Can’t focus well after a poor night’s sleep? You are not alone. A small study at Boston’s Brigham and Women’s Hospital looked at 12 people during a one-month study in a sleep lab. Their sleep was cut dramatically, to a mere six hours instead of their customary ten to twelve hours. Later, when searching for pictures on a computer, their performance was slower.
According to Jeanne Duffy, who reported the study in the Journal of Vision, people who cut back on sleep, especially on a regular basis, may not realize how impaired they are.
