Background: Recently I have really messed up my sleep schedule due to my procrastination. The internet points to some very basic conclusions but I would like to see actual experiments on effects of sleep on cognitive functions.

Questions

  • What is the absolute minimum hours of sleep one needs to completely restore brain functionality to peak levels?
  • How much sleep is required for muscle rebuilding processes?
  • How does this amount of sleep affect learning process, memory recall, and ability to infer relationships?

vote to close: aside from being self-help, this question cannot be answered adequately. 'required' amount of sleep will vary with the individual, and is certainly not a step function. also, what are 'peak levels' of brain functionality? if we broaden the criteria required for an answer, then the question is simply asking for a review of sleep studies on cognition. – Jeff Nov 13 '12 at 4:08
