From a neuroscience perspective, insomnia involves complex interactions within the brain, including alterations in brain wave patterns and imbalances in neurotransmitters.
Brain wave patterns play a crucial role in regulating sleep. During the sleep cycle, the brain transitions through different stages, each associated with distinct brain wave frequencies. These stages include wakefulness (beta waves), drowsiness (alpha waves), light sleep (theta waves), deep sleep (delta waves), and rapid eye movement (REM) sleep. Insomnia can be associated with disruptions in these patterns, such as increased beta activity or reduced slow-wave (delta) activity, preventing individuals from entering restorative sleep stages.
