Sleep was naturally selected because it created a period in which the body could rest and repair itself, increasing survival chances. Which theory describes this idea?

• A. Restoration theory
• B. Adaptive theory
• C. Evolutionary theory
• D. Circadian theory

Answer: (A)

Sleep's restorative function is the idea being tested. The restoration theory holds that sleep provides time for the body to repair tissues, replenish energy stores, and clear metabolic byproducts, supporting overall physiological health and immune function. This repair-focused view explains how sleep boosts survival by keeping the body's systems ready and capable. Adaptive theory, on the other hand, suggests sleep evolved to conserve energy and reduce exposure to danger, not primarily to repair the body. Circadian theory centers on the timing of sleep with our internal clock and daily rhythms, rather than on restoration. Evolutionary theory is often used similarly to adaptive theory, but it doesn’t specifically emphasize bodily restoration as the main reason sleep enhances survival.
