Research performed by the Australian Wool Innovation organization proves that wool “delivers 25% more deep regenerative sleep”. If you are surrounded by higher humidity your sleep can be restless. Wool has greater thermoregulatory properties. It not only is a good insulator but wool fibres absorb moisture and wick it away into the atmosphere to reduce humidity in your sleep environment.
That same property in wool can also actually lower your heart rate as you sleep and lead to a more relaxed sleep. That has not only short term benefit, but also long term heart benefits.
Wool is naturally hygienic. Wool inhibits the growth of bacteria, fungi and dust mites. Wool is also a “natural fire barrier”. Fire fighters’ protective uniforms were originally made from wool. So if mattresses are properly insulated with wool, there is no need for chemical fire retardants. For these reasons, wool is the natural choice for those that suffer with asthma or allergies.
Studies have shown that babies sleeping in wool are less stressed when sleeping, and have less clammy skins which leads to fewer rashes and bed sores. They also have better appetites and underweight newborns sleeping with wool bedding gain weight.
So sheep can really help you sleep better.
