Episode notes
Micro-Awakenings Are Normal Yet Impactful
- Nighttime micro-awakenings commonly occur 4–6 times per night and often mark the end of sleep cycles.
- They frequently go unnoticed but can reduce total restorative sleep time.
Multiple Causes Raise Awakening Risk
- Several factors increase micro-awakenings, including anxiety, asthma, acid reflux, and arthritis.
- Caffeine, alcohol, tea, tobacco and falling melatonin with age also raise their likelihood.
Sleep Cycles Explain Brief Awakenings
- Human sleep runs in ~90-minute cycles ending with brief 30–40 second awakenings.
- Deep slow-wave sleep dominates early night while light sleep and REM later increase micro-awakening likelihood.
