Your Genetic Sleep Fingerprint

Did you know that the electrical patterns of your brain while you sleep are as unique as your thumbprint?

While our daily habits—like when we go to bed or how long we sleep—are about 20% to 50%

genetic, the actual electrical activity of your brain, measured by an EEG,

is one of the most heritable traits in humans. Research shows this "sleep fingerprint"

is up to 98% determined by your DNA. These patterns are so consistent that scientists can identify

an individual just by looking at their non-REM sleep waves, regardless of how tired they were

before the test. Essentially, while your lifestyle influences your schedule,

your biology dictates the deep, internal structure of your rest. We’re exploring
