Steam inhalation keeps the mucous membranes moist. Adding salt or essential oils such as eucalyptus and rosemary enhances the benefits. Steam can be obtained through a steamer, warm shower, or humidifier, which provides relief and promotes healing.

Mint tea:
Menthol in peppermint tea has anti-inflammatory, antiviral and antibacterial properties that help reduce phlegm and relieve cold and cough symptoms. Drinking mint tea supports the body’s defense against colds and helps in the healing process.

ginger:
Ginger, with its antiviral and antibacterial properties, helps dry up excess phlegm and make it easier to get rid of. Ginger tea is a soothing option to relieve symptoms associated with respiratory congestion.

Keep your head up:
Elevating the head helps the natural drainage of phlegm and mucus from the nose to the bottom of the throat, preventing its accumulation.

Additional Tips:

Avoid suppressing a cough: Coughing helps remove secretions from the lungs and throat, so it is better to let it go rather than suppress it.
Limit alcohol and caffeine intake: These substances can lead to dehydration and hinder the healing process.
Avoid smoking and secondhand smoke: Smoking worsens phlegm production, while exposure to secondhand smoke can have similar effects.
Watch your diet: Refrain from eating foods that cause acid reflux, dairy products, and irritants such as chemicals and pollutants, as they contribute to increased phlegm.
Handle nose blowing with care: Avoid blowing forcefully to prevent pain and possible infection.
