Thermal Cues for Deeper Sleep

Use temperature timing and bedroom setup cues to help the body transition into deeper sleep.

Thermal cues that support deeper sleep
Thermal cues help the body downshift into sleep mode.

Cool the core before bed

A gentle drop in body temperature signals the nervous system to shift into sleep mode. Use a brief cooling routine to support that transition.

  • Take a warm shower 60 to 90 minutes before sleep.
  • Keep bedroom temperature between 65 and 68 degrees.
  • Use breathable sheets to release excess heat.

Use airflow to stabilize comfort

Consistent air movement helps the body regulate temperature without waking. Small adjustments can improve comfort for longer sleep cycles.

  • Set a low fan speed aimed away from the face.
  • Layer a light blanket for easy temperature changes.
  • Keep a glass of water nearby to avoid disruptions.

Wellness cue

Sleep depth improves when the bedroom stays cool and steady.

"Temperature is a quiet signal that tells the body it is safe to rest."
