In a previous post, I wrote about why people get angry. There’s a fairly predictable pattern based on your mood, the provocation, and your interpretation of that provocation (which is influenced by your mood). What follows all that is the anger response which can look a lot of different ways (anything from suppression to appropriate assertion to violence).

I’m not encouraging you to go to bed angry. You’ve probably heard not to do that and that’s actually pretty good advice. However, getting regular, healthy sleep is an important part of managing anger.
A lack of sleep diminished activity in the area of the brain- the frontal lobe- associated with impulse control. Consequently, sleep deprivation makes it harder to control your angry impulses and you’re more likely to do something you regret when you get angry.
