How to Use Sleep Calculator From Terry Cralle

Now that we’ve determined all properties of quality sleep, let’s talk about the intuitive sleep calculator on our website. We made sure to include all of the necessary sleep-determining factors such as age, wake up time, and sleep time. Additionally, we included the sleep interval (cycle) which you can change from the average 90 minutes.

So how to use it?

Step 1: Select your age. There is a slider where you can choose an age from 1 year old to 70+ years old. Above, we said that age affects the amount of sleep so pick accurately. You can also choose the right sleeping amount for your toddler if they struggle with their sleep cycle.

Step 2: Select the time it takes you to fall asleep. On average, it takes an adult person to fall asleep within 15 minutes from laying down. For many people this time is different, so you can pick accordingly for you.

Step 3: Pick what you’re looking for. You can choose whether you want to calculate the time it takes you to wake up, or the time it takes you to fall asleep. If you pick at what time you go to sleep, the calculator will let you select the appropriate time to sleep and vice versa.

Lastly, there is an option to select the right sleep cycle. The default option to pick from is 90 minutes to complete a sleep interval, though this may differ from person to person. If you already use personalized sleep trackers, you can use the data from them to personalize your sleep intervals.

And voila, you can now calculate the right sleep amount. The results will give you four suggestions on when and how to optimize your sleep cycle and make it your routine. Sleeping after midnight isn’t always the best idea so the best thing you can do is aim for the sleep before midnight.

Sleep Calculator: More FAQs

Q: What is the right time to go to bed and wake up?

Experts recommend that the best times to sleep is between 10 pm and 6 am. However, any time between 8 pm and midnight can be a good time to go to bed. It’s not recommended to sleep after midnight, given that one hour of sleep between midnight accounts for two hours of sleep after midnight.

Q: Why do I wake up tired?

People wake up tired for a variety of reasons. However, if you notice that you sleep late, in a noisy environment or a hot room, you could notice that your sleep performance is affected. If you feel you’re too fatigued through the day, you could use an aid such as a sleep tracker app on the phone or band to measure your sleep performance. It’s also a good idea to visit a doctor and discuss possible sleep disorders.

Q: How much sleep is necessary for optimal performance?

We’re all different and our bodies dictate different requirements. Sleep also widely depends on age, so you can check the listing we wrote about above. Experts, however, recommend anywhere from 7 to 9 hours of sleep for adults.

Q: Can you measure naps with a sleep calculator?

Naps shouldn’t last more than 30 minutes, or you may feel too drowsy when you wake up, due to sleep stages exchanging. Note that most sleep trackers need at least 3 hours of data to measure sleep, so naps aren’t a good factor for determining how much sleep you need. This sleep calculator can be used to measure full sleep cycles.

Q: How to determine the number of my sleep cycles through the night?

Convert the hours of your average sleep into minutes and divide them by 90 minutes (which is the average sleep cycle.) Alternatively, you can use devices like smartwatches or band to determine the right number of sleep cycles and how long they last.

Q: Are there some external factors that affect our sleep?

It’s no secret that factors like noise, high temperature, brightness, and electronics affect the quality of sleep. The best thing we can do is to create a room ambient that is dark, cool, and silent. Also, avoid using electronics before bed.
