The Sleep Doctor Visits Hypothesis

As part of its quarterly guest speaker series, Hypothesis was treated to a lecture by the Sleep Doctor, Dr. Michael J. Breus, Ph.D. Dr. Breus is a Clinical Psychologist and frequent guest on the Dr. Oz Show. He is a widely recognized leader in field of sleep and has given hundreds of presentations at fortune 500 companies. He's been interviewed on CNN, Oprah, The View, The Doctors, The Today Show, and more.

At Hypothesis, Dr. Breus led a robust discussion on the biology of sleep and how people can leverage their biology to improve their lives. Several highlights include:

  1. Know your chronotype. Your chronotype is your unique biological rhythm. It's how hormones like Cortisol, Adrenaline, and Melatonin, as well as core body temperature and heart rate fluctuate throughout the day. There are 4 chronotypes: Wolves, Dolphins, Bears, and Lions. Interestingly, Hypothesis had an overrepresentation of Wolves and Dolphins, two chronotypes known for creativity and intelligence.

  2. Delay your morning coffee. Wait at least 90 minutes before having your morning coffee. You can optimize the effect of coffee by knowing your chronotype. Bears, for example, should have their coffee between 9:30-11:30am, and between 1:30-3:30pm.

  3. Drink water when you first wake up. Part of the reason you feel groggy in the morning is all the water you sweat out during your sleep. Drinking a glass of water will help you feel refreshed.

  4. There's a best time for everything. Knowing your biological rhythms can help you optimize everything from the best times for exercising, making decisions, brainstorming, going to bed, and yes, even sex.
