FAQ
Strapflow FAQ.
About the product
What's actually in the pack?
30 black, dog-bone-shaped nasal strips. Smart-Flex band technology. Hypoallergenic, sweat-resistant adhesive. One pack = one month at one strip per night.
Why black instead of beige or clear?
Because beige nasal strips look like a medical device. Black strips look like part of an athlete's kit. Same function, different signal. Wear them on the court, on the bike, on the trail, and to bed without looking sick.
How is this different from the strips at the drugstore?
Drugstore strips are designed primarily for nighttime snoring relief. Strapflow is engineered for athletic performance — stronger Flex band, sweat-resistant adhesive, 12-hour hold, and a low-profile black aesthetic built for under helmets and headbands.
Are these the same as Hostage Tape?
No. Hostage Tape is mouth tape — it forces nasal breathing by sealing your mouth shut. Strapflow is the complement: it opens your nasal airway so nasal breathing is physically easier and more sustainable. Many athletes wear both.
How to use
How do I apply a strip?
Clean and dry the bridge of your nose. Peel the strip. Press across the bridge with the dog-bone ends sitting over each nostril. Press for 15 seconds — the adhesive activates with skin warmth.
How long does one strip last?
Up to 12 hours. Designed for overnight wear or a full training session.
Can I wear one during exercise?
Yes — that's actually what they were built for. Sweat-resistant adhesive. Worn under helmets, headbands, and goggles. Stays put through running, lifting, cycling, racket sports.
What about sleep?
Yes — the highest-leverage use case. Most users see HRV improvements within 7 days of nightly nasal-strip wear, and sleep depth improvements within 1–3 nights.
Can I reuse a strip?
No. The adhesive is single-use. Each strip is designed to peel cleanly off skin without breaking but won't reapply effectively a second time.
The science
Does nasal breathing actually improve performance?
Yes — the science is robust. Your nose produces up to 6× more nitric oxide than your mouth, which dilates blood vessels and improves oxygen delivery. Buteyko Method research has shown nasal breathing during exercise lowers heart rate at the same pace and improves CO₂ tolerance, which directly translates to endurance gains. See the protocol article on our blog for the full reading list and an 8-week training plan.
What's the science you cite?
James Nestor's Breath, Patrick McKeown's The Oxygen Advantage, and Dr. Konstantin Buteyko's original 1950s research. Plus peer-reviewed studies — Lundberg et al. (nitric oxide from the nose, 1996), Dallam et al. (nasal vs. oral breathing in runners, 2018).
What's the "Inhale 4, exhale 8" protocol?
A slow-breathing technique popularized in Breath: inhale through your nose for 4 seconds, exhale slowly through your nose for 8 seconds, repeat for 5 minutes. Activates the vagus nerve, lowers heart rate, raises HRV, and trains CO₂ tolerance over weeks. Works without equipment; works dramatically better when your nasal airway is unobstructed.
Fit, comfort, allergies
Are they comfortable?
Yes. Hypoallergenic, skin-safe adhesive designed for 12-hour wear. Most users report forgetting they have one on within minutes.
What if I have allergies or chronic congestion?
Mild allergies are fine — Strapflow physically holds the airway open, which actually helps. Severe chronic congestion or anatomical issues (deviated septum, polyps): consult an ENT first.
Will it irritate my skin?
The adhesive is medical-grade hypoallergenic and we haven't seen widespread irritation in over a year of athlete testing. If you have particularly sensitive skin, do a 30-minute patch test before overnight wear.
What if I have facial hair?
Strip placement is across the bridge of the nose, above the mustache area. Facial hair on the cheeks and upper lip doesn't interfere.
