• Risk-taking increased gradually rather than all at once — The researchers used a task that required participants to inflate virtual balloons, with each additional pump increasing both the possible reward and the chance that the balloon would burst. Participants could stop and collect their earnings at any point. Both posture groups became more willing to pump the balloons as the experiment progressed, but that increase was noticeably steeper in the expansive group.

That time pattern is important. The groups didn't simply begin the experiment with dramatically different behavior. Instead, their choices separated progressively across repeated decisions. The difference between groups across trials was statistically significant, and a second analysis of how risk-taking changed over time supported the posture effect.

• Greater risk didn't translate into worse performance — Taking more risk sounds negative, but the results were more nuanced. Researchers examined not only how far participants pushed the balloons but also how often balloons burst and how much money participants earned. This allowed them to distinguish greater willingness to accept risk from simple carelessness.

The expansive group earned more overall, while the number of exploded balloons didn't differ between groups. In practical terms, the more upright participants weren't simply clicking recklessly. They accepted more risk without suffering more failures on the task, suggesting that posture influenced the way they balanced risk against reward.

• Actual neck position mattered more than a simple posture label — Mood results also revealed an important distinction. The researchers didn't find a straightforward overall effect in which everyone assigned to the expansive setup automatically felt better. Instead, actual neck angle helped explain changes in pride.

Neck angle also predicted changes in emotional valence — essentially, how positive or negative participants felt. It didn't, however, predict emotional arousal, which reflects how activated or energized a person feels rather than whether those feelings are pleasant or unpleasant.

This tells you why simply commanding yourself to "sit up straight" misses part of the story. People respond differently to the same physical setup. Measuring what the body actually did captured differences that a basic upright-versus-slumped label could overlook.

• The effects remained when people didn't know posture was being tested — Most participants reported little or no awareness that the experiment was altering their posture. Researchers went a step further and repeated their analyses using only participants who reported no awareness whatsoever that tablet position was manipulating how they sat.

The general pattern for mood and risk-taking remained, although the smaller group reduced the statistical strength of some comparisons.

That finding strengthens the real-world relevance of the experiment. You don't have to consciously think, "I'm adopting an expansive posture," for your physical environment to affect how you hold yourself. The researchers specifically noted that common features such as desk height and chair ergonomics could influence mood or behavior through these subtle posture changes.

• The results are useful, but they don't apply equally to everyone yet — The researchers acknowledged several limitations. Participants came mainly from a student population in Canada, most were young women, and the study wasn't preregistered, meaning the research plan and analyses weren't formally recorded publicly before the experiment began.

The authors also noted that posture research has faced replication problems, so these results need to be viewed alongside additional studies rather than treated as definitive proof by themselves.

There was another practical complication: People slump differently. Some participants lowered their heads toward the tablet, while others leaned forward from their hips. Both counted as contracted positions under the study's neck-angle measurement, yet those positions aren't necessarily identical in how they affect you.

1. Raise your screen to support a naturally upright position — Start with the environmental factor tested in the study: screen height. If you spend hours at a computer, position your monitor so you don't have to repeatedly lower your head or bend forward to see it.

Pay attention to what your body actually does after you settle into your normal work. If your head gradually drops or your upper body folds toward the screen, your setup is still encouraging a contracted position. Adjust it until you're able to look forward comfortably without forcing yourself into a rigid pose.

2. Stop working with your laptop or tablet in your lap — A device positioned far below your natural line of sight encourages you to look down. If you regularly work from a couch, bed or chair with your device on your legs, raise it onto a stable surface that allows you to keep your head and upper body more upright.

You don't need to turn good posture into an all-day test of willpower. Make the physical environment do more of the work for you. The study demonstrated that changing tablet height was enough to naturally produce differences in how participants positioned their bodies.

3. Hold your phone at eye level instead of looking down at it — The study tested tablet height, but the same principle applies every time you check your phone. Holding it low, which is what most people do, drops your head forward and loads your neck with significantly more force than a neutral position. When you're reading, scrolling or texting, bring the phone up to your line of sight rather than dropping your chin to meet it.

Better yet, reduce the time you spend on your phone in the first place. Every minute you cut from unnecessary scrolling is a minute your neck and upper body aren't being pulled into a contracted position. It's one of the simplest ways to protect your posture, not by fixing how you hold the device, but by picking it up less often.

4. Adjust your entire workstation instead of focusing only on your neck — Your screen is only one part of the equation. Look at how your desk and chair work together because the researchers identified desk height and chair ergonomics as everyday environmental factors that influence posture.

If you're a desk worker, sit down exactly as you normally would and notice what happens without correcting yourself. Your goal isn't a stiff, exaggerated "power pose." You want a setup that makes an open, comfortable position feel natural rather than something you have to consciously maintain.

5. Stand up and take regular breaks from sitting — Even with a well-designed workstation, you don't want to remain seated in one position for hours. Stand up and take regular breaks from sitting throughout your day. Use natural stopping points — finishing an email, completing a call or wrapping up a task — as cues to get out of your chair.

If you're a desk worker, make these breaks part of your routine instead of waiting until your neck or back feels stiff. Stand, walk around briefly and change your body position before returning to work. This gives your body a simple reset and prevents good posture from becoming another form of prolonged, static sitting.

6. Support your spine while you sleep — Your posture doesn't stop mattering when your workday ends. Your sleep setup gives your spine several hours to recover from the positions you hold during the day, so arrange your bed to keep your neck and spine comfortably supported. If you sleep on your side, place a pillow between your knees. If you sleep on your back, elevate your legs with a wedge to take pressure off your spine.

Your pillow matters as well. A cervical pillow designed to support the natural curve of your neck without pushing your head too far forward can help maintain a more neutral posture during sleep. The goal is the same day and night: Shape your environment so your body doesn't have to fight against it.
