Image by tinacris See, I have a bad habit. I like to check my iPhone the second I wake up. I kept the smartphone by my bed on the night table. But as a result, I became less rested, more anxious, and more stressed out. I’m not alone. A whopping 54% of U.S. smartphone users said they check their phones while lying in bed; before they go to sleep, after they wake up, even in the middle of the night. This compulsive habit reminds me of cigarette smoking.
