Questions & Answers

Q: Should I rely on sleep scores provided by sleep trackers?

Sleep scores provided by sleep trackers are not reliable measurements of sleep quality, as they are calibrated against outdated definitions of sleep stages and based on subjective grading.

Q: How can I assess my sleep quality without relying on sleep scores?

You can assess your sleep quality by paying attention to indicators such as heart rate variability, respiratory rate, how you feel upon waking up, and whether you had a hard time sleeping or woke up frequently during the night.

Q: Do sleep stages need to be the same every night?

No, sleep stages can vary depending on your activities and goals. It doesn't make sense to expect the same sleep stages every night, just as you wouldn't expect your muscles or nutrition to be the same every day.

Q: Can the perception of sleep affect performance?

Yes, the perception of sleep can affect performance. Studies have shown that if you believe you had poor sleep, even if you actually slept well, your performance can still be affected. This phenomenon is known as orthosomnia, where sleep tracker scores can induce insomnia.
