This perspective aligns perfectly with scientific models of sleep, notably the Spielman '3P' model, which shows how behavioral factors perpetuate insomnia. Research confirms that the brain can associate the bed with anxiety and a state of alertness rather than rest, creating harmful conditioning. A meta-analysis of randomized controlled trials (RCTs) published by the American College of Physicians in the Annals of Internal Medicine confirms that behavioral approaches targeting this conditioning are the most effective in the long term. While it is true that the sleep mechanism is not physically 'broken' in the majority of people, there are nonetheless biological predispositions to nervous hyperactivity that should not be completely overlooked. The creator's statement remains scientifically sound and encouraging, reminding us that we can reprogram our nights by changing our mental relationship with sleep.
