Sleep Cycles Unveiled: Striking Your Perfect Balance

Date Published

Finding your sleep sweet spot is key to thriving. Aim for 7-9 hours to hit 4-6 full cycles—each with light, deep, and REM stages—for optimal health and brain power. Short sleep (<7 hrs) can impair memory and raise mortality risk, while long sleep (>9 hrs) may fog your mind and heart.

A 20-30 min nap can boost mood and focus without grogginess. Biphasic sleep (night sleep + short nap) might work for some, but polyphasic schedules lack solid evidence.

Prioritize quality cycles over quantity for peak wellbeing.
