How To Calculate 90 Minute Sleep Cycle
According to the 90-minute sleep cycle calculator, the ideal time to sleep is 90 minutes. This is because 90 minutes is the time it takes for our bodies to complete one sleep cycle. Our bodies alternate between two different types of sleep during a sleep cycle: REM (rapid eye movement) and non-REM. REM sleep is when we dream and our brains are active, while non-REM sleep is when our brains are resting.
Alternating between REM and non-REM sleep helps us feel rested and refreshed when we wake up. The 90-minute sleep cycle calculator can help you determine how much sleep you need to feel well-rested. Simply enter the time you want to wake up, and the calculator will tell you how many 90-minute cycles you need to complete to reach your desired wake-up time.
For example, if you want to wake up at 7 am, you would need to complete four 90-minute cycles, which means you would need to go to bed at 11 pm. Of course, everyone’s sleep needs are different, so it’s important to experiment until you find what works best. But if you’re looking for a general guide, the 90-minute sleep cycle calculator is a great place to start. We developed this helpful calculator to help you get the most accurate result for your cycle.
How To Use The 90-minute Sleep Cycle Calculator
Using the sleep calculator is easy. Simply enter the time you want to wake up and hit “calculate”. The sleep calculator will then tell you how many 90-minute sleep cycles you need to complete to reach your desired wake-up time. For example, suppose you want to wake up at seven o’clock. You would need to complete four 90-minute sleep cycles, which means you would need to go to bed at eleven o’clock.
What To Do If You’re Struggling To Get Enough Sleep

Most adults need between 7 and 8 hours of sleep per night, but many struggle to get the shut-eye. Suppose it’s hard for you to sleep or more often you wake up the next day feeling exhausted than ever or moody, it’s an indication that you aren’t getting sufficient sleep.
It is nothing permanent, though, but something you can work on. So here are a few things you can do to improve the situation.
Establish a Regular Sleeping Routine
One of the best things you can do to improve your sleep is establishing a regular sleep routine. Ensure you retire to bed and wake up simultaneously every day, weekends included. This helps to regulate your body’s natural sleep-wake cycle and make it easier for you to fall asleep and stay asleep. Also, try using the 90-minute rule sleep calculator to find out how much sleep you need. This will help you adjust your bedtime accordingly.
Create a Sleep Sanctuary
This is another ideal way to boost your sleep. Create a sanctuary for yourself. This means making sure your bedroom is dark, quiet, and relaxed. Consider using blackout curtains or an eye mask to block out light, earplugs or a white noise machine to drown out the sound, and a fan or air conditioner to keep the room cool.
Limit Caffeine Intake
First, take a look at your sleep habits and see if there’s anything you can change. For example, are you going to bed at a reasonable time? Are you using electronics in bed? These things can disrupt your sleep and make it harder to fall asleep. If you’re struggling to sleep, try to limit your caffeine intake. Caffeine can stay in your system for eight hours, so avoid drinking coffee or tea after lunchtime.
Do Some Exercise
Exercise is another excellent way to improve sleep. Not only does it help to reduce stress and anxiety, but it also tires out your body and makes you sleepy. Just be sure not to exercise too close to bedtime, as this can have the opposite effect.
Try Relaxation Techniques
There are several relaxation techniques you can try to help you sleep better. These include deep breathing exercises, progressive muscle relaxation, and visualization. If you’re struggling with anxiety or stress, these techniques can also help to reduce these feelings.
If you’re still struggling to sleep, it’s essential to talk to your doctor. They can rule out any underlying medical conditions and help you find the best treatment for your sleep problem.
How To Make The Most of Your Naps

Napping can be an effective way to boost your energy and mood. But if you want to get the most out of your naps, there are a few things you should keep in mind.
Make Your Bedroom Dark and Quiet
First, locate a quiet and dark place to lay down. This will help your body relax and make it easier to fall asleep. If you can’t find a dark room, try using an eye mask or blackout curtains. And if you’re trying to sleep during the day, consider using earplugs or a white noise machine to block out sound.
Be Consistent
Try to nap each day simultaneously to help regulate your body’s sleep-wake cycle. Napping this way will make it easier for you to fall asleep.
Choose the Right Length of Time
How long you should nap depends on how much sleep you need. If you’re trying to make up for lost sleep, aim for a 90-minute nap. But if you’re looking for a quick energy boost, a 30-60 minute nap should suffice.
