Why is sleeping with wool so amazing? Here is some deeper information:
Deeper, Longer, Better
Recently, a three-year study conducted at the University of Sydney showed that wool sleepwear promoted faster sleep onset than cotton sleepwear. Differences in sleep quality also showed that a combination of wool sleepwear and bedding produced a deeper and longer sleep with participants waking less frequently. Participants slept in Merino wool or cotton pyjamas, and under duvets of either cotton, polyester, or wool at three different temperatures: cold (62.6°F), neutral (71.6°F) and hot (84.2°F). The difference at high temperature was most marked. Generally, the lower temperature, 62.6°F, was found to be more conducive to sleep, and the findings highlight wool, next to skin, as an efficient insulator, researchers concluded. An earlier study showed that periods of immobile sleep increased when participants slept on a fleecy wool underblanket. Participants reported feeling better in the morning and having improved sleep quality. Similarly, when participants in another study slept on wool-on sheepskin underlays, they felt they had slept better. Researchers concluded that the wool pile diffused pressure points, provided better insulation to the sleeper, absorbed perspiration better than alternatives, and had a more reassuring handle.
Sleep, Little Baby
Weight gain in underweight newborns was 61% higher when they slept on a wool underlay instead of a cotton sheet, researchers have found. Jaundiced newborns sleeping on wool were more settled and cried less than those sleeping on cotton, other research revealed. In a study of Australian pre-school children on bedding fabrics and underlays, children who slept in any synthetic bedding in summer or winter were more likely to be reported as having a sleep problem, than those who slept in cotton or wool.
The Science of Sleeping with Wool
The Absorption Factor Scientists believe that wool improves sleep because it absorbs the sweat human bodies produce during the night, keeping skin dry and comfortable. In a leading German study at Holstein Institute, researchers found that wool blankets absorbed 50% more perspiration from sleepers than acrylic blankets. Consequently, when sleeping under wool blankets, the microclimate of the bed maintained a comfortable level of humidity, as evidenced by the sleepwear worn by participants: their pyjamas stayed drier. Wool’s moisture-absorbing properties derive from molecules in the fiber, which are able to create hydrogen bonds with water, immobilising the water and incorporating it into the fiber itself, with a small amount of heat released. Generally, wool can absorb up to 30% moisture to its own weight without feeling wet. Dynamic Thermal Capacities Wool garments have been reported to lower the relative humidity at the skin surface, and to delay the on-set of sweating which results in smaller changes in core temperature. “Buffering” is the term used for the probable explanation for these smaller changes to core body temperature. Buffering is a form of skin-clothing microclimate humidity control: As the rate of moisture evaporated from the skin increases, the relative humidity of the microclimate adjacent to the skin increases and the fibers respond by increasing moisture vapour content. This slows (or buffers) the rate of rise in humidity within the microclimate. As moisture levels decrease, the fibers give up some of their stored moisture, again slowing the rate of humidity change.
