Case sharing | How DYKON sleep laboratory calculates optimal sleep comfort

Sleep is one of the biggest topics in the world. The quality of sleep will directly affect our health and quality of life. Good sleep not only means enjoying life, but also effectively promotes physical health. 

Walking into your bedroom, turning off the lights and falling asleep immediately does not equate to a good night’s sleep. Deep sleep is closely related to the environment, mentality, and bedding. For example, the factors that affect sleep comfort include: temperature, humidity, light, support, and the materials of sheets and quilts, including breathability and cleanliness.
Bedding such as mattresses and quilts are items that are in direct contact with the body. Their material, hardness, breathability, and comfort directly affect the tension of the muscles throughout the body, thereby affecting the quality of sleep. Research shows that suitable bedding can improve sleep quality by 20% every night and help people fall asleep quickly. Therefore, adjusting bedding to improve sleep comfort is undoubtedly a shortcut.

Better sleep, better life

DYKON is a leading Nordic manufacturer of duvets and pillows. It has been producing high-quality lifestyle products for more than 70 years and has gained unique experience in down and feather processing during this period. Years of accumulated experience have made them the largest down processing company in Northern Europe.

Our bedding manufacturer client DYKON has developed its own sleep laboratory in collaboration with the Technical University of Denmark to study which types of duvets and pillows provide the best sleeping comfort in different specific climates. The sleep laboratory’s most important goal is to ensure that people get a good night’s sleep, with the goal of finding the secret to optimal sleep comfort.
Everyone has different needs and preferences when it comes to sleep. Some people like to open windows, others prefer a warm room. Some lie on their backs, some on their sides. Some find comfort under a heavy duvet, others in the light. Through DYKON’s research, it was found that a sense of security and inner peace are the most important parameters for good sleep, sometimes even more important than obtaining optimal physical comfort.

Study bedding materials of different materials to obtain the best sleep comfort in different climate conditions
Danish PT Teknik body-warming dummy-  an indispensable helper for thermal comfort
The sleep laboratory consists of multiple monitoring items, including: controllable room temperature and air humidity; different parameter detection programs, and the use of software to display 3D data visualization. The most important and key equipment is also used in the sleep laboratory, which is the PT Teknik warm body dummy to measure human thermal comfort. The PT Teknik warm-body dummy used in the DYKON sleep laboratory is a heated human body model. The body is divided into 28 areas. Temperature sensors are distributed all over the body. There are sensors on every surface of the model to achieve comprehensive data collection. . In addition, the thermal radiation of the human body model is 95% the same as that of a real person, and it can absorb the same proportion of long and short radiant heat as the human body . 

Inside the laboratory, the mannequin is equipped with a bed to sleep on. The bedrooms have climate controlled systems. The room temperature can be set between 10 and 40 degrees Celsius, and the humidity between 0% and 90%. In this way, it is possible to simulate almost any bedroom environment in the world and find the right ingredients for a duvet in a specific climate.
In addition to warm-body dummies and environment-controlled bedrooms, DYKON’s sleep laboratory also contains a large amount of data, which is imported into APP applications and used with virtual reality glasses to present more intuitive results. It can also be used on tablets and smart phones. Seen on mobile phone.
Digital Twin Digital Twin – Change is under your control

Based on the results obtained by DYKON during their research, they created a database to show how materials, down and feather qualities interact with each other and how a down comforter “performs” under specific conditions. The sleep laboratory can therefore develop the perfect duvet for its customers and even calculate optimal sleeping comfort.

The data output by the warm-body dummy can be integrated into the CFD virtual simulation software through the Digital Twin, including all environmental and personal parameters for thermal comfort analysis, creating a digital twin system for tripartite comparison of experimental data, simulation data and subjective evaluation. With the warm-body dummy, the data information obtained during the sleep laboratory test can be visualized in a 3D dynamic form.

Perform data visualizations to make it easy for customers to understand how the comfort of a heated dummy changes in a specific climate. Colorful temperature scales in the sleep lab show whether the body-warming dummy feels cold, comfortable or warm. When another duvet and climate are selected, the comfort level of the body-warming dummy will change according to the new combination, and the corresponding comfort level will be measured.

Conclusion
Sleep may also be called a kind of enjoyment, because it is the most effective and comfortable replenishment of physical strength when tired, and a comfortable sleeping environment is crucial. 

When people sleep, their physiological state is different from the waking state. The most obvious point is that metabolism is significantly slower than in the awake state, and according to research, the body’s temperature and hormone levels are also different at different times. Different from dressing in the awake state, mattresses and quilts are also insulated when sleeping. part of the layer.

Using PT Teknik body-warming dummies to test the thermal comfort performance of quilts, pillows and clothing can eliminate the need for traditional manual scoring systems and quickly digitally measure comfort differences in different environments, clothing and bedding combinations, helping Manufacturers develop rating products to provide an objective reference for comfort.

Danish PT Teknik thermal dummies do more than just help you test the thermal performance of clothes, bedding and other wearable garments. It can also be used to analyze thermal comfort and air quality in outdoor and indoor environments, vehicles, aircraft, etc. Welcome to contact us~
