The 10 most harmful things to your body

1. Hair is most afraid of hair dye

Benzene compounds such as p-phenylenediamine in some hair dyes can penetrate into part of the hair cuticle and cause peroxidation reaction, causing the hair to dry, break, or even fall out. Perming is also extremely harmful to hair. Middle-aged and elderly friends should not dye their hair more than twice a year. When dyeing their hair, they should choose lighter-colored hair dyes and avoid dyeing their hair on foggy days.

2. The skin is most afraid of sunburn

The "enemy" that causes skin aging is precisely the sunlight that we cannot live without every day. Dermatologists say that ultraviolet rays not only make the skin rough and cause pigmentation, but also cause photodermatosis, aggravate freckles, chloasma, etc., and even induce cancer.

During the time when sunlight is strongest, you should avoid staying outdoors for too long. Before going out, apply sunscreen and wear a sun hat, parasol, etc. In addition, ensuring adequate sleep and eating more fruits and vegetables are also very important for skin care.

3. The wrist is most afraid of calcium deficiency in bones

According to orthopedic doctors, falls can easily lead to fractures in middle-aged and elderly people, with the most common fractures occurring in the wrists, hip joints, and lumbar spine. On the one hand, the wrist is at the end of the bone, and most people will use their wrists to support themselves when falling, which can easily lead to fractures. On the other hand, osteoporosis is more common among middle-aged and elderly people, and their bones are more brittle.

Therefore, when you fall, you should consciously learn to "roll down" like athletes or land on your buttocks first. Regardless of whether you feel pain when you fall, you should go to the hospital for an X-ray in time. In addition, it is very important to eat more dairy products, soy products, get more sun exposure, and supplement calcium.

4. Breasts are most afraid of bra discomfort

Experts say that women today are under great stress, have poor sleep, and have irregular work and rest schedules, which lead to endocrine disorders and become the cause of breast diseases. This is the inherent pressure on the breasts.

Studies have found that wearing a bra for too long (more than 10 hours a day) is an external stress that can lead to a significantly increased risk of breast disease. It is recommended that women should combine work and rest and eat less high-oil and high-fat foods. Be sure to take off your bra when you go to bed, and give your breasts a day off on weekends by not wearing a bra.

5. The stomach is most afraid of cold food

To maintain a healthy stomach, you should pay attention to the stomach's 5 "good friends": eat more warm and juicy food; eat three meals at regular times and in regular amounts; chew slowly; massage your abdomen frequently; and maintain a good mood.

6. The liver is most afraid of excessive drinking

90% of alcohol is metabolized in the liver, and being drunk once is equivalent to getting hepatitis. Experts say that long-term excessive drinking can lead to alcoholic fatty liver, alcoholic hepatitis, and even cirrhosis and liver cancer.

It is recommended not to drink on an empty stomach and to drink less in one gulp. The alcohol content for men should be less than 40 grams per day, and for women it should be less than 20 grams. The calculation method of alcohol is: the amount of alcohol consumed (ml) multiplied by the alcohol content, and then multiplied by 0.8 grams.

7. The reproductive system is most afraid of bad habits

Women are prone to gynecological diseases such as vaginitis, while men are always troubled by prostate diseases. Both diseases are closely related to lifestyle habits.

Gynecologists say that many gynecological diseases such as vaginitis are related to sitting for long periods of time and not changing underwear frequently. It is recommended that female friends must choose loose and breathable cotton underwear, wash the vulva with clean water every day, and use vulva cleaning lotion in moderation, but not every day.

Men's experts remind male friends that sitting for long periods of time directly compresses the prostate, which can cause damage to it that is even less than smoking and drinking. Therefore, you should stand up and move around for 10 minutes every hour you sit, exercise regularly, avoid overeating, quit smoking and limit alcohol consumption.

8. The most feared thing about the knees is overusing them

When walking, the pressure on the knees is several times that when they are relaxed. Experts say that many middle-aged and elderly people walk for one or two hours at a time, which can easily lead to bone hyperplasia, thinning of the meniscus, and damage to the cartilage, causing pain and swelling.

It is recommended to walk for forty to fifty minutes every day, taking 70 to 80 steps per minute, and each step is 50 to 60 centimeters. If you feel that the amount of exercise is not enough, you can swim, practice Tai Chi, etc.

9. The most feared thing about legs is that they are not moving for a long time.

Experts say that if you don't exercise actively from the age of 20, you may lose 5% of your muscle tissue every 10 years. Some elderly people don't like to walk around, which can lead to decreased muscle elasticity at best and affect blood circulation at worst.

You might as well practice leg shaking often: sit upright on a hard chair with your calves perpendicular to the chair, and shake your legs back and forth, left up and right down or right up and left down, for 3-5 minutes each time. You can also gently tap the front and sides of your thighs while shaking.

10. Feet are most afraid of shoes that don’t fit

Wearing improper shoes can cause great harm to your feet. Experts say that high heels are the most "destructive" and can cause hallux valgus, forefoot pain and other problems, and can also affect the pelvis, ankles, knees and hip joints, spine, etc.

The most important thing for middle-aged and elderly friends to avoid is wearing shoes that do not fit the toes. When choosing shoes, they must buy shoes that can cover the heels and have soles with moderate hardness. For people with flat feet, who walk with their feet turned inward or outward, or who have bow legs, it is recommended that they go to a rehabilitation institution to buy insoles, orthotics, etc.
