If you want to go to bed now...

Bedtime

The average human takes 15 minutes to fall asleep.

To wake up refreshed at  6:30 AM , you need go to sleep at one of the following times:

If you go to sleep right now, you should try to wake up at one of the following times:

If you wake up at one of these times, you’ll rise in between 90-minute sleep cycles. A good night’s sleep consists of 5-6 complete sleep cycles.

How to Use the Sleep Cycle Calculator

Our Sleep Cycle Calculator is designed to help you align your sleep with your natural 90-minute sleep cycles. Waking up between cycles, rather than in the middle of deep sleep, helps you feel more alert and less groggy.

Wake-up Time: 6:00 AM

It takes the average person about 15 minutes to fall asleep. To ensure you wake up at 6:00 AM feeling refreshed, you should aim to be in bed and asleep by one of the following times:

  1. 9:45 PM (for 7.5 hours of sleep, 5 cycles)
  2. 8:15 PM (for 9 hours of sleep, 6 cycles)
  3. 6:45 PM (for 10.5 hours of sleep, 7 cycles)

If you go to sleep at one of these times, you'll complete full sleep cycles and rise at 6 AM at the end of a cycle, not in the middle of deep sleep.

Understanding Sleep Cycles

A good night’s sleep consists of 5-6 complete 90-minute sleep cycles. Each cycle includes stages of light sleep, deep sleep, and REM (dream) sleep. Waking up between these cycles, when your sleep is lightest, is the secret to feeling refreshed.

Frequently Asked Questions (FAQ)

Why is it so important to wake up between sleep cycles?

Waking up in the middle of a deep sleep stage can cause sleep inertia, leaving you feeling groggy and disoriented for hours. By timing your wake-up to occur between cycles, you arise from a lighter sleep stage, making it easier to start your day alert and energized.

How many sleep cycles do I actually need?

While individual needs vary, most adults need 5-6 complete sleep cycles per night, which equates to 7.5 to 9 hours of sleep. This allows your body and brain enough time to progress through all the necessary restorative stages multiple times.

Can I use this calculator if I go to bed late?

Absolutely. Whether you're an early bird or a night owl, the principle remains the same. Just enter your desired wake-up time, and the Sleep Cycle Calculator will provide the best bedtimes based on full 90-minute cycles, plus the 15 minutes it typically takes to fall asleep.

What if I don’t fall asleep in 15 minutes?

The 15-minute estimate is an average. If you know it usually takes you longer to fall asleep, simply adjust your bedtime earlier by that amount. For example, if it takes you 30 minutes, aim to be in bed 15 minutes earlier than the time provided by the Sleep Cycle Calculator.
