Sally Kohn: We've all had an idea of, you know, I didn't sleep very well. But what about the impact of these devices and the perception versus the actual amount of sleep? She says there are good laboratory studies in sleep labs that show when you ask somebody how good was their sleep last night on say a one to four scale from one very poor to four very good,. That actually individuals are very good at rating the quality of their sleep compared with objective polysomnography measures.Kohn: It's just a question of how you choose to use it and interpret it.
