Body Temperature while Sleeping
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.
