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.
