Top 5 Studies on Nasal Strips and Oxygen Levels
Share
Nasal strips are a simple, drug-free way to improve airflow by opening up nasal passages. They can help with breathing issues like congestion, snoring, and disrupted sleep. Some athletes also use them to ease breathing during workouts. But how effective are they really? Hereโs what research says:
- Breathing Resistance: Studies show nasal strips reduce nasal resistance by 10โ17%, improving airflow during rest and mild activity.
- Exercise Performance: While they ease nasal breathing, they donโt improve oxygen uptake or performance during intense exercise.
- Sleep Quality: They help reduce snoring and improve sleep by supporting steady airflow, especially for those with congestion.
- Athletic Recovery: Useful in recovery phases or low-intensity activities where nasal breathing is more common.
- User Comfort: Safe, non-invasive, and easy to use, they provide temporary relief from nasal discomfort.
Nasal strips work best for improving breathing comfort during rest or light activity, but they donโt enhance high-intensity performance. For Australians, theyโre particularly helpful during allergy seasons or for better sleep. At $36.00 for a pack of 30, BWLL Nasal Strips offer a practical solution for everyday breathing support.
Do Nasal Strips Work
Study 1: Reduced Nasal Breathing Resistance
Researchers Lily S. Wong and Arthur T. Johnson from the University of Marylandโs Biological Resources Engineering department conducted a detailed study on how nasal strips affect breathing resistance. Their research involved 47 healthy participants (14 men and 33 women) aged between 17 and 51 years, providing valuable insights into how these strips improve airflow.
The study tested nasal dilator strips and used precise instruments to measure their impact on nasal resistance. This approach allowed the researchers to clearly quantify the benefits of using nasal strips.
Key Findings
The results showed a reduction of 0.5 cm HโO/Lps from a baseline of 5.5 cm HโO/Lps - equivalent to an overall decrease of about 10%, and 17% when focusing specifically on nasal resistance. Notably, the strips improved airflow consistently during both inhalation and exhalation.
As Wong and Johnson explained:
"Nasal strips reduce nasal resistance by about 0.5 cm HโO/Lps. Thus, nasal strips do have a measurable effect on nasal resistance."
They also noted:
"This study confirmed the results of other studies that showed a reduction of about 10% in nasal breathing resistance, as well as supported the claim of the manufacturer that the nasal strips provide nasal relief."
Practical Applications
These findings highlight the everyday benefits of nasal strips, especially in Australia. A reduction in nasal resistance by 10โ17% can make breathing significantly easier, which is particularly useful for managing congestion caused by allergies, colds, or a stuffy environment.
Since the study focused on healthy adults, the results suggest that nasal strips arenโt just for those with respiratory issues. They can also benefit anyone looking to improve airflow - whether for better sleep, enhanced athletic performance, or simply easier breathing during daily activities.
The consistent improvement during both inhalation and exhalation is especially helpful for sleep. By keeping airways open throughout the night, nasal strips can enhance sleep quality and provide relief that goes beyond a placebo effect.
Study 2: Exercise Performance Review
A systematic review examined how nasal strips affect oxygen uptake, heart rate, and perceived exertion during exercise. The goal was to determine whether these strips provide any measurable benefits for athletes and fitness enthusiasts during physical activity.
The review focused on peer-reviewed studies involving healthy individuals performing various types of exercise. Researchers measured key performance indicators, including VOโ max (maximum oxygen uptake), heart rate, and subjective exertion ratings, to assess whether nasal strips could enhance physical performance. This approach provided a clear framework for evaluating how the mechanical effects of nasal strips might - or might not - translate into improved exercise outcomes.
Study Outcomes
The findings were clear: nasal strips did not enhance oxygen uptake or overall exercise performance in healthy individuals. Although the strips reduce breathing resistance, this mechanical advantage didn't result in measurable improvements during physical activity.
One key reason is that during intense exercise, people naturally switch to mouth breathing, which bypasses the nasal passages. This physiological response limits the impact of improved nasal airflow on oxygen delivery and overall performance.
Heart rate data showed no significant differences between participants using nasal strips and those who didnโt. Similarly, ratings of perceived exertion - how hard participants felt they were working - did not show consistent improvement. While nasal strips may ease airflow through the nose, this didnโt translate into participants feeling less strain during exercise.
The review highlighted the contrast between breathing demands at rest and during physical activity. Nasal strips can improve nasal airflow when at rest, but the bodyโs reliance on mouth breathing during exercise diminishes their effectiveness for athletic performance.
Relevance for Athletes
For athletes, these findings offer a practical perspective. While nasal strips may improve breathing at rest (as shown in Study 1), their benefits during exercise are limited for healthy individuals with normal respiratory function. This suggests that nasal strips are unlikely to boost endurance, strength, or overall performance in most athletic scenarios.
However, they could still serve a purpose in specific situations. For athletes dealing with nasal congestion from allergies, which is common in Australia during spring and summer, nasal strips may help improve breathing comfort. They could be particularly useful during warm-ups or low-intensity activities where nasal breathing is more prominent.
The review also pointed out that individuals with structural nasal issues or those recovering from nasal injuries might experience different results. For these athletes, the enhanced nasal airflow provided by the strips could be more beneficial, especially in activities requiring sustained nasal breathing or in environments with dust or pollution.
Australian endurance athletes - such as marathon runners, cyclists, or triathletes - should understand that while nasal strips wonโt directly improve VOโ max or race times, they might offer comfort during pre-competition warm-ups or aid breathing during recovery phases. Even if the performance gains are negligible, the psychological benefit of easier breathing could contribute to better preparation and confidence.
For recreational fitness enthusiasts, the takeaway is clear: nasal strips are best suited for comfort rather than performance enhancement. Products like BWLL Nasal Strips can still be valuable for improving breathing ease during low-intensity workouts, yoga, or recovery periods where nasal breathing is more common.
Study 3: Nasal Cavity Volume and Airflow
A deeper look into the impact of nasal strips on nasal anatomy has revealed noticeable changes in the structure of the nasal cavity during use. Researchers used advanced imaging methods like acoustic rhinometry and rhinomanometry to measure these changes in detail.
The study focused on key metrics such as the cross-sectional area of the nasal cavity and inspiratory airflow rates, both before and after applying nasal strips. These tools also assessed the expansion of the nasal valve, the narrowest part of the airway. The results were clear - nasal strips effectively widened the nasal passages, making breathing easier almost instantly.
This immediate widening of the nasal passages provides a mechanical adjustment that directly impacts breathing, delivering temporary but noticeable relief. This effect also plays a significant role in improving sleep quality.
Benefits for Sleep Quality
The enhanced airflow brought about by wider nasal passages has clear advantages for sleep. By supporting consistent nasal breathing, these strips can make a real difference in sleep patterns.
One of the standout benefits is the reduction in snoring. By decreasing resistance and turbulence in the airflow, nasal strips encourage quieter and more stable breathing throughout the night. This can be especially helpful for those dealing with seasonal allergies, a common issue in Australia. By improving airflow, nasal strips can ease congestion caused by allergens, leading to more restful sleep.
Pregnant women, who often experience nasal congestion due to hormonal changes, may also find these strips beneficial. Since theyโre drug-free, they provide a safe option for expectant mothers. Better airflow during sleep can significantly improve comfort and rest, which is vital during pregnancy.
Products like BWLL Nasal Strips are specifically designed for overnight use, with a strong yet comfortable adhesive that stays effective through the night. This consistency helps create a more restful sleep environment, aligning with earlier studies that link improved airflow to better restorative sleep.
Temporary Relief
Itโs important to note that while nasal strips offer immediate benefits, these effects are temporary. Once the strip is removed, the nasal cavity returns to its original state. This makes them a great option for short-term relief from nasal congestion but not a solution for underlying structural issues like a deviated septum or chronic sinusitis.
Regular use of nasal strips can improve sleep quality without altering the nasal anatomy, making them a safe and reliable choice for nightly use.
Study 4: Athletic Performance During Intense Exercise
While earlier research suggested nasal strips might have some benefits in specific scenarios, their effectiveness during high-intensity athletic performance paints a different picture. A detailed systematic review and meta-analysis revealed that external nasal dilator strips did not lead to statistically significant improvements in key performance metrics like maximal oxygen uptake (VO2 max), heart rate, or perceived exertion levels during exercise in healthy individuals.
A standout study from the University at Buffalo tested nasal strips under intense exercise conditions to see if they could delay the switch from nasal to mouth breathing as exercise intensity increased. The findings were conclusive: nasal strips had no measurable impact on nasal-airway resistance, nasal ventilation, or the critical transition point to mouth breathing during high-intensity efforts. Even when the nasal passages were mechanically widened, the strips did not enhance VO2 max or oxygen uptake, as athletes naturally shifted to mouth breathing to meet oxygen demands. These results highlight the limits of nasal strips during peak physical exertion.
Study Limitations
The apparent lack of benefits during intense exercise doesnโt mean nasal strips are useless - it simply underscores their limitations in certain contexts. Athletes with already optimal nasal airflow are unlikely to notice any additional advantages from using nasal strips during high-performance activities.
Frank Cerny, Ph.D., Chair of the University at Buffalo's Department of Physical Therapy, Exercise and Nutrition Sciences, summed up the findings:
"Many athletes use nasal strips, and most aren't wearing them where recommended. We wanted to see if the strips, when worn correctly, have any effect at this level of performance. The answer is, they don't."
Experts in sports medicine note that during intense exercise, cardiovascular capacity becomes the primary limiting factor, not nasal airflow. Essentially, the heart's ability to deliver oxygen-rich blood to the muscles is the bottleneck, rather than how much air can pass through the nasal passages.
Exercise physiologists also highlight that during high-intensity activities like running or cycling, athletes naturally switch to mouth breathing to maximise oxygen intake. This makes nasal strips less relevant for peak performance, though they may still be useful for individuals with specific anatomical issues or during less demanding phases of activity.
Sports Use Applications
Despite their limited role in intense exercise, nasal strips can still serve a purpose in certain training and recovery scenarios. The key lies in knowing when and where they can be most effective.
For athletes experiencing mild breathing discomfort during warm-ups or low to moderate-intensity training, nasal strips can help maintain easier nasal breathing. Products like BWLL Nasal Strips are particularly suited for these stages, offering a more comfortable breathing experience before transitioning to higher-intensity efforts.
Recovery periods are another area where nasal strips shine. After intense workouts, as breathing slows and becomes more relaxed, nasal strips can aid in reducing post-exercise nasal congestion, allowing for smoother nasal airflow during cool-downs.
Recreational athletes and "weekend warriors" engaging in moderate activities like hiking, casual cycling, or light jogging may find nasal strips more beneficial than elite athletes. Since these activities don't push the body to its cardiovascular limits, improved nasal airflow can enhance breathing comfort and overall enjoyment.
Additionally, athletes with seasonal allergies or mild structural nasal issues may find nasal strips helpful during training. While they might not boost peak performance, they can make daily workouts more manageable by alleviating nasal congestion, supporting consistent training routines.
