Why do you catch a cold if you don t blow dry your hair after washing it

After washing your hair, you don't blow dry, and your head gets cold. When the degree of cold in the body exceeds the limit of the body's thermoregulatory center, the thermoregulatory center is damaged, and the heat dissipation function is inhibited, and a cold occurs.

The cold is a common acute upper respiratory tract viral infection**. The clinical manifestations are nasal congestion, sneezing, runny nose, fever, cough, headache, etc., which are mostly self-limited. It occurs more often in winter and spring, and more often in the turn of seasons.

In our daily life, we find that after washing our hair, if we don't quickly dry the water from our hair, we will feel chills. So can not blow dry your hair cause a cold? Let's take a look.

If your hair is not blow-dryed, it may cause you to catch a cold. The hair follicles on the scalp are open after washing your hair, and if you don't dry the water from your hair, it will take a lot of energy to evaporate the water. Because heat absorption can take away water from the body or body surface, it can make the head cold.

Especially in winter, try to wait for your hair to dry out as much as possible before going outdoors or resting.

How to identify a cold.

Wash your hair with warm or cool water, depending on the season; Whether you will catch a cold also depends on your physique, whether you dry your hair in time after washing your hair, whether you will get a cold and other factors.

1. For people with poor physique, it is better to wash their hair with warm water in winter, and the temperature should be about 38 degrees. For people who have good physique and have always been accustomed to washing their hair with cold water, or those who like to swim in winter, it is okay to continue to wash their hair with cold water in winter.

Second, in the summer, it is needless to say that you wash your hair with cold water, but if your physique is so bad that you will catch a cold even if you wash your hair with cold water, then you have to wash your hair with warm water.

3. After washing your hair, you should dry the water in time to avoid being blown by the wind and take precautions, so as to avoid colds as much as possible, especially for people with poor physical fitness.

Note: If you wash your hair with cold water for a long time, the reaction is not obvious when you are young, and it will show up when you reach a certain age, and you will have a long-term headache and fear of cold and wind. Therefore, young people should pay due attention.

It's better not to, especially girls.

1.If you wash your hair too often, you will wash off the nutrients if you wash your hair too often, and it will become very dry, so it will fall out very much.

2.I think I should go to the ** department to let the doctor see if there is a problem with the scalp first, and if there is no problem, then talk about the shampoo.

3.I have a friend who went to the doctor and found out that it was his scalp oil secretion that clogged the pores and caused hair loss.

4.In addition, when washing your hair, do not use your nails to pick your scalp, it will hurt the cortex and cause hair loss.

5.When applying conditioner, only the ends of the hair are applied, and applying it to the scalp can also cause excess oil, clog pores, and cause hair loss!

6.Less perm and dye your hair.

7.If the hair is seriously damaged, I think Pantene Lotion Repair and Rejoicing Fruit are very good, and the three shampoos from Shiseido are also good.

8.If you have a strong oil secretion and your hair is very oily if you don't wash it for a day, it is recommended that you use some refreshing shampoo that is suitable for oily hair.

Does not cause hair loss. Things to look out for after washing your hair:

1. Scratch your scalp with your nails when washing your hairThere are many bacteria in your nails, and once the delicate scalp is scratched, it is easy to induce infection. When applying shampoo, gently push the scalp with the tips of your fingertips to remove dirt and invigorate blood.

Second, the conditioner is applied to the hair roots, because the hair follicles are opened when shampooing, the conditioner is applied to the hair roots, and the chemicals in it are easy to penetrate and clog the hair follicles.

3. Washing your hair too often will wash off the oil on your scalp, which will cause dry hair and even hair loss in the long run, especially dry frizzy hair. Shampoo directly on the top of the head. It is best not to lather the shampoo directly on the top of the head, as the shampoo can easily remain on the scalp and produce residual garbage.

Most people think that hair loss is the exclusive right of men, but do you know that women can also be bald? Didn't you know that some of your usual habits can also cause baldness in women? Let's take a look at how women can cause baldness!

Women should be careful not to blow their hair after washing their hair, and it is easy to bald.

Because of the fast pace of contemporary work, air pollution, genetic factors and other reasons, more and more women are suffering from hair loss! What can be done to improve hair loss? Let's take a look at what the ** doctor has to say.

Hair loss of more than 100 per day is considered abnormal hair loss.

The average person loses about 100 hairs a day, and more than this number is a sign of hair loss. There are three types of common female hair loss: seborrheic alopecia, bald spots and telogen effluvium.

However, the pre-symptoms of seborrheic alopecia are not significant, and some patients only notice that more hair has fallen than in the past. Later, you will notice that you will see hair on your head or at the junction, and the hair in this position will gradually become thinner at first. If left unattended, it will gradually expand outward, resulting in the Baltic Sea, and even the bald head of the whole head.

Dr. Hou also showed that many people will think that the "small hole" on the head is bald, but in fact the two are very different. Seborrheic alopecia is associated with poor hair care and changes in male hormones. Baldness is a problem with the body's immune system.

Doctors have shown that there is no medicine to eradicate seborrheic alopecia at this stage, and the most important thing is to detect and change the way of hair care as soon as possible. If the hair loss is severe, the doctor will prescribe hair growth lotion and oral medication to speed up hair growth. Patients can also take a moderate amount of nutrient supplements to promote hair growth.

Senior dietitian Zeng Xiuqiao said that 90% of hair is keratin, and the required nutrient factors are vitamin B25 and essential amino acids. If you want to "nourish" your hair, you should eat more legumes with vitamin B25, such as peanuts, soybeans, and dried fruits. Early scientific studies have also shown that L-cystine can increase the hair growth rate in patients with seborrheic alopecia.

However, the intake of these substances from food is very limited, so severe conditions require supplementation.

If your hair is not dried too loosely, it can lead to baldness, and long-term habits will continue to give your head pain, so it is important to keep your hair done when you are asleep or going out.
