Chemotherapy is a physically and emotionally demanding treatment, and one of the most commonly overlooked side effects is disrupted sleep. Many patients find that their sleep patterns change significantly during treatment—even when they feel exhausted.
Some people struggle to fall asleep, others wake frequently during the night, and some experience a constant sense of fatigue without restorative rest. These changes are real, common, and influenced by multiple factors.
Understanding why sleep is affected during chemotherapy can help patients feel more in control and identify strategies to improve rest during treatment.
