A neuroscientist’s guide to how stress affects your body.

The Brief
Welcome back, Wellworthy readers.
Everyone is trying to reset their nervous system.
From poor sleep to burnout to feeling overwhelmed, more and more symptoms are being linked to the body’s stress response.
But the regulation hype might be outpacing the science.
Today, we’re breaking down what actually happens when stress hits — and what you can do about it.
Here’s what’s inside:

The Breakdown
Social media is full of content about “nervous system dysregulation,” referring to everything from anxiety to poor sleep.
But neuroscientist Dr. Dave Rabin says the term is being overused. Nervous system dysregulation isn’t a diagnosis, and feeling stressed doesn’t automatically mean something is wrong.
“Your nervous system is supposed to respond to stress,” Rabin says. “That’s not dysfunction. That’s biology working as designed.”
Here’s what he says is worth knowing:
Look for a pattern, not a bad week. Trouble sleeping, constant tension, difficulty sleeping, or being unable to relax may signal that your body isn’t getting enough recovery. Rabin says resilience isn’t about avoiding stress. It’s about being able to calm down once the stressful moment has passed.
Your body registers safety before your mind does. Rabin says slow breathing, soothing touch, rhythm, and connection can help your nervous system settle. That’s why something as simple as a hug can make a difference within seconds.
Keep it simple. Stepping outside, stretching, listening to music, playing with a pet, or getting a hug can help your body settle. Some shifts can happen within minutes, but repetition makes it easier to recover over time.
The takeaway
Stress is inevitable, but how you respond matters. Instead of chasing a perfectly calm nervous system, find one small practice that helps your body return to baseline. As Rabin puts it, “Regulation will then become something you experience rather than another performance metric.”
