Question

Why humans can adjust to fluctuation of temperature form morning to evening?

Answer 1

Is your body temperature 98.6 degrees and falling? If so, it can reveal a lot about your health. In fact, body temperature is one of four vital signs doctors watch for, the other three being blood pressure, pulse rate, and respiration rate.

As you probably know, 98.6 degrees F is considered a normal body temperature, though healthy adults can range between 97.8 degrees F and 99 degrees F. Our bodies also constantly adapt their temperature according to environmental conditions. Body temperature rises when you exercise. You may have low body temperature at night. And if you check your body temperature with a thermometer, you will see that it’s higher in the afternoon than first thing in the morning when you rise.
