Wool promotes a better night’s sleep


Wool sleepwear and bedding have been shown to improve sleep quality. 


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.

The effect of sleepwear and bedding on sleep at ambient temperatures

An earlier study, also conducted by The University of Sydney researched the effects of sleepwear fibre type and bedding on sleep at ambient temperatures of 17°C and 22°C.

Seventeen healthy young adults underwent 9 nights of polysomnography testing and found the time it took to fall asleep was significantly shortened when sleeping in superfine Merino wool, with trends of increased total sleep time and sleep efficiency compared to cotton sleepwear.

The group fell asleep faster on average when wearing Merino wool, taking 11 minutes whereas it took 15 minutes on average in cotton,. The research paper was published in the journal Nature and Science of Sleep (2016).
