One common observation is that nosebleeds tend to occur more often during the summer months. Here’s why they happen and why they increase in summer.
What Causes Nosebleeds?
There are several possible reasons, and identifying the underlying cause is important for effective management. Common causes include:
Dry air: Can irritate and dry out the nasal lining, causing cracks that make bleeding more likely.
Trauma: Picking the nose, forceful blowing, or a direct injury can rupture blood vessels in the nose and trigger bleeding.
Allergies: Can inflame the nasal lining, making it more prone to bleeding.
Infections: Conditions like sinusitis or colds irritate and inflame the nasal lining, leading to bleeding.
Medical conditions: High blood pressure, blood clotting disorders, and tumors can also cause nosebleeds.
Why Nosebleeds Are More Common in Summer
While they can happen any time of year, the summer season often sees a rise due to:
Hot weather: Increases dehydration and dries out nasal membranes, making them more fragile.
Humidity: High humidity can cause nasal tissues to swell, making them more injury-prone.
Outdoor activities: Summer sports like basketball, football, and soccer raise the risk of injuries that cause nosebleeds.
Swimming: Chlorine and other pool chemicals can irritate the nasal lining.
Seasonal allergies: Common in summer, and nasal decongestants or antihistamines used to treat them may contribute to dryness and bleeding.
How to Prevent Nosebleeds
Keep nasal passages moist: Use a humidifier or saline spray to prevent dryness.
Avoid irritants: Stay away from cigarette smoke, polluted air, and chemical fumes.
Don’t pick your nose: Reduces the risk of injuring delicate nasal tissues.
