Which relationship between circadian rhythm and body temperature is accurate for a person who sleeps at night and is awake during the day?

Answer 1

For a person who sleeps at night and is awake during the day, body temperature typically follows a circadian rhythm that correlates with their sleep-wake cycle. Body temperature generally decreases during the night, reaching its lowest point in the early morning, which aligns with sleep. As morning progresses and the person wakes up, body temperature gradually rises, peaking in the late afternoon or early evening. This fluctuation helps promote alertness during the day and facilitates sleep at night.
