I sacrifice sleep for productivity but analyze: is sleep deprivation costing more? Map sleep hours and productivity quality. Calculate: if poor sleep reduces cognitive function by 30%, what's the productivity loss? Show me the sleep math: less sleep ≠ more time if quality drops dramatically. Give me the sleep investment: prioritize this much sleep for better waking productivity. Include: whether sleep deprivation is destroying my productivity, how much sleep I actually need, and if protecting sleep would make waking hours more productive.
