In a lot of cases, a dry cough is the result of a viral infection, which sadly isn't always possible to prevent. The best form of defence is to ensure your immune system is kept strong and healthy. This can be aided by changes to your lifestyle that promote healthy living.
Lifestyle changes that will help keep your immune system in tiptop condition include
- Regular exercise.
- A healthy diet rich in fresh fruit and vegetables.
- Drinking lots of fluids (especially water).
- Plenty of sleep (approximately between 7-9 hours each night).
- Avoided anxiety & stress.
- Cutting down on alcohol intake.
- Quitting smoking.
If the dry cough is brought on by allergies, try to avoid exposure when possible. Otherwise taking an appropriate antihistamine can help prevent a reaction. If an asthma sufferer, ensuring the condition is well controlled will help prevent flare-ups, which could likely lead to a dry cough.
If you find yourself suffering from either a persistent or recurrent dry cough, it is recommended to visit your GP, who will be able to identify or rule out any underlying cause.
