Why stress turns your pain up to eleven

Hi,

Confession: I used to think it was a coincidence.

Guests come in for chronic pain, old injuries, a back that's held a grudge since 2014, and they'll mention, totally casually, that the pain always seems to throw a party the exact same week everything else falls apart. Big deadline, sick kid, in-laws visiting, and suddenly the pain shows up too, like an uninvited houseguest who heard there was drama. I used to just nod and think, huh, bodies are weird.

Bodies aren't weird. They're just paying very close attention.

Researchers at Washington University School of Medicine in St. Louis found the actual switch. Turns out the same brain region running your stress alarm, the locus coeruleus (say that five times fast, I dare you), also works as the volume knob for chronic pain. Normally, tiny receptors on those cells act like brakes, keeping pain signals in check after an injury. Stress shows up and quietly disables the brakes. The alarm keeps blaring, the brakes stay off, and your pain gets louder, not because anything actually got worse, but because the control room upstairs is having a moment.

They tested it in mice: restore the brake receptors, pain drops back down. Take them away, pain climbs right back up. Same nerve, same injury, wildly different volume, all from one switch.

Full disclosure: mice, not people, nobody's handing out a pill for this yet. But the mechanism is real, published this month in Current Biology, and it finally gives a straight answer to something I hear constantly: is my pain actually worse when I'm stressed, or does it just feel that way?

Yes. Both. Correct on all counts. It feels worse because it is worse, your brain's just not sending you the memo.

The Weekly Reset

Here's this week's practice, the one thing I'd actually ask you to try.

Next time pain flares, jaw clenches, stomach knots, back starts complaining again, try this before you reach for anything else: breathe in for four counts, out for six or seven, five times in a row. Yes, it's just breathing. No, I'm not going to dress it up as more complicated than that.

It won't fix a herniated disc, believe me, I wish. But it talks directly to the same alarm center this whole study is about, and calming that thing down turns the volume dial the other way too.

This week's line to carry with you: I don't have to earn relief.

For the ones working overtime right now

Colorado is in the middle of one of its toughest wildfire seasons in years. The crews and first responders carrying the heaviest part of it are pulling hours most of us never see, and burnout climbs fast on stretches like this.

We've kept a discounted float rate with 911 Overwatch running for exactly this reason. If that's you, or someone you love, it's there whenever it's needed, no occasion required.

The study that found your brain's volume knob for pain

Washington University School of Medicine identified receptors in the brain's stress and alert center that act as brakes on chronic pain signals. Published August 17 in Current Biology, tested in mice so far, with real promise for pain treatment that targets the brain instead of the whole body.

The back-to-school stress numbers, if you want to feel less alone

Understood.org found 87 percent of parents feel stress or anxiety around back-to-school season, climbing to 94 percent for parents of neurodivergent kids. The survey's a few years old, but every fall since has proven it right.

This week's meditation

A free, guided practice worth carrying into your week, hand-picked from a source we actually trust.

Body Scan for Sleep, by UCLA's Mindful Awareness Research Center

Fourteen minutes, completely free, no app subscription required. You lie down and slowly walk your attention through your body, which sounds simple because it is, and that's exactly why it works when your brain's alarm system won't quit. Fitting, given everything above.

Give yourself an hour

Book a float this week, in Denver or Fort Collins. Or just try the three-second pause today and see what you notice.
