FAQ
What time should I go to bed if I wake up at 6 AM? expand_more
If you wake at 6:00 AM, the best bedtimes are 8:45 PM (6 cycles, 9h 15m), 10:15 PM (5 cycles, 7h 45m), or 11:45 PM (4 cycles, 6h 15m). We recommend 5 or 6 complete cycles for optimal rest and recovery.
Why does the sleep calculator add 15 minutes? expand_more
The average person takes about 15 minutes to fall asleep after lying down. Our sleep calculator accounts for this so your sleep cycles are accurately timed from actual sleep onset, not just when you get into bed.
How many sleep cycles do I need? expand_more
Adults should aim for 5–6 complete sleep cycles per night (7.5–9 hours). Four cycles (6 hours) is acceptable occasionally, while 3 cycles (4.5 hours) should only be used in emergencies. Each cycle includes light sleep, deep sleep, and REM stages.
