Acute Sleep Deprivation Leads To Changes In Nighttime Urine ProductionReleased August 8, 2007
- Our body’s production of urine follows a circadian rhythm. During the day, we experience greater urinary frequency; at night, urine production declines, enabling us to get uninterrupted sleep. The regulation of urine excretion during nighttime hours is influenced by many factors, including hormones, blood flow, and sleep-related factors. The mechanism behind the day/night changes is not yet clear. Danish researchers who have examined the urinary patterns of sleep-deprived volunteers have found that a lack of sleep leads to increased urinary output and more salt in the urine. The findings were found to be more prevalent in males than females.
