How does a cold affect peak flow?
- Inflammation: A cold can cause inflammation and swelling in the airways, which can narrow them and make it harder for air to flow through.
- Mucus production: A cold can also cause the production of excess mucus, which can further obstruct the airways.
- Coughing and sneezing: Coughing and sneezing can also reduce peak flow by irrita.ting the airways and causing them to become inflamed and swollen.
- Other symptoms: Other cold symptoms, such as nasal congestion and fatigue, can also contribute to reduced peak flow because they can make it difficult to take deep breaths.
As a result of these factors, colds can cause a significant decrease in peak flow, which can make it difficult for people with asthma or other respiratory problems to breathe.
Here are some things you can do to help improve your peak flow during a cold:
- Use a humidifier. Adding moisture to the air can help loosen mucus and make it easier to breathe.
- Drink plenty of fluids. Staying hydrated can help thin mucus and make it easier to expel.
- Use saline nasal spray. Saline nasal spray can help flush out mucus and reduce congestion.
- Take over-the-counter medications. Over-the-counter medications, such as decongestants and expectorants, can help relieve cold symptoms and improve peak flow.
- Avoid exposure to allergens and irritants. Allergens and irritants, such as cigarette smoke and pollution, can worsen cold symptoms and reduce peak flow.
- Get plenty of rest. Resting can help your body fight off the cold and reduce your symptoms.
If your peak flow drops below your personal best, it is important to see your doctor. They may recommend additional treatments to help you manage your cold and improve your peak flow.
