Sleep Cycle Calculator
What’s the perfect time to go to sleep and wake up in the morning?
To rise feeling fully regenerated, the average person needs to go through 5-6 cycles of Zzzs.
Sleep lovers, if only we could wake up feeling refreshed every morning at the end of a sleep cycle. But let’s face it, reality bites: work, kids, life… they all conspire to drag us out of bed, often with the help of an annoying alarm clock.
If you often wake up feeling groggy, it may not be because you didn’t get enough slumber but because your sleep cycle was interrupted. The trick is to plan your bedtime around your desired wake-up time and aim to complete your last full cycle before your alarm goes off. That way, you’ll be ready to tackle the day with a spring in your step.
When you’re in dreamland, your brain works hard to keep you snoozing soundly. It goes through different activity patterns based on your eye movements and muscle movement, also known as sleep cycles. There are four main stages of these cycles – the initial three stages of sleep are non-rapid-eye-movement (NREM) stages. The first two stages are considered light sleep stages, followed by the deep sleep stage in the third phase. And finally, the fourth phase is rapid eye movement (REM) sleep.
The first stage of a sleep cycle is typically a light sleep stage where you may drift in and out of sleep and experience slower brain waves. The second stage is also considered a light sleep stage, but your brain waves become more rhythmic, and your body temperature and heart rate begin to decrease.
The third stage is the deep sleep stage, where your brain produces slow delta waves, and your body becomes fully relaxed. Finally, you enter the rapid eye movement (REM) sleep stage, where your eyes move rapidly, your breathing becomes irregular, and your brain waves become more active. According to medical experts, this is also the stage where most of your dreaming occurs.
During a typical night’s shut-eye, you should go through about five to six sleep cycles, give or take, and they roughly last for 90 minutes. This means you should aim for around 7-9 hours of snoozing each night. Remember, the exact number of cycles can vary depending on the individual, as well as factors such as age, health, and lifestyle. So, don’t worry if you need more or less sleep cycles than someone else – it’s all about finding what works best for you and your body.
Ensuring you get enough sleep cycles each night is essential for allowing your brain and body to fully rest and recharge, which can help improve your overall health and well-being. Monday mornings, early school runs, and cold dog walks – when we’re not feeling our best, even the smallest tasks can feel like an uphill battle. So, let’s commit to prioritising catching Zzzs and aim for the optimum number of sleep cycles each night.
