Answer :
Final answer:
The body is most susceptible to sleep late in the evening and during the early morning hours due to the circadian rhythm. This rhythm influences body temperature, attention levels, and behaviors, impacting sleep patterns. Understanding one's circadian rhythm can help optimize productivity.
Explanation:
Circadian rhythm plays a significant role in determining the body's susceptibility to sleep at different times of the day. Body temperature, attention levels, and other behaviors follow a natural rhythm, with the body being most susceptible to sleep late in the evening and during the early morning hours.
For example, a chart showing the circadian change in body temperature over 28 hours depicts that body temperature rises throughout the waking day, peaks in the afternoon, and falls during sleep, reaching the lowest point in the very early morning hours.
Understanding one's circadian rhythm can help individuals optimize their productivity by determining the best time for studying or working based on their internal biological clock.
