Why Do I Need A Smart Thermostats for Sleep?

Two reasons. To help you induce sleep before bed via temperature and to save money while doing it.

Zeitgebers are cues that your body receives and which it uses for certain processes, like controlling your energy levels and alertness, hunger or sleepiness.

Temperature is one of the strongest zeitgebers that let your body know it’s time to sleep. Along with a lack of light and sound, a drop in temperature makes you sleepy.

Did you know that light, sound, and temperature are the 3 most important environmental signals to your body for a good night’s sleep?

Now that you know a chilly home promotes sleep, you must make sure your temperature is slowly declining in the 2-3 hours leading up to when you want to fall asleep.

This is where a smart thermostat and a smart lighting system like Philips Hue can really help.

Before you Buy

There are many “high rated” thermostats you can buy online.

However, some of these reviews can be gamed and you might not know you have a bad thermostat until after you install it.

For this reason we recommend reviewing the following before you buy.

Compatibility with your HVAC System

Perhaps one of the most important things you need to consider is whether or not you can even have a smart thermostat.

Some thermostats require you to have a C wire, which is an extra wire used to provide a return path for continuous 24V power. Companies will normally specify whether this is required or not on their product pages.

Some newer manufactures also offer a compatibility checker tool.

If you are renting an apartment or home, not every landlord will allow it. Some have outdated hvac systems that these newer thermostats could break.

Features for Sleep Enhancement

The number one feature you need to pay attention to is the ability to set schedules.

If you can set schedules by the day, that is the best as you may want the temperature setting different on your days off, especially when you see how sleepy you get as the temperature gets lower.

The sleep temperature should lower 2-3 hours before sleep and then rise an hour before you wake up.

Brand Dependability

There are many brands out there and a lot of them suck.

As we mentioned briefly above, reviews these days can be gamed. So we do not recommend going with a brand you have not heard of. Even if the brand has very high reviews on Amazon.

The brands we know are dependable when it comes to smart thermostats are Nest (Google), Honeywell, and Emerson.

These are all publicly traded companies that in some cases have been around since the 1800s.

Utility Rebates & Savings

When you use a smart thermostat, you are not only saving your money; you are saving your energy companies money as well.

Your power company may be handing out rebates to get a smart thermostat. Check the below links:
