What is the minimum amount of sleep you can function on?Watch this thread
I can manage about 5 hours before a working day. Don't know how I do it tbh
Post-baby - 2-4 hrs
Based on a documentary's experiment I watched once, here's its answer:
Assuming 'to function' means being able to have normal concentration and motor function, then the minimum amount would be around 6 and a half hours (6.5). Any less sleep and you will likely not function efficiently or optimally, i.e. your reactions will be slower, your logical thinking will be impaired
This could be seen in the experiment:
One group of people slept 6.5 hours and the other group 8 hours and one off-guy who slept 5.
Both were asked to perform quite simple tasks that require logical thinking, as well as basic chores and finally some arithmetic.
The results were: the guy that slept 5 hours was like a 2 year old. He couldn't think straight, he couldn't even remember or figure out basic arithmetic anymore (simple parentheses rules), while he knew he would be able to solve that math problem in 2 seconds if he would have slept more; he was perplexed of his lack of logical functioning. He even messed things up with basic chores, which led him to go back and forth a few times. Normally he wouldn't have had any problems with this at work, but now he did.
The people who slept 6.5 hours did ok, but not spectacularly fast. They paused a bit when thinking about the arithmetic and they weren't all too active when doing the chores.
The guys that slept 8 hours, oh man, those were fully and fluently functioning! They could solve the arithmetic in 1 second, quickly and dynamically take care of the basic chores they were put up to and finished 15 minutes earlier than the guy above.
As for my own experience, if I lack sleep, I might just as well not go to class because I will not understand or remember a single thing. This has happened to me some times. All you can think about is sleep and food then.
In other words, lack of sleep is the same as attending class while being loaded drunk. The physical presence is there, but the mental one is not.
Always make sure you are bright and fresh, with the optimal amount of sleep so that you can absorb everything from your classes!
many all nighters during darker thoughts lol
