Swimming-Related Ear, Nose, and Throat Issues: Prevention and Management of Otitis Externa and Sinusitis

Introduction

For many swimming enthusiasts, the feeling of ear fullness, runny nose, or sinus pain after swimming is a persistent annoyance. ENT issues are the third most common health problem among swimmers (after shoulder and knee injuries), but they are also the easiest to avoid through proper preventive measures. Understanding how the swimming environment affects the ear canal and nasal mucosa, as well as how to care for them correctly, is essential hygiene knowledge for every swimmer.

Swimmer’s Ear (Otitis Externa)

What is Swimmer’s Ear?

The formal medical term for Swimmer’s Ear is Acute Otitis Externa, an infection of the skin and subcutaneous tissue of the external ear canal. A healthy ear canal is protected by a mildly acidic (pH 4–5) sebaceous gland secretion that has antibacterial properties. However, when the ear canal is exposed to pool or seawater for extended periods:

• Water maceration softens the stratum corneum and compromises the protective barrier
• Chlorinated water or seawater alters the ear canal’s pH, weakening the natural antimicrobial defense
• A moist, warm ear canal environment becomes a breeding ground for bacteria (most commonly Pseudomonas aeruginosa and Staphylococcus aureus)

Recognizing Symptoms

Severity	Symptoms	Recommended Action
Mild	Slight itching or fullness in the ear canal	Keep ear canal dry, use preventive measures
Moderate	Noticeable pain (worsens when tugging the auricle), partial blockage, slight discharge	Seek medical attention for antibiotic ear drops
Severe	Intense ear pain radiating to the neck, complete ear canal blockage, swelling extending to the auricle	Seek immediate medical attention; systemic antibiotics may be required

Important distinction: The pain of otitis externa (swimmer’s ear) worsens noticeably when pulling on the auricle or pressing on the tragus (the cartilage in front of the ear opening), which differs from otitis media (where pain is accompanied by a blocked sensation and hearing loss).

Prevention Methods

Before swimming:

• Ensure the ear canal is free of cerumen impaction (excess earwax traps water); have it cleaned regularly by an ENT specialist
• Earplugs can be used, but choose appropriate waterproof styles—plugs that are too tight may actually irritate the ear canal skin

After swimming:

• Tilt your head to the side and hop on one foot several times to allow water to drain naturally
• Gently pat the auricle dry with the corner of a towel; do not insert the towel into the ear canal
• Use a hair dryer on the lowest heat setting, held about 30 cm from the ear, to blow-dry for 30 seconds to aid drying
• “Swimmer’s ear prevention solution”: You can make your own (50% white vinegar + 50% isopropyl alcohol) or purchase a ready-made product from a pharmacy. After swimming, instill 3–5 drops into each ear canal, shake your head, and let the liquid drain out. This effectively restores the acidic environment of the ear canal

Absolutely avoid:

• Using cotton swabs to clean inside the ear canal—cotton swabs damage the protective keratin layer and may push earwax deeper
• Digging in the ear canal with fingers—this introduces bacteria from the skin’s surface
• Continuing to swim when there are wounds or an active infection in the ear canal

Swimming and Sinus Issues

Causes of Sinusitis

Sinusitis in swimmers involves two main mechanisms:

1. Water entering the nasal cavity: During diving, butterfly stroke entries, or backstroke flip turns, water can flow backward into the nasal cavity and then into the sinuses. If the water contains bacteria or fungi, it may trigger infectious sinusitis.
2. Chlorine irritation: Chlorine compounds in swimming pools (especially chloramines) are potent irritants to the nasal mucosa. Prolonged exposure can cause chronic mucosal inflammation, impair ciliary function, and reduce the sinuses’ self-cleaning ability.

Recognizing Symptoms

• Acute sinusitis: Facial pain and pressure (forehead, under the eyes, upper jaw area) appearing 1–3 days after swimming, thick yellow-green nasal discharge, fever
• Chronic sinusitis: Year-round nasal congestion, post-nasal drip, reduced sense of smell, with symptoms lasting more than 12 weeks

Preventive Measures

• Using a nose clip: For butterfly swimmers, backstroke flip turns, and swimmers who are not accustomed to controlling nasal airflow, a nose clip effectively prevents water from entering the nasal cavity and is the most direct preventive tool.
• Practicing underwater exhalation: Continuously exhaling through the nose or mouth maintains positive pressure at the moment of water entry, preventing water from flowing backward into the nasal cavity. This requires practice, but once it becomes a habit, it is a more natural protective method than a nose clip.
• Nasal irrigation after swimming (saline rinse): Using a neti pot with physiological saline (0.9% NaCl) to rinse the nasal cavity flushes away chlorine residue, bacteria, and allergens. This is a preventive measure supported by substantial research and is recommended after every training session for regular swimmers.

Choosing a Suitable Swimming Environment

Environment	Advantages	Disadvantages
Indoor chlorinated pool	Convenient and widely available, stable water quality control	High concentration of chloramine volatiles (accumulate indoors), strongest mucosal irritation
Outdoor chlorinated pool	Better ventilation, volatiles do not accumulate	Sunlight breaks down chlorine, water quality control is relatively less stable
Saltwater pool	Least mucosal irritation, close to physiological saline concentration	Requires special equipment, higher cost
Natural waters (sea, rivers)	Low chlorine irritation	Diverse microorganisms, higher infection risk

When to Seek Medical Attention

The following situations should not be delayed—seek medical attention immediately:

• Severe ear pain that prevents sleep
• Redness or swelling of the auricle or surrounding skin (be alert for malignant otitis externa, which is more common in diabetic patients)
• Sinusitis accompanied by high fever (above 38.5°C)
• Severe headache or vision changes (to rule out intracranial complications)
• Sinus symptoms that have not improved after more than 10 days

Practical Advice

• Swimming enthusiasts are advised to have a preventive ENT examination once a year to confirm the baseline health of the ear canals, nasal cavity, and sinuses.
• If swimmers have a cold or upper respiratory infection, their mucosal defenses are already compromised; swimming during this time makes them more susceptible to secondary sinusitis. It is recommended to pause swimming for at least 3–5 days.
• If ear pain or sinus discomfort occurs after every swim, it may indicate particular sensitivity to pool chlorine. Consider switching to a saltwater pool, or reducing the number of swimming days per week to allow the mucosa adequate recovery time.

Conclusion

Although ENT issues from swimming are troublesome, the vast majority can be prevented and properly managed. By developing correct hygiene habits such as drying the ear canals and rinsing the nasal passages after swimming, and knowing when to seek medical care, swimming can continue to be an activity that brings health and enjoyment—not a source of recurring infections.
