Here is a nice visualization of the Circadian rhythm.
Highest testosterone secretion at 9:00 and highest alertness at 10:00.
Overview of biological circadian clock in humans.
Biological clock affects the daily rhythm of many physiological processes. This diagram depicts the circadian patterns typical of someone who rises early in morning, eats lunch around noon, and sleeps at night (10 p.m.). Although circadian rhythms tend to be synchronized with cycles of light and dark, other factors - such as ambient temperature, meal times, napping schedule and duration, stress and exercise - can influence the timing as w
