Is it normal to pee dark yellow in the morning?
Mostly.Normal for most people
Yes—dark yellow pee first thing in the morning is usually normal because you haven’t had anything to drink overnight. It should generally get lighter as you drink fluids during the day.
Your kidneys keep making urine while you sleep, but you’re not taking in fluids, so the urine gets more concentrated and can look darker. Lots of people notice this in the morning.
