Winter Months Alternate forms of heat can help you lower that temperature for an additional cost and energy savings. Nighttime: “Lower the thermostat setting by a few degrees during the night, ideally around 62°F-65°F,” suggests Roberson.
Your thermostat should be set to around 18-21°C, which is the lowest comfortable temperature that is economical too. Not only will this lower your heating bills, it will help to lower your carbon footprint and reduce your households' environmental impact.
How Hot Is Too Hot? Different sources disagree on a maximum indoor temperature setting in winter. However, 72 degrees is the average recommendation. Setting the thermostat higher than the low 70s inevitably increases heat loss to the outdoors, raising heating bills substantially.
When it comes to the best temperature for your furnace in the winter at night, it is time to turn that thermostat down. As a general rule, the recommended heater temperature at night is between 60 and 67 degrees Fahrenheit. A thermostat setting of around 65 degrees is actually better for your health.
So, if you and everyone else in the household are comfortable with going lower than 64 degrees while sleeping, then go for it! As far as the normal hours of the day when everyone is awake and active in the home, we do recommend the WHO's guideline of 64 degrees (F) as a minimum.
The best room temperature for sleep is approximately 65 degrees Fahrenheit (18.3 degrees Celsius). This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 65 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep.
A better idea: Turn the heat down, not off
Here's the secret: Set the temperature of your home at least eight degrees lower for the eight hours or so that you sleep at night. Every degree you lower the thermostat can net you an estimated 1% off your heating bill.
What is the Healthiest Temperature to Keep in Your House? The sweet spot for indoor temperature is typically around 20-22 degrees Celsius (68-72 degrees Fahrenheit). This range promotes better sleep, aids concentration, and supports overall physical comfort. Straying too far from this range may lead to health issues.
The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees Fahrenheit for healthy people. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems. Watch out for signs of hypothermia.
“Anything under 68 degrees overall is ideal for sleep. If you get too hot in the middle of the night, reduce layers of clothing or sheets, turn on fans, or drink a little cold water.”
There may be drafts and pockets of colder air near the floor; The walls are colder and don't emit the usual amount of infrared radiation, so you lose heat due to your body emitting more IR than it receives; You may spend more time indoors and hence have less physical activity, so your body generates less heat.
The best winter thermostat setting is 62 to 68 degrees. On winter days, program your home's thermostat to 68 degrees for a comfortable indoor temperature while you're home and awake. When sleeping, program your thermostat to 62 degrees. Consider rolling this temperature back to 55 degrees when no one is home.
turn down the thermostat to between 18 and 21˚C – every degree warmer costs you around 5–10% more. turn your heater off overnight or turn the thermostat down even further.
To save money, aim to have your temperature set around 68-72 degrees Fahrenheit when you're at home and awake. This is a comfortable temperature for most with the help of a light sweater. Overnight and when you're out, around 64 degrees Fahrenheit will keep your home at a good temperature.
Heat the home: Heat your home to at least 18°C (65°F), if you can, you might prefer your living room to be slightly warmer. Remember to keep your window closed on winter nights as breathing in cold air can be bad for your health because it increases the risk of chest infections.
68 to 72 degrees is a temperature range that is not too warm or cool, and is sufficient enough to warm up the home just enough so that everyone is comfortable regardless of the type of clothing they have on.
Nighttime: “Lower the thermostat setting by a few degrees during the night, ideally around 62°F-65°F,” suggests Roberson. To ensure you're nice and toasty, call on extra blankets and warm PJs before you kick up the thermostat.
Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you're asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
The U.S. Department of Energy says an indoor temperature of 65 degrees Fahrenheit at night is best.
The Energy Saving Trust states the thermostat in your home should be set to the lowest comfortable temperature (usually between 18C and 21C), while an official report also outlines 18C as the recommended minimum. The vulnerable may wish to heat it slightly higher, and healthy people may wish to heat it slightly less.
So, in the sense of completely shutting off your heat and cranking it back up, it will cost you more. There are also health risks associated with setting your thermostat at a too-low temperature during winter, especially for seniors.
“Looking at the available research, most studies agree that a temperature between 60 and 67 degrees Fahrenheit is optimal for sleeping, with temperatures above 75 degrees and below 54 degrees disruptive to sleep.
The best way to prevent a fire is to never leave a space heater running in a room unattended—that way, if anything does go wrong, you can take action quickly. If you have kids or pets that could knock a heater over or drape fabric on it, keep a very close eye on its operation.
But when you're trying to sleep, you might prefer to set the thermostat a little lower. Your core body temperature should drop by a few degrees in order for you to reach a state of deep sleep. So a cooler room — around 16–18°C — can help you reach this optimal temperature.
