New research suggests that waking up in the middle of the night might be a normal human sleep pattern, not a sign of insomnia. This ancient biphasic sleep cycle, common before artificial light, involved a period of wakefulness after initial sleep.
Key takeaways
- Middle-of-the-night awakenings may be a natural sleep pattern
- Artificial light disrupted historical biphasic sleep cycles
- This could inform AI-assisted productivity strategies
- Rethink sleep disruptions as potential work windows
Why it matters
Understanding natural sleep cycles could help AI users optimize their productivity and well-being. Instead of fighting natural wakefulness, individuals might leverage these periods for focused tasks or creative thinking, improving work efficiency.
