Well + Good: One of the other effects of going to sleep angry is that it’s possible to set yourself up for a vicious cycle.

“If you’re angry at someone, especially as it gets later in the night, you might begin stressing about how much sleep you’ll be able to get,” says Dr. Wu, adding that sometimes, the thought of compromised sleep can be more stressful than the actual argument. “If you are in this situation, talk to the other person, and schedule a time to talk the next day,” she adds. Of course, being able to go this route requires the argument at hand to be low-stakes enough to feel comfortable tabling until the agreed upon time. But, when it is a feasible option, taking it can make it possible to get rest without opening yourself up to risks associated with going to sleep angry, Dr. Wu adds.
