The Science Behind Good Sleep
Restful sleep is a highly complex biological process that goes far beyond simply "switching off". While we sleep, our body regenerates on a cellular level, strengthens the immune system and consolidates memories. But what exactly happens during sleep, and why is sleep quality so crucial to our well-being?
The different sleep phases and their functions
The human sleep cycle consists of three main phases that occur at approximately 90-minute intervals:
- Light sleep: In the first phase of sleep, the body slowly prepares for deeper rest. The heart and breathing rate slow down, the muscles relax, and the transition from wakefulness to sleep begins. This phase, which includes light sleep, creates a stable basis for entering the regenerative deep sleep phases.
- Deep sleep: The deep sleep phase is crucial for physical regeneration. During this time, the brain slows down its activity and growth hormones are released, which support cell repair and strengthen the immune system. These regenerative slow-wave sleep phases allow the body to fully recover and recharge.
- REM sleep (Rapid Eye Movement): During REM sleep, the brain is highly active while the body remains relaxed. Dreams occur and important processes such as processing emotions and consolidating memories take place. This phase plays a central role in emotional balance and memory formation.
The balance between these phases is crucial, as each phase has its own specific functions. Disturbances - whether caused by external influences or stress - can affect this balance and lead to long-term health problems.
The Role of Body Temperature in the Sleep Process
A key element for sleep quality is the regulation of body temperature. According to a study by the University of South Australia, the body's core temperature drops by about 1°C when falling asleep. This drop in temperature signals the brain to release melatonin (the sleep hormone), which makes the transition to sleep easier.
“Effective temperature regulation helps maintain an undisturbed sleep cycle and promotes the body’s recovery.” – University of South Australia
What happens when temperature regulation is disturbed?
- Too high temperatures: can lead to frequent awakenings and a shortened deep sleep phase, which impairs physical regeneration.
- Temperatures that are too low: Make it difficult to fall asleep because the body has to use more energy to stay warm.
The Effects of Light and Darkness
The circadian system – our internal biological clock – is significantly influenced by light. Blue light sources such as smartphones or screens suppress melatonin production and shift the natural sleep-wake rhythm.
Studies from Harvard Medical School show that people who are regularly exposed to blue light fall asleep later and have less restful sleep. Darkness, on the other hand, signals to the brain that it is time to switch to rest mode.
The psychological component of sleep
In addition to the physical aspects, mental preparation for sleep also plays a crucial role. Stress and worry can increase the release of cortisol, a stress hormone, making it difficult to fall asleep. Practices such as mindfulness, meditation or journaling before bed can help calm the mind and promote sleep quality.
Factors that influence sleep quality
In addition to temperature and light control, there are other key factors:
- Air quality: A well-ventilated environment improves oxygen supply and reduces the risk of waking up due to poor air quality.
- Noise level: Constant exposure to noise can disrupt your sleep cycle, even if you don't fully wake up.
- Nutrition: Heavy meals before bedtime or caffeine can interfere with sleep. Studies show that a diet rich in tryptophan (e.g. in bananas or almonds) improves sleep quality.
The Art of Processing: How Linen Bedding Is Made
Linen is a material that has been valued for centuries for its natural benefits. It is derived from the fibers of the flax plant and offers a unique combination of durability, breathability and temperature regulation.
These properties make linen an excellent choice for bedding, especially for people who value healthy sleep. But before we delve deeper into the properties of linen, you will learn below how flax is turned into the high-quality linen fiber that we use for our bedding at kanela.
From Flax to Fabric: The Production Process of Linen
Flax cultivation
Flax is a hardy plant that thrives in temperate climates. It requires little water and no intensive fertilizers or pesticides, making it an environmentally friendly alternative to cotton. It is mostly grown in Europe, especially in countries like France, Belgium and the Netherlands, where the climate is optimal for the plant. In addition, flax binds CO₂ from the atmosphere and leaves only minimal residues, as the entire plant can be used - from the seeds to the stems.
Harvesting and roasting
The flax plants are harvested when they are fully mature. Unlike many other crops, the plant is not cut but pulled out of the ground with its roots in order to preserve the fibers in their full length.
This is followed by the roasting process, in which the stems are naturally decomposed by microorganisms. This separates the woody part of the plant from the soft fibers. This phase is often carried out by dew or water roasting:
- Dew roasting: The plants are spread out in the field where dew and microorganisms do the work.
- Water roasting: The stems are immersed in water to speed up the process.
Breaking and swinging
After roasting, the stems are dried and mechanically broken. During this phase, the woody part of the plant is removed to expose the pure linen fibers.
The swinging finally separates the last solid residues (the so-called shives) from the long, high-quality fibers. These long fibers are then processed into yarn, while the shorter fibers are used in the paper or textile industry.
Combing and spinning
The fibers obtained are then combed to smooth them and improve their quality. Combing ensures that the fibers are aligned parallel, resulting in a uniform yarn.
The next step is spinning, where the fibers are processed into threads. These threads can be spun in different thicknesses - depending on whether they are to be used for fine linen bedding or more robust fabrics.
Weave
The spun threads are processed on looms to produce the characteristic linen fabric. The type of weaving technique determines the structure of the material: from particularly tightly woven linen for linen bedding to loosely woven fabrics for curtains or clothing.
finishing and coloring
The raw linen fabric is finally cleaned and – depending on the intended use – bleached or dyed. At kanela, we attach particular importance to using only natural or environmentally friendly dyes in order to preserve the sustainable properties of the linen.
Linen is pre-washed at this stage to make it softer without losing its typical robustness. This stonewashing process is a popular step that gives the fabric a soft feel and a subtle, timeless look. The stonewashing process also offers a variety of benefits that make linen bedding even more attractive. Pre-washing makes the material particularly soft without compromising the natural properties of linen such as breathability and durability.
At the same time, this process ensures that the linen is already "pre-shrunk", which prevents unwanted shrinkage during the first wash. In addition, stonewashing gives the linen bedding its relaxed, casual look with a subtly structured surface that fits perfectly with a conscious and natural lifestyle. This finishing combines comfort, functionality and timeless style in one product.
Cutting and processing
After finishing, the linen fabric is cut and processed into linen bedding, curtains or other textiles. At kanela, we pay attention to precise processing and long-lasting quality so that every product meets the highest standards.
Composting and recycling of linen
Linen is not only environmentally friendly in its production, but also completely compostable at the end of its life and can be reused in many ways. Here are the ways in which the remains of the flax plant and old linen fabrics can be disposed of sustainably or reused:
Composting of linen products
Pure linen fabrics are biodegradable because they are made from 100% natural plant fibers. This means that they can be broken down in the compost heap or in industrial composting facilities.
- Biodegradation : Within a few weeks to months, the linen fibers break down into their basic components without leaving behind any harmful residues.
- Nutrient-rich soil: When composted, the fibers help enrich the soil with organic material, which in turn benefits plant growth.
Important: To ensure complete composting, the fabric should not contain any synthetic additives such as polyester or chemical dyes. Kanela's linen bedding is free of such additives, making it ideal for composting.
Recycling of production residues
Even during the manufacturing process, care is taken to minimize waste and use the flax plant as comprehensively as possible:
1. Shives: The woody residues of the flax plant that accrue during the breaking and swinging process are used in other industries. They are used as, for example:
-
- Animal litter Due to its absorbency and naturalness.
- Insulating material In sustainable construction projects, the shives are used as ecological insulating material.
2. Short fibers: Fibers that are not suitable for the production of linen fabrics can be used in paper production or for yarn blends.
3. Seeds: The seeds of the flax plant are processed into linseed or linseed oil, which are highly valued in the food and cosmetics industries.
Upcycling and recycling of linen fabrics
Old linen fabrics or production leftovers do not necessarily have to be thrown away. They can be used in many different ways:
- Upcycling: Worn linen can be reworked into new products such as kitchen towels, bags or cleaning cloths.
- Recycling: There are also approaches in the textile industry to recycle old linen fabrics and prepare the fibers for new yarn or fabric production
A closed circuit
Linen is not only sustainable in its production, but also a real role model in terms of disposal and reuse. From the complete utilization of the flax plant to the biodegradability and the versatile uses of the residual materials - linen supports a closed production cycle that protects the environment.
By choosing a linen product from kanela, you are choosing a material that still creates added value even at the end of its lifespan – for you, for nature and for a sustainable future.
Linen: The perfect symbiosis of science and nature
After examining the importance of an optimal sleeping environment and the complex steps involved in linen production, it becomes clear why this material is such an exceptional choice. Linen combines scientifically proven benefits for sleep with a sustainable, well-thought-out manufacturing process. Its properties make it not only an ecological but also a functional and stylish solution for restful nights:
Temperature regulation:
Linen bedding has a remarkable ability to regulate body temperature. Studies show that linen is the ideal choice for all seasons: in summer it is cooling and wicks away moisture, while in winter it stays warm and cozy. These thermoregulatory properties help the body maintain its optimal temperature during the night. Linen helps to increase sleeping comfort through its temperature regulation and moisture absorption.
Breathability and moisture management
Linen can absorb up to 20% of its own weight in moisture without feeling damp. The fibers consist mainly of cellulose, a substance that has a natural affinity for water. These hydrophilic molecules bind moisture and efficiently wick it away. In addition, the structure of the flax fibers is hollow and contains fine capillaries that ensure that moisture is quickly absorbed and evenly distributed.
This ability to absorb moisture is supported by rapid evaporation, as the open structure of the fibers promotes air circulation and the moisture is quickly released again. This means that linen provides a dry, comfortable sleeping environment that keeps the body cool and reduces the risk of skin irritation or overheating - a great advantage for people who tend to sweat at night.
The ability to manage moisture is often highlighted in research. A study by The Sleep Council confirms: “A dry sleep environment helps improve sleep quality and reduces the risk of nighttime skin irritation.
Natural and sustainable
Linen is not only functional but also environmentally friendly. The flax plant requires less water and pesticides to grow compared to other crops such as cotton. Linen production is a more environmentally friendly alternative as it uses fewer water resources and produces fewer CO2 emissions.
At kanela, we focus on sustainability and offer linen bed linen that meets the highest quality standards and is kind to the planet. We only use European long-fiber linen, which is known for its exceptional strength and softness. We guarantee the highest quality standards.
Durability and ease of care
Linen gets softer with each wash without losing quality. Unlike synthetic materials, it retains its shape and is resistant to wear and tear. Linen is also naturally antibacterial and dirt-repellent, making it a particularly hygienic choice for your sleeping area.
A study by The Journal of Textiles shows that linen's natural properties mean it has a lower accumulation of bacteria and dirt, contributing to a better sleeping environment.
In addition, our linen is pre-washed using the latest techniques to preserve its natural texture. On the contrary, with each wash it becomes softer without losing its shape.
The result is a perfect balance of luxurious softness and robust durability. Our linen products are made to last for generations.

The Key to Health and Well-Being
We spend a third of our lives in bed - that's about 8 hours a night. This time is crucial for our physical and mental regeneration. When you consider how much influence sleep has on our health, it quickly becomes clear why it is important to prioritize the quality of our sleep.
Scientific studies show that sleep is crucial not only for recovery but also for our long-term health. According to the National Sleep Foundation, poor sleep quality not only affects our mood and performance, but also our immune system, our cognitive functions and even our life expectancy.
A study by the Sleep Research Society found that consistent sleep quality significantly reduces the risk of chronic diseases such as heart disease and diabetes.
The first step to better sleep begins with choosing the right sleeping environment.
The bedding we sleep in has a significant impact on the quality of our sleep. This is where linen comes in - a material that is not only considered a luxury for the senses, but also a smart choice for our health.
Linen bedding is particularly known for supporting natural temperature regulation. During the night, our body goes through various sleep phases, as described above, including the restorative deep sleep and REM phases. These phases are crucial for physical regeneration and mental clarity. A stable temperature balance during sleep promotes these transitions and ensures that the body gets the best possible rest.
Linen has the remarkable ability to regulate body temperature, staying cool in summer and comfortably warm in winter.

Linen bedding supports this important function by efficiently wicking away moisture while creating an ideal balance between breathability and heat retention. This means that sweat is quickly removed from the body, which is particularly beneficial for people who sweat at night or suffer from hot flushes. This moisture-regulating property contributes to a comfortable sleeping environment and reduces the risk of nighttime discomfort and skin irritation.
In addition, linen is an extremely durable and easy-care material. It gets softer over time without losing quality. Studies show that linen is more durable than synthetic fabrics. It retains its shape even after numerous washes, making linen a worthwhile investment. This not only means less consumption of resources, but also a more sustainable decision for your everyday life.
