More than 4,600 people answered questions posed by public radio station WNYC’s “Clock Your Sleep” program, reports The Washington Post‘s To Your Health blog, and the station is offering help for their insomnia.

In an experiment that bears watching for both its public health and media implications, a New York City radio station has asked its listeners what literally keeps them up at night, and is offering to help.

WNYC is taking the initiative a step further by inviting participants to join one of three teams — each headed by a well-known personality from the station — to make changes that encourage more sleep.
