Having recently pulled an "all-nighter" while trying to fix a fatal bug in our release code, I started thinking of any health risks that I might have.

What are the adverse effects of staying up for staying up for 42 hours, considering I took no caffeine or other stimulants, as well as no depressants such as alcohol?

Upon googling I found a lack of facts, what would be good is a list of effects and rough times that they start happening. And any significant problems I would face, but moreover I would like to know what causes them? Unfortunately I only studied Biology until GCSE (UK - SAT/TAKS Alternative) and might need some simplified explanations or links to help understand more complex tasks.

I'm not even sure if this question is grammatically correct, and my brain power has slowly dwindled, should I be worried? I have read this and understand it to a vague extend.

Something that I know is that it affects memory negatively. If you search google scholar then you'll get a lot of articles on sleep deprivation experiments. –  WYSIWYG Aug 20 at 5:06
    
I've never heard of google scholar before. Thanks for pointing me in that direction! It seems a cool google sub-site. Also thanks for the information on more sleep deprivation experiments. –  Popey Gilbert Aug 20 at 5:36
    
Personally, I notice that most cognitive effects of sleep deprivation become very strong during times in which I would be habitually asleep, and minimal when I would awake normally. Arousal also seems to minimize perception of sleepiness, while being idle/bored makes it worse. You don't seem to have experienced this, your symptoms just get worse and worse. –  Superbest Aug 20 at 20:03

I noticed it worst when I was actually having a shower Superbest - Not sure if it was the heat that made be drowsy or what. I guess I did Eastman, however why this is caused was not answered, and whether there are any lasting effects. –  Popey Gilbert Aug 21 at 13:42

1 Answer 1

Upon not receiving an answer, I decided to post my own findings of symptoms I felt.

14 hours - Feeling tired.
19 hours - Feeling confused.
22 hours - Struggling to concentrate for long periods.
27 hours - Getting paranoid, continuously peering behind me.
36 hours - Going from paranoia to imagining things.
42 hours - Slightly concerned of the dark, a fear I've never had before.

I might post more detailed findings after getting some sleep, I'm finding it hard to conjugate words together.
