How does temperature change during the day?

Daily air temperatures at Earth’s surface are controlled by the incoming and outgoing energy. During the day, the air temperature increases as energy gains exceed the energy lost from Earth’s surface. Throughout the night, the air temperature decreases as Earth’s surface loses more energy than it receives.

Body temperature varies throughout the day and is lowest in the morning and highest in the afternoon. Your body has a complex thermoregulation mechanism to help keep its temperature within the normal ranges.
