Always feel tired
You are often tired, yawn all day, feel no energy, no interest in doing anything. Even if you adjust, you can never recover. At this time, be alert that your immunity is decreasing.
Colds all year round
Many people really pay special attention to maintaining and taking care of their bodies, such as keeping warm in time when the weather changes and rarely going out. Even so, they still accidentally catch a cold.
A person with a good immune system can recover from a cold in about 4 or 5 days, even without medication, without any major problems. But if the immune system is weak, even a small cold will make the condition worse and take longer to heal.
Always upset stomach
Many people may have stomach aches and diarrhea if they eat carelessly. However, intestinal health is directly related to immunity. If a person always has intestinal problems and often has stomach aches and diarrhea, it shows that the immune system has weakened.
The intestine is closely related to the body's immunity. 70% of the human body's IgA immunoglobulin is located in the intestine, and more than 95% of infectious diseases are related to the digestive tract.
Slow wound healing
Wounds in people with good immunity can often heal quickly, because the immune mechanism quickly eliminates other pathogenic microorganisms that attack the wound, thereby promoting faster wound healing. On the contrary, when immunity is too weak, the wound will also heal slowly.
For example, diabetic feet often take a long time to heal because the disease causes a decrease in immunity. After the immune system is reduced, different types of microorganisms will attack the body, causing even a small wound to take time to heal.
Poor sleep quality
Sleep and immunity complement each other. If a person has good sleep quality, his or her immunity will also be very good. Conversely, when a person sleeps poorly, immunity will also decrease.
How to improve immunity?
Maintaining good living habits is the most important way to improve immunity. People should exercise, get more sunlight, maintain a happy mood, laugh more, and maintain adequate sleep and eat a balanced diet.
