  It will just get more concentrated (more of the toxins etc) and will become quite dark in colour and quite smelly!

  Just to add, it’s a brilliant part of keeping our body with enough water in it, if we don’t have much spare water, we don’t use it to dilute the toxins as much as we normally would do. Not a good thing in the long run but it does mean that our bodies can keep relatively stable in terms of what it’s got inside of it!
