Cold is a relative term for less heat Heat can only travel from a higher temperature to a lower temperature If your body is at an elevated temperature, more heat travels away from your body than you are used to, so you feel cold.
Your temperature rises because your body is fighting off an infectionYou feel cold because you sweat, and the temperature outside of your body is cooler than your body temperatureYou drink fluids to stay hydrated, typically people become dehydrated faster while they have a feverThe reason people drink hot fluids is more or less a matter of personal preference.
When you develop a fever, the body sends signals to the hypothalamus that tells it to raise the setpoint to a higher temperatureOften, but not always, this is a response to an infection, such as a bacterium or a virusThe immune cells that respond to the infection secrete molecules called endogenous pyrogens(Endogenous means made by the body, and a pyrogen is something that causes the temperature to rise.) The endogenous pyrogens travel through the blood and reach the hypothalamus, where they cause the setpoint to increaseOnce that happens, the hypothalamus tells the body, You're too coldRemember that the temperature may be normal in this situation, but what matters is that the temperature is lower than the setpoint, which has been raisedSo you feel cold, get under the blankets, and shiver.
Your body is trying to raise the temperature of your body, the heat from hot drinks help do so.
