Improve your sleep quality
Do you constantly wake up feeling tired, even though the clock shows you’ve had eight hours’ sleep? You’re not alone. Many people confuse the duration of sleep with its quality – and this is precisely the key: only those who sleep deeply, without waking frequently, feel truly recovered the next day.
Sleep problems often develop gradually, but can usually be significantly improved with small changes to your everyday life. Instead of reaching for pills, you can promote better sleep naturally with Proven tips. This applies not only to adults, but also to children, whose difficulties falling asleep often manifest differently and are more heavily dependent on routines. Particularly when, for example, a 2- or 3-year-old child refuses to sleep, it’s worth taking a closer look at typical causes and suitable strategies.
In this article, we’ve put together some strategies to help you improve your sleep quality – from smart sleep hygiene and relaxing evening rituals to diet and exercise.
What is healthy sleep
Healthy sleep means more than just sleeping ‘long enough’ – it’s the quality of your sleep that matters. It consists of three key factors:
- Sleep continuity – You sleep through the night without waking frequently and achieve a sleep efficiency of at least 85 per cent (time in bed versus actual sleep time).
- Sleep architecture – At night, the body goes through four to six cycles of light, deep and REM sleep. Deep sleep in particular (around 20–25 per cent of the total duration) regenerates the muscles, the immune system and memory; the REM phases consolidate memories and emotions.
- Feeling of refreshment – You wake up in the morning without feeling particularly tired, with no Headache or difficulty concentrating, and remain productive throughout the day.
People who frequently wake up before their alarm goes off, remain alert throughout the day and fall asleep within 15–20 minutes in the evening generally experience better sleep – regardless of whether they slept for exactly seven, eight or nine hours.

Sleep problems often develop gradually, but can usually be significantly improved with small changes to your everyday life. Instead of reaching for pills, you can promote better sleep naturally with these proven tips. The following 5 tips can help you wind down more easily in the evening – and wake up feeling more refreshed in the morning:
- Stick to fixed bedtimes and wake-up times – regularity is more important than duration
Studies show that consistent bedtimes and wake-up times (with a variation of less than 30 min.) increase sleep efficiency, shorten periods of wakefulness during the night and are even a better indicator of health than sleep duration alone. So, aim for the same times on working days and at the weekend to stabilise your internal clock and make it easier to sleep through the night. - Avoid blue light & introduce an evening digital routine
Turn down the brightness on your screens or put them away completely at least 60 minutes before going to bed: a meta-review of 35 intervention studies shows that artificial blue light inhibits melatonin release and prolongs the time it takes to fall asleep. Replace scrolling with a calming ritual (reading, journaling) to help your brain reliably switch to ‘sleep mode’. - Create a climate-friendly Bedroom
A temperature of 17–19 °C, complete darkness and noise levels below 30 dB promote Deep sleep and minimise micro-awakenings. Combine this with an ergonomic Mattress and good air circulation – together, these factors have been proven to improve perceived sleep quality in sleep laboratory trials. - Timing exercise and daylight wisely
A meta-analysis (2024) found that 30 minutes of moderate Training (e.g. a brisk walk, Yoga) on at least three days a week significantly reduces sleep disturbances. It’s even more effective with morning or mid-morning light: a 2023 study showed that 10 minutes of bright daylight early in the day strengthens the circadian rhythm and consolidates Deep sleep. - Relaxation techniques for nights spent worrying
If you still can’t fall asleep, a short session of progressive muscle relaxationcan also help, according to the study. This sequence of tensing and relaxation affects your whole body. The relaxation process lowers your blood pressure and heart rate.
What to do if you can’t sleep
- The 15-minute rule
Don’t lie awake in bed forever. If you’re still tossing and turning after about 15–20 minutes, get up quietly, go into another, dimly lit room and do something relaxing (read a book, listen to an audiobook, do some gentle Stretching). This ‘stimulus control’ technique separates your bed from being awake and can help you fall asleep more quickly. - 4-7-8 Breathing
Breathe in for 4 seconds, hold your breath for 7 seconds, breathe out for 8 seconds – repeat this four to eight times. This method can improve your sleep quality and significantly reduce the time it takes to fall asleep. - Park your thoughts
Jot down persistent to-do items or worries briefly on a notepad. Studies on cognitive distraction show that simply ‘outsourcing’ your thoughts reduces rumination and makes it easier to fall asleep again.
If you combine these mini-strategies with the previous Sleep hygiene tips, you’ll create a reliable contingency plan in case insomnia does catch you out.
Diet & exercise: Improving sleep through lifestyle changes
Before you turn to sleeping pills, it’s worth taking a look at your everyday life: diet and exercise influence your sleep-wake cycle more than many people realise. What, when and how you eat – as well as the type and timing of your Training – can measurably affect melatonin release, the proportion of deep sleep and the time it takes you to fall asleep. The following points show you how you can achieve significant improvements in your sleep quality with just a few small lifestyle adjustments.
1. Regular exercise – but at the right time
Just 150 minutes of moderate Training per week (jogging, Yoga, brisk walking) can significantly improve Sleep quality and reduce difficulty falling asleep. This was found in a large Chinese meta-analysis.
You should finish any intense interval or Strength training at least 2 hours before going to bed: in a study published in *Nature*, participants who completed their endurance programme in the early evening (6 pm) slept more deeply – whereas a late workout after 8 pm resulted in a longer time taken to fall asleep.
2. Daylight & micro-movement as melatonin boosters
Short bursts of light and brief activity breaks – e.g. 3-minute Mini-Workouts every 30 min – boost alertness during the day and prolong Deep sleep at night, as demonstrated by a BMJ study on evening ‘activity breaks’.
3. A smart carbohydrate snack
A study found that people who eat a simple carbohydrate-rich dish such as rice semolina around four hours before going to bed sleep on average twice as quickly (from 18 to 9 minutes). If, on the other hand, the same portion is eaten immediately before bed, it actually delays the time it takes to fall asleep.
Practical tip: Treat yourself to some porridge or rice with a banana in good time – but avoid pizza and the like just before midnight.
4. Sleep-promoting foods
Eat two kiwis about an hour before going to bed – in one study, participants slept much more peacefully and better afterwards.
In tests, even a small glass of sour cherry juice before bed reduced the number of times people woke up during the night.
This is how you can support your sleep with simple foods – without any tablets at all.
5. Caffeine & alcohol – two simple adjustments
A recent review in the MDPI Journal clearly shows that anyone who drinks coffee or energy drinks after 3 pm, or has a glass of wine in the evening, takes longer to fall asleep, has less rapid eye movement (REM) sleep and wakes up more frequently at night. If you cut back on both – no late-afternoon caffeine, and at most a small drink with your meal – you’ll find you sleep through the night much better.
In short: by combining moderate exercise, smart meal timing and sleep-promoting snacks, you’ll bring your body and internal clock into harmony – the foundation for healthy sleep and sustainable sleep quality.

Get out of bed after about 15 minutes, go into a darkened room and read for a short while or take some deep, calm breaths; don’t go back to bed until you’re really tired – this way, your brain will start associating the bed with Sleep again rather than lying awake.
Between 17 and 19 °C: this range helps your core body temperature to drop – a natural trigger for Deep sleep.

A short power nap of 10–20 minutes before 3 o'clock can boost performance without affecting your night-time sleep; longer or late naps, on the other hand, often make it harder to fall asleep.
No later than six hours before going to bed – for most people, this means after 2 o'clock in the afternoon – so that the stimulating effects of caffeine have largely worn off by the time you go to sleep.
Trackers provide a good overview of trends (sleep duration, regularity), but they are no substitute for a medical diagnosis; use them as a motivational tool, but pay closer attention to how refreshed you feel in the morning.
Yes: Regular exercise, a cool, dark Bedroom and completely avoiding screens before bed have been shown to promote longer periods of deep sleep.
If you have trouble falling asleep or staying asleep for more than four weeks, if daytime tiredness becomes extreme, or if you snore and experience pauses in breathing, it is advisable to seek advice from a doctor or a sleep specialist. Our tips are not a substitute for medical advice.
