How people get it: Sold over the counter. Most fitness trackers also track sleep.
The basics
What it is
Trackers typically display sleep and wake time. Some trackers also estimate light versus deep sleep, how often you wake, and how long you stay awake.
How it works
Makers don't share details of the technology, but most appear to rely on motion detection.
What people use it for
People use them to monitor their sleep patterns.
What the research has found so far
The review's authors said the devices can still be useful for tracking general sleep patterns.
On sleep trackers and aging, PubMed lists 9 trials in people, 23 studies that watched people over time, 0 animal and lab studies. See the counts and searches
Stage 2 because 9 published trials and 139 registered trials in people have been found, but no large ones yet.

Questions to ask your doctor
- Would sleep trackers be useful for me, and what should I do with the readings?
- Which type or model would you trust, and how do I use it so the readings are accurate?
- Could I bring it to an appointment to check it against your equipment?
- How often should I share the results with you, and which numbers should make me call?
This is general information gathered from the sources listed, not medical advice. Talk to your doctor before starting anything new.
Devices you can buy
Read from each maker's page. The research stage is for this kind of device, not proof that a particular model is accurate or right for you.

Do Sleep Trackers Actually Work? ↗
“It really depends what you're looking to get from them. Most sleep trackers use a very basic technology called an accelerometer, which basically means they just look at your movement.”
A Cleveland Clinic sleep specialist says sleep trackers estimate total sleep reasonably well but are less reliable for detailed sleep stage data.
Bad bedfellows ↗
“Sleep trackers have pros and cons, but the devices may also lead to slumber-sabotaging anxiety.”
Harvard experts say sleep trackers have pros and cons, and their data can cause anxiety that disrupts sleep.

Trials
None of the registered trials of Sleep trackers is one we have linked as aging-related yet.
ClinicalTrials.gov lists 139 registered trials that mention Sleep trackers, for any condition (the count in The science below). Here we show the ones about aging. See them all ↗
