Does "play havoc with" mean "Having a bad effect" in this sentence?
the Sentence:"Sub-optimal amount of sleep can play havoc with our emotions."

    then, If somebody say ' some people wreak havoc with their bad judgement', what does that mean exactly? Doe it mean that people try not to make bad judgement?

    Wreak havoc = play havoc.
    Some people have such a bad sense of judgement that they cause confusion/distress/disaster wherever they go.
