How does Dreem improve your sleep?

We’re pretty sure your first question about Dreem is, well, “How does it help me sleep?”

First, it’s important to understand where we came from. Dreem is derived from the same EEG (electroencephalogram) technology used in sleep labs around the world. This means the headband is able to record your brain waves to determine your sleep stage in real time. From there, our product Dreem triggers sound at precise moments.

How does that help? Because your inner ear is actually one big generator – it takes in sounds and transforms them into electrical impulses interpreted by your brain. We’ve found that making a precise sound, at a precise moment, can sync with your brain waves to stimulate deep sleep.

But how do these stimulations work? Dreem’s magic fits one word: music.

Think of your brain as an organic orchestra. When you fall asleep, the rhythms of its music slow down. In deep sleep, the tempo reaches their slowest point, at approximately 1 Hertz. It means that your orchestra is playing for half a second, quiet for the next half a second, and on and on. Dreem’s electrodes are able to record these “slow waves.”

Like most human beings, the instrumentalists in your brain are lazy. They want to play loudly, together, at the beginning of the night…and then take a break (ok, really a few breaks.) This progressively weakens the amplitude of your brainwaves, meaning you are more restless rather than restful. Worse, when you’re stressed (and when you get older) your brain orchestra gets even lazier – further dampening your brainwave amplitude, and resulting in poor sleep quality. This might not sound terrible, but poor quality sleep has a direct impact on memory troubles and even long term neurodegenerative diseases.

The Dreem headband is sort of a sleep conductor for your brain’s orchestra: keeping deep sleep in tempo, and sustained through the night. It uses a metronome ringing at accurate times to remind them when to play. This united symphony means your slow waves stay in the right rhythm and volume throughout the night, ultimately meaning that your brain can fully benefit from the positive effects of sleep.

The effects of these tiny music notes generated by Dreem headband can be directly witnessed on your EEG. It typically looks like this:

The curve that shows average deep sleep with stimulation in the diagram represents slow waves enforced by Dreem. The brain orchestra keeps on playing with a metronome, instead of taking (another) break. By amplifying your slow waves at the right moment, Dreem both extends and amplifies your deep sleep.

Nietzsche wrote in the Twilight of the Idols that a life without music would be a mistake. Well, a night without the right music might be too.
