In a healthy person, below normal hydration levels, the body produces an average of 1-2 liters of urine per day. Most of the urine production occurs during waking hours, and only 20-30% of urine is produced during sleep. Different factors have been hypothesized to affect urine production or voiding physiology. It may be due to internal and external factors such as age, antidiuretic hormone, fluid consumption, and caffeine intake, that affect urine production. In the literature, there is no study that investigates the impact of movement, physical activity and position on urine production.
