Optimal Sleep Temperature and The Role of Thermoregulation

The optimal temperature for a good night of sleeping ranges by body size and other factors. Adults typically need the environment to be roughly 60–65 degrees. Children require the room to be 65–70 degrees.


Natural body temperature also changes throughout the night, with the lowest body temperature occurring early in the morning, around 5am. A lot of other factors also influence sleep temperature, including breathable clothes and bedding, air circulation, being hydrated, workout schedule, and shower heat.
