Best Indoor Temperature Settings for Optimal Home Comfort

Maintaining the perfect indoor temperature is essential for optimal home comfort. A temperature range of 68°F to 72°F (20°C to 22°C) is considered ideal for most households, as it allows for a balance between energy efficiency and comfort.

This temperature range is supported by various studies, including one that found that 72°F (22°C) is the most comfortable temperature for sleeping. On the other hand, temperatures above 75°F (24°C) can lead to increased energy consumption and discomfort.

For every degree of temperature change, energy consumption can increase by up to 6%. This is why it's essential to find the sweet spot that balances comfort and energy efficiency.

Room temperature is a relative term, as it can vary significantly across cultures and seasons. Typically, it falls between 20-22 °C (68-72 °F), but the World Health Organization recommends maintaining at least 18 °C (64.4 °F) indoors for healthy individuals.

For healthy adults with appropriate clothing, humidity, and other factors, the range between 18-24 °C (64-75 °F) isn't associated with health risks. However, temperatures lower than 16 °C (61 °F) with humidity above 65% can be hazardous to respiratory health.

The ideal temperature for different rooms also varies. For living areas, 19 °C (66.2 °F) is recommended, while bedrooms should be kept cooler at 16-17 °C (60.8-62.6 °F) to promote better sleep. Bathrooms should be at 22 °C (71.6 °F) to prevent discomfort after bathing.

Here's a summary of recommended temperatures for different rooms:

Room temperature is a range of temperatures that feels comfortable for humans, typically between 20-22 °C (68-72 °F), according to the American Heritage Dictionary.

This range is considered ideal for maintaining a comfortable body temperature, which is around 37ºC (98.6 °F). Our brains work hard to keep our bodies at this temperature, making us burn glucose to warm up and produce sweat to cool down.

The World Health Organization recommends maintaining at least 18 °C (64.4 °F) indoors for healthy individuals, and 20 °C (68 °F) for infants, the elderly, or those with health conditions.

Temperatures lower than 16 °C (61 ºF) with high humidity can be hazardous to health, especially for people with respiratory conditions.

Living areas like living rooms and dining rooms are best at 19°C (66.2°F) for sedentary activities, according to the French Environment & Energy Management Agency (ADEME).

For older adults, slightly warmer temperatures of 20-22°C (68-71°F) are more suitable.

Bedrooms should be cooler, around 16-17°C (60.8-62.6°F), to promote better sleep.

The bathroom is best at 22°C (71.6°F) to prevent discomfort after bathing.

Encourage family members to wear warm clothing like sweaters and hoodies in the fall and winter to stay comfortable and save on heating costs.

The ideal temperature for a home can vary depending on the room. For living areas, the French Environment & Energy Management Agency recommends a temperature of 19 °C (66.2 °F) for sedentary activities.

This temperature range is suitable for most adults, but older people may prefer slightly warmer temperatures between 20-22 °C (68-71 °F). In contrast, bedrooms are best kept cooler, between 16-17 °C (60.8-62.6 °F), to promote better sleep.

Bathrooms, on the other hand, should be kept at a comfortable temperature of 22 °C (71.6 °F) to prevent discomfort after bathing. This is especially important to avoid health risks, especially if the bathroom is cold after a bath.

Here's a summary of recommended temperatures for different rooms:

By keeping your home at the right temperature, you can create a comfortable and healthy environment for yourself and your family.

Maintaining a comfortable indoor temperature is crucial for our health, especially for vulnerable populations like the elderly and young children.

The World Health Organization recommends a minimum of 18 °C (64.4 °F) for healthy individuals and 20 °C (68 °F) for infants, the elderly, or those with health conditions.

Cold air can inflame the lungs and inhibit circulation, increasing the risk of respiratory conditions, so it's essential to keep your home warm enough.

Temperatures lower than 16 °C (61 °F) with humidity above 65% have been associated with respiratory hazards, including allergies.

For the elderly, a cold room can have a significant impact on their health in just 45 minutes, decreasing their strength and affecting their safety and independence.

A study suggests a minimum temperature of 18 °C (65 °F) for seniors to stay healthy, especially during winter.

For babies, a recommended room temperature between 20 °C to 22 °C (68 to 72 °F) can reduce the risk of overheating and sudden infant death syndrome (SIDS).

Here's a quick reference guide to indoor temperatures for different rooms and populations:

Ultimately, finding the ideal room temperature is a matter of personal preference, but being aware of these guidelines can help you create a comfortable and healthy indoor environment.

The ideal temperature in your home depends on the room, not just the type of HVAC system you have. The French Environment & Energy Management Agency (ADEME) suggests different temperatures for various rooms.

For living areas like living and dining rooms, ADEME recommends a temperature of 19°C (66.2°F) for sedentary activities. Older adults, however, may prefer slightly warmer temperatures between 20-22°C (68-71°F).

Cooler temperatures in bedrooms promote better sleep, as the body's core temperature naturally drops during rest. ADEME suggests keeping bedrooms at 16-17°C (60.8-62.6°F) with appropriate bedding.

Bathrooms require a unique temperature, as they're often unused but need to be comfortable when used. ADEME recommends a temperature of 22°C (71.6°F) in bathrooms to prevent discomfort after bathing.

The type and size of your HVAC system can affect its efficiency, but the same general temperature recommendations apply. Systems that are over- or undersized will run inefficiently, leading to higher heating and cooling costs.

Here are the recommended temperatures for different rooms, based on ADEME's guidelines:

As you try to find the perfect indoor temperature, it's easy to get it wrong. Setting your thermostat to a warmer temperature than you want in hopes of warming up faster won't actually speed things along and will just result in overspending on your energy bills.

To avoid this common thermostat mistake, simply set your thermostat to the temperature you want it to be. Don't try to cheat the system!

Here are some ideal temperatures for different rooms in your home, based on guidelines from the French Environment & Energy Management Agency (ADEME):

By following these simple tips, you can create a comfortable and energy-efficient indoor environment.

Room temperature is a range of temperatures considered comfortable for humans, typically between 20–22 °C (68–72 °F), but it can vary significantly across cultures and seasons.

The World Health Organization recommends maintaining at least 18 °C (64.4 °F) indoors for healthy individuals, and 20 °C (68 °F) for infants, the elderly, or those with health conditions.

If you're not feeling hot or cold while wearing ordinary indoor clothing, you're likely within the room temperature range. This is important because our brains work hard to maintain a body temperature of 37ºC (98.6 °F), and extreme temperatures can pose health risks.

In fact, temperatures lower than 16 °C (61 ºF) with humidity above 65% have been linked to respiratory hazards, including allergies.

To get an accurate reading of the temperature in your home, it's essential to position your thermostat correctly. Avoid placing it in locations that see frequent changes in temperature or humidity, like the kitchen or bathroom.

Instead, place your thermostat on an interior wall in a location like your living room, where the temperature is more stable. This will help your thermostat give you an accurate reading of the temperature in your home.

If your thermostat supports external room sensors, consider placing sensors in other locations, like a bedroom, to better regulate the temperature in the rooms where you spend most of your time.
