Why does dehydration happen?
Dehydration happens for lots of reasons. You’re often dehydrated in the morning when you wake up simply from sleeping for hours (hopefully lots of them!) without fluids. The processes in your body are working hard while you sleep, and even just breathing results in water loss from your body. But the most common causes of dehydration are simply not drinking enough regularly and not drinking enough during or after activity to replace what’s been lost. Most of the time people don’t recognize the signs of dehydration and only drink when they feel thirsty. By the time you feel thirsty you are already dehydrated and are probably being affected in more ways than you realize.
