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 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.
64 degrees is the minimum it should be and that still has complication. Anything lower can cause health concerns. If your parents in law are elderly you're putting them at risk. And I'm on their side at 70. For reference in my city landlords have to keep their homes/apartments at a minimum of 68 degrees.
It's advisable to keep your home below 80 degrees throughout the summer. A house that's too warm can be dangerous to people, pets, and the soft surfaces in your home. Set the winter temperature to 68 degrees when you're awake and 62 degrees when you're sleeping.
The World Health Organization recommends a thermostat setting no lower than 68 degrees while you're home. If you have children or seniors in your house, that number increases to at least 70 degrees. If your house is too cold, it can cause problems with blood pressure and circulation, as well as affect your heart rate.
Sleeping too hot
“Heat is a huge disruptor for REM sleep,” Dr. Drerup says. With the heat of the room, your body temperature will also rise, thus undoing the sleep initiation process entirely. If your bedroom temperature is above 70° F, it's too hot.
The ideal temperature would be around 55 to 60 degrees. This will be warm enough to keep pipes from freezing. This might seem too much for some homeowners due to the added costs in their expenses. However, a higher utility bill will still be cheaper compared to what you will spend if your pipes freeze and burst.
Recommended Temperature When the Home is Vacant
For short periods of time away, like going to work, we'd recommend a temperature of around 55 – 60 degrees (F). While away on long periods of time, such as vacation, we don't recommend setting the temperature any lower than 50 degrees (F).
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.
Keep your house heated to a minimum of 65 degrees.
A temperature lower than 65 degrees might not keep the inside walls from freezing.
How cold can a house get without heat overnight? The time of day your heater goes out impacts how long the house stays warm. Indoor temperatures go down faster at night, so if your furnace stops overnight, you can expect a quicker decline. This can be as much as 15 degrees Fahrenheit before morning.
There are fewer cons to sleeping in a cold bedroom than a warm one, but without the right blankets and clothing, a too-cold room can keep you up all night shivering. Invest in the right pair of pajamas, a thick blanket or warm socks if you know you are prone to getting the chills at night.
Don't set your thermostat too low
"What you want to do is keep it at a reasonable temperature that's not chilly.” The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees for healthy people.
The Ideal Temperature for Sleep
For the best possible sleep environment, keep your bedroom between 60 and 72 degrees Fahrenheit (65 degrees is typically ideal).
Most people sleep best at a cool temperature, around 65 degrees Fahrenheit. But there is some variation depending on the person. Some people sleep better warmer, at about 72 degrees, while others do the best sleeping quite cold, at around 55 degrees.
In general, it's recommended to set your thermostat to 55 degrees Fahrenheit or higher. This may seem high compared to the freezing point of 32 degrees Fahrenheit, but it'll help keep the interior of the floor and wall cavities – where your plumbing is often located – safely above freezing temperatures.
Cold homes contribute to excess winter mortality and morbidity. Most of the health burden can be attributed to both respiratory and cardiovascular disease, especially for older people. In children, the excess winter health burden is mostly due to respiratory disease.
Your pipes are at risk of freezing any time temperatures drop below 32°F. However, it's much more common for pipes to freeze when temperatures dip below 20°F. The longer the weather remains below freezing, the more likely it is your pipes can freeze if not properly protected and winterized.
We all know that freezing begins at 32° F or 0° C, but at what point do pipes freeze within our own homes? Temperatures only need to drop to about 20° F for a few hours to put exposed pipes at risk. So, your best bet is to insulate your exposed pipes to keep that temperature well above the freezing point.
When the temperature drops below 32 degrees F, water in your pipes can freeze and burst. To safeguard your pipes against bursting during periods of frigid temperatures, you can use a couple of simple precautions to protect your pipes. You can wrap exposed pipes in insulating material to keep them from freezing.
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.
Some research suggests that sleeping naked can promote better sleep, leading to various mental and physical health benefits. By encouraging core body temperature regulation, naked sleeping may help support reproductive function, skin health, cortisol levels, metabolic control, and more.
