Episode notes
The Wired But Tired Phenomenon
- Stress and anxiety disrupt sleep by activating the fight-or-flight response and increasing cortisol.
- Address underlying stress to improve sleep quality rather than just focusing on sleep itself.
Managing Stress for Sleep
- Process stress by writing down anxieties a few hours before bed, not right before.
- If you wake up stressed, try meditation, breathwork, a body scan, or a detailed mental walk.
The Power of Regularity
- Sleep regularity is a stronger predictor of mortality than sleep quantity, even surpassing factors like cancer and cardiovascular disease.
- Maintain a consistent sleep schedule for better health outcomes.
