How to Lower Your Thermostat Without Freezing This Winter

Hold daytime warmth, drop heat while asleep or out, and seal drafts to stay cozy while spending less.
Lower your thermostat without freezing by holding about 68°F while awake at home, then lowering it while asleep or away. A setback means keeping that lower setting for hours, and the U.S. Department of Energy recommends that pattern in its thermostat guidance.
The U.S. Department of Energy says an 8-hour setback of 7–10°F can save as much as 10% per year on heating (winter energy-saving steps). Use sleep and work hours to cover that long block without much effort.

Why does holding steady beat frequent changes?
Your body notices swings more than a stable cool room. Pick one daytime approach and hold it for several days before judging comfort. Small shifts feel easier when your schedule, clothing, and blankets stay predictable.
Move around during cold spots instead of raising heat right away. Warm socks, layered tops, and a throw on the couch add comfort without touching the dial. Hot drinks and cooking also warm hands and rooms for short spells.
How do you time sleep and away dips?
Link lower heat to times you barely feel the room. Sleep hours and errands or office hours give long unnoticed blocks. Keep doors inside open so remaining warmth spreads evenly.
Make the change automatic so comfort does not depend on memory.
- Set the dip before bed, not at bedtime, so rooms cool gradually.
- Raise heat a little before waking, not to a high blast.
- Use a programmable schedule so evening and morning shifts happen alone.
When should you keep heat higher?
Older adults need extra warmth, even in a mildly cool house. The National Institute on Aging tells older adults to keep heat at least at 68°F because 60–65°F can bring hypothermia (cold-weather safety guidance). Keep guest rooms and visits at that higher level too.
Do not chase savings in rooms used by older relatives. If anyone feels dizzy, shivery, or unusually cold, raise heat and add warm layers right away.
What makes a lower setting feel warmer?
Drafts make a reasonable setting feel cold. The U.S. Department of Energy ties comfort at lower settings to sealed leaks, insulation, fixed ducts, and curtain use in its home energy checklist.
Focus on windows, doors, and attic access first. Open south-facing curtains by day for sun warmth, then close them at night. Add rugs on bare floors and close off unused rooms with doors shut.
Feel for cold air around frames after windy nights and seal what you find.
