The best posture is your next posture

People who change their posture have easier necks than people who guard it

Key points in 30 seconds

1. Not being able to hold good posture isn't a sign of weak willpower. Your body was never built to "hold" a position in the first place.
2. Any posture becomes a bad posture if you hold it too long. Even the textbook upright posture. The only thing that changes is where the strain builds up.
3. When you stand for a long time, you shift from one leg to the other. When you sit for a long time, you fidget without thinking. Fidgeting isn't a bad habit. It's how your body is designed.
4. The evidence for policing your angles is weaker than you might think. We still don't know whether forward head posture causes pain, or pain causes forward head posture.
5. The clear evidence lies elsewhere. In an analysis of 27 clinical trials, what reduced chronic neck pain wasn't holding a posture, but exercise that builds strength.

What we often hear

• "I stuck a note on my monitor that says 'sit up straight.'"
• "I got a new chair and even installed a posture reminder app."
• "The more I think about sitting up straight, the stiffer my shoulders get."
• "I keep wondering why I can't even hold one good posture."

Today's post is about letting go of that self-blame.

You can't hold good posture not because your willpower is weak, but because your body was never built to "hold" a position in the first place.

Any posture becomes a bad posture if you hold it too long

That goes for the upright posture you'd see in a textbook, too. When you stay in one position for a long time, the same muscles keep working and strain keeps building up on the same joints.

Sitting up perfectly straight for three hours and slouching for three hours differ only in where the strain builds up. Either way, it builds up.

Your body isn't a machine designed to hold one correct posture. It's a living thing designed to keep shifting positions and spread the load around.

The proof: when you stand for a long time, you end up shifting from one leg to the other, and when you sit for a long time, you start fidgeting on your own. Fidgeting isn't a bad habit. It's how your body is designed.

"But isn't it a big deal if I end up with forward head posture?"

Research does have something to say about that worry.

In an analysis that pooled 15 studies measuring the link between posture and neck pain, adults with neck pain had heads that sat forward by an average of 4.8 degrees more.

But among teenagers, who look at smartphones the most, there was no link between posture and pain. And above all, the direction hasn't been settled: we don't know whether forward head posture causes pain, or pain causes forward head posture. We've covered that topic separately.

So the effort you spend checking your angles in real time rests on weaker evidence than you might think.

On the other hand, some things do have clear evidence. In an analysis of 27 clinical trials, what reduced chronic neck pain wasn't holding a posture, but exercise that strengthens the neck, shoulders and shoulder blades.

To sum up: constant posture-policing has weak evidence, while switching positions and building strength make sense and have evidence behind them.

That's why our posture prescription isn't "sit up straight." It's this.

One: use a "posture menu" instead of one "correct posture"

Sitting upright, leaning back against the chair, standing to work for a bit, even crossing your legs as long as you switch sides.

Put them all on the menu and rotate through them. With the rule that any posture is fine as long as it's not for too long, you're freed from the fatigue of policing your posture, and the load spreads out on its own.

Two: create cues to switch

If you try to remember through willpower alone, you'll forget the moment you get focused. The trick is to build the cues into your surroundings.

An alarm that goes off before the hour is up. Using a small cup on purpose, so you get up often to refill it. Standing up when you take phone calls.

You don't need to do anything special once you're up. The change in posture is the whole point.

Three: go the opposite way once a day

If you've spent all day hunched toward a screen, do at least one movement a day that opens your body the other way. A big stretch, chest open and arms pulled back, is enough.

It's a quick trip in the opposite direction from where the strain has been building.

Four: and build strength

If switching positions is the defense that spreads the load, strengthening exercise is the offense that builds the capacity to handle it.

Start with things like holding your hand against your head and pushing against each other, or squeezing your shoulder blades together.

Which exercises to do and how much depends on the condition of your neck, so we set the method and number of reps with you at your visit and check on it next time.

But if you have these signs, it's not about posture

Numbness or weakness that travels down your arm, pain that started after an injury, or pain that gets worse at night even when you rest.

In these cases the problem may not be a habit, so checking the nerves and structures comes first. When needed, we also check first, in partnership with the radiology clinic on the 2nd floor of the same building.

If you're already in pain

The order is the same. Before blaming posture, we find the cause. We use acupuncture, pharmacopuncture (herbal acupuncture) and Chuna (Korean manual therapy) to address the pain and stiff movement so your body can move again. Then we compare your starting point, measured with a posture analysis, against changes in your pain and movement, in numbers.

We don't promise angles. The goal isn't a perfectly straight photo. It's a day without pain.

If you're looking into posture correction bands, take a look at that post too. The order in which we examine the neck is laid out in our treatment guide.

Change your sticky note today

An afternoon where you get absorbed in your work without thinking about posture, and get up lightly when the alarm goes off. A commute home that doesn't feel heavy, even without a "sit up straight" note. That's what we're aiming for.

The exercises you need, and the pace, differ from person to person depending on your body. But what you can change today is the same.

Take that sticky note off today. And put up a different one in its place: "Get up."
