10 bad habits that damage your immune system

Some people are strong and healthy, while others are prone to illness. This is due to different immune systems. Let’s take a look at the scientifically proven “10 habits that damage your immune system.”

1. Lack of sleep.

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

2. Suppress your 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.

3. 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. The recommended daily water intake is 40 ml of water per kilogram of body weight, and children need to drink more water.

4. Passive smoking.

Passive smoking is as harmful to overall health as smoking and reduces immunity. According to statistics, about 3,000 Americans die from lung cancer each year due to inhaling secondhand smoke.

5. Abuse of antibiotics.

The misuse of antibiotics may destroy the innate immunity of the intestine, which is also the cause of antibiotic-resistant bacterial infections.

6. Use a car to travel.

The study found that people who drive and are not physically active are twice as likely to take sick leave over a four-month period as those who walk briskly. Experts recommend that doing aerobic exercise such as brisk walking for 30 minutes a day can help improve white blood cell count and improve immune system function.

7. Small social circle.

Studies have found that the smaller a person's social circle is, the more likely they are to get sick. Among adults aged 18-55, those with at least six friends are four times more likely to resist colds than those with fewer friends. Experts suggest that keeping in touch with friends frequently and sending text messages to friends when you are busy is a new way to prevent colds.

8. The couple is cold to each other.

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.

9. There is a lack of singing in life.

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

10. 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.
