"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." –dr Lutz Graumann, Phd & specialist in sports medicine, nutrition and chirotherapy
