Petra Halloran — reads the circadian research at naphelp — nap timing and sleep architecture, written from experience and kept honest.
Reads the circadian research
Petra has spent a decade reviewing circadian research for shift workers and athletes — reading the studies end to end, not the press releases.
Writes About
- Nap timing and sleep architecture
- Chronobiology, plainly told
- What the studies actually measured
She writes the timing guides and enforces the site's one rule: every claim carries its study, and where the evidence is thin, the page says thin.
“Sleep advice fails people when it's confident about things the research isn't. We cite precisely so you can check us.”
