You might think a good night’s just rest means getting through the night without any issues, but there are actually four quantifiable factors sleep scientists use to measure sleep quality. This is exactly what “a good night’s sleep” entails.

In the most recent issue of the journal Sleep Health, the US National Sleep Foundation explained exactly what getting a good night’s sleep means when it comes to scientific studies. The four factors, as explained by Cari Romm at Science of Us, are:
- You take half an hour or less to fall asleep.
- You wake up no more than once per night.
- If you do wake up in the middle of the night, you fall back asleep within 20 minutes.
- You’re asleep for at least 85 per cent of the time you spend in bed.
Of course, these factors are only for overnight sleeping sessions and do not necessarily work with napping and other short forms of sleep. So, did you get a good night’s rest last night? Now you can know for certain.
