RESEARCH BASED, SCIENTIFICALLY PROVEN

"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. Dagsmejan’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)

Very comfortable to wear

I love the material of the Nattwarm series and use the mask even in warm temperatures without any problems. It darkens sufficiently for me to be able to fall asleep in the light.
