Why does lack of sleep make a person irritable? (Physiology aspect)
In: Biology
Essentially, when you’re tired, your brain wants you to go the fuck to sleep, yeah? Well, it tries to figure out why you aren’t going the fuck to sleep and one of its first guesses is that you’re being threatened, so it amps up your aggression, basically it makes you angrier so you can scare off what ever the threat is. Your brain sees a problem, lack of sleep, comes up with a reason, threat, and employs a solution, aggression. This was explained to me by my AP Psych teacher two years ago, so it maybe spotty.
