Surfer Sinusitis: Causes, Prevention, and Treatment

Repeated exposure to ocean water, bacteria, pollutants, cold air, and wind can irritate the nasal passages and sinuses over time. While “surfer sinusitis” is not an official medical diagnosis, studies show surfers experience increased rates of sinus and upper respiratory symptoms compared to the general population.[1][2]

For many surfers, symptoms become more noticeable after:

• heavy surf sessions

• repeated duck diving

• surfing after rain

• cold-water exposure

• frequent travel or back-to-back surf days

What happens in the sinuses?

Your sinuses normally drain through small openings into the nasal cavity. Repeated irritation from saltwater, bacteria, cold air, and inflammation can disrupt this drainage system.

Over time this may contribute to:

• swelling of the nasal lining

• mucus buildup

• congestion and pressure

• impaired sinus drainage

• recurrent sinus infections

Research in swimmers and aquatic athletes has shown increased rates of:

• chronic rhinitis

• sinus inflammation

• mucosal swelling

• decreased mucociliary clearance (the nose’s ability to clear mucus and debris).[3][4]

Common Symptoms

• nasal congestion after surfing

• sinus pressure or facial pain

• post-nasal drip

• headaches

• reduced sense of smell

• thick mucus

• pressure worsening when bending forward

• recurrent “colds” or sinus infections

Many surfers notice symptoms become worse after:

• rainstorms

• polluted runoff exposure

• cold-water sessions

• long surf trips with repeated exposure

Surfing After Rain Increases Risk

Post-rain runoff significantly increases bacterial and viral contamination in coastal water.

A large prospective study of surfers in California found significantly higher illness rates after wet-weather surfing, including increased upper respiratory and sinus-related symptoms.[1]

Duck diving and wipeouts may force contaminated water into the nasal cavity and sinuses, especially near:

• river mouths

• storm drains

• urban runoff areas

This is one reason many surfers follow the “72-hour rule” after heavy rainfall.

Prevention Strategies

Nasal saline rinses

Many surfers find saline rinses helpful after sessions to clear:

• salt

• sand

• pollutants

• mucus

• bacteria

Sterile saline irrigation may help restore normal mucosal function and improve sinus drainage.[10][11]

Important:

• Use sterile, distilled, or previously boiled water for nasal rinses.

• Never use untreated tap water directly in sinus rinse systems.

Additional prevention tips

• Avoid surfing after heavy rain when possible

• Shower and rinse after sessions

• Stay hydrated

• Manage allergies if present

• Use ear and sinus protection in cold environments

• Limit exposure when already sick or congested
