Nosebleeds in Freediving: Causes and Treatments - Otolaryngology

Nosebleeds, particularly in the context of freediving, can be concerning and may arise from several causes related to the unique pressures and physiological changes experienced during the activity. Understanding the underlying mechanisms can help in both prevention and treatment.


Causes of Nosebleeds in Freediving
1. Barotrauma: When you dive, the pressure increases significantly. If you descend rapidly or do not equalize your ears and sinuses properly, the pressure can cause trauma to the delicate blood vessels in your nasal passages. This can lead to bleeding, especially when you ascend and the pressure decreases rapidly.

2. Dry Air and Dehydration: Freediving often occurs in environments where the air can be dry, particularly if you're diving in cold water. Dry air can dry out the mucous membranes in your nose, making them more susceptible to bleeding. Dehydration can exacerbate this condition.

3. Nasal Trauma: Physical trauma to the nose, whether from a fall, bump, or even the act of equalizing, can cause bleeding. If you are experiencing pain in the forehead area above the eyebrow, it could indicate that there is some form of trauma or pressure-related issue affecting the sinuses.

4. Sinus Issues: If you have underlying sinusitis or other sinus-related issues, the changes in pressure during diving can irritate the sinuses and lead to bleeding. This can also result in post-nasal drip, where blood drains down the throat, leading to the sensation of blood in the mouth.

5. Underlying Health Conditions: Conditions such as hypertension or clotting disorders can make you more prone to nosebleeds. If you have a history of such conditions, it’s essential to consult with a healthcare provider.


Treatment and Management
1. Immediate Care: If you experience a nosebleed while diving, the first step is to remain calm. Pinch your nostrils together and lean slightly forward to prevent blood from flowing down the back of your throat. Applying a cold compress to the nose can help constrict blood vessels and reduce bleeding.

2. Hydration: Ensure you are well-hydrated before and after diving. This can help keep the mucous membranes moist and less prone to bleeding.

3. Nasal Saline Sprays: Using saline nasal sprays can help keep your nasal passages moist, especially if you are diving in dry conditions.

4. Avoiding Irritants: Stay away from irritants such as smoke, strong odors, or allergens that can exacerbate nasal bleeding.

5. Consult a Specialist: Given your symptoms of persistent bleeding and forehead pain, it’s crucial to consult an ENT (Ear, Nose, and Throat) specialist. They can perform a thorough examination to rule out any serious underlying conditions, such as a deviated septum or chronic sinusitis, and provide targeted treatment.

6. Gradual Descent and Ascent: When freediving, practice slow and controlled descents and ascents. This can help your body adjust to pressure changes more effectively and reduce the risk of barotrauma.

7. Avoid Diving When Sick: If you have a cold, sinus infection, or any condition that affects your nasal passages, it’s advisable to avoid diving until you have fully recovered.


Conclusion
Nosebleeds during freediving can be attributed to various factors, primarily related to pressure changes and environmental conditions. While some cases may resolve with simple home care, persistent symptoms warrant a professional evaluation to ensure there are no serious underlying issues. Always prioritize safety and health, and consider adjusting your diving practices to minimize the risk of further complications.
