摘要：
An object of the present invention is to provide a sleep determination apparatus, a sleep determination method, and a sleep determination program that provide an accurate and detailed determination of a sleep stage.
A sleep determination apparatus of the present invention comprising: a heart rate data obtaining means for obtaining, based on data regarding a heart rate of a body of a user, a very low frequency component (VLF), a ratio of a low frequency component (LF) to a high frequency component (HF), a mean heartbeat interval (RRI), and a standard deviation of each heartbeat interval (RRI) of the heart rate as heart rate variability parameters indicating a heart rate state; and a sleep state determining means for determining which of the first non-REM sleep stage or the second non-REM sleep stage the heart rate variability parameters of the user indicate, in accordance with a first determination condition that is set based on a correlation between the heart rate variability parameters and the first non-REM sleep stage and a second determination condition that is set based on a correlation between the heart rate variability parameters and the second non-REM sleep stage.
