Q

How does the circadian rhythm affect our daily functioning?

A

Body temperature rises as dawn nears, peaks during the day, dips in the afternoon then drops again in the evening.

Thinking and memory improve as we approach our daily peak in circadian arousal.

Age and experience may alter our circadian rhythm.
