McGill University study links upright posture to improved mood and decision-making

Researchers at McGill University have found that sitting upright can subtly improve mood and decision-making abilities, even when individuals are unaware of their posture changes.

In a study involving nearly 200 participants, researchers used a virtual balloon-inflating task to measure risk-taking. Those encouraged to sit upright through adjustable workstation settings took more effective risks, earning higher rewards without increasing their failure rate. These participants also reported more positive emotions, such as pride, compared to those in slouching or control groups.

Senior author Jorge Armony noted that while the effects were modest and observed in a laboratory setting, the findings highlight the body’s influence on behavior and mental state. The research suggests that workstation design and everyday environments may play a role in shaping confidence and emotional well-being.
