Dehydration happens when your body gets rid of more fluids, usually through sweating or going to the bathroom more than normal, than it absorbs. Drinking too little water during exercise, hot weather, or daily activities can also cause the body to use up its stored water.
Nocturia is defined as the excessive need to get up and urinate during the night. 1  You may find yourself using the bathroom several times per night and this can be disruptive to your sleep. It is generally considered to be abnormal to wake to urinate when it occurs more than once at night.
Every night for two weeks you go to bed at the same time and see what time you wake up by yourself next morning. For the first few nights you might well be catching up on missed sleep, but after that the time you wake up gives an indication of the length of your ideal nightâs sleep. You might be disappointed to find you need more sleep than youâd hoped, but donât see it as a waste.
