DEVELOPED WITH OUR EXPERTS

RESEARCH BASED, SCIENTIFICALLY PROVEN

"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. 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."

—Lutz Graumann, Phd & specialist in sports medicine, nutrition and chirotherapy
