What causes lack of immunity?

When changing seasons, the temperature is unstable at this time, and the temperature difference between day and night is large, which is easy to cause diseases such as colds. In fact, sometimes you get sick because your immunity is low and bacteria are more likely to invade your body. So what is the reason for low immunity? What shows that immunity is low?

One is psychological anxiety or negative pessimism.

Anxiety and pessimism will adversely affect the autonomic nervous system, thus affecting the endocrine system and immune system, leading to a sharp decline in human immunity for a period of time.

Some people are prone to symptoms of oral ulcers. In fact, a bad mood affects immunity. Long-term anxiety is easy for germs to take advantage of it.

If you stay in anxiety and pessimism for a long time, it may do more harm to the human body.

Second, the body is overworked.

The mechanism of immunity decline caused by overwork is the same as the former, which affects autonomic nervous system, and then affects endocrine system and immune system. Improper weight loss, lack of rest, long-term heavy physical labor, overeating, etc. It will cause the human body to overload and lead to decreased immunity.

Third, there is not enough exercise.

Cultivating the habit of daily exercise can not only improve the function of human organs, but also promote the orderly circulation system, thus improving immunity.

However, lack of exercise will often make various systems of the human body in a state of relaxation. Once germs "invade", various functions cannot be quickly mobilized and put into operation.

People who don't exercise or seldom exercise are more likely to get flu and other common infectious diseases than those who exercise regularly.

The fourth is the natural aging of the human body.

With the growth of age, people recover slowly after illness and are more likely to catch common infectious diseases such as colds. This is because the functions of human organs and so on can not be fully exerted after natural aging, or can not reach the level of youth, thus causing the decline of human immunity.

A sign of low immunity

Often feel tired.

I often feel tired for no reason, sometimes I do nothing, but my body feels too tired. I don't have the strength to do anything. The whole person looks lifeless.

I went to the hospital when I was wondering if there was something wrong with my body, and I couldn't find any symptoms. Then I went home to rest for a while before I could continue to work, but I began to get tired in a few days.

Keep catching a cold

A cold has become your daily routine. The weather gets colder and colder. Sneezing before adding clothes will take a long time to cure a cold.

Wounds are susceptible to infection.

After a certain part of the body is accidentally scratched, the wound will be red, swollen and even purulent within a few days. Normal people will recover soon, but you have to wait a long time.

Or a part of you, such as a sore and itchy boil on your ass, will grow on your head in a few days.

It is prone to gastrointestinal diseases.

Eating an ordinary dish in a restaurant outside, others are safe and sound, and you vomit and diarrhea, which are all manifestations of low immunity.

Ten kinds of people who are prone to low immunity

The circle of communication is too narrow

Friendship can enhance immunity. The fewer friends a person makes, the more likely he is to get sick, and even his life span will be greatly affected.

I owe a "sleep debt" on weekdays

Frequent deduction of sleep time will reduce the number of immune cells produced by the body.

People who sleep 7-8 hours a day and those who sleep only 4 hours a day have only 50% influenza antibodies in their blood.

Always think the worst of everything.

When pessimists take a positive view of the misfortunes in life, their physical condition is significantly improved.

There's something in my stomach.

Couples who like to discuss problems will reduce their blood pressure and heart rate, while the number of immune-related white blood cells will increase, which is similar to the benefits of moderate exercise.

Live under heavy pressure

People are most likely to get sick within one year after their spouse dies. Similarly, a job that makes you fidgety will do deep harm to your immunity. Traveling by bike, taking yoga classes and learning to cook by yourself are all good ways to relieve stress.

Personal belongings are incomplete.

When signing, I found that there was no pen in my pocket, but I borrowed someone else's or used public goods, which provided an opportunity for the spread of the virus.

Go out often by car, don't walk.

There are more and more car owners, and about 25% people have lost the habit of walking.

People who drive around all day are twice as sick as those who like to walk. Do aerobic exercise for 30 minutes every day, and the immune system will work more efficiently.

Excessive dependence on antibiotics

Taking antibiotics as soon as cold symptoms appear will only make the virus resistant and lead to more serious infection.

Not easy to be teased.

Laughter can reduce the secretion of stress hormones and increase the number of immune cells. Watching a funny video during lunch break and sharing jokes or cartoons forwarded by friends are all ways to get happiness.

My friend is a heavy smoker.

It is not enough to quit smoking by yourself. Needless to say, the health effects of secondhand smoke.

Conclusion: Through this article, we know that the reason of low immunity may be psychological anxiety or negative pessimism, or it may be caused by physical overwork. We should strengthen exercise in life and ensure adequate sleep at the same time. Low immunity is easy to cause constant colds and wounds are easy to be infected, so we must pay attention to the problem of low immunity.
