Sleep clinic.

A version of this article from the L.A. Times appeared in the Salt Lake Tribune this morning, headlined "If you sleep more, you may sneeze less."  Some highlights:

"The longer you sleep, the better off you are, the less susceptible you are to colds," said lead author Sheldon Cohen, who studies the effects of stress on health at Pittsburgh's Carnegie Mellon University.  Prior research has suggested that sleep boosts the immune system at the cell level. This is the first study to show small sleep disturbances increasing the risk of getting sick, said Dr. Michael Irwin. 

and 

The people who slept less than seven hours a night in the weeks before they were exposed to the virus were three times more likely to catch a cold than those who slept eight hours or more.

 and finally 

Sleeping fitfully also was tied to greater risk of catching a cold. Those who tossed and turned more than 8 percent of their time in bed were five times more likely to get sick than those who were sleepless only 2 percent of the time. 

So:  if you sleep seven hours, you're basically saying to the virus, I want you for my very own.  Sleeping fitfully?  It's like a mating dance you're doing for the virus.  And the advice of the experts:  "The message is to maintain regular sleep habits because those are really critical for health," Irwin said. 

No, let me just repeat that in case you missed its perspicacity, and in a larger font size, and indented: 

"The message is to maintain regular sleep habits because those are really critical for health," Irwin said. 

Oh, thank you.  How very helpful.  I will telepathically communicate my gratitude for this advice to the researchers tonight, while I'm tossing and turning during my less than eight hours of sleep.
