What is a primary function of sleep according to the Restoration Theory?

The Restoration Theory posits that one of the primary functions of sleep is to enable recovery and repair of the body. During sleep, various physiological processes that contribute to physical health and restoration are enhanced. This includes the release of growth hormones, repair of tissues, and bolstering of the immune system. Furthermore, sleep stages, particularly deep sleep, are integral to physical recovery, where metabolic processes slow and restoration occurs at the cellular level.

While learning and memory, emotional processing, and relaxation are important aspects of sleep, they do not encapsulate the core focus of Restoration Theory. The theory emphasizes the necessity of sleep to rejuvenate the body physically, making it essential for overall health and well-being.
