Nocturia is the main way diuretics disrupt sleep. By increasing urine production, especially when taken later in the day, these medicines can cause you to wake during the night to urinate. That interruption breaks sleep continuity, lowers sleep efficiency, and can make daytime functioning worse. The other statements don’t fit: diuretics do have an impact on sleep, they don’t generally improve deep sleep or reduce awakenings, and they don’t eliminate sleep apnea symptoms. A practical approach is to take the diuretic earlier in the day and manage fluid intake in the evening, while monitoring for nocturnal awakenings and discussing alternatives with a clinician if needed.
