It’s probably happened to you more than once: you go to bed tired, hoping to sleep through the night, but around 2 a.m., you open your eyes and can’t get back to sleep. The first reaction is usually to blame the glass of water you drank before bed, but the truth is much more complex.
According to sleep experts, the bladder isn’t always the main culprit. It’s actually an imbalance in how the body regulates fluids and temperature during the night.
During the day, gravity causes fluid to accumulate in the feet and ankles. When lying down, this excess fluid is redistributed into the bloodstream, putting more strain on the kidneys and creating the urge to urinate.See more

Furthermore, changes in body temperature can disrupt deep sleep by making you more sensitive to internal signals, even when your bladder isn’t completely full.
Finally, stress and hormonal fluctuations in the early morning activate the nervous system and wake you up for no apparent reason.
The role of sleeping position
Sleeping position is very important. Lying on your back facilitates the redistribution of fluids towards the center of the body, which stimulates kidney function. Sleeping on your side, especially your left, relieves pressure on the bladder and improves blood circulation.
