Why Do You Get More Nosebleeds in Winter? Doctors Explain the Common Triggers and How to Prevent Them

A sudden nosebleed can be alarming, especially when it happens without an obvious reason. However, some people experience nosebleeds more frequently during winter because cold weather and dry air can affect the delicate lining inside the nose.

Although most nosebleeds are harmless and stop on their own, frequent episodes may indicate irritation or an underlying health problem. Understanding the common triggers and knowing how to manage a nosebleed can help prevent unnecessary discomfort during the colder months.
For the same, we spoke to Dr (Major) Rajesh Bhardwaj, Consultant, MedFirst ENT Centre, New Delhi and Dr Girish Anand M S, Consultant - ENT Surgery at Aster CMI Hospital, Bangalore. Keep reading to know their insights.

Why Are Nosebleeds More Common In Winter?

The inside of the nose contains many tiny blood vessels close to the surface. These vessels help warm and moisten the air we breathe before it reaches the lungs. However, their position also makes them vulnerable to irritation and bleeding.

Cold, Dry Air Dries Out The Nasal Lining

During winter, outdoor air tends to be colder and can be dry. According to a study published in the journal 'Acta Oto-Laryngologica', when the nasal lining loses moisture, it may become dry, irritated, and cracked. These small cracks can damage the tiny blood vessels, causing them to bleed.

People with naturally dry skin, sensitive nasal passages, or frequent nasal irritation may be more vulnerable to winter nosebleeds.

Room Heaters Reduce Indoor Humidity

Spending long hours in heated rooms can worsen the problem. Heating systems may reduce indoor humidity, allowing the nasal lining to dry out further.

This can make the inside of the nose more sensitive and increase the likelihood of bleeding, particularly in people who already experience nasal dryness.

Colds, Coughs And Allergies Cause Irritation

Winter often brings an increase in respiratory infections, including colds. A blocked or runny nose can lead to frequent nose-blowing, sneezing, and rubbing, all of which may irritate the delicate nasal lining.

People with allergies may also experience nasal inflammation and irritation due to dust and other airborne particles. Repeated rubbing or forceful nose-blowing can damage small blood vessels and trigger bleeding.

Certain Medicines Can Increase The Risk

According to a report published in the Australian Journal of Otolaryngology, some medicines can make nosebleeds more likely. Blood-thinning medicines may increase bleeding, while nasal sprays, particularly those used incorrectly or excessively, can irritate the nasal lining.

People taking prescribed blood thinners should not stop their medication without consulting their doctor. Those experiencing repeated nosebleeds should seek medical advice to review possible causes.

Are Winter Nosebleeds a Sign Of High Blood Pressure?

• Most nosebleeds occur because of local irritation or damage to blood vessels inside the nose. High blood pressure is not usually the direct cause of a nosebleed, although it may be associated with more difficult-to-control bleeding in some cases.
• People with bleeding disorders or those taking blood-thinning medicines may also experience prolonged or recurrent episodes. Frequent nosebleeds should not be ignored, particularly when they occur without an obvious trigger.

How Can You Prevent Nosebleeds During Winter?

A few simple measures can help keep the nasal lining moist and reduce irritation.

• Use a saline nasal spray: It helps moisturise the inside of the nose and ease dryness.
• Try a water-based nasal gel: A suitable nasal moisturising gel can help protect dry nasal passages.
• Maintain indoor humidity: Using a humidifier may help prevent indoor air from becoming excessively dry. Clean it regularly according to the manufacturer's instructions.
• Avoid picking your nose: Picking or rubbing can damage delicate blood vessels.
• Blow your nose gently: Avoid forceful blowing, particularly when you have a cold or blocked nose.
• Manage allergies: Seek appropriate treatment if allergies are causing persistent sneezing, itching, or nasal irritation.

What Should You Do If You Get A Nosebleed?

If your nose starts bleeding, sit upright and lean slightly forward. Pinch the soft part of your nose, just above the nostrils, firmly for 10-15 minutes without releasing the pressure to check whether the bleeding has stopped. Breathe through your mouth during this time.

Avoid tilting your head backwards, as this can cause blood to flow down your throat.

Seek urgent medical attention if the bleeding is heavy, causes weakness or breathing difficulty, follows a serious injury, or continues after 20 minutes of firm, uninterrupted pressure. If nosebleeds keep returning, consult a doctor to identify the underlying cause.

Final Word

Winter nosebleeds are often linked to dryness and irritation rather than a serious illness. Keeping the nasal lining moist, avoiding unnecessary irritation, and knowing the correct first-aid steps can help reduce their frequency and manage them safely.
