Winter Nosebleeds: Causes, Prevention Tips, and When to See a Doctor

Why Nosebleeds Increase in Winter

• Low humidity: Cold outdoor air holds less moisture; indoor heating further dries the air, dehydrating nasal mucosa.
• Indoor heating: Forced-air systems reduce indoor humidity to 10-20%, causing nasal crusting and cracking.
• Viral infections: Colds and flu cause nasal inflammation, congestion, and frequent nose blowing.
• Nose blowing: Forceful blowing ruptures fragile vessels in dry mucosa.
• Trauma: Dry, cracked skin around nostrils bleeds easily with minor trauma.
• Medications: Blood thinners (warfarin, aspirin), NSAIDs, and nasal steroids increase bleeding tendency.
• Underlying conditions: Deviated septum, nasal polyps, hereditary hemorrhagic telangiectasia, bleeding disorders.

Prevention Strategies

• Humidifier: Maintain indoor humidity at 30-50%.
• Saline nasal spray/gel: Use several times daily to moisturize mucosa.
• Petroleum jelly or antibiotic ointment: Apply gently inside nostrils at bedtime.
• Hydration: Drink adequate fluids.
• Gentle nose blowing: Blow one nostril at a time, gently.
• Avoid nose picking and irritants (smoke, chemical fumes).

How to Stop a Nosebleed

1. Sit upright, lean slightly forward (not back).
2. Pinch the soft part of the nose (just below the bony bridge) firmly for 10-15 minutes without releasing.
3. Apply ice pack to bridge of nose.
4. If bleeding persists >20 minutes, seek medical care.

When to See a Doctor

• Frequent nosebleeds (>1/week)
• Bleeding lasts >20 minutes despite pressure
• Large volume blood loss
• On blood thinners or have bleeding disorder
• Associated with facial trauma
