Brief Answer:
The bigger temperature difference!

Detailed Answer:
Hello,

When we are sick, the basal body temperature is raised. How much could we feel really depends on the difference between our core temperature and the temperature of our surroundings.

When we are sick, the difference is bigger and that is why we are more sensitive to lower temperatures than others. Also, the body normally generates heat to compensate for low temperatures. When sick, this process is already strained because the body has already raised the temperature to fight the infection.

Hope I have answered your query.

Brief Answer:
The brain, specifically the hypothalamus!

Detailed Answer:
Hi,

The hypothalamus is the central command/thermostat for temperature control. During a fever, the set point is set higher. As such, the body temperature is higher than usual. Elevated levels of prostaglandin E2 (PGE2) in the hypothalamus appear to be the trigger for raising the set-point.
