054 Chronotypes and Optimal Productivity

Every day, we wake up, we go about our day, and then we go to bed. In that span of one Earth rotation, we hope to and frequently achieve our basic needs. And, many of us want to do more. This where an understanding of chronotypes and how it impacts your productivity can help! Most people know about night owls, and maybe about morning larks (or, “early birds”) and hummingbirds. But, in this cast, we discuss two books that talk about chronotypes and optimal daily productivity in some unique ways.

How to determine your chronotype via core body temperature:

“You want to have a fairly accurate temperature reading. A lot of the ear digital thermometers are ones that are quite helpful. What you’ll start to see, again you’ll start to see these differences in core body temperature rising and falling. With my lions, their core body temperature has a tendency to rise one to two, sometimes two and a half hours earlier than my normal folks, my bears. If you wanted to, right when you wake up in the morning, you could take your core body temperature, and then right after maybe 90 minutes take it again and then about 90 minutes before bed and then right as you’re going to bed. What you’ll slowly start to discover is that your core body temperature changes at very different points in the daytime and the earlier in the day that your core body temperature makes these changes, the earlier your chronotype is.” (Source)
