Self-Care at Home

1. Drink Lots of Fluids

Drink adequate amounts of fluids so that your body can function properly. You should drink 250 ml (8 oz.) of fluid every 1-2 hours. Keeping yourself hydrated will help loosen congestion. Your fluid intake should be in the form of water, clear broth, and warm water with lemon and honey or diluted sports drinks. Avoid consuming caffeine or alcohol-containing drinks as they may lead to dehydration.

2. Take Adequate Rest

Strive to sleep as much as possible. You should get at least 7 hours of sleep at night as sleep helps in maintaining strong immunity. If you are not able to sleep at night due to illness, you should still rest by lying down.

When you breathe in moist, warm air, the mucus in the airways will be loosened and it will be easy for you to breathe and the severity of your cough will be reduced. Make sure to clean the humidifier regularly. If you don’t clean it fungi and bacteria can breed inside the container of water and get released in the air. This can further complicate your bronchitis.

You can also inhale steam by sitting in a closed bathroom with hot water flowing from the shower for half an hour. The steam will work in a similar manner as the vapor generated from the humidifier.
