Self-help ✦ Penny’s Take
The Business of Sleep
Vicki Culpin · 2018
78/100
👍 Worth It
Culpin makes a compelling, evidence-backed case that sleep is a professional asset — and she has the academic credentials and access to senior leaders to make it more than self-help boilerplate. Bloomsbury's editorial stamp adds weight, and the workplace-centered framing is sharper and more actionable than general wellness sleep books.
