You most likely do not drink enough water (coffee etc doesn't count). For the next couple of days make sure to drink around 1.5l of water (it's really hard to drink more if you do not have the habit) and not at once, separate it through out the day and see if there are improvements. If yes - you are most likely fine, if not - see a doctor.
It's not normal. There are two reasons, probably inter-related.
1. You are not drinking enough water.
This leads to the second reason, that is
2. Your body temperature is irregular. Your body temperature is increasing as you're not drinking enough water.
The one thing you can do is drink however much water you can, set a target of how much you wanna drink in an hour and try to complete the target.
Try to have juices and smoothies as snacks instead of junk food.
Hope this helps :)
Is it normal for your pee to be dark? (Mine is dark orange almost brown...)
