Problemata (Problems)

And these very things bear witness; the Poet original: "ποιητὴς" (poiētēs); likely referring to Homer also in many places calls sleep "sweet," original: "ἡδὺν" (hēdyn) as if it were a provider of pleasure. Therefore, pleasure is a diffusion original: "διάχυσις" (diachysis); a spreading out or loosening of the body's substance of the body. Sleep nos produces this, though not by being relaxing, but rather, as the Methodists Methodikoi: an influential school of ancient medicine that viewed health and disease through the "pores" of the body, focusing on whether they were too constricted or too relaxed believe, sleep nos is a sort of thickening original: "πυκνωτικός" (pyknōtikos); a compacting of the body's tissues.

But digging and suspension original: "αἰώρα" (aiōra); a therapeutic technique involving swinging or being suspended in a hammock-like device to balance the body's humors are also relaxing. And when these are undertaken, in what way do people become fluid? It happens to those resting after dancing original: "ὀρχηστικήν" (orchēstikēn). Thus, from these examples, one might conclude that sleep is indeed more of a relaxant than a mere provider of pleasure.

Or, it must be said regarding this that pleasure is not an essential attribute of sleep; rather, it happens that while sleep is occurring, pleasure arises because the bodies are being restored to their natural state. For example, it becomes a release of the fatigue original: "κόπου" (kopou) from the parts that were awake.

Moreover, one can find here that not every pleasure occurs through the diffusion of the body. For even a dry tension? happens in this way, since dryness produces a thickening.
