Probing the embodiment of sleep functions: Insights from cardiac responses to word‐induced relaxation during sleep.

The article "Probing the embodiment of sleep functions: Insights from cardiac responses to word-induced relaxation during sleep" published in the Journal of Sleep Research explores the relationship between bodily functions, particularly cardiac activity, and cognitive functions during sleep. The study suggests that the presentation of relaxing words during non-rapid eye movement (NREM) sleep can lead to an increase in slow-wave sleep duration and subjective sleep quality. The research findings indicate that cardiac activity slows down in response to word-induced relaxation during NREM sleep, highlighting the importance of considering bodily signals in understanding sleep functions. The study aims to promote the investigation of cardiac responses in sleep research to provide a more comprehensive understanding of sleep functions and their modulation by sensory stimulation.
