I sleep more on weekends but analyze: is this helping or hurting? Map the weekend oversleep: sleeping 2-4 hours more shifts circadian rhythm. Calculate: does weekend catch-up create social jet lag that makes weekday sleep worse? Show me the catch-up trade-off: short-term recovery vs. rhythm disruption. Give me the optimal strategy: catch up without destroying rhythm. Include: whether weekend sleep-ins reset my schedule, how much catch-up is safe, and alternatives to long weekend sleep.
