About

NapHelp covers the science of short sleep: optimal nap windows, duration thresholds, caffeine timing, and the chronobiology behind why a 45-minute nap leaves you worse off than a 20-minute one. Every piece draws on peer-reviewed sleep research, not wellness influencer advice.

No supplements, no gadgets, no affiliate links. If a study is weak, we say so. The goal is a precise, practical answer to one question most people never think carefully about: how do you rest without breaking your night?
