This temperature helps you save money and burn calories!

As we head into October and nighttime temperatures start to dip into the 50s and 40s, you might be tempted to blast the heat while sleeping.

But here’s our professional suggestion: Keep your home’s temperature set below 66 degrees at night.

Why? Well, first off, 65 degrees is scientifically proven to help you fall asleep. But beyond that, sub-66-degree temperatures can also help you:

  1. Burn calories
  2. Lower heating bills

We’ll explain below…

The link between colder temperatures and your metabolism

Apparently, sleeping in mild cold temperatures increases your body’s metabolic activity.

In fact, in a study supported by NIH (National Institutes of Health), participants saw a 10% increase in fat metabolic activity after a month of sleeping in mild cold temperatures (66 degrees Fahrenheit).

So why do colder temperatures help us burn calories? Well, in response to cold, our body’s white fat cells transform into brown fat cells. You see, white fat cells are designed to store energy but brown fat cells are designed to burn calories to produce heat.

So, when placed in colder temperatures, the human body increases its count of brown fat cells to produce heat and maintain our body’s temperature. In fact, in the same study mentioned above, participants not only saw a 10% increase in metabolic activity, they also saw a 42% increase in brown fat volume.

So by lowering the thermostat below 66 degrees, you’re increasing your body’s brown fat volume—the kind of fat that produces heat by burning calories.

The financial benefit to sleeping in colder temperatures

Sleeping in colder temperatures means that you can lower the thermostat at least 10 degrees every night (around 8 hours). And, according to, that equates to 15% savings on your winter heating bills.

You see, the lower you set your thermostat, the less work you’re demanding from your heater, which means more energy savings.

Here’s our suggestion for a fall/winter thermostat regiment:

  • Morning: Turn down the heat by at least 10 degrees before you leave for work. For example, if your home is usually set to 70 degrees, drop the thermostat to 60 degrees (or lower) before your leave the house.
  • Afternoon/Evening: When you get home, raise the temperature to a more comfortable temperature of 70-75 degrees.
  • Night: Before heading to bed, drop the temperature to as low as 56 degrees.

This schedule ensures that you’ll roll back the thermostat by at least 10% for more than 8 hours a day for optimal energy savings on your heating bills.

Not sure you’ll remember to turn down the thermostat at night?

Consider investing in a programmable thermostat. These thermostats automatically adjust the temperature of your home according to a pre-set schedule.


For example, you can program this type of thermostat to automatically lower the temperature of your home from 70 degrees to 60 degrees at 9 pm every night. You can even program the thermostat to automatically raise itself back to 70 degrees around 6 am so that when you wake up, the house is already at a comfortable temperature.

And the best part? According to, when you use programmable thermostats correctly, you can expect to save up to $180 every year.
