"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."

Eye mask

This is a good eye mask which is very comfortable to wear and the material feels lovely and soft. My head doesn’t feel hot when wearing it. I’ve only given it 4 stars as it’s a little large on me

NATTCOOL SLEEP PANTS

I was a little dubious that they would be cool for sleeping when they arrived. The material was unbelievably silky, and they felt so lightweight. But they were full coverage from waist to ankle—seeming about the same as my Dagsmejan BALANCE SLEEP PANTS. But, Wow— there was a cooling sensation upon slipping them on! That night, paired with a short sleeved marching NATTCOOL top, I actually slept much more deeply than usual and did NOT wake up moist from sweat....In fact, even in wakeful moments at night when I know the body tends towards higher temperatures, I remained, cool, comfortable and relaxed. NATTCOOL SLEEP PANTS are a blessing!!!!
