The sleep benefits

Overheating at night? These cooling sleep shorts offe unrivalled breatability so that that excess heat never builds up.
• 14x more breathable than cotton
• Lightweight
• Cooling design
“Even a small rise in body temperature during the night can have a major impact on our sleep. When we overheat, the body struggles to enter and maintain deep sleep — heart rate and stress levels increase, we wake more often, and true recovery becomes impossible. Dagsmejan’s Stay Cool collection is designed to counteract exactly that. Its intelligent cooling and moisture-management technology helps the body release excess heat and maintain the optimal temperature for restorative, high-quality sleep — night after night.”
— Dr. med. Lutz Graumann, Specialist in Sports Medicine, Nutrition & Regenerative Medicine.

"Thermoregulation is key for good sleep. To fall asleep and enjoy a deep, restorative sleep we need our body temperature to drop. I recommend Dagsmejan; their pajamas help us to cool down or warm up depending on our needs to sleep deeper for longer."
