Sleep Smarter book club questions

1. 1.

   Stevenson describes his own health deterioration as a catalyst for taking sleep seriously. Is there a threshold of suffering that typically precedes genuine lifestyle change, or is it possible to act before crisis?

2. 2.

   The book argues that light exposure is the single biggest controllable factor in sleep quality. How much of your current light environment — phone use, overhead lighting, bedroom conditions — did you design intentionally?

3. 3.

   Caffeine's long half-life means afternoon coffee affects sleep you may not connect to it. How would you run an experiment to test whether caffeine is affecting your own sleep?

4. 4.

   Social jetlag — the mismatch between weekday and weekend sleep timing — accumulates like regular jetlag. What would you have to give up to maintain consistent sleep timing seven days a week?

5. 5.

   Stevenson recommends getting morning sunlight within thirty minutes of waking. How feasible is that for your current life, and what would make it more possible?

   The book connects sleep quality to weight regulation, cognitive function, athletic performance, and mental health. Which of those connections surprised you most?

7. 7.

   Alcohol's effect on sleep is well-documented but rarely discussed in conversations about drinking. Does knowing it suppresses REM sleep change how you think about evening alcohol consumption?

8. 8.

   Many of the book's recommendations are low-cost — dark curtains, earlier caffeine cutoff, cooler bedroom. What has stopped you from already implementing the ones you've known about?

9. 9.

   Sleep anxiety — worrying about not sleeping well — is itself a cause of poor sleep. How would you approach someone whose main sleep problem is the fear of not sleeping?

10. 10.

    The book was written for individual optimization. But sleep is also a social and structural issue — shift workers, caregivers, and people in noisy neighborhoods face constraints individuals can't solve alone. How much of Stevenson's framework applies across different life circumstances?

11. 11.

    If you ran Stevenson's twenty-one-day protocol seriously, which week-one changes would feel easy and which would require real sacrifice?

How to run the discussion

• Pick six to eight, not all of them. An hour of real discussion covers fewer questions than anyone expects, and racing the list is what makes a book club feel like homework.
• Open with what people noticed, not what they concluded. Asking for a verdict first hardens opinions before anyone has heard each other.
• Let the disagreement run. The questions below that split a room are the ones worth the time; the ones everyone answers the same way can be skipped.
• Ask the quiet person a specific question. A direct, narrow question is far easier to answer than an open invitation to contribute.
