Question: Do you burn calories when you have a fever?

Fever is part of the immune system’s attempt to beat the bugs. It raises body temperature, which increases metabolism and results in more calories burned; for each degree of temperature rise, the energy demand increases further. So taking in calories becomes important. Even more crucial is drinking.

Does your body need more calories when sick?

Does raising your body temperature burn calories?

Does raising body temperature raise metabolism?

It has been known since early in the 20th century that a rise in temperature is associated with an increase in metabolic rate. Each degree C rise in temperature is associated with a 10–13% increment in oxygen consumption (18). The elevation in temperature itself is responsible for speeding up metabolism.
