THE BODY HAS ALWAYS KNOWN
New science confirms what the earth has been offering all along.
I love when I come across studies like this one.
Published this month in Nature, researchers at Columbia University built 23 biological aging clocks across 17 organ systems — heart, lungs, brain, liver, immune tissue — and measured how sleep duration affected each one. What they found was striking in its precision.
Both too little and too much sleep accelerate biological aging across nearly every organ in the body. The sweet spot for minimal aging? Between 6.4 and 7.8 hours per night.
Not 9. Not 5. The body wants rhythm. Consistency. A particular quality of rest.
The U-Shaped Curve
The researchers called it a "U-shaped pattern" — and it held across every organ system they measured. Short sleep (fewer than 6 hours) was linked to accelerated aging, depression, anxiety, obesity, type 2 diabetes, hypertension, and heart arrhythmias. Long sleep (more than 8 hours) carried its own risks — particularly through what they called the "adipose clock," influencing systemic inflammation and late-life depression through a different biological pathway.
What struck me most was this from the study's lead researcher: "Sleep is a deeply embedded part of our entire physiology, with far-reaching implications across the body."
Not just the brain. Every organ. A coordinated intelligence, asking for the same thing: rest that is neither starved nor forced.
What the Medicine Already Knew
I work with Amanita muscaria — an ancient and often misunderstood mushroom with a profound and direct relationship to the central nervous system.
Amanita muscaria contains muscimol, a compound that binds directly to GABA receptors in the brain and body — the same receptors responsible for calming neural activity, reducing the charge of the stress response, and allowing the nervous system to shift out of vigilance. This is not sedation. This is the body being given permission to exhale.
When the CNS is no longer braced, something remarkable happens. The body remembers how to drop into its own depth. Sleep becomes less effortful. Dreams become more vivid and accessible. The repair work the body has been trying to do — the work this Columbia research is measuring in organs and tissue — actually has the conditions it needs to happen.
Unlike compounds that override the body's natural rhythms, Amanita muscaria works with the intelligence already present. It quiets the noise enough for that intelligence to lead.
That is exactly what I watch happen with this medicine when it is met with the right intention and container.
Two Different Pathways to the Same Place
One of the most nuanced findings in the study was this: short and long sleepers arrive at the same destination — late-life depression — through different biological roads. Short sleepers via a more direct pathway. Long sleepers through the brain and fat tissue clocks, suggesting something systemic and inflammatory is happening beneath the surface.
This matters. Because it means the intervention can't be the same for everyone. More sleep isn't always the answer. Better conditions for rest might be.
That's a reframe I find deeply familiar in the work I do. We're not managing symptoms. We're restoring the conditions that allow the body's own intelligence to move.
What You Can Do
The research won't tell you to work with plant medicine. But it will tell you to take sleep seriously — not as a productivity variable, but as a whole-body biological event that shapes how every organ in your body ages.
A few things that genuinely support that quality of rest:
Consistent sleep and wake times (the body loves a rhythm)
Reducing stimulation in the final 60–90 minutes before sleep
Nervous system regulation practices in the evening — breathwork, gentle movement, warm water
Working with what soothes your particular system
Some of us need support getting out of the vigilance state enough to actually rest. That's not weakness — that's the imprint of a world that has asked us to stay switched on for too long.
The earth has something to offer there. It always has.
