I think most recommendations are to get 4-5 sleep cycles a night, so the actual elapsed time will vary for individuals. The problem with chronic sleep deprivation is that you miss one or more cycles, It's like if you washed your clothes but skipped the rinse and/or spin cycles. Skipping a whole night of sleep and you're still wearing yesterday's clothes.
