Sleep researcher Greg Potter, PhD, is back on the podcast today with practical help for those suffering from insomnia. Greg’s research at the University of Leeds on sleep, diet, and metabolic health captured the attention of both scientific and mainstream news outlets on several continents. He is currently an international public speaker, science writer, and consultant, focusing in particular on circadian rhythms, exercise, nutrition, sleep and stress. 

In this podcast, Greg talks about different types of insomnia, and how chronic sleep difficulties create barriers to personal safety and health for 10-15% of adults at any given time. He discusses the best things to do when you’re lying in bed, unpleasantly awake. He also talks about routines and tools for preventing sleep disruption in the first place.
