Co-sleeping facilitates physiological regulation and interpersonal trust between partners. Here we discuss the possibility that this effect depends on C-tactile (CT) afferents—a class of unmyelinated mechanosensory cutaneous skin nerves that underlie both parasympathetic regulation and the rewarding neurochemistry of endogenous opioids and oxytocin. The literature reports that insomnia-related problems result from an overall difficulty to de-arouse. Moreover, sleep loss is prevalent in somatosensory-poor contexts such as in Isolated, Confined and Extreme (ICE) contexts (e.g. Antarctica, Covid-19 pandemic). On this backdrop, we propose two mechanisms by which CT-afferents may moderate a touch-sleep association, that is, a long-term mechanism-dependent on epigenetic programming in the course of child development and a short-term mechanism-dependent on a CT-modulation of autonomic and endocrine processes.

同睡促进了伴侣之间的生理调节和人际信任。在这里，我们讨论了这种效果取决于 C 触觉 (CT) 传入神经的可能性 - 一类无髓鞘机械感觉皮肤神经，是副交感神经调节和内源性阿片类药物和催产素的有益神经化学的基础。文献报道失眠相关的问题是由于整体难以唤醒。此外，睡眠不足在体感较差的环境中很普遍，例如在孤立、受限和极端 (ICE) 环境中（例如南极洲、Covid-19 大流行）。在此背景下，我们提出了两种机制，通过这些机制，CT 传入可以调节触摸睡眠关联，即，
