Psychology says people who can't sleep without a blanket even when it's hot are not strange: Why the brain associates it with safety, comfort and emotional regulation

Psychology suggests that adults who cannot sleep without a blanket, even in warm weather, are rarely being irrational. More often, they are responding to years of learned associations that connect blankets with comfort and security. For many people, a blanket is more than a physical object. It symbolizes familiarity, consistency, and a sense of safety that helps the brain relax before sleep.
