MOUTH TAPE
I've Tracked 1,700 Nights of Sleep Data. Here's What Mouth Tape Actually Did.
I want to show you something real.
Not a study. Not a brand claim. My actual sleep data from the last five years. Every number in this article came directly off my Garmin watch, my Whoop band, or my Apple Health app. Over 1,700 tracked nights in total.
My name is Kaivan Dave. I completed the Ironman 70.3. I run, cycle, swim, and lift. And every single night before I go to sleep, I put a strip of mouth tape over my lips.
This is not a wellness trend piece. This is the honest story of why I started, what the data shows, and what I have learned after five years of tracking my sleep across three devices.
Why I Started β Mark Bell, Snoring, and a Problem I Did Not Want to Admit
I first heard about mouth taping around 2019 from Mark Bell. If you do not know him, he is one of the strongest powerlifters in the world and one of the most well-known voices in strength sports. He was talking about mouth taping as a simple way to breathe better at night and recover faster.
At the time, I was drinking heavily. And when I would drink and go to sleep, I would snore. Loudly. I actually have a recording of it. It is not pretty.
I thought mouth tape might help stop the snoring. That was my reason. No deep science. No peer-reviewed studies. Just a guy with a snoring problem who heard something that made sense and decided to try it.
That was the beginning. What happened over the next five years is what this article is about.

I am not a doctor. This is personal data from one person over five years. It is not a clinical trial. What I can tell you is what I measured, what I noticed, and what changed. You take it from there.
The Tracking Setup β 5 Years, 3 Devices, 1,700 Nights
Here is what I have been running:
- Whoop band β worn every night from June 2021 to today. 1,525 tracked nights. Measures sleep performance, recovery score, HRV, resting heart rate, and respiratory rate.
- Garmin watch β 208 tracked nights. Measures sleep stages, sleep score, respiration rate, and awake count.
- Apple Health β historical sync from both devices and my old Apple Watch. Over 2,200 respiratory records and 1,800 HRV readings going back to 2018.
Three independent sensors. Five years of data. All measuring the same body, the same nights, the same habits.
Any single device can be wrong on any given night. But when Garmin, Whoop, and Apple Health all point in the same direction over hundreds of nights, the signal is real. That is the value of tracking across multiple devices over a long time.
What the Data Shows β Before and After Mouth Tape
I started using mouth tape consistently in early 2023. Here is what both devices showed in the three months before versus the nine months after.
First, the Whoop data:
| Metric | Before | After | Change |
|---|---|---|---|
| Sleep performance | 54.0% | 57.2% | β 3.2 pts |
| Respiratory rate | 16.7 rpm | 16.5 rpm | β 0.2 rpm |
| Deep sleep | 1.16 hrs | 1.21 hrs | β 5 min |
| REM sleep | 1.27 hrs | 1.39 hrs | β 7 min |
Now the Garmin data from the same period:
| Metric | Before | After | Change |
|---|---|---|---|
| Awake count per night | 1.8Γ | 1.5Γ | β 17% |
| Deep sleep | 73 min | 77 min | β 5% |
| Respiration rate | 12.8 br/min | 12.3 br/min | β 4% |
| Nights scoring 70+ | 32% | 36% | β 4 pts |
I want to be straight with you. These numbers are not dramatic. Mouth tape did not double my deep sleep. It did not fix everything overnight.
What it did was shift the baseline. A little less time awake. A little more deep sleep. A slightly lower breathing rate. For a normal person that might sound small. For an athlete in training, small consistent gains compound over weeks and months. That is where the real value is.
Two devices showing the same direction is not a coincidence. That is a signal.

My Best Night Ever β July 7, 2023
Four months into consistent mouth tape use, Whoop recorded this:
A 99% recovery score means your body is fully primed. Your nervous system has recovered from the previous day. Your HRV is high and your resting heart rate is low. Everything is ready to go.
I cannot tell you that mouth tape caused that night. I was deep in a training block. Sleep, nutrition, and training load all contributed. But that night happened four months into the most consistent mouth tape period I had ever done. And the data around it was some of the strongest I had ever recorded.
You cannot manufacture a data point like that. It is just what the watch recorded.
The Long Game β 2025 and 2026 Are My Best Sleep Years on Record
Here is what five years of Whoop sleep performance data looks like, year by year:
2023 was my hardest year. Highest training strain, lowest sleep performance. My body was under the most stress it had ever been.
But look at what happened after. 2024 started recovering. 2025 hit the highest sleep performance I had ever recorded. 2026 matched it.
Five years of data. The trend line is clear. Sleep gets better when you stop fighting your own breathing at night.
Deep sleep in 2023 averaged 1.20 hours per night on Whoop. By 2026 it was up to 1.68 hours. That is almost 30 extra minutes of deep sleep every single night. Over a full year, that adds up to more than 180 hours of additional deep restorative sleep.
The Nasal Strip Discovery β What Changed When I Added Both
I did not start with both mouth tape and nasal strips at the same time. I started with one. Got comfortable. Then slowly added the other.
Here is the simple logic. Mouth tape closes your lips so you breathe through your nose. Nasal strips open your nasal passages so your nose can actually handle that airflow. One closes the exit. The other opens the entrance. Together they give your airway the best possible chance to stay open all night.
The nights I use both, I feel it in the morning. If you are already using mouth tape and want to take it one step further, Awesome Nasal Strips are what I reach for.

My Nightly Routine β What I Actually Do
I start winding down around 9 pm. I am usually reading, playing chess, or doing something that does not involve a screen.
I take my sleep gummies as part of the wind-down. Then I get ready for bed.
Right before I sleep, my mouth tape and nasal strips are both on the bedside table. I pick whichever feels right for that night. Some nights both. Some nights just one. I have been doing this long enough that my body tells me what it needs.
That is the whole routine. No complicated protocol. Just consistent tools within reach every single night.
Do not try to do everything at once. Start with mouth tape alone for a week. Pay attention to how your mouth feels in the morning. Dry mouth gone? Good. That is the first sign it is working. Then, once you are comfortable, try adding nasal strips. Build slowly and you will actually stick with it.
What I Would Tell Someone Starting Today
Five years ago I started because I was snoring and someone I respected said mouth tape might help. I was skeptical. I tried it anyway.
Here is what I know now that I did not know then:
- The first night you will notice your mouth is not dry in the morning. That alone is worth it.
- The snoring reduction comes within the first week for most people. Your partner will notice before you do.
- The deep sleep and recovery improvements take longer. Give it a month of consistent use before you judge it.
- Track something. Even just your morning mouth dryness on a scale of 1 to 10. Data makes you a believer faster than feeling alone.
- The combination of mouth tape and nasal strips is more powerful than either one alone. But start with one and earn the upgrade.

FAQs
The first thing I noticed was less dry mouth in the morning. That happened from night one. The sleep score improvements showed up over weeks. The bigger trends in deep sleep and recovery took a few months of consistent use to become clear in the data.
Not always. Both are on my bedside table every night and I pick what feels right. Some nights I use both. Some nights just one. I did not start with both at the same time. I built up slowly. That is what I would recommend for anyone starting out.
In 2021 and 2022, my Whoop sleep performance averaged around 62%. In 2025 and 2026 it is averaging 66 to 67%. That is about a 5 point improvement over five years of consistent tracking and habit building. Mouth tape is one part of that, along with my wind-down routine and sleep gummies.
Snoring from drinking is caused by alcohol over-relaxing your throat muscles. Mouth tape helps by keeping your lips closed so you breathe through your nose, which keeps the airway more structured. That said, I would not use mouth tape on nights of heavy drinking. Alcohol affects your breathing enough that it is safer to skip the tape on those nights.
I use both Whoop and Garmin and they each tell me something different. Whoop is better for recovery and HRV trends. Garmin is better for sleep stage detail. If you are just starting out, any wearable that tracks sleep is better than none. The device matters less than the consistency of tracking.
I use Awesome Mouth Tape for Sleeping. It is the one I helped build specifically for Indian skin, Indian beards, and India's humidity. Medical-grade adhesive, CDSCO approved, βΉ499 for 30 nights. It is the only one I trust on my own face every night.
