If you want to understand why you're still tired after 8 hours of sleep, biohacker Dave Asprey uncovers the hidden flaws in modern rest habits in this episode of Gaia Shorts. Spending a full night in bed does not guarantee your body is actually repairing itself. Drawing on fifteen years of biometric sleep tracking and personal recovery from severe exhaustion, Asprey explains how to shift your focus from mere time in bed to genuine physical restoration.
Many common causes of waking up tired stem from fragmented rest rather than a lack of time. While standard advice focuses strictly on clocking eight hours, unrefreshing sleep causes often trace back to circadian rhythm disruption, poor bedroom environments, and cellular strain. Asprey breaks down how to improve sleep quality by aligning evening routines with your internal clock, supporting mitochondrial energy and chronic fatigue recovery through targeted lifestyle adjustments. When your body drops into the proper sleep architecture and REM cycles, your brain detoxifies and energy reserves replenish.
Restoring your daytime vitality begins with understanding the biology of your nightly rest. Explore these data-driven strategies and begin your journey toward revitalizing, high-efficiency sleep on Gaia.
