What are the bad habits that destroy immunity

I have been feeling weak and powerless recently, sometimes even dizzy, and I can't do strenuous exercise at all, so I went to the hospital for a physical check-up. The doctor said that my immunity was decreased and prescribed a lot of medicine to improve my immunity. I want to know if human immunity can be destroyed by external conditions? What bad habits can damage immunity?

1. Lack of singing in life

Singing helps improve people's immunity. Scientists tested the choir members' blood before and after rehearsals and found that the singers had significantly increased levels of immunoglobulin A, a protein in their immune systems, and cortisol, an anti-stress hormone.

2. Misuse of antibiotics

The misuse of antibiotics will destroy the innate immunity of the intestines and cause greater harm to the patient's health. This is also what causes antibiotic-resistant bacterial infections.

3. Social Circle

The smaller a person's social circle, the more likely they are to get sick, a small study has found.

4. Lack of sleep

Lack of sleep can lead to a decrease in immunity and reduce the number of "killer cells" that fight germs. Compared with people who sleep 7.5 to 8.5 hours a night, people who only sleep 4 hours a night have 50% less antibodies against influenza in their bodies. ?

5. Suppressing emotions

Studies have found that when couples have constructive discussions about marital problems, they can help improve blood pressure, heart rate, white blood cell count, and boost immunity. Experts advise not to keep problems to yourself.

6. Don't like drinking water

Drinking enough water can keep the respiratory mucosa moist, making it difficult for cold viruses to multiply quickly and enhancing immunity.

7. Traveling by car

People who drive and are not physically active are twice as likely to take sick leave as those who walk briskly over a four-month period.

8. Passive smoking

According to statistics, about 3,000 Americans die from lung cancer every year due to inhaling secondhand smoke.

9. Lack of sense of humor

?Studies have found that watching funny videos for one hour can significantly improve immunity. Because laughter helps reduce stress hormones, increase or activate certain immune cells, and improve immunity.

10. The couple is cold

Skin touch is the lubricant between couples. When the bodies come into contact, the body temperature rises slightly, the heartbeat speeds up a little, and many sensors are released in the body, which can suppress depression and enhance the body's immunity.

The ten aspects introduced above are bad habits in people's lives that are extremely likely to damage the human body's immunity. Once the human body's immunity is damaged, the normal operation of many body functions will be hindered, and the body will feel uncomfortable. Therefore, we must change those bad habits and strengthen physical fitness training, otherwise it will be difficult to have a healthy body.
