The part of the body that controls body temperature, sleep, and appetite is the hypothalamus.

Quick Scoop

  • The hypothalamus is a small but vital region located at the base of the brain.
  • It regulates body temperature (acting like an internal thermostat), helps control sleep cycles, and manages hunger and appetite signals.
  • Because it links the nervous system and the endocrine system, the hypothalamus plays a central role in maintaining overall homeostasis (the body’s internal balance).

So, if the question is “Which of the following controls body temperature, sleep, and appetite?”, the correct option is: Hypothalamus.
