Well, teachers, welcome to the damn club:
MUNCIE — Like many Americans, teachers are running on a less than an optimal amount of sleep.
That lack of sleep could affect classroom teaching, according to a preliminary study by a Ball State University professor.
[. . .]
According to the analysis, a quarter of the 109 Delaware County teachers surveyed reported their teaching skills were diminished because of sleep deprivation. Half said they made errors because they lacked sleep. Sleepiness also caused teachers to be grouchy and forget words.
For what it’s worth, I can offer the teachers a bit of advice from my own school days. There was always at least one class in which it was possible to sit in the back row and catch a 5- or 10-minute nap.
Oh, wait . . .
