Sleep Better in Merino

Wearing wool sleepwear improves sleep quality

The latest study conducted by researchers at The University of Sydney has found adults wearing wool  sleepwear fell asleep in just 12 minutes compared with 22 and 27 minutes for those wearing polyester and cotton.

“Wool helps regulate your body temperature, keeping you in what is known as 'the thermal comfort zone' for longer,” explains Associate Professor Chin Moi Chow from The University of Sydney. “You therefore not only fall asleep quicker, but also have deeper, less fragmented sleep.”

The study found these benefits were most relevant to older and poorer sleepers.

Benefits of Merino Wool for Sleep

1. Natural Temperature Regulation
   Merino wool is renowned for its ability to keep you warm when it’s cold and cool when it’s hot. This is due to the fiber's natural structure, which traps air to provide insulation while also allowing moisture to escape. Unlike synthetic fabrics that can trap heat and cause sweating, merino wool works with your body to maintain an optimal sleeping temperature. This makes it ideal for year-round comfort.

2. Moisture-Wicking and Breathability
   Night sweats or feeling clammy in bed? Merino wool can absorb up to 30% of its weight in moisture without feeling wet, helping to keep your skin dry throughout the night. It also allows for excellent airflow, reducing the risk of overheating and ensuring a fresher sleeping experience.

3. Soft and Gentle on Skin
   Merino wool fibers are incredibly fine and soft, making them gentle on sensitive skin. Unlike coarser wools, merino won’t itch or irritate, ensuring a luxurious, soothing feel against your body as you sleep. Merino is naturally elastic so moves with your body so you won't get "caught" up in your night attire!

4. Hypoallergenic and Odour-Resistant
   Merino wool is naturally hypoallergenic, making it a great choice for people with allergies or sensitive skin. Additionally, its antimicrobial properties resist odours, so your sleepwear stays fresher for longer—perfect for extended wear on cold winter nights or travel.

5. Durable and Sustainable
   Merino wool is not only long-lasting but also a sustainable choice. Merino Country products are made from 100% Australian Merino wool, which is ethically sourced and biodegradable. By choosing merino, you’re making an eco-friendly choice without sacrificing quality or comfort.
