that pays attention to the image, but if this Xi habit continues to be maintained in winter, then it will also have a certain impact on the body.
Wang Xinsheng, deputy chief physician of the Department of Dermatology of the First Affiliated Hospital of Zhengzhou University, once said that washing hair before going out has the following harms.
First of all, it is best not to wash your hair before going out in the morning, especially in the cold winter, if the hair is not dried, then the pores on the head will open due to washing the hair and are easily attacked by wind chill.
As a result, headaches may occur, so it is recommended not to wash your hair if you cannot ensure that it is wiped clean and your hair is dry before going out.
After all, this act can also cause pain in the thumb joint.
However, there are not many people who can meet the above conditions for washing their hair, and many people usually go out in a hurry after washing their hair, waiting for the wind outside to dry their hair.
You know, this is easier, but the possible consequences are more serious.
Blow-drying at home may just take a little time, but if you go outside, let your hair dry naturally.
This cold wind blows into the pores, and you will find that it takes a long time for the symptoms of dizziness to subside.
Dizziness, on the other hand, is likely to lead to a bad day at work, or even at all, which can cause more serious effects and even other diseases.
Therefore, please don't bet on your physical health, after all, when things are small, they are headaches, and when they are big, they are caused by a series of various losses, which are difficult to bear.
So the question is, since the above conditions are not suitable for washing hair, when is it normal to wash hair and does not affect your health?
First of all, Dr. Wang Xia, deputy chief physician of the Department of Dermatology of the First Affiliated Hospital of Guangzhou Medical University, once said that it is best to wash your hair at noon or afternoon in one day.
Wash your hair at noon or in the afternoon to give your hair plenty of time to air dry.
Second, after washing your hair, it will also increase the blood circulation in the head, which can ensure that you have enough energy to continue working or learning Xi in the afternoon and evening.
In addition, doctors say that it is best to control the water temperature of each hair wash at 37° to 40°, and never choose too cold or too hot water.
Don't underestimate this basin of shampoo, the temperature of the water is also the key to determining the impact of shampooing on human health.
Many young people like to take cold showers and take a cold water hair with them in summer, which is harmful to the body.
After all, the head is an extremely important part of the body, and if this head can't bear it, then the rest of the body is very likely to be affected.
On the contrary, some people will choose to wash their hair with hotter water because they are afraid of cold or have a higher tolerance, but the water used to wash their hair is not always as hot as possible, and it can even be counterproductive.
According to Dr. Zhang Jing, deputy chief physician of the Department of Dermatology of the Second Xiangya Hospital of Central South University, although overheated water washing can promote blood circulation, it also has certain disadvantages.
If the water temperature is too hot, it may burn the scalp and damage the hair, so it is recommended to control the water temperature.
If the water temperature is too hot, it is very likely that the hair will dry out, frizz, and even damage the hair follicles in the scalp area, resulting in hair loss.
It can be seen that poor hair quality is not all related to toiletry products or staying up late, and it is also related to their daily behavior Xi.
In addition, in response to the question of when it is better to wash your hair, the deputy chief physician of the Department of Dermatology of the First People's Hospital of Qinzhou City once said that the number of times you wash your hair should not be too frequent.
Many people, for the sake of their own cleanliness and personal life Xi habits and hygiene Xi, will choose to wash once a day, or even twice a day.
This kind of frequent hair washing is not advisable, it is best to choose a mild and non-irritating water temperature for washing your hair, no matter what kind of irritating substance does not stimulate your scalp.
Also, try to wash your hair about twice or three times a week, and try to keep it more evenly.
And the principle of bathing is similar to washing hair, because many people usually wash their hair together when they take a bath.
Therefore, do not use too high water temperature when taking a bath, and Wang Yong, chief physician of the general medicine department of Henan Provincial People's Hospital, once said that overheating of bath water has many harms to the body.
First of all, too high the temperature of the bath water can easily dry out the skin, because too high the water temperature will cause the blood vessels in the skin to dilate, which will increase the evaporation of water.
In addition, high water temperature will also cause the oil on the body surface to be over-flushed, resulting in dry and deficient skin.
In addition, too high the temperature of the bath water can easily cause dizziness, because too high the temperature of the water will cause the capillaries on the surface of the skin to dilate, which will cause the body's blood pressure to drop.
If you pull like this, you can easily experience symptoms such as dizziness and nausea.
It can be seen how much impact some small daily life Xi have on our physical health.
Therefore, it is recommended that everyone think about their own health and pay attention to the details of this life.
