Answer 1

it helps conserve energy to put toward other things, such as making antibodies.

you have a temperature and this extra heat produced zaps your energy

also all your energy is used to fight infection

Answer 3

Your system needs time to heal itself - it is done during sleep. As they say, sleep is the best medicine...

B/c your body is putting a whole lot of energy into fighting off the infection and so other functions become less active... hence you don't feel like eating or really doing much of anything.

Answer 5

becuase your body knows how to take care of itself and in this case rest is the key

Sleep allows your body stuff to fight the ilness.
