What Is a Calorie

{{B}} When to Take Medicine Is Important{{/B}}
Our bodies are wonderfully skillful at maintaining balance. When the temperature jumps, we sweat to cool down. When our blood pressure falls, our hearts pound to compensate. As it turns out, though, our natural state is not a steady one. Researchers are finding that everything from blood pressure to brain function varies rhythmically with the cycles of sun, moon and seasons. And their insights are yielding new strategies for keeping away such common killers as heart disease and cancer. Only one doctor in 20 has a good knowledge of the growing field of "chronotherapeutics", the strategic use of time (chronos) in medicine. But according to a new American Medical Association poll, three out of four are eager to change that. "That field is exploding," says Michael Smolensky.

B. People increase or lower the body temperature by sweating.
C. People’s hearts pound to compensate when the blood pressure goes up.
