We are still losing water though: through the skin as sweat, through moisture when we breathe, and through the making of urine in the kidneys[2]. This means that we net lose water while we sleep, so we get dehydrated at night.

Dehydration can lead to fatigue , which could lend some explanation as to why you always feel so tired when you wake up! This tells your kidneys to absorb more water back into the body, rather than making urine[7]. It also makes you feel thirsty to get you to drink more water[2].

At night, we release more ADH from the brain as a natural way to stop us getting dehydrated during the night. As we get older though, the daily rhythm of the part of the brain that releases the ADH is thought to decrease, which may be why as we age we tend to need to get up to visit the bathroom more often[8].

This was highlighted by a recent study that showed that peeing more at night and disturbed sleep happens to people who lack that increased release of ADH at night[7]. When we breathe in, the air is heated and humidified as it moves into the lungs. When we breath back out, some of this heat and water is lost[3]. Studies show that factors such as lighting, light from your phone and noise affect your sleeping environment.

However temperature also plays a part. During further experiments in the mice, the scientists found that the vasopressin hormone indeed activated the brain cells associated with thirst, according to the study, published today Sept. However, more research is needed to see if the same mechanisms are at work in humans, Bourque told Live Science.

Still, the new findings may help researchers to better understand how the brain's inner clock works, the researchers said. Originally published on Live Science.
