The discovery of sleep

The discovery of sleep involved decades of research revealing that sleep is a vital, active biological process regulated by specific areas in the brain. Scientists identified regions like the hypothalamus and studied brain activity patterns to understand how the brain transitions between wakefulness and sleep. They found that sleep is essential for restoring brain function, memory, and overall health. Advances in technology, such as EEG, helped track electrical activity during sleep stages, solidifying its importance as a distinct and necessary part of human life rather than a passive state.
