Bedtime reading with a tablet or smartphone can interfere with a good night’s sleep, some studies and many anecdotal reports suggest. Now researchers have conducted a small experiment to test the idea. Volunteers in this study reported less sleepy in the evening , and less alert in the morning after using the electronic device.
One of the co-authors of this study concluded that these devices are not benign. They have biological effects on us. I recently blogged about the social (or antisocial) effects of these “handy” devices on our interpersonal relationships. Now we discover that we may be losing physiological energy as well. Our digital tools may be our new “best,” and most demanding friends.
Where would we be without them?
