Counting sheep

Insomnia has probably always been with us, likewise sheep. The counting sheep technique, like other distraction exercises, is effective for some people who find it difficult to get to sleep.

We have evidence of this particular technique, of counting sheep as they are imagined in a field or jumping a fence, being used from at least 1854. That’s from Seba Smith’s Way down East; or Portraitures of Yankee life:

“He shut his eyes with all his might, and tried to think of sheep jumping over a wall.”
