What Is Ideal Temperature In the House and Why?

Are you trying to find that ideal temperature setting that is going to keep you warm in the coldest winter and cool during a boiling hot summer?

Typically, temperatures between 68 and 78 F are considered ideal for the indoors and 60-67 F is the best range for sleeping. During the winter, you might want to keep the temperature at 68 F and in the summer – at around 78 F to lower your energy bills.

What Is Ideal Temperature Inside the House and Why?

The ideal house temperature lies between 68 and 78 F. Such a temperature setting will not only make you feel comfortable but will also help your HVAC system be as efficient as it can possibly be.

Keeping the temperature inside your house in this range is recommended, but, in some situations, a lower or a higher temperature might work better.

  • Health conditions and age

People with various health conditions, as well as the elderly and small children may prefer higher temperatures.

  • Humidity level

High humidity makes you feel hotter. For example, if the humidity if 70% and the indoor temperature is 83 F, you are going to be feeling as if it’s 88 F.

At the same time, the drier the air, the more moisture is going to evaporate from your skin making you feel colder than it’s actually is.

So, you might want to change the temperature on your thermostat, if the humidity level is not appropriate. Or consider buying a dehumidifier (humidifier).

  • House size, orientation, and layout

You might want to lower the thermostat’s setting if you spend a lot of time in the south-facing room.

Empty rooms cool off much faster, while rooms that have plenty of furniture in them might feel warmer for a longer period of time.

  • Thermostat location

A thermostat located in direct sunlight will measure the wrong average temperature. As a result, your house will feel a lot colder than it actually is (though the thermostat might be showing that the temperature is fine).

What Is the Best Temperature for Sleeping?

Keeping your bedroom dark, quiet, and cool will help you enhance your sleep. Experts agree that a temperature between 60 and 67 F is perfect for a good-quality sleep.

Tip: the optimal sleeping temperature for babies is between 65 and 70 F.

If the temperature in your bedroom gets too high or too low, you are more likely to wake up.

Hot temperatures are a bigger disruptor of our sleep. If your bedroom is over 70 F, it means that it’s too hot and that you’ll experience trouble falling and staying asleep.

Cold temperatures do not disrupt the sleeping cycles as much, but if the temperature is way too low, your body is going to try and do its best to stay warm. As a result, a lot of extra pressure will be put on your cardiovascular system.

Hint: avoid eating foods high in sugar or drinking caffeine before bedtime. These products will increase your body temperature and will make you feel hotter.
