Nasal Sprays: A Performance Tool for Athletes
Nasal sprays are emerging as a valuable tool for athletes seeking to optimize breathing and performance. While commonly used for congestion relief, research is now exploring their specific benefits for sports and fitness enthusiasts. From isotonic seawater solutions to targeted decongestants, these sprays offer a unique way to support training goals.
The Science of Breathing and Athletic Performance Nasal patency, or the openness of the nasal passages, is a critical factor for athletes. During intense exercise, the ability to move air efficiently through the nose directly impacts oxygen intake and perceived exertion . When nasal passages are clear, athletes often report easier breathing, which can translate to better focus and endurance during training or competition.
For athletes, nasal breathing plays a key role in warming, filtering, and humidifying incoming air. This is especially important during high-intensity or endurance activities where respiratory rate increases significantly . Maintaining clear nasal passages supports these natural functions, helping the body perform at its best.
Types of Nasal Sprays for Athletes Not all nasal sprays are the same. Athletes typically use two main types to support performance.
Isotonic Seawater Sprays These sprays use a saline solution with a similar salt concentration to the body’s own fluids, derived from natural seawater. They are designed to hydrate and cleanse the nasal passages gently, helping to maintain clear airways without the use of drugs . They are ideal for daily use, especially for athletes training in dry, dusty, or air-conditioned environments.
Oxymetazoline Decongestant Sprays These are over-the-counter sprays containing an active ingredient like oxymetazoline hydrochloride, which works as a vasoconstrictor to reduce swelling in the nasal passages . They provide rapid, temporary relief from nasal congestion. Products like “12 Hour Nasal Decongestant Spray” are common and intended for short-term use as directed .
Clinical Evidence: Seawater Sprays in Training Recent research confirms the benefits of isotonic seawater sprays for athletes. A randomized controlled trial published in 2025 investigated the effects of daily isotonic seawater nasal spray use on high-level athletes during a seven-day training period .
The study, involving 33 athletes who used the spray and a control group of 31 who did not, found significant results. Athletes using the spray reported a notable decrease in subjective nasal resistance, meaning they felt their breathing was easier. This effect increased over time and was statistically significant . This suggests that incorporating an isotonic seawater spray into a training regimen can positively influence how athletes perceive their nasal breathing comfort.
Performance Implications and Proper Use While subjective relief is clear, the impact on objective performance metrics is more nuanced. The study noted that while exercise itself positively affected peak nasal inspiratory flow (PNIF), the isotonic seawater spray did not show a significant additional effect on this objective measure . This means while athletes feel they breathe better, the measurable airflow might be influenced more by exercise alone.
For athletes considering nasal sprays, correct usage is essential for safety and effectiveness.
For decongestant sprays: Follow label directions closely. Adults and children over 6 are typically advised to use 2-3 sprays per nostril, not more often than every 10-12 hours, and not to exceed two doses in 24 hours . To avoid contamination, wipe the nozzle clean after each use .
For seawater sprays: These can be used more frequently, with some products suggesting 3-6 times a day for maintaining clear passages .
A Word of Caution While nasal sprays can be a helpful tool, they are not without risks, especially decongestant types. Overuse of oxymetazoline sprays can lead to “rebound congestion,” where symptoms worsen when the medication wears off .
They may also have side effects like nasal irritation, dryness, or more serious effects such as increased heart rate in sensitive individuals. Individuals with conditions like high blood pressure, heart disease, or glaucoma should consult a doctor before using a decongestant spray .
