BHLHE41

Most adults need between seven and nine hours per night, though a small percentage of the population, estimated at less than three percent, functions well on fewer than six hours.

These true short resters carry a rare genetic variant in a gene called DEC2, which appears to allow their brains to accomplish the restorative functions more efficiently.

Researchers at the University of California, San Francisco, identified the DEC2 mutation in two thousand and nine after studying a family in which multiple members naturally got only about six hours per night without any apparent negative effects.

A second gene associated with natural short duration, called ADRB1, was identified by the same research group in twenty nineteen, and it appears to increase the activity of certain arousal-promoting neurons in the brain.

For the vast majority of people who do not carry these rare mutations, chronically getting less than seven hours per night is associated with a long list of health risks, including heart disease, diabetes, obesity, and impaired immune function.

They have no daytime cognitive deficits, no mood dysregulation.

We've discovered this is genetically mediated mutations in genes like DEC2ADRB1 or BHLHE41.

So

they just have better machinery?
