Tilting your head to the side and letting gravity pull the water out is the fastest fix, and it works most of the time. But water sometimes lodges deeper in the sinuses, where a simple head-tilt does nothing, leaving you with that maddening sloshing sensation hours after you’ve dried off. The anatomy of your nasal passages explains why water gets stuck, and a handful of techniques can coax it out when gravity alone falls short.
Why Water Gets Trapped in the First Place
Your nose is not a simple tube. Behind the nostrils sits a network of bony shelves called turbinates that create winding channels, and above those channels sit your paranasal sinuses: air-filled pockets in the bones of your forehead, cheeks, and between your eyes. Each sinus connects to the nasal cavity through a small opening called an ostium. When you’re underwater, especially if you dive, flip-turn, or get dunked unexpectedly, water can push past those narrow openings and pool inside a sinus cavity.
Once water is inside a sinus, getting it out requires the water to travel back through that same narrow opening, often against gravity depending on which sinus is involved. The maxillary sinuses, the largest pair located in your cheekbones, have their drainage openings near the top of the cavity rather than the bottom. That design is great for keeping mucus from draining constantly while you’re upright, but it means trapped water has to climb upward to escape. That’s why you can still feel water shifting around in your face long after you leave the pool.
Techniques That Actually Clear the Water
Start with the simplest approach and escalate if needed. Most trapped water will come out with one of the first few methods. If water is stuck deeper in the sinuses, you may need a combination.
Gravity and Head Position
Tilt your head so the affected side faces the ground. Pull your earlobe gently outward and downward to straighten the path, and hold the position for 10 to 15 seconds. If you feel the water shift but it doesn’t drain, try tilting your head forward so your chin approaches your chest while keeping the same side angled down. This can help reach water trapped in the maxillary sinus by repositioning the drainage opening lower than the pooled water. Hopping lightly on one foot while your head is tilted adds vibration that sometimes loosens the seal.
Gentle Exhale Through the Nose
Close your mouth, press one nostril shut with a finger, and exhale softly through the open nostril. The goal is a steady, gentle push of air, not a forceful blast. Blowing too hard can drive water further into the sinuses or push it toward the eustachian tubes, which connect your nasal passages to your middle ear. That’s how you end up with a clogged ear on top of a waterlogged nose. Keep the pressure light, roughly the effort you’d use to fog a mirror.
The Valsalva-Style Approach
Pinch your nostrils shut, close your mouth, and try to exhale gently against the closed airway. You should feel a mild pressure build behind your nose and in your ears. Hold for two to three seconds, then release your nostrils and tilt your head to the side. This briefly pressurizes the nasal cavity and can push water out of sinus pockets. Don’t bear down hard; the goal is gentle equalization, not the kind of straining that makes your face turn red. If you feel pain or sharp pressure in your ears, stop immediately.
Steam
Breathing in warm, humid air opens up the nasal passages and can help trapped water find its way out. Run a hot shower, lean over a bowl of steaming water with a towel draped over your head, or simply hold a warm, damp washcloth over your nose and mouth for a few minutes. The warmth helps in two ways: it increases blood flow to the nasal mucosa, which can open the ostia slightly, and the moisture thins any mucus that might be trapping the water in place. Research has shown that steam inhalation can improve nasal patency, the sense of how open your nasal passages feel.1PubMed. Effects of steam inhalation on nasal patency and nasal symptoms in patients with the common cold For a one-time trapped-water situation, a five-to-ten-minute steam session is usually plenty.
Saline Rinse
A saline nasal rinse, whether from a squeeze bottle or a neti pot, flushes the nasal passages with saltwater and can push trapped pool water out along with it. Use distilled or previously boiled water (never straight tap water) mixed with a pre-measured saline packet. Lean over a sink, tilt your head to one side, and pour the solution into the upper nostril. It will flow through the nasal cavity and drain out the lower nostril, carrying trapped water and any irritants with it. If you swim regularly, a post-swim saline rinse is one of the most practical habits you can build.
When It Is More Than Just Annoying
A little water stuck in your nose is uncomfortable but usually harmless. The lining of your sinuses will absorb a small amount of residual water over a few hours, and whatever doesn’t get absorbed eventually drains on its own as you move around. But there are situations where trapped water becomes a real health concern.
Chlorinated Pool Water and Nasal Irritation
Chlorine and its byproducts irritate the nasal lining. Among competitive swimmers, roughly one in five reports nasal or sinus symptoms after swimming.2PubMed Central. Nasal and lung function in competitive swimmers The more contact chlorinated water has with your nasal mucosa, the worse the irritation. Research on swimmers has found that a significant proportion develop a form of non-allergic rhinitis, an inflammatory response driven by the chemical irritation of chlorine rather than an immune reaction to an allergen. The longer chlorinated water sits in your sinuses, the more opportunity those chemicals have to aggravate the tissue.
That neutrophilic rhinitis, as researchers call it, appears to be directly triggered by contact with chlorinated water. Studies have found that using a nose clip, which prevents water from entering the nose in the first place, reduced the inflammatory response in affected swimmers.3British Journal of Sports Medicine. Allergic and non-allergic rhinitis in swimmers: clinical and cytological aspects So if you’re someone who always feels congested or sniffly after the pool, the trapped water itself may be a secondary problem. The primary issue is chemical irritation, and getting the water out quickly (or keeping it out entirely) limits your exposure.
Infection Risk From Contaminated Water
Pool water that enters the sinuses brings whatever is dissolved or suspended in it. In properly chlorinated pools, the bacterial load is usually low enough not to cause trouble. But in lakes, rivers, hot springs, and poorly maintained pools, the story changes. Some researchers have long noted that upper respiratory infections in swimmers are linked to bacteria in the water reaching the nasal passages and paranasal sinuses.4JAMA. PARANASAL SINUS INFECTION AND SWIMMING
The most alarming (though extremely rare) risk involves warm freshwater. Naegleria fowleri, an amoeba found in warm lakes, rivers, and inadequately chlorinated pools, causes a nearly always fatal brain infection called primary amoebic meningoencephalitis.5PubMed. Assessing the risk of primary amoebic meningoencephalitis from swimming in the presence of environmental Naegleria fowleri The amoeba enters through the nose, typically when water is forced up the nasal passages during diving or jumping into warm freshwater. Cases are exceedingly rare in absolute numbers, but the infection is so dangerous that it’s worth knowing the mechanism: water up the nose in warm, stagnant freshwater is the entry route. This is one of the strongest arguments for nose clips or simply holding your nose when jumping into lakes or warm springs.
Preventing Water From Getting In
The easiest way to deal with water in your nose is to keep it from getting there. A few approaches work well depending on how you swim and what bothers you most.
Nose Clips
Competitive swimmers have used nose clips for decades, and they are the single most effective barrier against nasal water entry. Research confirms that nose clips reduce the inflammatory cellular response in swimmers who develop chlorine-related rhinitis, and they also helped swimmers who already had allergic rhinitis feel better after sessions.3British Journal of Sports Medicine. Allergic and non-allergic rhinitis in swimmers: clinical and cytological aspects Nose clips come in several styles: soft silicone pads with a wire bridge, rigid plastic clips, and adhesive strips. The best one is whichever stays on and feels comfortable enough that you forget it’s there. If you’re a recreational swimmer who doesn’t want to bother, even a simple pinch of the nostrils before a dive or flip-turn covers the highest-risk moments.
Breathing Technique
Many casual swimmers inhale through the mouth and don’t think about the nose at all, which leaves the nasal passages open to whatever water sloshes across the face. Experienced swimmers exhale steadily through the nose while their face is in the water. That continuous stream of bubbles creates positive pressure in the nasal cavity that keeps water from entering. It takes some practice, and it won’t help during a cannonball, but for lap swimming it’s the most reliable hands-free prevention method.
Exhale Before Surfacing
A sharp exhale through the nose just before you break the surface clears the nostrils of any water that crept in during the stroke. Freestyle and backstroke swimmers often do this instinctively during their breathing rotation. If you’re swimming breaststroke or doing any stroke where your whole face submerges and surfaces repeatedly, a quick nose-exhale as you come up keeps the sinuses from accumulating water over the course of a session.
The Post-Swim Drip That Happens Hours Later
You’ve dried off, changed, driven home, and then you lean forward to pick something up and suddenly water pours out of your nose. This is one of the more baffling experiences for swimmers, and it has a straightforward explanation. Water that pooled in the sphenoid or frontal sinuses (behind your forehead and deep behind your nose) may not have had a path to drain while you were upright. When you tilt forward, gravity finally aligns with the sinus drainage pathway, and the water comes out in a rush. It can happen hours after swimming because those sinuses are positioned in a way that doesn’t favor drainage when you’re standing or sitting upright.
This delayed drainage is harmless, just startling. If it happens to you regularly, spending an extra minute or two doing a thorough gravity-tilt routine immediately after swimming (head down, rotated side to side, held for several seconds in each position) can clear those deeper pockets before you leave the pool area. Some people find that a brief stint in a forward fold, the kind you’d do in a yoga class, drains the last holdouts.
When the Feeling Won’t Go Away
If you still feel pressure, fullness, or sloshing in your sinuses more than a day after swimming, the sensation may no longer be caused by actual trapped water. A few things can mimic that waterlogged feeling:
- Mucosal swelling: Chlorine irritation or an allergic response can make the nasal lining swell, creating a sensation of fullness or blockage that feels like water but isn’t.
- Sinus infection: If bacteria from the water colonize the irritated sinus lining, you can develop sinusitis. Symptoms include thick or discolored nasal discharge, facial pain or pressure that worsens when you lean forward, and sometimes fever.
- Eustachian tube dysfunction: Water that traveled toward the back of the nose can irritate the openings of the eustachian tubes, causing a muffled-ear sensation and a feeling of pressure that persists well beyond the swim.
Mucosal swelling usually resolves on its own within a day or two, and a saline rinse can speed it along. A sinus infection that follows swimming, especially if you were in a lake or unchlorinated water, warrants a visit to a doctor, particularly if you develop a fever or the discharge turns green or yellow and persists beyond a week. Eustachian tube issues generally resolve with swallowing, yawning, or gentle Valsalva maneuvers, but if ear pressure or muffled hearing lingers for more than a few days, see a healthcare provider.
Swimmers’ Nose and Chronic Congestion
People who swim several times a week often develop a chronic, low-grade nasal congestion that flares after every session. This is different from a single episode of trapped water. The repeated exposure to chlorinated water creates an ongoing cycle of irritation and inflammation. Research suggests this pattern is irritative rather than allergic in nature, essentially a chemical burn that never fully heals between exposures.3British Journal of Sports Medicine. Allergic and non-allergic rhinitis in swimmers: clinical and cytological aspects
If you’re in this category, the strategies above still apply but become a routine rather than an occasional fix. A saline rinse after every swim session washes out residual chlorine. A nose clip during the swim limits exposure. Some swimmers find that applying a thin layer of petroleum jelly or a barrier balm just inside the nostrils before swimming provides an extra layer of protection against chemical irritation, though this hasn’t been well-studied in clinical settings. Switching to an outdoor pool, where chloramine byproducts dissipate more readily than in an enclosed indoor pool, can also reduce the irritant load. And if you have access to a saltwater pool or one that uses UV or ozone sanitation alongside reduced chlorine levels, the difference in nasal comfort can be dramatic.
For serious competitive swimmers who train daily, it’s worth discussing the issue with a sports medicine physician or an ENT specialist. Chronic nasal inflammation can affect sleep quality, exercise tolerance, and overall comfort in ways that are easy to dismiss but genuinely affect training and daily life. Prescription nasal corticosteroid sprays can manage the inflammation, and an ENT can rule out structural factors like a deviated septum or nasal polyps that make certain swimmers more susceptible to water trapping than others.
