Prof. Michael Gradisar

"There are companies that rush their products to market - and then there's Dagsmejan. I was immediately impressed that they consulted scientific experts in textiles, temperature regulation and sleep before the first stitch was sewn. My PhD investigated links between thermoregulation, sleep and insomnia, and I saw straight away that Dagsmejan sleepwear could balance one's environment with one's body. And I never expected their sleepwear to be so damn comfortable! Sometimes when I'm working from home - I just keep wearing them. You should too." 

— Professor Michael Gradisar, Sleep Researcher, Clinical Sleep Psychologist, CEO of WINK Sleep Online



"Sleep is vital. By understanding the factors that affect our sleep and by changing a few habits we can have a big impact on our sleep quality and wellbeing. Sleepwear and bedding that help to manage temperature and sweat during the night can support the body's natural thermo-regulation."

—Professor Torbjörn Åkersted, Director of Stress Research Institute, Division Manager for Biological Psychology and Treatment research, Stockholm University


"Thermoregulation is key for a good night's sleep. To fall asleep and to enjoy a deep, restorative sleep we need for our core body temperature to drop, but if we get too cold we will shiver and our sleep quality suffers. That is why I recommend sleepwear by Dagsmejan; they help us to cool down or warm up depending on our needs so that we can sleep deeper for longer."

“A good night's sleep is a decisive factor for our performance and especially for calling on top performance when it counts. Together with the Swiss Federal Institute for Materials Science & Technology (EMPA), the young Swiss company Dagsmejan has developed a new type of functional sleepwear that is ideally suited to the physiological needs of the sleeping body. Personally I can highly recommend these products.”

"Many of us know it: cold feet in the evening that prevent you from falling asleep, or a tropical summer night that comes with restless sleep. The fact that body temperature and sleep are inseparably linked, is also evident from a scientific perspective. The right temperature at the right time is essential for good sleep. Dagmejan’s sleepwear can support the nightly changes in body temperature and thereby naturally improve sleep."

— Dr. Christine Blume, sleep researcher at University Hospital Basel (Switzerland)


Dr. Roy Raymann

“Sleep, temperature and comfort are functionally linked. For a good night you need feel comfortable warm, not cold, nor hot. That is the oversimplified outcome of the years of research executed during my years at the prestigious Netherlands Institute of Neurosciences. Dagsmejan Sleepwear implements two basic principle for a good night of sleep in one product: It helps you maintain the right temperature through the night and it fabric feels so comfortable that it is a true pleasure and reward to wear.”

— Dr.  Roy Raymann, Sleep Neuroscientist and Ambulatory (Sleep) Technology expert, holding a PhD in Sleep & Thermoregulation, Founder of SleepCzar

“Optimal sleep is essential for you, for athletes, for everyone to recover from the mental and physical demands of daily life. Yet many of us aren’t getting enough of it and unintentionally, we often tend to compromise the quality. If you aim to create the best foundation and ensure your balance and ability to perform, stay healthy and happy, you need to understand your 24-hour perspective and support your body in the right way. Dagsmejan is a valid and excellent supporting tool to do exactly that ”. 

— Anna West, BScN/Founder of Sleep2perform, a high-performance consultancy specialized in sleep and recovery working with leading sports teams and businesses across Europe



Sleep is essential for our health and wellbeing. For women sleep quality and sleep challenges varies throughout her life. Hormonal changes during menstruation, pregnancy and nursing as well as menopause can make sleeping well difficult. In part because of temperature fluctuations and night sweats which lower our sleep quality. By staying in the ideal climatic comfort zone we can sleep deeper and longer. Dagsmejan’s temperature regulating sleepwear can be a great aid to keep the best temperature for sleep.”

Innovation—scientifically proven

Thanks to our extensive research and testing carried out with leading partners in the fields of smart textiles and sleep we have been able to ensure that Dagsmejan sleepwear truly delivers on its promise. The optimal fibre and knitting techniques we employ were selected after thorough laboratory testing to ensure that we could deliver superior temperature regulation and moisture management, as well as a super soft touch. The sleepwear’s ergonomic comfort was also tested extensively in consumer fit trials. 

Dagsmejan is involved in an ongoing interdisciplinary research project together with EMPA, a world-renowned Swiss research institute for innovation in materials science and technology and the Lucerne University of Applied Science and Arts (HSLU), one of Switzerland's leading providers of degree programmes in art and design.
