@Lothric Good post! After first encountering Peat's work 10 years ago, I tried to write (for myself) what an ideally designed work environment might look like, "optimized" in some sense to minimize chronic stressors or maximize opportunities to confront "peak challenge" with creativity and then "productively" adapt (hormesis). It eventually occurred to me that perhaps my question wasn't the right one, because, like you said, it assumed objective was more efficient/productive work output (using Peat-inspired principles to "work-max" or "productivity-max"). Finding experiences that provide opportunities for "wonder" is another important Peat-inspired piece of this, acknowledging how challenging it may be to find wonder in many work situations.
I don't think Peaty productivity-maxing is a bad question. Some forms of productivity (facing up to a challenge and getting things done) are good self-care and can be fulfilling in deeper ways, consistent with bioenergetic principles. The deeper consideration of leisure and self-development @Lothric mentioned is on-point: not treating leisure as recharge to make work more productive but as an end in itself (deeper structuring of one's self, including yet exceeding the domain of work).
My conclusion? Peat-inspired principles to improve work productivity can be a valuable/valid/healing/bioenergetic objective. @Lothric's point is deeper and worthwhile to consider if one can afford to. Given the high-stress work environments and socially/aesthetically-depleted environments many of us find ourselves in, a few clever Peat-inspired inventions to manage stress and increase energy can be a godsend and even more than enough to adapt and "thrive in place" (metabolically speaking, assuming some tough and unwanted constraints). If one can afford to allocate more and more energy/resources on self development beyond work, that would be a privilege and could be a life-changing opportunity toward self-possession and fulfilment on the deepest levels. Meantime, a few Peat-inspired changes in perspective/behavior/diet/activity can make a massively positive difference even when constrained to "staying stuck" in an environment one wishes they could change but can't. Cope? Maybe. Worthwhile/life-saving/meaningful although imperfect? Yes.
