You don't like making friends. Research shows that people who have less contact with others have hormones that cause anxiety in their brains, and they are more likely to get sick than people with strong social skills. A study of 276 people aged from 18 to 55 found that people with six friends were four times more resistant to cold viruses. Short conversations, phone calls, emails and text messages can build your defense system.
Lack of sleep. Researchers at the University of Chicago found that men who slept only four hours a night for a week had half the flu antibody in their blood as men who slept 7.5 to 8.5 hours.
Negative emotions. When pessimists correctly handle the misfortunes in life, they have less psychological pressure and are healthier. A study by UCLA found that students who are optimistic about college life have significantly more immune-promoting cells in physical examination than their pessimistic peers. Try to say "I am so lucky" to yourself every day to cultivate a sense of luck. Sharing diet and daily happiness with family can also help to eliminate pessimism.
Husband and wife are always sarcastic. It is found that couples talk about difficult marriage problems calmly 15 minutes, and their blood pressure, heart rate and immune-related white blood cells change as well as moderate exercise. It was found that those couples who sarcastically, ridiculed or even despised each other had fewer antiviral cells and higher levels of stress hormones, and the cure rate was 40%.
It is found that constructive discussion on marriage between husband and wife can improve blood pressure, heart rate, white blood cell count and immunity. Experts advise not to keep your problems to yourself.
The study found that inactive office workers are twice as likely to call in sick within four months as those who often walk quickly. Experts suggest doing 30 minutes of aerobic exercise every day, such as brisk walking, to help improve the white blood cell count and immune system function.
