The kidneys keep your body from losing too much water, sugar, or salt. true or false

False because your kidneys filter out waste you dont need so in other words they act like a filter for your blood stream filtering out any toxins salt or other things the human body doesnt need

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
