The Philadelphia Inquirer asks: What does this booming sleep-aid industry mean for consumers in desperate need of some shut-eye?

Most doctors say folks struggling with sleeplessness should use what works best for them, but consumers should know that even as technology advances, the advice from experts on what constitutes good sleeping habits hasn’t changed in years: Stick to a routine. Sleep in a cool, dark room. Leave your phone out of sight. Avoid screens, booze, and big meals just before bed. Go to another dimly lit room if you can’t fall asleep.
