Human physiological systems have a major role in maintenance of internal stability. Previous studies have found that these systems are regulated by various types of interactions associated with physiological homeostasis. However, whether there is any interaction between these systems in different individuals is not well-understood. The aim of this research was to determine whether or not there is any interaction between the physiological systems of independent individuals in an environment where they are connected with one another. We investigated the heart rhythms of co-sleeping individuals and found evidence that in co-sleepers, not only do independent heart rhythms appear in the same relative phase for prolonged periods, but also that their occurrence has a bidirectional causal relationship. Under controlled experimental conditions, this finding may be attributed to weak cardiac vibration delivered from one individual to the other via a mechanical bed connection. Our experimental approach could help in understanding how sharing behaviors or social relationships between individuals are associated with interactions of physiological systems.
人体生理系统在维持内部稳定方面发挥着重要作用。先前的研究发现，这些系统受与生理稳态相关的各种类型的相互作用调节。然而，不同个体的这些系统之间是否存在任何相互作用尚不清楚。本研究的目的是确定在相互关联的环境中，独立个体的生理系统之间是否存在任何相互作用。我们调查了同睡者的心律，发现有证据表明，在同睡者中，不仅独立的心律会在相同的相对相位长时间出现，而且它们的出现存在双向因果关系。在受控实验条件下，这一发现可能归因于通过机械床连接从一个个体传递到另一个个体的微弱心脏振动。我们的实验方法有助于理解个体之间的共享行为或社会关系如何与生理系统的相互作用相关联。
