Psychologist Rafael Santandreu asserts that the majority of insomnia cases stem from psychological rather than physiological causes. He identifies a common error – calculating hours of sleep remaining before waking – as a key contributor to a vicious cycle of sleeplessness. This pre-sleep calculation generates anxiety and prevents relaxation, hindering the ability to fall asleep. Santandreu emphasizes that addressing the underlying mental factors, including fear and worry, is crucial for overcoming insomnia. He suggests focusing on managing these mental obstacles rather than solely concentrating on sleep duration. The psychologist’s insights highlight the importance of a cognitive approach to treating sleep disturbances. Ultimately, breaking the cycle requires shifting focus away from anticipating wake-up time and towards calming the mind.
