Dehydration can cause a loss of strength and stamina and make you feel faint, among many other things.

There are a few things that can increase the risk of dehydration; therefore, drinking plenty of water is necessary when you are exposed to hot environments or when you are in the sun, or when you work out too hard that you sweat profusely, or when you have diabetes, diarrhea, fever or vomiting.

Drinking too much alcohol can also cause so much dehydration. The universal advice when one is hungover is to drink water, excessive water at that. Drinking alcohol is advised to be avoided on an empty stomach because it can potentially increase the risk of dehydration.

Sleep deprivation doesn’t just affect the mental and emotional state; it can potentially hurt the kidneys. When we sleep, the whole body slows down, taking a rest. So when the body is supposed to rest, forcing it to function like it normally does when it is awake is overworking it. Any machine that is forced to overwork always ends up being damaged.

The body is designed to decrease its workload when it goes to bed, but drinking water before bed basically overrules that by putting pressure to function normally. This can harm the smooth function of kidneys in the long run.

Consuming a glass of water an hour or two before bed would do the trick for the most part, but even if then nocturia doesn’t reduce or go away, then here are few things you should reduce or avoid before you go to bed: soda, coffee, cocoa, tea, and alcohol.

Caffeine and alcohol can cause an increase in the need to urinate, so trying to avoid them will help get a peaceful sleep.
