Wall Street Journal: "Scientists are still searching in the dark for the secrets of sleep"

January 18, 2008

WSJ Science Journal writer Robert Lee Hotz describes the state of sleep research, citing current and former Harvard faculty members Jeffrey M. Ellenbogen and Matthew Walker (now at Berkeley).

"People have been trying to figure out why we sleep for almost as long as we have been conscious of being awake, tossing and turning in the dark.

After a few restless nights, most of us can't even think straight. We are less able to make sense of problems, make competent moral judgments or retain what we learn, even though studies show our brain cells fire more frenetically to overcome the lack of sleep. Lose too much sleep and we become reckless, emotionally fragile, and more vulnerable to infections and to diabetes, heart disease and obesity, recent research suggests."
