Field notes
The grading key distinguishes strong, consistent support from claims described as plausible but short on good trials, and from popular claims the site says lack support. The insomnia book outlines stimulus control and sleep restriction, including instructions for keeping a sleep diary and adjusting a sleep window. A separate free focus page lists twelve claims for review; the site says readers can report source mismatches by email.
