We just seem to have forgotten about it in the last few decades, perhaps it’s time to take another look. After all wool is one of the worlds most breathable fibre and can absorb as much as 30% of its own weight in moisture before it transfers that moisture and heat, so What Is So Good About Wool and our British Wool Duvets?
We are often asked how is wool different to natural down, feathers or even polyester fibres? These are all very good insulators, they make the body warm and don't release heat as efficiently as wool. This is fine when you first get into bed, but then, during the night our body temperature should drop as we go into deep sleep. These insulators bring our body temperature up so we either fully wake up or toss and turn to cool off. Then we go to sleep again and repeat the process of getting hot. But this time it maybe our partner is too hot in the bed and so the great duvet war starts with us pulling and pushing off the duvet. This is not natural sleep and it prevents essential deep sleep which is necessary for cell regeneration and to help the body fight illness.
Wool is actually a regulator, not an insulator. It regulates your body temperature the same way as it does on the sheep. When it is too hot the wool passes the heat mainly in the form of moisture from the sheep's body out and when its cold its keeps the heat in. All wool products can do this but the more you process the wool, i.e. spin and weave it, then the less the wool can regulate heat. So we keep the wool in the same state as it is on the sheep. But the amazing thing about wool is that it will actually regulate the temperatures of two different people in the same bed.
Every fibre is covered with little cuticles, these are little hooks which allow us to spin and weave wool. It also makes wool felt. It's these hooks which dust mites hate. But just like a pine cone on a tree these cuticles open and close according to humidity and temperature. But they open and close much faster than pine cones. they react as soon as a body, be it sheep or human, comes into contact with it, thereby regulating the body temperature. But just like a pine cone which continues to open and close even when it's not on the tree, so the wool cuticles continue to open and close as long as you don't chemically treat it or bleach it. This will scorch the cuticles from the fibres thereby reducing the wools ability to regulate. It really becomes an insulator and only keeps you warm.
A Wool duvet is naturally hypoallergenic. It’s resistant to mould growth, and it inhibits dust mites which cause most of the allergic reactions.. A synthetic duvet and feather/down duvet retains your body moisture and you sweat into the duvet encouraging dust mites and mould. This also means they need regular washing. They can be home to more than 20,000 dust mites and their droppings, so a wool duvet is ideal if you suffer from asthma or allergies.
Did you know that to make wool fully machine washable and able to withstand a tumble dryer, every fibre has to be stripped with chlorine which diminishes its natural properties? You will be glad to know we don’t do this to our wool.
