What Is The Ideal Room Temperature for Comfortable Living?

Essentially, your body needs different room temperatures at different times of the day to feel comfortable.

Standard Room Temperature

It’s hard to tell what the actual standard room temperature is as people’s preferences vary. Nonetheless, the average range is somewhat between 68℉ to 76℉.

In the summer, you would want the room to be at around 68℉. On the other hand, some prefer to keep the standard temperature at right around 70℉ in the winter.


Another factor that you should consider when choosing seasonal room temperatures is where you’ll spend the most time around.

For example, if your bedrooms are on the highest story of the house, and the thermostat can only adjust the temperature for the whole house, you’d want to keep it at around 65 – 68℉ to cool down the rooms.

By doing this, the bedrooms are not overheated later on as heat rises at night.

Nonetheless, at the end of the day, what matters most is your preference. You can be one of those folks who love wearing shorts and rocking a wife-beater chilling around the house. Consequently, it will be a good idea to remain the thermal reading a little higher.

Otherwise, if your preferable homewear is hoodies and sweaters all day, it is wise to have the temperature turned down one or two degrees.

Best Room Temperature for Sleeping

Rumor has it that higher temperatures are better for sleeping. In fact, it was proven to be the opposite.

According to the National Sleep Foundation, cooler temperatures can make a significant difference to your sleep quality. To be more specific, cool room temperature assists in getting a good, deep night’s sleep after a long working day.

The ideal room temperature when sleeping ranges from 60 to 75℉. Essentially, your body kicks off its internal thermostat at night time, which is to lower the body temperature down by some degrees.

Nonetheless, the process cannot be carried out if the external temperature is too hot or cold.

Why You Should Have More Control Over Your Room Temperature

Temperatures can have an impact on your state of mind.

Can you recall the last time feeling so much better after a hot bath or a cold shower? Similarly, if the room temperature is too hot or cold, your body will instantly react to notify you of something wrong.

As a result, it is compulsory to keep the room temperature at a certain degree range for your body to be in its comfy zone.

Can Your Phone Tell The Temperature?

Absolutely! In fact, smartphones have several interior thermosensors used to measure the temperatures of the phone battery.

Nonetheless, trusting a device that continuously gets hot and cools down to measure ambient temperature is rather tricky. For that reason, manufacturers have come with ways to reduce the influence of the device’s own temperature.


By utilizing the metrics from the internal sensors, your phone can cease with a close enough number to the real surrounding temperature. However, the idea is nothing novel to the tech world and its constant hunt for innovation.

For instance, Huawei offers Honor Play 4 Pro, with thermometers. To use this built-in thermometer, you must allow the device to cool off from any heat and leave it somewhere away from your hand, which is also a heat source.

As you might have guessed, the whole thing failed. Even if you follow the provided guide, the accuracy of the thermal read was still uncertain.

But the failure of Huawei did not stop app developers from turning your phone into a thermometer. But you may want to keep in mind that temperatures measured from phones cannot be 100% accurate.
