Meir Kryger, MD, professor of medicine at the University of Manitoba in Winnipeg, Canada, says people who don't sleep well can exhibit the following symptoms:
· Frequent sleepiness
· Nodding off at meetings or while driving
· Difficulty with concentration
· Lapses in memory
· Poor performance, worse than usual
· Mood changes, such as being more snappy and irritable
If we don't get enough sleep, our performance on the job suffers and can affect those around us as well.
