睡眠、日常麻木和冬眠被认为是同源过程。然而，在从冬眠中周期性苏醒的过程中，地松鼠大部分的恒温期都处于非快速眼动睡眠中。因此，有人提出，动物会定期从冬眠中醒来，以从冬眠期间发生的睡眠剥夺（SD）中恢复过来。我们在 Djungarian 仓鼠中证明，脑电图慢波活动（脑电图功率密度在 0.75-4-Hz 范围内）在 SD 后增加，在日常麻木发作后以类似的方式增强。结果支持这样的假设：日常的麻木状态与睡眠的恢复功能不相容。
Sleep, daily torpor and hibernation are considered to be homologous processes. However, during periodic arousals from hibernation, ground squirrels spent most of the euthermic period in non-REM sleep. Therefore, it has been proposed that animals arouse regularly from hibernation to recover from a sleep deprivation (SD) incurred during hibernation. We demonstrate in the Djungarian hamster that EEG slow-wave activity (EEG power density in the 0.75-4-Hz range), which is increased after SD, is enhanced in a similar way after an episode of daily torpor. The results support the hypothesis that daily torpor is incompatible with the restorative function of sleep.
