There are two types of human immunity, innate immunity and acquired immunity, which protect the body from illness.
First, when a foreign substance invades the body, innate immunity attacks, and if it is still unsuccessful, acquired immunity works.
Vaccination and multiple illnesses can gradually strengthen your body because it strengthens your acquired immunity.
It firmly remembers the shape of the virus that has entered the body, and when it invades the body again, it attacks quickly and quickly expels it from the body.
The acquired immunity once learned by the body does not weaken unless there is a great deal of trouble, and it is very stable.
This acquired immunity is usually absent, but we will do our best to fight only when the virus invades the body.
Therefore, it is innate immunity that constantly looks around the body.
This is the immune system that your body has had since you were born. However, there are individual differences in work, and some people have strong immunity and others have weak immunity. It is this innate immunity that is also susceptible to stress and eating habits.
One of the things that support innate immunity is NK cells. NK cells constantly look around the body and play a role in attacking foreign substances as soon as they invade.
Did you know that about 5,000 cancer cell buds are born every day in the human body?
Even so, it does not develop cancer because these NK cells are always crushing their buds.
Although it is such an important NK cell, it actually has the property of being vulnerable to stress.
For example, sadness, impatience, anger, lack of sleep, and physical fatigue.
Playing sports makes you feel stronger, but the opposite is true. Excessive exercise can make you more likely to catch a cold.
In fact, colds are the number one illness that occurs during international sports competitions. Such strenuous exercise reduces immune function.
Sleep deprivation is the most important thing to watch out for in your daily life, if not strenuous exercise.
Sleep has the role of resting the body, relieving fatigue, and refreshing the brain. Even if you exercise hard, if you can get a good night's sleep and rest your body after that, your fatigue will recover.
On the other hand, it's best to stop exercising due to lack of sleep.
A good night's sleep makes you more tolerant of stress and allows you to shed light things. However, lack of sleep inevitably tends to pessimistically think about things.
If you do not tolerate stress, stress tends to accumulate, and you will not be able to sleep in that state. It's a vicious circle.
In such a case, do a light exercise without trying to take a rest. Of course, it's better to stop suddenly strenuous exercise.
Well, there are other ways to improve the immune system.
It is to condition the intestines.
Immune cells that are the basis of acquired immunity and innate immunity are gathered in the intestine.
Moreover, about 70% of them.
In other words, if you don't take good care of your intestines, your immunity will weaken.
If you have pimples, rough skin, constipation, depression, or somehow feeling unwell, your intestinal environment may be deteriorating.
The condition of the intestines is directly affected by what you eat. In other words, the best way to improve is to review your eating habits.
In addition to that, if you combine good sleep and moderate exercise, your autonomic nerves will naturally be adjusted and your immunity will improve.
