    As humans fall asleep, body activity slows down. Body temperature, heart rate, breathing rate, and energy use all decrease. Brain waves slow down. The excitatory neurotransmitter acetylcholine becomes less available in the brain. [9] Humans often maneuver to create a thermally friendly environment—for example, by curling up into a ball if cold.
