The ideal winter thermostat setting for a house at night is between 𝟔𝟎∘ 𝐅 and 𝟔𝟕∘ 𝐅. The U.S. Department of Energy (DOE) recommends dropping your thermostat by 10∘ F to 15∘ F for 8 hours while sleeping, which can significantly lower heating costs.
Key Takeaways. During the winter, the recommended thermostat settings are 20-22°C (68-72°F) during the day and 17-19°C (62-66°F) at night. To maintain a stable indoor temperature in winter, use smart thermostats, insulate your home properly, replace your windows and doors if they're old, and maintain your HVAC system.
Whether 65°F is considered "cold" for a house at night depends largely on your personal comfort, but health and sleep experts actually consider it an ideal, energy-efficient temperature for sleeping.
Yes, 72°F is widely considered a comfortable and good daytime temperature for your home in winter. It provides a warm, cozy environment while you are active and moving around the house.
For a healthy adult, 62°F (16.7°C) is generally safe, though it can feel uncomfortably chilly. While it is an excellent way to save on heating bills, experts recommend keeping your home above 64°F to 65°F to prevent potential health risks and structural issues.
Maintain your thermostat at a minimum of 55°F (13°C) to protect your pipes. While water freezes at 32∘F (0∘C), keeping the ambient air at 55∘F ensures the temperature within your walls and near exterior-facing pipes stays safely above freezing.
No, 62°F (16.7°C) is not too cold; in fact, it falls perfectly within the optimal temperature range of 60°F to 67°F recommended by sleep experts. This cool environment helps your core body temperature drop, which signals your brain to release melatonin and fall into a deeper sleep.
A house set to 72∘F72 raised to the composed with power F72∘F can still feel uncomfortably cold due to low humidity, drafts, cold surfaces radiating heat away from your body, or the location of your thermostat. Air temperature is only one piece of the puzzle.
It's better to leave interior doors open when heating your home. Open doors allow warm air to circulate evenly, preventing hot and cold spots and reducing the strain on your HVAC system. Closed doors can block airflow, making your system work harder and increasing energy costs.
For October, the ideal thermostat setting is 68∘F68 raised to the composed with power F𝟔𝟖∘𝐅 to 70∘F70 raised to the composed with power F𝟕𝟎∘𝐅 (20∘C20 raised to the composed with power C𝟐𝟎∘𝐂 to 21∘C21 raised to the composed with power C𝟐𝟏∘𝐂) while you are home and awake. For maximum energy efficiency and better sleep, drop the temperature to 60∘F60 raised to the composed with power F𝟔𝟎∘𝐅 to 65∘F65 raised to the composed with power F𝟔𝟓∘𝐅 (15∘C15 raised to the composed with power C𝟏𝟓∘𝐂 to 18∘C18 raised to the composed with power C𝟏𝟖∘𝐂) at night or when away.
If your home isn't well-insulated, it loses heat fast. At night, the outdoor temperature typically drops, and if your walls, roof, floors, or windows are not properly insulated, the warmth inside your home will naturally escape — and cold air can sneak in.
The ideal room temperature for sleep is anywhere from 60°F to 65°F (15.6°C to 18.3°C.) However, everyone is different, and this temperature may not work for you. Infants and older adults may also need a slightly warmer room temperature. Your body's temperature decreases before sleep.
Cold homes are not good for your health. Problems and diseases linked to cold homes range from high blood pressure and common colds, to heart attacks and pneumonia. Besides poor health, cold-related illnesses cause absence from work, social isolation, and sleep deprivation.
10 Home Heating Tips To Keep Your Home Warm
Experts recommend setting your thermostat between 60°F and 67°F (15.5°C to 19.5°C) at night for optimal sleep. This cool range supports your body's natural drop in core temperature, which helps you fall asleep faster and prevents you from waking up throughout the night.
A cooler bedroom supports deep sleep by aligning with the body's natural temperature drop. Ideal sleep temperatures range from 60°F to 67°F (15°C to 19°C) for optimal rest. Overheating at night can reduce deep sleep and increase wakefulness.
Because warm air naturally rises, the roof and attic account for the largest percentage of heat loss in a typical home, responsible for about 25% of escaping warmth.
Whether a room gets colder with the door open or closed depends entirely on your cooling source. It is highly dependent on whether you are using a central HVAC system, a localized unit (like a window AC), or relying on outside air.
The cheapest way to heat a house with electricity or gas could be to use a programmable thermostat that works with your heating system. Many programmable thermostats allow you to manually set different temperatures for different times of the day, such as lowering the temperature at night.
To quickly block cold air and drafts, seal gaps around baseboards and outlets with Great Stuff Insulating Foam. For larger wall surfaces, you can hang thick insulated thermal curtains, apply reflective radiant barriers like Reflectix Rolls, or install rigid foam boards.
You typically start noticing an increased sensitivity to cold between your 50s and 70s, as natural age-related changes—like a slower metabolism, loss of muscle mass, and thinning of the insulating fat layer under your skin—reduce your body's ability to generate and retain heat.
No, it is generally not cheaper to leave your heating on low all day. According to the U.S. Department of Energy, maintaining a constant temperature results in continuous heat loss, causing your system to consume more overall energy.
Japanese people typically sleep in rooms that average around 55°F (13∘𝐶) in the winter, and 25∘𝐶 to 28∘𝐶 in the summer. Rather than heating or cooling the entire house, locals rely on targeted air conditioning, layers, and breathable bedding to maintain optimal core body temperature.
The 10-3-2-1-0 sleep rule is a popular routine designed to improve your sleep hygiene. It provides specific timeframes for cutting out everyday stimulants and habits to ensure your brain and body can naturally transition into a deep, restful state.
It is generally better to sleep in a cold room. Experts recommend keeping the bedroom thermostat between 60∘F60 raised to the composed with power F𝟔𝟎∘𝐅 and 67∘F67 raised to the composed with power F𝟔𝟕∘𝐅 (15.6∘C15.6 raised to the composed with power C15.6∘C to 19.4∘C19.4 raised to the composed with power C19.4∘C).
