The strength of the immune system is not established in a day. It is relatively weak in childhood, gradually becomes stronger as one grows up, and begins to decline again in middle-aged and elderly people. Therefore, immunity changes with age and aging.
It does not mean that you will have strong immunity as you age. You also need other material assistance and coordination, such as diet, vitamin and protein and other nutrients that are indispensable.
Factors such as dieting, staying up late, smoking and drinking, not keeping warm, not liking exercise, etc. will all affect immunity and lead to a decline in immunity. If you can maintain good habits and live a regular life, your immune system will not be easily destroyed.
01
What role does the human immune system play in the human body?
immune means defense, and system means human organs and tissues. The immune system is also called the defense system, which is mainly composed of lymphocytes and immune cells .
The function of the immune system is mainly to defend and kill the invasion of viruses germs. For example, when the influenza virus arrives, the immune cells are in a defensive state, lymphoid tissue sees whether the virus will disturb the body, and the lymphatic organs sterilize and stabilize the internal environment.
Viral infection shows that immunity is low, and immune cells have not taken preventive measures. After the age of 30, immunity gradually declines. Flu, colds, wound inflammation, and anything that is easily invaded by viruses are all caused by low immunity.
02
People with strong immunity usually have 6 characteristics. How many do you have?
Barely get sick
Strong immunity can block viruses and bacteria. If immunity is reduced, viruses and bacteria will take the opportunity to enter the human body and cause inflammation, which in turn can cause diseases, such as colds, fevers and coughs.
If you often get sick, it may be that your body is reminding you that you need to improve your immunity. Otherwise, you will continue to have minor illnesses, and over time, the possibility of cancer will also increase.
Drink enough water
Most of the body is composed of water, so we should drink more water every day, which can improve the body's mental metabolism, accelerate the discharge of toxins and garbage, and promote blood circulation .
Drinking more water can also activate immune cell activity and improve immunity. When viruses and bacteria invade the human body, it can better protect the body. Adults should drink 2000~2500 ml of water every day.
Wounds heal faster
In life, it is inevitable that there will be bumps and bruises, which will lead to wounds on the body. Generally speaking, small wounds on the body will heal and scab in as little as two or three days, and in as many as 5 to 7 days.
If a wound is formed during surgery, people with strong immunity will heal the wound faster and are less prone to infection. However, those with low immunity will be prone to infection if they cannot properly protect and care for the wound, causing the wound to not heal for a long time.
Love sports
Proper daily exercise can promote the detoxification of lymphocytes , enhance immune function , and activate the body's antioxidant . It can not only improve immunity, but also have a beauty and beauty effect.
During exercise, the brain will release more dopamine , and the mood will become happy, so those with strong immunity generally love exercise.
You don’t always feel tired, and your mental state is better.
People with strong immunity can function normally, have a better mental state, do not feel tired, and have better study and work efficiency. However, those with low immunity always feel physically tired and have a poor mental state.
Good Appetite
When immunity declines, appetite will become worse and loss of appetite will occur. Because of loss of appetite, insufficient nutrition cannot be supplemented, and the immune system will also be affected.
03
What should you do to improve your immunity?
Ensure adequate sleep
If you want to improve your immunity, you must have adequate sleep every day. It is best to ensure 7 to 9 hours of sleep every day. Go to bed early and get up early and do not stay up late. The mental state of the whole person will be different.
Eat healthily
If you want to be healthy and have a strong immune system, you must supplement your body with enough nutrients, including protein, sugar, fat, minerals, vitamins, etc., so you should eat healthier every day, eat more fruits and vegetables, drink more water, eat more red meat, and eat less white meat.
Keep a good mood
Bad mood will affect the activation and development of immunity, which is not conducive to physical health. Therefore, if you want to improve immunity, you must maintain a good mood and avoid mental exhaustion.
Drink more water
Drinking more warm water can replenish the body with water, promote metabolism, and improve immunity. If the body is short of water, not only will the mouth feel dry, but it is also detrimental to the health of the internal organs. In addition to drinking boiled water, you can also drink a little light tea, but do not drink coffee, liquor, sugary drinks, etc.
