Understanding Sleep Cycles

• Sleep cycles last about 90 minutes on average
• 5 cycles (7.5 hours) is the optimal amount for most adults
• Waking up at the end of a cycle leaves you feeling more refreshed
• 4-6 cycles (6-9 hours) is the healthy range for adults
• Consistency in sleep schedule is as important as duration
