Why “Just Rest It” Might Be the Worst Advice You Can Give a Whiplash Patient
Dr Barry Marks, Chiropractor and Car Accident Injury Specialist on Why That’s Still Controversial.
If you’ve been in a car accident, someone probably told you to take it easy afterward. Rest the neck. Skip the workouts. Give it time and let the body do its thing.
That sounds like common sense. Instinct even, if something hurts, you leave it alone. But with whiplash, that instinct points people the wrong direction, and it has for years.
Here’s what the evidence actually shows.
Whiplash patients who rest too long don’t heal faster, they heal slower. They get stiffer. Their pain lasts longer. And a real chunk of them end up with chronic neck pain that drags on for months or years, pain they could have avoided with a different approach early on.
So why does resting backfire like this?
Picture a muscle that just sits there and doesn’t move. It tightens. Blood flow to that area drops, and blood flow delivers the nutrients your tissue needs to repair itself. On top of that, the muscles surrounding the injury start to guard, tensing up almost like they’re bracing for another hit. The guarding protects the area in the moment, but it increases tension in an already irritated region.
We don’t talk about another piece of this enough. Once a muscle strain or ligament sprain happens, the body starts laying down scar tissue almost right away, within hours. Keep that area immobilized, and scar tissue keeps building with nothing to check it. Leave it alone long enough, and you end up with permanent stiffness and a joint or muscle that doesn’t function the way it should.
Controlled, guided movement flips that around.
Blood keeps circulating the way it’s supposed to. The muscles don’t lock down into that guarded, defensive posture. And movement gently breaks that scar tissue loose from the muscle and joint before it can harden into a long term problem.
Recovery has a nervous system side too, and people skip right past it. After a whiplash injury, the nervous system can get overly sensitive, treating ordinary movement like a threat. Slow, guided motion retrains that response. It tells the body it’s okay to move again, and that signal matters just as much as the physical healing does.
Now, to be clear, none of this means gritting your teeth and pushing through sharp pain, or jumping back into your regular workouts a few days after the crash.
That approach can do real harm early on. What actually works is structured. Guided. Someone who understands whiplash builds a plan that increases motion in careful steps, matched to what the tissue can handle at that point in healing. Reckless activity and real rehab are not the same thing, and a lot of the bad advice out there comes from mixing the two up.
Providers who’ve spent years treating whiplash, seeing it walk through their doors week after week, build their treatment plans around exactly this principle. Not because it’s some new fad. Because they’ve watched it play out again and again: patients who move early recover better than patients who get sent home and told to wait it out.
Dr. Barry Marks has treated car accident injuries in Orange County since 1986, and his approach reflects what decades of hands-on experience with whiplash tend to teach: guided movement, started early, generally wins out over the old rest-and-wait model.
That raises a real question.
The research supports moving early. The clinicians who see these injuries most often already practice this way. So why does “just rest” remain the first thing so many patients hear?
Some of it is probably habit. Advice gets handed down from provider to provider, patient to patient, long after it stops being the right call. Some of it might be caution, a hesitation to recommend movement because it sounds riskier, even though sitting still is often the bigger risk. And some of it is just time. Telling someone to rest takes ten seconds. Walking them through a real rehab plan takes a lot longer, and not every appointment has room for it.
Whatever the reason, patients deserve advice that’s kept up with what we actually know.
