Quick answer: The ideal house temperature is room temperature, which ranges from 68 to 78 degrees F, though this may vary from season to season. In winter, the average room temperature is generally 62 to 68 degrees, whereas in the summer, the average temperature is 72 to 78 degrees.
In the winter, experts recommend that you set your thermostat to 68 degrees Fahrenheit when you're home, and 60 to 65 degrees when you're asleep or away. You can set it higher, but that will reduce efficiency and lead to higher energy bills.
Excessive Heating
Avoid setting the thermostat in your house above 72 degrees in the winter. Adjusting your thermostat to this temperature wastes energy and increases your energy bill significantly. Overheating your space also decreases humidity levels in your home, which creates a dry environment.
A common temperature to keep your home at during the winter is 68 degrees Fahrenheit. However, you can also keep it between 70 and 78 degrees, depending on your home type and what you're personally comfortable with.
As you know, not all people feel comfortable at the same temperature and relative humidity, but to answer your question, most people feel comfortable with a set point temperature on the thermostat at 73--75 F during summer and 68--70 F during winter.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
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.

For most people, 75 degrees is too hot to sleep, per the National Sleep Foundation. But the new study found that in people 65 and up, sleep efficiency only started to decrease when temperatures were above 77 degrees.
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.
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home. If there are infants or elderly individuals, they recommend keeping the temperature at 70 degrees at a minimum.
You can easily save energy in the winter by setting the thermostat to around 68°F to 70°F while you're awake and setting it lower while you're asleep or away from home.
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.
The U.S. government Department of Energy (DOE) states that people should set their thermostats to 68 degrees F. This is the optimal temperature for keeping a home comfortable.
U.S. Department of Energy research suggests that setting your programmable thermostat to 78 during the summer months is the best way to save money on your cooling costs while maintaining a comfortable temperature.
The recommended rule of thumb for summertime is to set the temperature to 78 degrees Fahrenheit when you're home and higher when you're away. In general, set it to 82 degrees Fahrenheit when you're asleep and 85 degrees Fahrenheit when you're away.
Most sleep specialists recommend people sleep in a “cool, dark and quiet environment,” typically ranging from about 65 to 75 degrees, said Ronald Chervin, the division chief of the sleep disorders centers and professor of sleep medicine at the University of Michigan, who was not involved in the study.
In general, summertime thermostat settings should be set between 73-78 degrees Fahrenheit, while winter temperature settings should range between 68-72 degrees Fahrenheit.
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.
For many of us, 70 degrees is the ideal indoor temperature, but when it is close to 100 degrees outside, your AC unit will be working quite hard to meet these expectations. Consider setting your thermostat at 75 degrees to 80 degrees in your home if the outside temperature is approaching triple digits.
If your ductwork is leaking or damaged, it can draw hot air back into the supply ducts or let all of the cooled air escape. This can result in the AC system blowing hot air through the house. Ductwork leaks can also reduce the volume of air flowing through the system.
A typical thermostat setting is between 68° and 76°. Where you choose to set your thermostat might depend on the season as well as your own personal preferences.
If your comfort is most important to you, then absolutely set your thermostat to a comfortable temperature (usually between 70-74), and leave it there while you are home and awake.
An influential limit. After an influential study in 2010, climate researchers often use a wet bulb temperature of 35 degrees C — roughly equivalent to 95 degrees F at 100% humidity — as an upper limit for human survival and adaptability without cooling.
"The mucous membranes can dry out, crack a little, allowing viruses to seed and produce disease," said physician assistant Lou Melini. That is what can happen in a hot home. "To crank it up to 86 degrees, I think that's a bit excessive. It's drying and counterproductive," Melini said.
