Sleeping Like a Polar Bear

We’ve decided to do a series of episodes on the fundamentals of good health - each containing the best practical information we’ve come across for improving the quality of your life and achieving your goals. We’re focusing on the most commonly asked-about areas, such as stress and hormesis, movement and exercise, and diet and nutrition. Today we’re kicking it off with a discussion about one of the most important, often the most frustrating, and easily the most overlooked pillar of health: sleep.

On this podcast, Megan Hall and Clay Higgins draw from their years of combined health coaching experience to bring you their best advice for getting great sleep. They explain why you should care about the quality of your nighttime routine, and they discuss the impact of light, food and exercise on your ability to sleep well. They also share their opinions on supplements and technology designed to enhance sleep and talk about some of the more common behaviours that can lead to insomnia.

Be sure to follow along with Megan’s outline to get the most out of this episode.
