When I get up in the morning I really become angry and in bad mood. I also very irritated if nothing goes what I wanted but I get cool down after an hour later. So I was wondering why does that happen to me and anyone else have this issue.
I wake up to a bad headache, aching back and arms, waking angry is the least of my issue. Try sleep in a cooler environment, or slip into something comfortable before sleeping.
2 things: Maybe not enuf sleep. Or you Woke up too suddenly.(like someone screamed, poured water etc)
the first one is really normal for me especially if it's a work day, and if nothing goes the way I wanted I'd be more than just irritated. lol
Most problems related to your mood after waking up are normally psychological usually related to your habits before sleeping, or perhaps your environment being noisy or something related to that thus causing lack or uncomfortable sleep, another reason could be your bed or pillow, perhaps either or both aren't comfortable so by result your bad mood when you wake up
Who likes to be interrupted from there good night's sleep and have to leave there nice warm bad? No one!!! It's pretty normal to be a little grumpy waking up, especially if you don't feel well rested, or you like lying in a nice warm bed for a few minutes~
I see that everyone has said the possible reasons, so let me add more. Dream, you had a dream that made you angry but you can't remember it
When I'm awake, I just awake and know what I'm doing. I know if I'm mad or at peace when I awake, I know if I had a nightmare, I know if I experienced something within the dream. Sometimes I even remember my dreams. But to be angry when awake... waking usually affects your heartbeat it accelerates your slow beating heart when you are sleeping so you wake up. So it can be considered your fast heart beat is related to your emotion of anger. But usually waking up to fast or too early also hurts your heart.
Well, I wake up my brother every morning by turning on the light, throwing back his covers, slapping his cheeks, and then flicking his ears. But he doesn't get mad because I'm the oldest and I've been training him to be my slave sibling since he was 5.
