Self-care guide
Nasal congestion
A blocked or stuffy nose caused by swelling of the nasal lining, mucus, or both, commonly during a viral cold, allergies, or sinus inflammation.
Step 1 · First-line care
What to do first
For uncomplicated short-term congestion, use fluids, rest, a clean humidifier or cool-mist vaporizer, and saline nasal spray or drops. These measures can improve comfort while the underlying illness resolves. Menthol may make airflow feel easier without physically opening the nasal airway. Do not confuse symptom sensation with treatment of the underlying cause.
Step 2 · Safety
When to get medical help
Seek prompt medical assessment if nasal congestion or cold symptoms are accompanied by trouble breathing or unusually fast breathing.
Get medical help if arrange medical assessment for severe facial pain or headache with sinus symptoms, worsening after initial improvement, symptoms lasting more than 10 days without improvement, or prolonged fever.
Extra caution: Children, pregnancy, asthma or other chronic lung disease, recurrent sinus disease, and people using multiple cold medicines need product-specific review. Avoid direct intranasal use of undiluted essential oils. Young children should not inhale steam from bowls of hot water because of burn risk.
Step 3 · Optional ingredient support
For relief now
These options have been reviewed for evidence and key safety concerns.
Menthol
Short-term subjective relief of the sensation of nasal blockage during a common cold using a menthol preparation comparable to studied products.
How it is used: If using menthol, choose a labeled lozenge or other product intended for that route and follow its directions. Do not convert these studies into a claim for peppermint tea, homemade essential-oil inhalation, or drops placed directly in the nose.
What does this evidence mean?
Small controlled studies suggest menthol can make nasal airflow feel easier during a cold, but objective measurements show it does not reliably reduce nasal airway resistance. The benefit is sensory rather than true decongestion.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
For ongoing support
These options are better suited to regular or longer-term use than to quick symptom relief.
