When sleep patterns diverge, it’s harder to keep a connection, reports Psychology Today.

There are many ways to “drift-proof” your relationship, such as regular date nights,surprising each other, filling each other’s “emotional bank account,” or thanking each other. However, one of the easiest habits to adjust is to go to bed at the same time, at least a few nights a week, with plenty of time to connect before falling asleep. But research shows that a full 75% of couples do not go to bed at the same time, usually because one person is surfing the web, working, or watching TV.
