For a large segment of women, checking Facebook has become a primary part of their morning routine, with the act of scrolling through status updates the first thing they do when waking. In a poll last month of 1,605 U.S. adults who use social media, 34 percent told NBC Universal’s Oxygen Media Facebook comes before brushing their teeth and nearly 40 percent are self-described “Facebook addicts.” The survey also found that 26 percent of women 18- to 34 get up in the middle of the night to read text messages and 37 percent of that group say they have fallen asleep with a PDA in their hands.
