As Skoltech Neuro Professor Philipp Khaitovich explains, when stress levels peak, a familiar show can offer a comforting anchor because viewers already know every plot twist, conflict, and resolution.
"When a person is stressed, the brain prefers to rely on something where its predictions are guaranteed to work out. In a new, uncertain situation with an unfamiliar plot, it's anyone's guess whether your predictions will pan out or fall flat again."
Professor Khaitovich views rewatching old favorites not as a mindless habit, but as a genuinely effective way to lower anxiety. The key is not to hide from reality indefinitely — after a cozy mental break, the brain still has to jump back into tackling real-world challenges.
