The present study aimed to characterise the relationship between sleep and interoception in two independent studies. Theoretical grounds for such a relationship include a weak relationship between subjectively- and objectively-measured sleep, the covariance of sleep with pain, as well as the mass regulation of a number of visceral biological systems. In addition, such a relationship is often reflected in our language (i.e., 'feeling' tired). In both studies (Study 1: N = 118, 73% female, mean age 20.98 years; Study 2: N = 830, 49% female, mean age 38.04 years) sleep over the last month was self-reported. Confidence in interoceptive accuracy, which is the precision with which a person can monitor visceral signals, was measured using the Interoceptive Accuracy Scale, while interoceptive attention, which is the dispositional tendency to attend to bodily signals, was measured using the Body Perception Questionnaire. Study 1 revealed a relationship between long sleep latency and low confidence in interoceptive accuracy (β = -0.222, p = 0.021) and poor sleep quality and less interoceptive attention (β = -0.226, p = 0.016). Study 2 replicated these results as well as made clear a more general pattern whereby poor sleep-characterised by short duration, poor quality, less efficiency, long latency, and more frequent nighttime awakenings-related to an interoceptive phenotype of less confidence in interoceptive accuracy and more interoceptive attention (all β ≥ 0.047, p ≤ 0.17). In conclusion, results from these two independent studies provide robust cross-sectional evidence for associations between various dimensions of poor sleep and greater interoceptive attention, but less confidence in interoceptive accuracy.
本研究旨在通过两项独立研究来描述睡眠与内感受之间的关系。这种关系的理论依据包括主观测量睡眠与客观测量睡眠之间的弱相关性、睡眠与疼痛的协方差，以及多个内脏生物系统的整体调节。此外，这种关系常常反映在我们的语言中（例如，“感觉”疲惫）。在两项研究中（研究1：N = 118，73%为女性，平均年龄20.98岁；研究2：N = 830，49%为女性，平均年龄38.04岁），均通过自我报告获取过去一个月的睡眠情况。使用内感受准确性量表测量对内感受准确性的信心，即一个人监测内脏信号的精确程度，而使用身体感知问卷测量内感受注意力，即关注身体信号的倾向性。研究1揭示了长睡眠潜伏期与低内感受准确性信心之间的关系（β = -0.222，p = 0.021），以及睡眠质量差与内感受注意力较少之间的关系（β = -0.226，p = 0.016）。研究2重复了这些结果，并明确了一种更普遍的模式，即睡眠差（以睡眠时间短、质量差、效率低、潜伏期长和夜间觉醒频繁为特征）与内感受准确性信心较低和内感受注意力较多的内感受表型相关（所有β≥0.047，p≤0.17）。总之，这两项独立研究的结果为睡眠差的各个维度与更高的内感受注意力以及更低的内感受准确性信心之间的关联提供了有力的横断面证据。
