Nonpharmacological treatment for sleep disorders are all of the following except:

A. Reading before bed (if done in a calming environment and with proper lighting) is a common nonpharmacological strategy to promote relaxation and sleep. B. Relaxation techniques, such as deep breathing and progressive muscle relaxation, are well-established nonpharmacological methods for improving sleep. C. Cognitive Behavioral Therapy (CBT) is a first-line, evidence-based treatment for chronic insomnia and other sleep disorders. D. Nonpharmacological treatments are NOT considered a last line treatment—they are often recommended first, especially for older adults, due to fewer side effects and better long-term outcomes.
