FAQs
What time should I go to bed if I wake up at 7 AM?
A common cycle-based target is around 9:45 PM or 11:15 PM, depending on whether you aim for 6 or 5 cycles, with 15 minutes to fall asleep.
Why does bedtime matter for sleep quality?
Going to bed at a consistent time aligned with your wake-up target supports circadian rhythm and can reduce morning grogginess.
