You may have read this here in 2009:
There aren’t any firm figures on how many people actually do sleep in the buff, though Esquire claims that 31 percent of men and 14 percent of women decline to play the pajama game.
More recently, we have this:
Costa Mesa-based Anna’s Linens, which sells sheets and home decor, has released a bedtime survey of 3,700 people to draw publicity to National Sleep Day, Jan. 3.
Among the findings: 8 percent of Americans sleep naked, 74 percent wear pajamas and the rest are clothed in something else.
Not that I have any worthwhile personal data to contribute, but I suspect Anna’s local customers this is Orange County, after all might be understating the case just a bit, and Esquire’s respondents might be overstating it.
I looked at Anna’s available sheets, which sport thread counts from 200 to 1000. (I remember a set I bought from JCPenney in the 1980s, which seemed to have a thread count of 12; it has long since been retired.) For what it’s worth, I don’t bother with anything under 300 anymore.
