Stop blaming the water: the real reason you wake up at 2 a.m. is completely different.

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.

 

In addition, changes in body temperature can disrupt deep sleep by making you more sensitive to internal signals, even when your bladder is not 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 side, relieves pressure on the bladder and improves blood circulation.

The influence of temperature and microclimate in the room

A room that is too hot or too cold can disrupt deep sleep phases.

 

In case of heat: the body is unable to lower its internal temperature and remains in a light sleep.

In cold weather: “cold diuresis” is activated, during which the kidneys begin to produce more urine.
