Sleep and Wakefulness

Sleep and wakefulness are states of consciousness that regulate our overall health. Wakefulness is when your brain is alert, processing information, and engaging with your environment. Sleep is a restorative state where your body and brain recover, consolidate memories, and support essential functions like immune function and tissue repair. Sleep cycles through different stages, including light sleep, deep sleep, and REM sleep. These stages help optimize physical and mental health. Maintaining a regular sleep-wake schedule ensures the body’s biological clock stays aligned, supporting alertness during the day and restful sleep at night.
