Slumped posture is a diagnostic feature of depression. The negative thinking or low level of energy can harm us in more ways than one. Some research studies had stated earlier that good posture can work wonders in boosting one's confidence, mood and energy levels
According to the study, adopting an upright posture may increase positive affect, reduce fatigue, and decrease self-focus in people with mild-to-moderate depression.
These studies suggest that, compared to sitting in a slumped position, sitting upright can make you feel more proud after a success, increase your persistence at an unsolvable task, and make you feel more confident in your thoughts said Elizabeth Broadbent, one of the authors of the study. "Research also suggests that sitting upright can make you feel more alert and enthusiastic, feel less fearful, and have higher self-esteem after a stressful task.
The researchers conducted a study involving sixty-one community participants who screened positive for mild to moderate depression. The effects of physiotherapy tape on cognitive function were monitored. They were randomised to sit with usual posture or upright posture and physiotherapy tape was applied. Participants completed the Trier Social Stress Test speech task. Changes in affect and fatigue were assessed. The words spoken by the participants during their speeches were analysed.
It was found that postural manipulation significantly improved posture and increased high arousal positive affect and fatigue compared to usual posture. This preliminary study suggests that straightening your posture can have beneficial effects.
