🛏️ How Sleep Cycles Work (and Why They Matter)

Sleep is divided into 90-minute cycles, moving through light sleep, deep sleep, and REM (dream) sleep. Waking up in the middle of a cycle can leave you feeling groggy, while waking up at the end of a cycle helps you feel energised and alert.

For optimal rest, aim for 5-6 sleep cycles per night (7.5 to 9 hours total).
