How Much REM & Deep Sleep Do You Need? (Sleep Doctor Explains) | Boots UK
Video Overview & Insights
How much REM sleep and deep sleep do you actually need—and what happens if you’re not getting enough?
If you’ve ever woken up feeling tired after a full night’s sleep, your sleep stages could be the reason. In this video, a sleep specialist explains how REM sleep, deep sleep, and sleep cycles impact your energy, brain function, and overall health.
This guide covers:
How much deep sleep you need each night
How much REM sleep is normal
Why you might not be getting enough deep sleep
The key differences between REM vs deep sleep
How to improve sleep quality naturally
Many adults get enough hours of sleep—but not enough restorative sleep. Poor deep sleep and REM sleep can affect memory, mood, focus, and physical recovery.
Whether you're struggling with sleep, feeling constantly tired, or just want to optimise your health, understanding your sleep cycle is essential.
