Sleep Quality Matters More Than Quantity, Experts Say
April 30, 2025
New findings suggest that the quality of sleep cycles, particularly deep sleep and REM phases, has a greater impact on cognitive function and physical recovery than total hours spent sleeping.
Sleep researchers emphasize that getting enough deep and REM sleep is more important than simply logging hours in bed. Strategies for better sleep quality include maintaining a consistent bedtime, reducing screen time before bed, and creating a calming nighttime routine. If you struggle with sleep, consider tracking your sleep stages with a wearable device and consulting a sleep specialist.
