Sharing everyday good news with your S.O.—like the personal record you broke at the gym, or the compliment you got from a colleague—won’t just strengthen your bond. It may help you sleep better, too, according to researchers. That is, as long as your partner celebrates the happy news along with you, and doesn’t just brush it off. The new study builds on previous research that shows how being in a supportive relationship can improve psychological health, partner intimacy, and overall sleep patterns.
