Sleep easy with wool

Shepparton News - - ENTERTAINMENT -

Wear­ing wool­lies in bed may be a more ef­fec­tive in­som­nia rem­edy than count­ing sheep, Aus­tralian re­search sug­gests.

It sounds like a du­bi­ous yarn. But ex­perts say wool helps keep the body in the ‘‘ther­mal com­fort zone’’ most con­ducive to rest­ful sleep.

Sci­en­tists in Aus­tralia car­ried out two stud­ies of young and older sleep­ers to test the the­ory.

Stu­dents in their 20s in the first group nod­ded off four min­utes faster on av­er­age when wear­ing py­ja­mas made from Merino wool rather than cot­ton, tak­ing 11 min­utes in­stead of 15.

They also en­joyed an ex­tra seven min­utes more sleep per night.

The sec­ond study found that woollen PJs had an even big­ger im­pact on older adults aged 65 to 70.

They fell asleep af­ter 12 min­utes, com­pared with 22 and 27 min­utes for those wear­ing polyester or cot­ton re­spec­tively.

Re­searcher Dr Paul Swan, from the Univer­sity of Syd­ney, said: ‘‘Not so long ago sleep­ing un­der wool bed­ding was the norm, and sci­ence is now re­dis­cov­er­ing the ben­e­fits of sleep­ing in wool’’.
