"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."

“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 ”.

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”.
