Whether you are a morning person or someone that snoozes multiple times before waking, how you sleep is all due to genetics. Dr. Michael Breus is a clinical psychologist and expert in sleep and insomnia. Today, he discusses the four chronotypes –  the types of sleepers. Instead of early bird or night owl, are you a lion, wolf, bear, or dolphin? Each type has an optimal time for doing everything from going to bed and drinking coffee, to having sex and making decisions. 
He also discusses the best and worst sleeping positions, managing insomnia, how temperature affects sleep, and the effects of caffeine, alcohol, and cannabis. As well as sleep apnea, new medical devices, and other products to help you get the best night’s rest.
