Why should you use a sleep calculator?
When we go to bed at night, we embark on a journey. 🧳
Our brain activity, breathing and body temperature change constantly during the night.
Although we don't move, we are very active. 🏃♂️
By the time we open our eyes again the next morning, our bodies have gone through several sleep cycles.
If we go through too few cycles or are awakened at the wrong point, it will have a negative impact on our rest, mood and performance throughout the day. 🌞
Getting enough sleep is just as important for your health as food and water.
In fact, getting the right amount of sleep can help prevent disease, boost immunity and improve mental health! 👩
Our sleep calculator will help make sure you get your bedtime right.
Once you know the best time to sleep, you'll know when to set your alarm clock to get just the right amount of sleep!
Day and night: the circadian rhythm
Circadian rhythms are 24-hour cycles that are part of our body’s internal clock. ⏰
These rhythms help our bodies prepare for environmental changes, including when we eat and sleep.
Because of our circadian rhythm cycle, our body begins producing melatonin when the sun has set (generally at around 9 pm). 🌅
This is the body's sleep hormone.
Melatonin helps regulate our sleep-wake cycle, promoting a consistent and quality night of sleep. 💤
Sunrise and light stop melatonin production, and the body begins to produce the stress hormone cortisol to prepare us for the coming day.
If you want to ensure you get a great night's sleep, using our sleep cycle calculator to sleep according to UK seasons and your circadian rhythm can help.
For instance, you might find waking up earlier in summer easier because the sun rises earlier, triggering cortisol production.
An earlier bedtime or sunrise alarm clock could help with this even further.
What is the best time to get up in the morning?
You’ll feel most rested when you get up at the end of a sleep cycle.
If, on the other hand, you are pulled out of sleep during the deep sleep phase, you will feel very tired.
With our sleep calculator, you’ll get up feeling ready to face the day! 😃
The sleep calculator shows you when you need to go to bed based on your wake-up time.
It makes sure you will have the time to go through enough complete sleep cycles to feel rested when you get up.
This allows your body and mind to recover overnight. 💪
We've also tested a few sleep gadgets to help with getting up at the right time.
Sleep calculator for kids
For young children, sleep is an important time to process the experiences of the day.
The younger the child, the stronger the stimuli they receive from their environment.
You can use our sleep calculator for kids and babies so you can get them to bed on time for a happy and healthy tomorrow.
Babies need more sleep
Newborns need the most sleep of any age group, totalling almost twice as many hours of sleep compared to adults. 👶
After all, babies are experiencing everything for the first time, and their brains need time to process these experiences. 🧠
The brain uses sleep to do this, which is why the amount of sleep needed is significantly higher for babies than for adults.
You can ensure your baby gets superior quality sleep with the best cot mattresses.

Sleep calculator for men
For restful sleep, it is important not to wake up in the middle of a sleep cycle.
However, many men wake up before the deep sleep phase due to breathing problems or loud snoring. 👃
Loud snoring is also a symptom of sleep apnea, which can significantly impact the quality of sleep and quality of life.
Men do, in fact, snore more than women.
According to a study by the American Academy of Sleep Medicine, habitual snoring has been found in about 24 per cent of adult women and 40 per cent of adult men.
Both men and women are more likely to snore as they age. 👴
In many cases, an anti-snore pillow can reduce snoring and improve the quality of sleep.
Better sleep hygiene and sleep habits, including showering, sleeping on clean sheets, and keeping a dark room, can help you get a great night's sleep.
