What we read
- Irregular sleep/wake patterns are associated with poorer academic performance and delayed circadian and sleep/wake timing
Scientific Reports · 2017
Among 61 college students wearing actigraphs for a month, more irregular sleepers had later circadian timing and worse grades — the regularity signal sat beside, not inside, total sleep time.
- Sleep regularity is a stronger predictor of mortality risk than sleep duration: a prospective cohort study
Sleep · 2024
In 60,977 UK Biobank participants with a week of accelerometry, the most regular sleepers had a 20–48% lower mortality risk than the most irregular, and regularity out-predicted duration.
Research from Harvard Medical School · Monash University. We cite their published work. They have no involvement with Anew.
Where this falls down
Still unknown. Almost all of the mortality data is observational — people with chaotic sleep also have chaotic lives — so we cannot promise that tightening a wake window by 30 minutes adds years.
