Quizplus · Accepted Answer

Normal body temperature can vary slightly due to all of the factors listed in the options (exercise, menstrual cycle, time of day, and exposure to extremes in environmental temperature). For example, body temperature usually increases during exercise and in the late afternoon or early evening, and decreases during sleep or in the early morning. The menstrual cycle can also cause temporary increases in body temperature. Finally, exposure to extreme environmental temperatures can affect our body's ability to regulate internal temperature and cause variations in body temperature.
