In general, temperatures _____________________ throughout the night.

During the night, it is typical for body temperatures to drop. This decrease in temperature is a natural part of the body's circadian rhythm, which regulates various physiological processes over a 24-hour cycle. As the evening progresses into night, metabolic processes slow down, and the body transitions into a state that promotes rest and repair.

The gradual decline in temperature helps signal the body that it is time for sleep. Cooler ambient temperatures at night also encourage this drop as they facilitate the body's ability to cool down for optimal sleep conditions. In contrast, body temperatures usually rise during the day when activity levels are higher and the body requires more energy and alertness.

While it is true that temperatures can reach dangerously low levels due to extreme conditions or health issues, this is not a general phenomenon experienced every night. The consistent pattern of a temperature drop is a key factor in understanding how the body regulates itself during different times of day.
