Is there any way to avoid COPD exacerbation?

Tips to help avoid COPD exacerbation:
• Take medicines as recommended by the treating physician.
• See the physician at regular intervals, even if one is feeling fine.
• Get flu shot every year.
• Avoid respiratory tract infections as far as possible.
• Wash hands often for 20 seconds with warm water and mild soap. If washing hands is not possible, use sanitizer.
• Avoid touching mouth, eyes, and nose in public to prevent germs from entering one's body.
• Stay away from crowds, especially during cold and flu season.
• Get plenty of sleep.
• Drink plenty of water. Thick sticky mucus is more likely to get stuck in one's lungs and cause problems.
