How will other body systems be affected if the kidneys begin to shut down? explain your answer

When your kidneys fail harmful wastes and fluids can build up in your body. Blood pressure may rise and you may not be able to make enough red blood cells.

Because without physical activity, the body has extra "energy" if you will, and so when it is time for bed you are not tired, so you end up staying up all night. also there is probably an effect on your internal clock, which messes with your melatonin production which goes hand in hand with your sleep cycle
