Technically, we don't experience sleep in the same way as deep or light sleep. Sleep is cyclical, with stages that progress from light to deep sleep, then back to lighter stages and REM sleep [1].

However, there is a concept called "shallow sleep syndrome" which describes getting enough sleep (in terms of duration) but not achieving the restorative, deeper stages [2]. This can leave you feeling tired and unrefreshed in the morning.

Here are some signs you might be experiencing shallow sleep:

Feeling tired during the day
Difficulty concentrating
Irritability
Mood swings
Difficulty remembering things
If you suspect you have shallow sleep, there are steps you can take to improve your sleep quality. Here are some resources that might be helpful: Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for information about our collection and use of personal data for advertising.
