About Mornolin.org

Last updated: May 2026

What this site is

Mornolin.org is an independent reference site focused on the science of morning routines, sleep hygiene, and circadian biology. The site draws on publicly available peer-reviewed research, reports from established health agencies, and observational data from sleep science literature.

Content is oriented toward general readers who want accurate, non-sensationalized information on these topics. No products are reviewed, no supplements are endorsed, and no commercial relationships influence the editorial content.

Geographic focus

While the underlying biology of sleep and circadian rhythms is universal, much of the reference material here addresses specifically Canadian conditions: the country's latitude, seasonal light extremes, climate patterns, and relevant guidance from Health Canada and other Canadian public health bodies.

Canada spans an unusually wide range of latitudes — from Windsor, Ontario at roughly 42°N to Ellesmere Island above 80°N. The practical consequences of this range for sleep timing and seasonal mood variation are documented in the articles on this site.

Editorial approach

Articles on this site aim to reflect the state of published research rather than to promote a particular behavioral program. Where evidence is strong and consistent, that is noted. Where evidence is preliminary, observational, or mixed, that is also noted. Neutral language is used throughout; claims are attributed to specific research where possible.
