Frequently Asked Questions

How accurate are sleep trackers?

Most are 70-90% accurate for sleep duration. Accuracy varies for sleep stages. They're useful for trends, not individual night precision.

Do I really need sleep tracking?

If you struggle with sleep quality, tracking helps identify patterns. For most people, it's helpful but not essential. Use if interested.

What's the best metric to focus on?

Total sleep duration is primary. REM sleep matters for cognitive function. Deep sleep for physical recovery. Focus on overall consistency.

Can sleep trackers improve my sleep?

Awareness itself improves sleep habits. Seeing patterns helps optimize bedtime routines. They're tools, not solutions, for sleep problems.

Which is better: wearable vs. under-mattress?

Wearables are portable and track heart metrics. Under-mattress sensors are non-invasive but less portable. Choose based on lifestyle preference.
