Immunity, as the body's own defense mechanism, is the key to fighting disease and maintaining health. It is like an invisible army, always guarding our body against the invasion of external viruses and bacteria.
So, how can you tell if a person's immunity is strong? In fact, people with strong immunity tend to share some common characteristics.
There are 6 characteristics of the body
Or it means that the body's immunity is not bad
1. The wound heals quickly
If your wound heals quickly, it usually means that your immune system is functioning well. A strong immune system is able to quickly recognize and destroy pathogens, thus promoting wound healing.
2. It is not easy to catch a cold
People with strong immunity are usually less susceptible to colds, and even occasional colds can have relatively mild symptoms. This is because a strong immune system is effective against viruses and bacteria.
3. Good mental state
Strong immunity helps to maintain a good mental state. You may feel more energetic, emotionally stable, and better able to cope with the stresses in your life.
4. Stable gastrointestinal function
Stable gastrointestinal function is an important manifestation of strong immunity. A strong immune system is able to protect the intestines from pathogens, thus maintaining normal digestion and absorption functions.
5. Stable weight
Stable weight is usually a sign of strong immunity. A strong immune system helps regulate the body's metabolic processes, which leads to the maintenance of a healthy weight.
6. High sleep quality
A good night's sleep is an important feature of a strong immune system. A strong immune system helps regulate the body's biological clock, which improves sleep quality.
What is the cause of low immunity
1. Malnutrition:
The body needs enough nutrients to support the function of the immune system. Deficiencies in vitamins and minerals, such as vitamin C, vitamin D, zinc, and iron, can lead to weakened immunity.
2. Lack of sleep:
Sleep is a critical time for the body to recover and the immune system to rebuild. Long-term sleep deprivation can weaken the activity of immune cells and increase the risk of infection.
3. Chronic stress:
A prolonged state of stress releases stress hormones, such as cortisol, which suppress the function of the immune system and reduce the body's resistance to disease.
4. Bad living habits:
Bad lifestyle habits such as smoking, excessive alcohol consumption, and lack of exercise can damage the immune system and lower the body's defenses.
5. Age factor:
As we age, the function of the immune system gradually declines. Older people may not have as many and active immune cells as younger people, so they are more susceptible to contracting diseases.
Low immunity
What to eat to boost immunity
1. Foods rich in vitamin C:
Vitamin C helps boost the activity of immune cells, such as citrus fruits, strawberries, kiwifruit, and tomatoes.
2. Foods rich in vitamin E:
Vitamin E is a powerful antioxidant that helps protect cells from damage. Nuts, seeds, spinach, and broccoli are all good sources of vitamin E.
3. Zinc-rich foods:
Zinc is essential for maintaining the normal function of the immune system. Oysters, red meat, legumes, and whole grains are rich sources of zinc.
4. Foods rich in Omega-3 fatty acids:
Omega-3 fatty acids have anti-inflammatory effects and help regulate the immune system. Salmon, tuna, flaxseed, and walnuts are good sources of Omega-3s.
5. Probiotic-rich foods:
Probiotics help maintain gut health, which is closely linked to the immune system. Probiotics are found in yogurt, fermented foods such as kimchi and sauerkraut.
6. Antioxidant-rich foods:
Antioxidants can help reduce free radical damage to cells, thereby supporting the immune system. Blueberries, cherries, carrots, and dark green vegetables are rich in antioxidants.
