4. Feed a cold, starve a fever.
This old saying is linked to the belief that eating will help your body generate warmth, and fasting will help cool it down. According to medics, however, the saying has it a bit wrong.
The correct part is that your body needs energy to fight an illness, and food generates that energy. But this concerns both colds and fevers. When your immune system is fighting a bug and your temperature goes up, so does the energy demand. Simply put, fever burns calories that need to be replenished. So, feed a cold and feed a fever, and don’t forget to drink a lot of liquids!
