The snooze button on your alarm clock may not be the only casualty of a sleepless night. A new study of married couples suggests that when wives have trouble falling asleep, the quality of their relationship with their husband suffers. The longer it took women to drift off, the study found, the more likely both partners were to report negative interactions with their spouse -- such as feeling ignored or criticized -- the following day. The same wasn’t true for the men, however. The researchers found no relationship between the amount of time it took a husband to fall asleep and the couple’s interactions the following day. So why didn’t the husbands’ sleep affect next-day interactions, too?
