A sleep tracker earns its keep as a pattern finder. One night of data tells you almost nothing. A few weeks of sleep tracker data, lined up against what changed in your life, can tell you a lot, and some of it is worth bringing to your doctor.
I compared the Apple Watch, Whoop, Oura Ring 5 and Garmin Cirqa for focus and sleep in a post on the best wearable for ADHD. This one is about what to do with the data, especially when something about your body changes.
Why sleep matters so much with ADHD
Poor sleep and ADHD tend to travel together. Many adults with ADHD fall asleep late and wake up tired, and insomnia estimates for adults with ADHD run anywhere from 43% to 80% (Wynchank et al., 2017, as summarized in a 2024 study on sleep problems in adults with ADHD). Then short or broken sleep makes inattention, irritability and impulsivity worse the next day.
Light is one lever worth tracking. In a small 2006 trial published in the Journal of Clinical Psychiatry, 29 adults with ADHD used bright light in the morning for three weeks. Their body clocks shifted earlier, and that shift was the strongest predictor of improvement in their ADHD symptoms. The trial had no placebo group, so treat it as a lead rather than proof. Still, getting outside in the morning costs nothing, and your tracker can show whether your bedtime starts moving earlier.
Sleep apnea muddies the picture further. Attention, concentration and vigilance are often impaired in people with obstructive sleep apnea, as a Current Psychiatry review pointed out back in 2004, so untreated apnea can look a lot like ADHD. If you snore, wake up gasping or never feel rested, ask your doctor whether a sleep study makes sense, especially before assuming it’s all ADHD. Untreated apnea also adds up over the years: the American Academy of Sleep Medicine links it to high blood pressure, heart disease, stroke, diabetes and depression.
What my own data showed me
A few things surprised me once I had months of data in front of me.
Sleep medication didn’t buy me better sleep. Even sedatives like Ambien and Benadryl didn’t improve my sleep by the numbers. That’s my experience, not advice, but it lines up with the American Academy of Sleep Medicine’s insomnia guideline, which recommends against diphenhydramine (the drug in Benadryl) for sleep. Talk with your doctor before starting or stopping anything.
What did help was boring: going to bed at the same time every night. My energy is noticeably better when I hold that routine, and travel shows me how quickly it falls apart when I can’t.
Alcohol hits me harder than it used to. I can see it in the next morning’s numbers, and I honestly can’t tell whether I was always this sensitive or whether it came with age.
VO2 max has become a kind of windsock for my cardiovascular health. It isn’t precise, but the trend gave me something concrete to talk through with my doctor.
And the one I didn’t expect: after a COVID shot, my body temperature shot up. Seeing it on the graph made the shot’s impact on my body concrete in a way I wouldn’t have noticed otherwise.
Start by tagging your day
Each app gives you a way to record what you did next to how you slept. Whoop has the Journal, Oura has Tags and Garmin Connect has a free feature called Lifestyle Logging. On an Apple Watch, the Health app holds some of this, and an app like Athlytic ties it to your sleep. Tag consistently for two or three weeks before you read anything into it.
A simple two-week experiment
Pick one thing you suspect is hurting your sleep. Then:
- Spend one week living normally and tagging it, so you have a baseline.
- Change that one thing for the next week. Only one, or you won’t know what made the difference.
- Compare the weekly averages, not single nights. One bad night after a late dinner proves nothing; a week of them might.
- Set a daily phone reminder to tag. With ADHD, the tagging is the step that slips.
A word on accuracy. These devices are decent at telling when you’re asleep and for how long, and much rougher on sleep stages. A 2022 study that tested six wearables, including older Apple Watch, Oura, Whoop and Garmin models, against a sleep lab found 86% to 89% agreement on sleep versus wake but only 50% to 65% on sleep stages (Miller et al., 2022). Trust the trend in your total sleep and bedtime more than any one night’s deep sleep number.
Perimenopause and cycle changes
Sleep often gets worse during perimenopause, and mood can shift along with it. A tracker can’t tell you whether you’re in perimenopause. It can put your symptoms, cycle and sleep on one timeline for your doctor. The apps differ quite a bit:
My wife and co-founder, Teri Schroeder, LCSW, put it this way: “For a lot of women, especially if they have had a hysterectomy, it can be hard to track everything going on with your body, especially if they are busy. Throw in perimenopause, and it can turn your world upside down. No matter what you do or don’t do, make changes incrementally and with your doctor. If a smart tracker feels like it could help track body temperature and those changes, and to track your cycle, then do that.”
- Oura: a Perimenopause Check-In built on a standard symptom questionnaire, shown next to your sleep and temperature trends, with a PDF report to bring to your doctor. Custom tags let you log mood, too.
- Whoop: you can mark perimenopause or postmenopause in the Journal and log symptoms like cramps, bloating and brain fog, and it predicts when they may come back. As of October 2026, hot flashes and night sweats weren’t on its symptom list.
- Apple Watch: the Health app’s cycle tracking can flag women 40 and older whose cycles start to vary, and it exports a year of cycle history as a PDF. It works from what you log, not from the watch’s sensors.
- Garmin: Garmin Connect has menstrual cycle tracking. I couldn’t confirm a perimenopause-specific feature.
GLP-1 medications
If you start a GLP-1 like semaglutide or tirzepatide, watch your sleep, readiness and resting heart rate over the following months. Oura added GLP-1 Insights in May 2026, where you log doses and side effects and see them next to your ring data. On Whoop or Garmin, a custom tag does a simpler version of the same thing.
Sleep apnea deserves its own mention here. Tirzepatide (sold as Zepbound) is FDA-approved to treat moderate to severe obstructive sleep apnea in adults with obesity. None of these devices diagnoses apnea, and the Apple Watch is the only one here with FDA-authorized sleep apnea notifications. If you snore loudly, wake up gasping or feel wiped out after a full night, ask your doctor about a sleep study, whatever your scores say.
Any new medication
The same habit works for any new prescription. Say you start something you take at night and notice more wake-ups, more trips to the bathroom or leg cramps. A few weeks of tagged data gives your doctor something concrete. Moving the dose to the morning might be the fix, but that’s their call, not yours.
Bringing sleep tracker data to your doctor
A screenshot of a trend is easier for a doctor to use than “I’ve been sleeping badly.” Before an appointment, pull up the weeks around the change and note the dates you started, stopped or changed something. Oura’s perimenopause report and Apple’s cycle history export are already built for this.
What to bring:
- The dates you started, stopped or changed something
- A screenshot of the trend covering a few weeks before and after
- One sentence on what you changed
- How you actually felt during those weeks, whatever the scores said
What I see in session
Clients sometimes bring tracker data into therapy, and it can help. Seeing your own numbers can make it easier to accept that something like cannabis may be working against your sleep instead of helping it. The research points the same way from another angle: in a systematic review of cannabis withdrawal, trouble sleeping was one of the most commonly reported symptoms, which is part of why sleep can get worse before it gets better when people cut back (Gates, Albertella and Copeland, 2016).
The same data can feed anxiety, too. For some people a low score becomes one more thing to worry about at 6 a.m., and that’s worth noticing early.
My one wish
I’d love for all of these to hand their full data to Apple Health. They do send some. But neither Whoop nor Oura writes heart rate variability to Apple Health, and Whoop sends sleep without the stages. If you’ve moved off the Watch, your Apple Health record has holes in it.
If the numbers start running your nights
If you’re checking scores compulsively, read when tracking turns into worry in my wearables post. And if sleep, focus or worry about your health is wearing you down, that’s worth talking through with one of our counselors.
