Using a large sample of 247 male participants, natural winners and losers of a physical competition were randomly assigned to hold a low, neutral or high-power postural display. Power displays naturally occur within the context of competitions, as do changes in hormones, and researchers have yet to examine the effects of poses within this ecologically relevant context. The effect of postural power displays (i.e. power poses) on hormone levels and decision-making has recently been challenged. Low testosterone has been linked to increased anxiety and depression, and poor posture itself can negatively affect mental health. Incorporating small changes to your daily habits — such as standing tall, strengthening your core, and taking posture breaks — can lead to lasting improvements in both your physical and mental health. For men, improved posture can increase blood flow to the pelvic region, which is important for sexual health and function. The question remains as to whether adopting constrictive postures would lead to a change in salivary progesterone, thereby indicating an increase of affiliation motivation. Two others attempted to improve the original study’s setting by testing effects in more ecologically valid social contexts that bear implications for power, status and dominance, such as competition or public speaking (Smith & Apicella, 2017; Davis et al., 2017). Building on theories of embodiment, which postulate that many aspects of cognition are shaped by representations of body actions, Carney, Cuddy & Yap (2010) assessed whether exhibiting non-verbal dominant or submissive behavior, namely expanding or constricting one’s body, would induce corresponding changes in testosterone and cortisol levels. Saliva samples were taken at two different time points in a time window in which hormonal responses to stress, competition and other manipulations are known to be strongest. By testing the effects of repeated but short posture manipulations in between the blocks of a social task while using a cover story, it further fulfills the conditions previously raised as potentially necessary for the effects to occur. Altogether, it appears that additional empirical evidence is necessary to reach final conclusions about whether expansive and constrictive postures induce changes in testosterone or cortisol levels at different time points than assessed previously or when adopted for longer durations. Neither testosterone and cortisol levels linked to dominance behaviors, nor progesterone levels related to affiliative tendencies, responded differently to adopting expansive as opposed to constrictive postures. Despite this growing body of evidence that does not support posture effects on hormone levels, the question remains as to whether repeatedly holding postures over time and/or assessing hormonal responses at different time points would yield different outcomes. From cortisol levels to testosterone production, your posture can have a profound effect on various hormones that influence your mood, stress levels, and even your confidence. In doing so, it assessed whether larger doses of posture or collection of saliva samples at longer time intervals than previous studies would produce similar effects on testosterone and cortisol as the study by Carney, Cuddy & Yap (2010) in contrast to previous non-replications. The current study assessed whether repeatedly adopting expansive and constrictive postures known as power postures induces endocrine responses that resemble the hormonal correlates of dominance and affiliative behavior. Through chiropractic and quantum neurology care, we are able to begin the process of improving posture. This woman not only reported significant changes in pain (6/10 to 1/10), but also demonstrated improved posture. In a previous post on back pain and posture, I posted a "before" and "after" picture of a woman that had one quantum neurology correction at a tennis match. Your body language not only influences how others see you, but also how your brain regulates energy, mood, and sex drive. Still, effects were small, multiple comparisons were made, and the results ran counter to our predictions. It has been put forward that subtle differences in social context may account for the differences in results. Always consult with a healthcare provider for any concerns or symptoms you may be experiencing. Straighten up, take control, and start reaping the hormonal benefits today. So, if you’ve been feeling sluggish, weaker, or just not as sharp as you used to be, don’t ignore your posture. Your posture isn’t just about looking good—it’s about feeling good and performing at your best. The foundation of a heart-healthy diet should be minimally processed plant-based foods, which are good sources of fiber, protein, and phytonutrients. Choose the plan that fits your health goals. It’s worth mentioning that other possible reasons for high T levels in men may also include testicle and adrenal gland tumors. Eventually, professor Cuddy points out that these positive hormonal changes can make you more fearless, confident, risk-tolerant, assertive and even calmer. As with any healthcare intervention, safety should be evaluated using… Specific exercises at home are able to reinforce the corrections made in the office, and accelerate the long lasting changes in posture. Studies have shown that standing or sitting in a slouched position can lead to a decrease in testosterone levels, while adopting open and expansive postures can boost testosterone production. Conversely, closed-off postures can elevate cortisol levels and contribute to feelings of stress and anxiety. Closed, collapsed postures signal defeat and insecurity, raising cortisol and lowering your sex hormones. Harvard research on "power poses" suggests that open, upright postures can increase testosterone levels by up to 20%, while closed, hunched postures can reduce it. Research shows that bad posture can increase levels of cortisol, the stress hormone. By improving posture, you can boost testosterone production, reduce stress, and improve blood flow throughout the body.
