What effect does exercise have on the nervous system? a. prolonged exercise degenerates the nervous system. b. increased blood flow reduces nerve sensitivity. c. repetitive motion develops nerves and nerve endings. d. higher body temperature impairs nerve message transm

The answer is C. Repetitive motion develops nerves and nerve endings. Nerves have neurons, neurons have receptors. When we exercise, the neurons in the nerves gets activated and opens up the receptors which in turn helps in developing the nerves. For example. if you have a serious muscle cramp the nerve gets affected by it and gets weaker. Then when you do physiotherapy regularly it slowly gets cured as it unblocks the nerve and develops it.

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
