If sleep were a therapy, it would be the most effective one in the practice. It is also the first thing most people sacrifice.
What happens overnight
Tissue repair, memory consolidation, hormonal regulation, and immune activity all concentrate in sleep. Short sleep measurably affects glucose handling and appetite signaling within days.
Building a reliable night
Consistent timing. A cool, dark room. Light exposure in the morning and reduced light in the evening. Caffeine timed earlier than feels necessary. Alcohol treated as the sleep disruptor it is.
When to seek evaluation
Loud snoring, witnessed pauses in breathing, or daytime sleepiness despite adequate hours warrant clinical evaluation rather than another habit change.
Key Takeaways
- Sleep drives repair, hormones, and appetite regulation.
- Timing consistency rivals total duration in importance.
- Certain symptoms warrant clinical evaluation.
