Understanding Your Sleep Cycles

Published on 12 April 2026 | By Editorial Team

Waking up tired even after 8 hours of sleep? The answer usually lies in sleep cycles, not just the duration. A typical sleep cycle lasts about 90 minutes, and understanding this can help you organise your rest more effectively.

The Importance of REM and Deep Sleep

During the night, we cycle through light sleep, deep sleep, and REM (Rapid Eye Movement). Deep sleep is when we maximise physical restoration, while REM is crucial for memory consolidation and cognitive health behaviours.

Organise Your Wake-Up Time

Waking up in the middle of a deep sleep phase leaves you feeling groggy. Try to organise your sleep schedule so you wake up at the end of a cycle. This simple change can help maximise your morning alertness and productivity.
