Fever is a state in which the body intensifies its metabolic processes, demanding significant energy expenditure. This is essential in cases of infection or other illnesses requiring immune system activation. To aid the body in recovery, nutrition must be tailored to its current requirements.
Fever? What is it?
Fever is a state of elevated body temperature above 38°C. It is caused by compounds called pyrogens produced by pathogens. Fever has a positive effect on the body by increasing the body's ability to fight infection. The thermoregulatory center in the brain records the temperature flowing through this area of blood and, depending on the needs, stimulates the mechanisms that increase or decrease body temperature.
Diet in the heat is the rule
Therefore, the changes in diet during a fever are due to the effects of an increase in body temperature. The diet should be improved individually. Increased body temperature by only one degree Celsius causes a 20% increase in metabolism (reduction in glycogen and fat), increased heart rate, 500 ml increase in daily unseen evaporation, increased calorie breakdown. However, the diet should play an important role depending on the factors that cause the fever.
