What is low immunity?
Low immunity refers to a state in which the body's immune system is weakened and unable to effectively resist the invasion of pathogens or remove abnormal cells in the body. This state may lead to frequent infections, slow wound healing, or increased risk of chronic disease. The following is a detailed analysis of low immunity, including definition, symptoms, causes and recent hot related topics.
1. Main manifestations of low immunity
| Symptom type | Specific performance |
|---|---|
| Increased frequency of infections | More than 4 colds per year, recurring mouth ulcers, skin infections, etc. |
| Prolonged disease course | A common cold lasts for more than 2 weeks and a wound takes more than 1 month to heal |
| systemic symptoms | Persistent fatigue, loss of appetite, and unexplained weight loss |
2. Recent hot topics related to immunity (last 10 days)
| Ranking | Topic content | Discussion popularity |
|---|---|---|
| 1 | The impact of the new coronavirus variant JN.1 on immunocompromised people | Search volume across the entire network exceeds 5 million |
| 2 | How to boost immunity during winter flu season | Social media interactions reached 1.2 million |
| 3 | New findings on the relationship between intestinal flora and immune function | Professional platform citations: 8,000+ |
3. Main causes of low immunity
1.physiological factors: Age (infants/elderly people), hormonal changes during pregnancy, hereditary immunodeficiency diseases.
2.disease factors: Chronic diseases such as AIDS, diabetes, and cancer can directly weaken the function of the immune system.
3.lifestyle:
| bad habits | Impact on immunity |
|---|---|
| Stay up late for a long time | Reduce immune cell production |
| excessive drinking | Destroy the intestinal immune barrier |
| lack of exercise | Reduce immune cell activity |
4. Scientific methods to improve immunity
1.Nutritional supplements: Ensure the intake of key nutrients such as protein, vitamin A/C/D, zinc. Recent research shows that daily vitamin D supplementation can reduce the risk of respiratory infections by 12%.
2.Exercise advice: 150 minutes of moderate-intensity exercise per week can improve immune cell circulation efficiency. Be careful to avoid immune suppression caused by excessive exercise.
3.mental health: Chronic stress can increase cortisol levels, directly suppressing immune system function. Stress reduction methods such as mindfulness meditation have become a hot topic recently.
5. Special circumstances that require vigilance
If the following situations occur, it is recommended to seek medical examination immediately:
| • Pneumonia occurs more than 2 times within a year | • Low-grade fever that lasts for more than 1 month |
| • Recurrent deep organ infections | • Family history of immunodeficiency |
Recently, with the high incidence of respiratory diseases in winter, hospitals in many places have reported a 30% increase in the number of visits for immunocompromised patients. Experts recommend that key groups should receive influenza vaccination in advance and maintain indoor air circulation.
Immunity is the cornerstone of health. Through scientific understanding and active management, immune function can be effectively improved. If you suspect that you have immunity problems, it is recommended to conduct professional immune indicator testing (such as lymphocyte subpopulation analysis) instead of blindly using health products.
