Night urination and sleep disorders?

Nighttime urination, also known as nocturia, can indeed be a sign of sleep disorders. According to Andrew Huberman, if you are waking up multiple times a night to urinate (more than once), it might indicate a sleep disorder. This is particularly the case if your vasopressin levels drop during sleep disruptions, leading to increased kidney activity and urine production. Normally, vasopressin helps to reduce urine production during the night 1.

To manage nocturia and improve sleep, Dr. Huberman recommends ensuring adequate hydration during the day and minimizing fluid intake in the evening. Specifically, he suggests consuming no more than 5-8 ounces of fluid in the last few hours before sleep, and ideally sipping rather than gulping to slow down fluid absorption 2. This approach helps in reducing the frequency of nighttime urination and may contribute to better sleep quality.
