The Genetic Fingerprint of Sleep

Did you know your brain produces a unique electrical "fingerprint" while you sleep?

This pattern is so distinctive that in identical twins, their sleep brainwaves are almost exactly

the same. For many of these electrical traits, over 80% of the variation is determined

by your genetics rather than your environment. This means your DNA likely dictates

your sleep architecture, which includes everything from how much deep sleep you get to how your brain waves

synchronise throughout the night. While your habits certainly matter, your biological

blueprint is what sets the primary stage for every single night of rest.
