In this video we'll be scientifically testing one of the most advanced and expensive sleep devices on the market - the Eight Sleep Pod 3 Mattress and Cover. As someone who's personally struggled keeping the right temperature during my sleep for years, the Eight Sleep Pod 3 is the device that has positively affected my sleep quality the most. The Pod 3 actively heats and cools your mattress throughout different phases of your night, aiming to create a better sleep environment, and it also has a bunch of sensors that track important metrics like your sleep stages, heart rate, and heart rate variability without having to wear anything on your body. But with a price tag of at least $2,000, and probably even more, is it worth it? In this video, we're going to focus on testing the accuracy of the Eight Sleep Pod 3's sleep tracking capabilities. We'll be comparing its measurements to different reference devices, in this case an EEG device that measures brain waves, and an ECG device that measures the electrical signals of the heart. By doing so, we'll get a better understanding of just how accurate and reliable the sleep tracking technology in the Eight Sleep Pod 3 really is. Finally, I will also share some of my subjective experiences with the heating and cooling functionality of the Eight Sleep Pod 3, to give you a complete picture of how the Eight Sleep Pod 3 performed. So, whether you're just curious about the Eight Sleep Pod 3 or just looking for a way to improve your sleep, this video is for you.

Now, for those of you that haven’t heard of Eight Sleep yet, let me briefly introduce what it is, what it aims to do, and how it works. The idea behind the Eight Sleep Pod 3 is that by manipulating the temperature of your sleeping environment you can improve your sleep. Basically, your core body temperature plays a very important role in helping you fall asleep and also in keeping you asleep throughout the night, and Eight Sleep wants to help you optimize this. Let me show you what that looks like.
