When Your Body Finally Gets Permission to Rest
How chronic fatigue, disrupted sleep, and years of overwork resolve, and what light had to do with it
A Moment with Dr. Stillman
He was the kind of person who never stopped. For years, he carried a full clinical practice, showed up to serve his congregation every week, and pushed through fatigue that most people would have taken as a warning sign. He told himself he could keep going. And he did, until he couldn’t.
The crash, when it came, was severe. His nervous system was so dysregulated he couldn’t track what his hands were doing. His heart rate was elevated even at rest. He was waking multiple times each night, arriving at mornings agitated and exhausted, barely functional. He had to step back from the work he loved.
He was the one who held things together for everyone else. The disruption in his own health cost him the ability to do that.
If that sounds familiar, the exhaustion you’ve been outrunning, the mornings you wake up feeling worse than when you went to bed, the sense that your body is running a deficit you can never quite pay off, keep reading.
What I Found When I Looked Closer
When I reviewed what he’d been dealing with, the picture was consistent:
Fatigue that had been building for years before the acute crash
Sleep that wasn’t restorative, with frequent waking and elevated heart rate through the night
Waking in a state of agitation rather than calm
No structural disease found to explain it, just a system running on empty
He had seen other providers. He had made lifestyle adjustments. He was not someone who ignored his health. But the foundation had been quietly eroding for a long time.
What I noticed was that his body had essentially stopped recovering at night. Not because of a single dramatic cause, but because years of sustained overwork had depleted his repair margin to nearly zero. His waking heart rate on his tracking device was regularly elevated by more than 20 points above baseline. His sleep scores were in the low 60s. These were not numbers for someone who was simply tired. These were numbers for someone whose nervous system had forgotten how to downshift.
Within about five to six weeks of addressing foundations, including his light environment, his mineral status, and his pace, his tracking metrics began to normalize. Sleep scores climbed back into the high 70s. He stopped waking agitated. He described mornings as calm. By early spring he was snowshoeing uphill and wearing out a high-energy dog on daily walks.
We were still working on some pieces. But the trajectory was clear.
What Nobody Had Looked For
The thing most people miss in cases like this is the role light plays in recovery.
Not light therapy as a single intervention, but light as a fundamental input. The signal your body uses to know when to be alert and when to repair. When that signal is disrupted, night after night, the body loses its repair window. Inflammation accumulates. The nervous system stays primed. Sleep becomes lighter and less restorative. Over time, the repair deficit compounds.
In my practice, I treat light as a foundation, not an optional add-on. Specific wavelengths of red and infrared light support mitochondrial function, which is how cells generate energy for repair. But equally important is the timing of light. Bright, natural light in the morning to anchor the circadian clock, and reduced artificial light after dark to allow melatonin and restoration to do their work.
In cases like his, years of accumulated overwork, mineral depletion from sustained stress, a nervous system stuck in alert mode, the Therapeutic Tree points clearly toward foundations first. Before we look at more complex interventions, the question is always whether the repair window is open. Whether the body is actually able to use the night to heal.
In his case, the answer had been no for a long time. Addressing that was the turning point.
“The eye is the lamp of the body. If your eyes are healthy, your whole body will be full of light.” — Matthew 6:22
Three Things To Explore This Week
Notice your morning state. How do you feel within the first 15 minutes of waking? Calm and oriented, or wired and agitated? This is one of the clearest indicators of how well your nervous system recovered overnight. Many people accept agitated mornings as normal. In my experience, when foundations improve, this often shifts within one to two weeks.
Fix your light exposure after dark. For three to four days, simply notice how much artificial light you’re exposed to in the two hours before bed, including screens, overhead lighting, and devices. Cut your artificial light exposure as much as possible, without tripping over things in the dark. Use blue blockers and change screen settings to protect your circadian rhythms.
Consider whether pace is part of your problem. His crash wasn’t random. Years of sustained output without adequate recovery left his system running at a deficit long before the acute episode. If you are the one everyone else leans on, the one who keeps going because stopping feels irresponsible, this is worth sitting with. Stewardship of the body is a long game. In my experience, patients who adjust pace before the crash recover far faster than those who wait.
Where to Go From Here
The body has remarkable capacity to restore itself when you give it what it needs and stop taking away what it requires to repair. For this man, reclaiming his mornings and rebuilding his repair window made it possible for him to return to his work, his service, and his life. That is not a small thing.
