Episode notes
Snoozing and Stress Response
- When an alarm interrupts sleep, the body releases cortisol as a stress response.
- Repeated snoozing multiplies this stress and confuses the body's sleep-wake cycle.
Impact of Snoozing on Sleep Cycle
- Snoozing restarts a short sleep cycle without enough time for restorative REM sleep.
- This can lead to drowsiness and confusion, potentially impacting mental health.
Cardiovascular Impact of Snoozing
- Professor Matthew Walker describes being woken by an alarm as a "cardiovascular assault."
- Snoozing repeats this assault due to blood pressure and heart rate spikes.
