Why Your Energy Isn't a Battery — Dr. Oliver Weigelt | EXPRESS

Your energy isn't a phone battery. In this nine-minute edition, Dr. Oliver Weigelt explains why energy reported by employees can rise through the morning before falling later, how the previous night's sleep changes the starting point, and why feeling energized at work doesn't necessarily mean effort has no cost.

Hosted by Neil Hedley. For the full conversation and a closer look at the study, see the full-length episode of The Snooze Button (listen to the complete episode).
