Indeed, there is evidence that treating dyads (again, as opposed to the individuals therein) as a dynamic functional unit yields therapeutic benefits across a number of health-relevant domains including diabetes and blood glucose monitoring (Anderson et al 1997;Berg et al, 2013), sleep apnea (Baron et al, 2011), arthritis (Hemphill et al 2016), pain management (Wilson et al, 2017), and aging (Rauers, Riediger, Schmiedek, & Lindenberger, 2011). 12 Crucially, we are able to claim that health and disease can extend to include symbiont microbes, parents, or spouses without sliding into the claim that health must also extend to include the advertising industry, cultures of consumption, oppressive economic practices, etc.…”
