  • Your core body temperature drops 1-2 degrees during sleep
  • A cool room helps trigger this natural temperature decline
  • Too warm leads to restlessness and reduced deep sleep
  • Too cold causes the body to work harder to maintain warmth

About Optimal Room Temperature

Find the ideal bedroom temperature for better sleep quality. Science-based recommendations by age. This tool uses evidence-based sleep science to provide accurate recommendations for better rest.

The Science of Sleep Cycles

A complete sleep cycle lasts approximately 90 minutes and consists of four stages: two stages of light sleep, one stage of deep sleep, and REM (Rapid Eye Movement) sleep. Waking up between cycles, rather than in the middle of one, helps you feel more refreshed and alert.
