Nature Does Not Hurry — And Neither Should You: The Biology of Rest and Rhythm
Aug 26, 2026💭 Go deeper: We talk more about this in episode #282 of the Joy Lab Podcast
Humans, it turns out, are made to be active. And to rest.
For example, your brain is built to sustain focused concentration for roughly 60 to 90 minutes before productivity starts to drop. Most of us know this intuitively: the spaciness, the small mistakes, the reach for caffeine or sugar that doesn't actually fix the problem. What the body is asking for is a break. Even just fifteen or twenty minutes.
Henry Emmons, MD, calls this managing energy rather than time and he also thinks of it as a mindfulness practice. You have to actually notice when you're starting to fade.
Here's another example: Cortisol rises and falls across the day in a pattern designed to support focus in the morning, a natural rest dip after lunch, a mid-afternoon rise, and a long evening decline into sleep. Depression, Henry argues, can be understood in part as this system getting out of sync. When chronic stress pushes cortisol into overdrive, the whole rhythm can get disrupted... including the classic 3 AM wake-up, when the early-morning cortisol surge gets a running start and pulls you out of sleep before you're ready.
A key protective way to manage your energy is to get good sleep. People with depression who improve their sleep double their chances of recovery. People without depression who develop sleep problems double their risk of becoming depressed. Sleep is, in Henry's words, probably the best mood stabilizer available.
And then there are the longer infradian cycles (e.g., menstruation, seasonal changes) where tracking the patterns can transform what feels like depression arriving out of nowhere into a predictable, and hopefully more manageable rhythm.
When we can tune into all of these different cycles, rather than fighting them, we can step into a more connected flow of energy. We can rest and restore when needed, and we can get up and get active as well.
As Lao-Tzu said: "Nature does not hurry. Yet everything is accomplished.
