Understanding the Inseparable Link Between Mind and Body

Sleep hygiene, perhaps the most underrated aspect of physical health, is heavily influenced by psychological interventions. Insomnia is frequently a byproduct of "cognitive arousal"—the inability to quiet the mind at night. Psychology introduces Stimulus Control Therapy and sleep restriction techniques to retrain the brain to associate the bed with rest rather than ruminative thought. By addressing the anxiety surrounding sleep, psychology ensures the body can enter the deep, restorative stages of the sleep cycle where tissue repair, growth hormone release, and toxin clearance in the brain occur, thus preventing neurodegenerative diseases and systemic inflammation.
