Looking for relief from hot flashes or just want a better night’s sleep? Studies show that pure merino wool pajamas can keep you cooler and allow you to fall asleep faster than cotton or polyester fabrics. 

Sleep can be particularly problematic for women in menopause or perimenopause, and as they age. Hot flashes, also known as night sweats, can negatively impact the quality of sleep and leave sufferers exhausted. But what can you do about it? Research shows that merino wool sleepwear is a huge help toward getting better sleep.

Wearing 100% merino wool, the fabric found in every piece of Chill Angel sleepwear and clothing, helped participants get to sleep in about half the time compared to those wearing cotton or polyester,  according to a recent study  ​​https://pmc.ncbi.nlm.nih.gov/articles/PMC6716586/ by scientists at the University of Sydney.

Poor sleepers were  able to sleep more soundly with less wakefulness in the pure merino sleepwear, and they were in the deep sleep (REM) stage longer. The study conclusion states that “statistically significant benefits for wool sleepwear were observed on average for all participants”.

Why does wearing wool help women (and men) to cool down?

  • A thin layer of wool, such as the ultrafine merino used at Chill Angel, is breathable, wicks sweat, and keeps wearers more comfortable in any temperature.
  • Wool pulls dampness away from skin before it becomes sweat. Merino wool can absorb over 30 percent of its weight before it will feel damp. This keeps your skin dryer and battles sweat before it can form.
  • The moisture absorption properties of merino work the other way around, too, trapping humidity in the air before it can reach your body.
  • The curly fibers of merino wool allow moisture to pass through, keeping wearers more comfy no matter what the outside temperature.
Chill Angel merino is also naturally flame resistant, igniting at a much higher temperature than other fibers and smoldering, rather than bursting  into flame or melting. In fact, studies  https://www.wool.com/news-events/news/wool-protects-skin-from-flames/ show wool clothing is preferred for military and firefighters.
