During REM sleep, which statement describes body temperature regulation?

Explanation:
During REM sleep, the body's temperature control systems are largely diminished. The hypothalamus and brainstem reduce active thermoregulation, so core temperature tends to drift toward the surrounding environment rather than being tightly maintained. With the body's muscles in atonia, shivering cannot occur, and autonomic responses like sweating are not reliably engaged to adjust temperature. This makes the description that body temperature is not regulated and there is no shivering or sweating the most accurate characterization of REM physiology. The other statements imply active, frequent temperature responses or strict regulation that aren’t typical of REM sleep.
