The normal rectal temperature at rest is about________- the oral temperature.

Individuals who are sodium-sensitive experience an increase in blood pressure, possibly because of a defect in sodium excretion by the kidney. Sodium accumulates in the body and holds fluids, particularly in the blood, thereby raising blood pressure.

Glycerol supplementation is considered safe for diabetic athletes.

During exercise, approximately what percent of the energy produced is released as heat in the body?

After exercise, as compared to oral temperature recording, a rectal reading may be a more accurate reflection of the true body temperature in an assessment of stored body heat.
