Reasons that make the elderly susceptible to infection include decreased immune function, weakened respiratory and cardiovascular function, poor nutrition, and the effects of chronic diseases.
- Decreased Immune Function:
With aging, the elderly's immune system gradually weakens, weakening the body's resistance to pathogens. Exercise and good sleep can help strengthen the immune system.
- Decreased Respiratory Function:
The elderly's respiratory muscles weaken, the respiratory mucosa atrophies, and ciliary movement weakens, making them more susceptible to respiratory infections. Maintain good indoor air circulation and avoid smoking and exposure to harmful gases.
- Decreased Cardiovascular Function:
Decreased cardiovascular function can affect blood circulation and oxygen supply, impacting the function of various organs and increasing the risk of infection. It's important to control blood pressure and blood lipids and maintain a healthy lifestyle.
- Poor Nutrition:
The elderly may experience problems such as loss of appetite and decreased digestion and absorption, leading to insufficient nutrient intake and impacting their immune system. Maintain a balanced diet and consume foods rich in protein, vitamins, and minerals.
- Impact of Chronic Diseases:
Older adults often suffer from multiple chronic diseases, such as diabetes, hypertension, and heart disease. These conditions can weaken the body's immune system and make them more susceptible to infection. Chronic diseases should be treated proactively, with medications taken regularly and regular checkups.
Older adults should maintain good personal hygiene, wash their hands frequently, and avoid crowded places. Maintaining a positive and optimistic attitude will help boost their immune system. If symptoms of infection occur, seek medical attention promptly and follow the doctor's advice.
