Do you know your chronotype? Until two weeks ago, I didn't. Turns out, I'm a "lion" chronotype (with a strong tendency to delve into "bear" chrono-typedness). You might be a wolf, in which case you should try working out at 6:00pm and not 6:00am. An early morning run for you might feel like punishment, while an early evening run will provide an enjoyable pick-me-up. Or maybe you're a lion, in which case having a wine, beer or cocktail between 5:30pm and 7:30pm will minimize the chances of sleep disruption from alcohol. Or perhaps you're a dolphin, which means you should schedule any big presentations or work tasks for around 4:00pm, when you're most awake, most alert, and even most confident. You could also be a bear, in which case shifting dinner from 6:00pm to 7:30pm can actually accelerate fat loss and stave off late-night snacking. Interesting, eh? You'll find all the science, the studies, and the facts behind this type of new chronotyping research in the new book "The Power of When: Discover Your Chronotype-and the Best Time to Eat Lunch, Ask for a Raise, Have Sex, Write a Novel, Take Your Meds, and More". A growing body of research actually proves there is a right time to do just about everything, specifically based on your biology and hormones. As Dr. Michael Breus - the author and today's podcast guest - presents in his groundbreaking new book The Power of When, working with your body's inner clock for maximum health, happiness, and productivity can be easy, exciting, fun and pay off big dividends. For example, since reading this book, I've even cut out caffeinated morning coffee and replaced it with decaf, started prioritizing morning and afternoon sex instead of evening sex, and shifted my fiction-based creative writing from 8:00pm to 8:00am.  The Power of When presents a unique program for getting back in sync with your natural rhythm by making minor changes to your daily routine based on your unique "chronotype". In the book, after you've taken Dr. Breus's "Bio-Time Quiz" to figure out your chronotype (e.g. are you a Bear, Lion, Dolphin or Wolf?), you then find out the best time to do over 50 different activities, from when to exercise to have sex to take supplements to ask for a raise to eat breakfast to take a nap and much more. So you can consider this book the ultimate "lifehack".
