What's the Ideal Home Temperature? See How You Compare

Have you ever wondered if your hand on the thermostat makes your home an icebox or a sauna compared to everyone else? It’s a common question. Finding that perfect temperature is a balance between personal comfort, health, and energy savings. This guide will explore the recommended temperatures so you can see exactly how you stack up.

The "Average" Thermostat Setting Most People Use

The question in the ad is simple: are you warmer or cooler than most people? To answer that, we need a baseline. While personal preference varies, several organizations have established guidelines based on energy efficiency and general comfort.

According to the U.S. Department of Energy, the most cost-effective and generally comfortable settings are:

Winter Months: The recommended temperature is 68°F (20°C) when you are awake and at home.
Summer Months: The recommended temperature is 78°F (25.5°C) when you are at home.

These numbers represent a sweet spot. They are designed to keep most people comfortable without sending energy bills through the roof. If you keep your thermostat set significantly higher in the winter or lower in the summer, you likely prefer a temperature that is warmer or cooler than the average, energy-conscious household.

Why Your Personal Preference Might Be Different

Of course, “average” doesn’t mean “right” for everyone. Numerous factors can influence why you might prefer a warmer or cooler environment. Your ideal temperature isn’t just a random choice; it’s often influenced by your biology, health, and even your home’s characteristics.

Key Factors Influencing Thermal Comfort:

Age: Body temperature regulation changes as we age. Infants and elderly individuals often have more difficulty regulating their body heat and typically require a warmer environment to stay comfortable and safe.
Metabolism: People with faster metabolisms generate more body heat and may feel more comfortable in cooler rooms. Conversely, those with slower metabolisms might feel a constant chill and prefer a warmer setting.
Health Conditions: Certain medical conditions, such as thyroid issues or anemia, can make a person feel perpetually cold. Other conditions can cause hot flashes, leading to a preference for a cooler home.
Activity Level: If you work from home and are mostly sedentary, you might prefer a warmer temperature than someone who is constantly moving around the house doing chores or exercising.
Humidity: The amount of moisture in the air plays a huge role. High humidity can make a 75°F day feel sticky and much hotter, while very dry air can make the same temperature feel cooler.

The Best Temperature for a Good Night's Sleep

Where the science gets particularly interesting is the temperature of your bedroom at night. While you might crank up the heat to feel cozy in the living room, experts suggest doing the opposite when you go to bed.

Sleep researchers and institutions like the Sleep Foundation recommend a bedroom temperature between 60 and 67°F (15.6 to 19.4°C) for optimal sleep. Your body’s core temperature naturally drops as you prepare for sleep, and a cool room helps facilitate this process. Sleeping in a room that is too warm can interfere with your sleep cycle, particularly the REM and deep sleep stages, leaving you feeling tired the next day. So, if you’re sleeping in a cool room, you’re not just saving on energy bills; you’re likely getting better rest.

How to Optimize Your Home's Temperature for Comfort and Savings

Whether you run hot or cold, you can manage your home’s climate more effectively. This allows you to stay comfortable while also keeping your energy consumption in check.

Embrace Smart Technology

A programmable or smart thermostat is one of the best investments for any home. Models from brands like Google Nest, Ecobee, or Honeywell allow you to create a schedule that automatically adjusts the temperature.

Set it cooler when you’re sleeping or away from home.
Program it to warm up or cool down just before you wake up or arrive home.
The Department of Energy estimates you can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting.

Seal Air Leaks

Your home could be losing a significant amount of heated or cooled air through small cracks and gaps. Check for leaks around windows, doors, and electrical outlets. Use weatherstripping for moving components like doors and windows, and apply caulk for stationary cracks and gaps. This simple and inexpensive fix can make a big difference in maintaining a consistent temperature.

Use Your Ceiling Fans Correctly

Ceiling fans are not just for summer. In fact, they can help in the winter, too. Most fans have a switch that reverses the blade direction.

In the Summer: Set the blades to rotate counter-clockwise. This pushes cool air down, creating a wind-chill effect that makes you feel cooler.
In the Winter: Set the blades to rotate clockwise on a low speed. This pulls cool air up and pushes the warm air that has risen to the ceiling back down into the living space.

Manage Your Windows

Your windows are a major source of heat gain in the summer and heat loss in the winter. Use them to your advantage.

During sunny winter days, open your curtains to let the sunlight in and naturally warm your home.
During hot summer days, close your curtains or blinds, especially on south-facing windows, to block out solar heat and reduce the load on your air conditioner.

By understanding the recommended averages and the factors that influence your personal comfort, you can make informed decisions about your thermostat. You can find the perfect balance that keeps you comfortable, your family happy, and your energy bills manageable.
