CPAP treats your apnea. But weight, exercise, alcohol, and medication all determine how severe your apnea is — and how well you feel. tr8ck is not a CPAP tracker, but it tracks everything that influences your apnea severity. Used together with your CPAP app, it completes the picture.
For CPAP machine data — AHI events per night, mask leak percentage, usage hours — use your device's companion app (myAir, DreamMapper) or OSCAR. tr8ck tracks the lifestyle factors that influence how severe your apnea is: weight, exercise, alcohol, sleep quality perception, and GLP-1 medication if applicable. Together, these give you the most complete picture.
10% weight reduction reduces AHI by approximately 30%. Excess fat around the neck and upper airway increases collapsibility during sleep. Weekly weight trend tracking in tr8ck shows your progress toward the level of weight loss likely to meaningfully reduce your apnea severity.
Regular aerobic exercise reduces AHI by 30–40% even without significant weight loss — likely through improvements in upper airway muscle tone and reduced fluid accumulation in the neck. 4+ sessions per week of moderate aerobic exercise is the threshold associated with meaningful benefit.
Even 2 drinks within 3 hours of bed can increase AHI by 25% or more by relaxing upper airway muscles. This is one of the most modifiable short-term factors. Logging alcohol consumption alongside sleep quality gives you objective evidence of the effect in your own data.
Wegovy (semaglutide) received FDA approval for obstructive sleep apnea in 2024, with trials showing 50% AHI reduction. If you're on a GLP-1 for weight loss or OSA, tr8ck's medication module tracks dose and timing alongside weight trends and sleep quality. See our GLP-1 tracker.
Roughly 50% of people with OSA have positional apnea — significantly worse AHI when sleeping supine (on their back) versus lateral (on their side). If your CPAP data shows much better numbers on nights you sleep on your side, position matters and is worth tracking as part of your sleep notes.
AHI is a technical measure. How you feel during the day — alertness, energy, mood — is what you're actually trying to improve. Tracking daytime alertness and mood in tr8ck gives you the subjective outcome measure that correlates with your quality of life, not just your machine's numbers.
These five data points, tracked consistently alongside your CPAP app data, give you the most complete view of what's driving your sleep apnea severity and daytime function.
Log weight every morning in tr8ck. The AI smooths daily fluctuations to show your real trend line. For sleep apnea, you're looking for a sustained downward trend — you need roughly 10% weight loss to expect meaningful AHI improvement, though any loss helps. Cross-reference your weight trend with any CPAP-reported improvements in AHI over the same period. See also weight loss without counting.
Log every session in tr8ck. Research showing independent AHI reduction through exercise used 4 sessions per week of 30+ minutes of aerobic activity. Resistance training helps with weight loss but the airway-muscle benefits appear to be aerobic-specific. Tracking lets tr8ck correlates exercise weeks with your subjective sleep quality and daytime alertness scores.
Rate your sleep quality each morning and your daytime alertness/energy in tr8ck's sleep module. Even with CPAP treating your apnea events, other factors (alcohol, positional issues, REM behaviour) can affect sleep quality. This daily rating gives you the subjective outcome measure that matters for quality of life. See our full sleep tracking guide.
Log nutrition quality daily, noting alcohol consumption in your evening meal entry. tr8ck's AI can correlate nights where you had alcohol with next-morning sleep quality scores and daytime alertness — giving you objective personal evidence of the alcohol-apnea connection. High-quality nutrition also supports the weight loss that most powerfully reduces OSA severity.
If you're on Wegovy, Ozempic, or Mounjaro, log every dose in tr8ck's medication module. Correlating your dose escalation timeline with your weight trend and sleep quality changes gives you a clear view of how your medication is working — especially useful to discuss with your prescribing physician at follow-up appointments.
After a few weeks of tracking, tr8ck's AI surfaces patterns between your lifestyle choices and your subjective sleep quality and daytime function.
tr8ck can quantify the alcohol-sleep relationship specifically in your data — making the abstract "alcohol worsens apnea" fact a personal, concrete pattern. Many people find this data more motivating than general health advice.
By correlating your weight trend with morning alertness and mood data, tr8ck can show you at what weight loss threshold your subjective sleep quality starts improving — validating that your lifestyle changes are working before your next sleep study confirms it objectively.
The independent airway-muscle benefit of regular aerobic exercise can show up in subjective alertness data before weight changes become significant. tr8ck can detect this exercise frequency-alertness correlation, giving you early encouragement to maintain your exercise routine.
For sleep apnea, the key modules are sleep, exercise, nutrition (including alcohol), weight, and medication. Every module feeds the AI insight engine.
Quitting smoking is a goal you can track in tr8ck, not a separate module.
