As you get older, your immune system tends to weaken. This means you might get sick more often and take longer to recover. The immune system is a complex network of cells, tissues, and organs that work together to defend your body against infections. Researchers are still trying to understand exactly why immunity decreases with age, but they do know that older adults generally don't respond as well to vaccines, are more likely to get sick, and recover more slowly from illnesses and injuries. There are several things you can do to keep your immune system strong as you age: 1. Stay on top of your health by managing chronic conditions like diabetes and arthritis. 2. Get enough sleep, at least 7 hours a night. 3. Reduce stress through relaxation techniques and hobbies. 4. Avoid close contact with sick people and wash your hands often. 5. Keep up with vaccinations. 6. Exercise regularly with moderate activities. 7. Eat a balanced diet rich in vitamins and minerals. 8. Avoid smoking, as it weakens your immune response. By following these steps, you can help maintain a healthier immune system as you age.
