Sleep Tracker FAQs

Are sleep trackers accurate?

Most modern trackers are reasonably accurate for sleep/wake detection. Sleep stage detection varies by device technology. Wearables are less accurate than clinical EEG but excellent for tracking trends.

Do I need a sleep tracker?

Not required, but useful for understanding your sleep patterns. Most valuable if you have sleep issues or want to optimize sleep quality.

Can trackers improve sleep?

Trackers themselves don't improve sleep. But awareness from tracking data can motivate better sleep habits. Some devices (like Dreem) have sleep-enhancement features.

Which is better: wearable or pad trackers?

Wearables provide more detailed metrics and all-day tracking. Pads are more comfortable but less feature-rich. Choose based on your priorities.

Do trackers work for couples?

Most wearables track individually. Under-mattress pads can differentiate between two people. Apps can sync for both partners.
