Dr. Michael Breus explains how your chronotype, your natural sleep-wake preference, shapes health and performance. He describes a lifespan model where infants are "lions" (early risers), children are "bears" (mid-range), and adolescents become "wolves" (late sleepers), a pattern that typically holds for 30 to 40 years before shifting back earlier in your 50s.

So what's so cool about knowing your chronotype is it's like a hack to your entire life.
How many people are trying to be a certain way because media and the wellness culture is saying that you need to be a certain way to be healthy or for optimized health or for aging?
Well, it's interesting because we all go through all of these categories as we age. So lions are babies, because babies go to bed early and they wake up early. Right. And then middle schoolers are kind of in the middle, and bears. Then adolescents become wolves, and. And then your chronotype seems to set for about 30, 40 years. And then when you hit your 50s. Right. And melatonin production starts to slow down, you go backwards.
