Relationship Between Extremes In Sleep Duration And Increases In Abdominal Fat In Minority Young Adults

Goldilocks research.

A study in the March 1 issue of the journal SLEEP shows that African-American and Hispanic young adults with short or long sleep durations had greater increases in belly fat over a five-year period compared with those who reported sleeping six to seven hours a night.

Note that both "too much" and "too little" sleep are the culprits.

Also note what is considered "extreme."

More than 7 hours sleep is "extreme."

So much for the 8 hours per night.

There will never be a way to "get it right" as long there is money for crappy research.
