Coffee Proven To Keep You Alert

I smiled when I read the latest coffee study to come in.  Researchers in Sydney at the Swimburne University of Technology used a Optalert.

The device worn like eyeglasses measures drowsiness by length of eye blinking and how fast the eyes close when blinking.

The researchers tested 18-29 year-olds for drowsiness. The age group was picked because of their high rate of auto accidents while drowsy.

The study wanted to prove or disprove the theory coffee could keep people from falling asleep while driving an auto.  The group was divided in half with one group given a capsule of caffeine equal to two cups of coffee while the second group was given a placebo.

Both groups were tested using the Optalert. Those receiving the caffeine maintained alertness for about three hours with increased reaction time.  Reaction time is what decreases so dramatically when we get tired. So drinking coffee, espresso or other caffeinated drink to avoid getting drowsy while driving works.

I understand the need for scientific validation as previous studies were not consistent in their results.  But anyone who has ventured near University at exams would have drawn the same conclusion.

Not the usual grind,
