13 bad habits that harm your health

1. Frequent ears

It is a bad habit to often use matchsticks, toothpicks, thin wire or small fingers to pluck out the ears, which can easily damage the eardrum.

The external auditory meatus is about 7-8 cm long, and there is a tympanic membrane at the bottom responsible for listening to the sound. When you pull out your ear and extend it slightly, you may damage the eardrum and affect your hearing. If you pierce the eardrum, you will become deaf. When you pull out your ears, your nails and ear picking tools can hurt the skin around the external auditory meatus, and external auditory canal inflammation can also occur.

A small amount of earwax in the ear will fall out or be shaken out when people talk, eat, run, or exercise.

If there is too much earwax, it will block the auditory canal and affect your hearing. If itching is uncomfortable, you can use a cotton swab to gently bring the earwax out. Never use your fingernails or ear picks to dig hard. If your ears are indeed clogged with large pieces of earwax and itching is uncomfortable, you should consult a doctor for examination and treatment, and you should not dig it yourself.

2. Just dig your nostrils

Some people have the habit of digging their nostrils, and often use their fingers to dig into their nostrils to dig. This will damage the nasal mucosa and be harmful to health.

The nasal mucosa is rich in blood vessels, interlaced into a network. The intact nasal mucosa has strong self-defense ability, and bacteria are not easy to invade. There is a lot of nose hair in the nasal cavity, which has the effect of preventing dust and bacteria from entering the respiratory tract. It is a big barrier for dust and bacteria to enter the breath.

There are a lot of bacteria on the hands of people. When digging the nostrils, it is easy to damage the nasal mucosa and destroy the nose hairs. The bacteria on the hands will then enter the injury site, causing inflammation of the nasal hairs, pain, dry nose, fever, and general malaise.

In severe cases, the bacteria will also invade the intracranial cavernous sinus through the blood vessels of the face, causing infection and causing quite serious consequences. Therefore, it is not appropriate to dig nostrils casually, and the habit of digging nostrils should be changed.

3. Read while lying down

It is a well-known fact that reading a book while lying down will damage your eyesight. However, the harm of reading while lying is more than that.

Some physiologists believe that the bed is a place for sleeping and resting. When a person lays on the bed, the area of ​​the body's gravity is increased, which buffers the body's physiological rhythm. This is exactly the information that people sleep.

However, reading a book while lying down will continuously release signals from the brain, forcibly changing the slowed physiological rhythm of the human body. Over time, it will make the body's physiological rhythm unbalanced, leading to neurasthenia and cardiovascular disease.

Some people who lie down for a long time to read books have symptoms such as trance and confusion due to the loss of balance of their physiological rhythm. Over time, they can also cause various diseases such as bone disease and anemia.

4. Read books and newspapers while riding

Many people like to read books and newspapers while riding a train or a car. This spirit of cherishing time and craving knowledge is commendable, but from the perspective of protecting health, this is inappropriate. Regardless of whether you take a train or a car, there are many people in the car and insufficient light. If you read a book for a long time, it will inevitably put a heavy burden on your eyes and damage your eyes.

On the other hand, when the vehicle is moving, it shakes from side to side and jumps up and down, so that the distance between the eyes and the books and newspapers varies, the handwriting is not clear, and the light changes constantly. To see the handwriting on the books and newspapers, you must constantly Adjusting the focal length can easily cause fatigue of the optic nerve and easily lead to myopia; excessive fatigue of the optic nerve will inevitably cause serious damage to its health. Therefore, it is not advisable to read books or newspapers while the vehicle is swaying.

5. Reading books and newspapers in the sun

Some people like to read in the sun in the winter or in the hot and cold spring and autumn seasons. I think that this way you can bask in the sun without delaying reading and studying. In fact, this approach is inappropriate. Reading in the sun and letting the sun shine directly are harmful to the eyes.

Sunlight contains infrared rays and ultraviolet rays that are invisible to human eyes. If the human eyes are directly exposed to ultraviolet rays for too long for too long, it will damage the cells on the black eyeballs, causing severe pain in both eyes, and it will take a few days to recover normal.

Even if the sunlight is not directly irradiated to the eyes and the book is read under the sunlight, the reflected light of the paper is too strong and dazzling, which makes people feel uncomfortable and makes the eyes suffer from photophobia and pain. Over time, it will hurt your eyes. Therefore, reading in the sun is inappropriate.

6. Read books and newspapers while using the toilet

Some people are used to getting a newspaper or a book while going to the toilet. This approach has fewer advantages and more disadvantages. Reading books and magazines while using the toilet will not only suppress the bowel consciousness, but also interfere with the brain's command of the bowel conduction nerves and prolong the time for bowel movements. Too long squatting in the toilet will hinder the return of blood from the pelvic veins, dilate the blood vessels, and easily induce hemorrhoids; or even lose the sensitivity of the rectum to fecal stimulation, which can cause constipation over time.

Too long squatting in the toilet will also cause temporary insufficiency of blood supply to the brain. When standing, it is prone to syncope, falls and other phenomena. Especially those who are chronically ill, frail and elderly, are more prone to accidents when standing. In addition, the toilets are generally dim and lack of light. Reading books and newspapers there is also detrimental to eye care. Develop regular daily bowel movements. The toilet time should not be too long. In particular, you should avoid reading books and newspapers during the toilet time. Even if you have difficulty in bowel movements, you should not squat for a long time.

7. Sitting on the sofa for a long time to read

Some people like to sit on the sofa and read books, thinking that this is both comfortable and can read and study for a long time, not easy to fatigue.

It is not necessary to do this for a short time, but it is inappropriate to do so for a long time, and it is harmful to the human body.

The seat of the sofa is very low, plus the elasticity. After sitting up, the arm is depressed, the back muscles are elongated at the back of the pelvis. At this time, when looking at the sun, if the book is raised with both hands, the back, neck and eyes Although it is comfortable, the two arms will not be able to support for a long time, and it is necessary to sag. This will cause the two eyes to look down. For a long time, the lower eye muscles will be fatigued.

If you straighten your body and read your book with your head down, the back muscles in your neck are stretched again due to the gravity of your head. The same muscle has been stretched in the pelvis and then in the neck. This time will inevitably make people feel backache and neck pain, and it is easy to get cervical-related diseases after a long time.

Therefore, it is not advisable to sit on the sofa for a long time to read a book, let alone develop the habit of reading on the sofa often.

8. Suppress crying

Since its inception, there has been a saying "a man has tears but not flicks", which means that a man should be strong and cry without moving, even if he is very sad and sad, he should hold back. From the perspective of physiological health care, it is quite unsuitable.

A psychologist once conducted an investigation. He divided some adults into two groups according to their blood pressure, that is, a group with normal blood pressure and a group with high blood pressure, and then investigated whether they had cried one by one.

The results of the survey are: 87% of people with normal blood pressure cried when they were sad; the vast majority of people with high blood pressure were never crying. Although it is impossible to conclude that blood pressure changes are related to crying, it is still good for people to cry when people cry when they are sad.

When in pain, people will naturally feel sad. This kind of emotion will not only cause a lot of pressure on people's spirit, but also have a series of adverse effects on people's physiology, which will make people's nerves in a state of tension, loss of appetite, and endocrine dysfunction. Without venting and forcibly suppressing, it will cause damage to human health.

If you cry out in grief and sorrow, and you can vent your grief, you can feel a lot lighter in spirit, which is undoubtedly very good for your health.

Therefore, when you encounter sorrow, you can let it go naturally, without forcibly suppressing crying.

9. Suppress yawning

Yawning is a physiological phenomenon with positive significance, and forcible suppression is not appropriate. When the body feels tired or sleepy, it can't help but yawn a few times. This is a signal that you need to rest or change to a new environment.

After watching a movie or TV, people often like to yawn. This is a kind of self-regulating movement to return to reality from the plot of the movie or TV.

To wake up after getting up in the morning or after sitting for a long time is to wake up quickly and refresh yourself. If you feel sleepy or yawn before falling asleep, the activity of the human cerebral cortex will enter a state of inhibition. The result of yawning relaxes the spirit. This is not only because of the increased oxygen inhalation when yawning, but also because of the increased meat movement in the head, chest, and thoracic cavity, and the circulatory system is improved.

It can be seen that yawning is beneficial to the body, as long as it is not under the general public or serious and formal occasions, it can be yawned naturally without restraint.

10. Suppress sighs

In general, sigh is a negative and pessimistic performance, so many people always suppress it. However, from the perspective of physiology and psychology, sighing is beneficial to health when encountering difficulties and helplessness.

When people suffer setbacks, sorrows, and anxieties, there will be a feeling of wide sea and sky after sighing; when people are panic and melancholy, sighing has a calming effect; when people are stressed or tired at work, sighing is a relaxing effect.

When you sigh, the sounds are different and have different effects. For example, vomiting the word "Yu" to nourish the liver, vomiting the word "Oh" to meditate, vomiting the word "Hu" to strengthen the spleen, and vomiting the word "Sprinkle" to clear the lungs. But pay attention to inhale and exhale naturally.

11. Inhibit sneezing

Sneezing is a physiological reflex movement of the human body. During breathing, the nasal cavity inhales some dust and pollen; when catching a cold, the blood and secretions of the nasal mucosa increase, causing the nasal mucosa to be agitated, which can cause sneezing. Sometimes, people may cause sneezing when they are emotionally excited or encounter strong light stimulation, chills, and some pain.

Sneezing is a protective reaction. Through sneezing, a large number of bacteria (especially bacteria) can be discharged from the body when sick; when the mood is bad, sneezing can be used to make the mood comfortable and stable; encounter foreign body stimulation When sneezing, foreign objects entering the respiratory tract can be sprayed out.

Suppression of sneezing can cause nosebleeds and even nasal bone fracture. If you hold your nose in order to suppress sneezing, it may also cause sinusitis and otitis media, so it is not appropriate to suppress sneezing. However, in order to prevent indecent movements when sneezing, it is necessary to grasp the nose and mouth with your hands.

12. Ignore snoring

Snoring is a manifestation of sleepless breathing, and anyone may occasionally snore. However, as we age, there are more and more opportunities for snoring.

Generally speaking, slight snoring or occasional, intermittent snoring has little effect on human health, but serious snoring or continuous screaming every night is a phenomenon that should not be ignored.

Severe snoring can damage the health of the whole body due to insufficient oxygen inhalation. Severe snorers are often accompanied by frequent awakening, easy nightmares, headaches after waking up, tiredness during the day, easy doze, etc. This is not a normal snoring, but a disease-obstructive sleep apnea syndrome.

If it is not treated in time, it will often cause severe syndrome in the long term. Therefore, the snoring cannot be ignored, and a doctor should be consulted and treated early.

13, often bring headphones

Listening to music with headphones often damages your hearing and is not good for your health.

Scientific experiments have shown that, in a noisy environment of more than 90 decibels for a long time, the hearing will gradually change; the volume of the stereo headphones reaches 85 to 130 decibels, the earphone is pressed against the external ear canal, and the external ear canal is in a closed state. This strong noise The sound pressure, which is directly transmitted to the eardrum, will produce a huge stimulus to the human auditory nerves, which can easily cause hearing fatigue.

According to research, listening to stereo music with headphones for four hours a day will cause hearing loss.

In addition, the noise generated by the stereo headphones can also cause damage to the human heart and brain, and feel dizzy, bloated, palpitations, inattention, decreased sensitivity to thinking and reaction, memory loss, and even irritability. Symptoms such as lack of patience.
