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.
In general, the ideal room temperature and your home for both efficiency and comfort fall somewhere between 68° and 76°F.
Reduced Allergens and Mold: Cooler temperatures can help reduce the growth of mold and dust mites, which thrive in warmer, humid environments. Better Sleep: Many people sleep better in cooler conditions, as a lower body temperature can facilitate deeper sleep.
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.
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.
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.
“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.”
During heat waves, experts, including utility companies, recommend keeping your thermostat no more than 20 degrees cooler than the outdoor temperature. For instance, if it's 100 degrees outside, aim to set your thermostat to at least 80 degrees.
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.
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.
Condensation, damp and mould
Colder homes often have more problems with damp and mould. Damp can also cause deterioration of the building, making it harder and more expensive to repair.
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.
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.
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.
A core body temperature of 104 degrees Fahrenheit (40 degrees Celsius) or higher is the main sign of heatstroke. Change in mental state or behavior. Confusion, agitation, slurred speech, irritability, delirium, seizures and coma can all result from heatstroke. Change in sweating pattern.
They found a 5-to-10 percent drop in sleep efficiency when indoor temperatures rose from 77 to 86 degrees, he said. “The consensus among most scientists is that anything higher than 75 or 80 is bad for sleep and potentially detrimental to health,” Baniassadi said.
What should my AC be set at if it's 90 degrees outside? If the outdoor temperature is 90 degrees, it's recommended to set your thermostat between 75-78 degrees.
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 best approach is to set your vacation thermostat about 10 degrees higher (summer) or lower (winter) than you normally set it when away from home. This lowers the amount of time your HVAC system is running while you are away. In general, don't set it above 85° in the summer or below 50° in the winter.
Ideally you should heat your home to a temperature of at least 18 °C. This is particularly important if you have reduced mobility, are 65 or over, or have a health condition, such as heart or lung disease. Having room temperatures slightly over 18 °C could be good for your health.
Side sleeping helps prevent the airway from collapsing and can reduce snoring. "And so, all in all, sleeping on the side — perhaps with their head slightly elevated as long as that's comfortable — is a good way to sleep," says Dr. Krahn. Side sleeping also is recommended during pregnancy, especially the last trimester.
Cooler can be disruptive: Setting the AC too low can disrupt your sleep cycle and leave you feeling cold and restless. The goldilocks zone: Aim for a temperature between 18°C (64°F) and 22°C (72°F) for optimal sleep comfort.
