Studies show that people sleeping with wool bedding have a lower heart rate, less sleep disturbance, and increased duration of beneficial REM sleep. ... In the winter, wool warms without overheating or causing clamminess. Conversely, in spring and summer, it helps to keep you cool by wicking moisture away from your skin.
What are the benefits of wool?
The primary characteristic of wool is that it is an excellent insulator. A woolen sweater will keep you cozy and warm by trapping air between its fibers. It also allows moisture (perspiration) from your body to evaporate (wick) through the fabric. This helps keep your skin dry and comfortable.
It keeps you cool
Wool is a natural fibre and unlike its synthetic counterparts, it is extremely breathable, helping you to keep cool and comfortable. Synthetic bedding such as polyester and other natural alternatives like goose down and feather beddings are heavy insulators, but lack the ability to control temperature. They actually trap hot air – meaning under the covers can become very hot, making you restless and uncomfortable, reducing the quality of your sleep. Wool, on the other hand, has the ability to regulate heat and keep your body temperature at its optimum level, in turn increasing your sleep quality by up to 25%.
It keeps you warm
As well as keeping you cool when you need it, wool bedding can keep you warm. Wool is a natural insulator, so unlike its synthetic rivals that trap hot air and moisture, it will keep your body at the optimum sleep temperature without making you overheat. Wool duvets, pillows and beds breathe and dissipate the natural humidity that your body produces, keeping you warm and comfortable without overheating.
It stops you getting sweaty
Wool bedding absorbs moisture and draws it away from your body a lot more effectively than bedding made from other materials. Down absorbs just 5% of its weight in water, while cotton bedding absorbs 10%.This is the reason you can often wake up sweaty and uncomfortable. By comparison, wool duvets are capable of absorbing 33% of their own weight in water, meaning you’re much less likely to wake up clammy under a moist, humid duvet.
Wool defeats dust mites
Wool offers a dry environment to dust mites – the exact opposite of what they like. Dust mites thrive in warm, moist environments and will happily make their home in synthetic and heavily insulating materials like cotton and feather bedding. The ability to regulate temperature and release moisture – that other materials lack – is the reason that wool does such a great job at repelling dust mites.
It defends against fungal spores
Wool’s ability to regulate moisture is also the reason it is so effective at repelling fungal spores. Polyester, down and feather bedding trap heat and create a moist, humid environment, ideal for the growth of fungal spores. These spores are a common cause of night-time allergies, causing sneezing, coughing and dry, itchy eyes. Wool bedding ensures that moisture is regulated and prevents the development of fungal spores in your bed.
Choose wool for better quality sleep With its unique combination of heat and moisture regulation and hypoallergenic qualities, wool helps you to get more deep, regenerative sleep. By regulating temperature and minimising sleep disturbances, wool allows you to stay in stage 4 sleep (also known as “deep sleep”) for longer, helping you to wake feeling refreshed and ready to go in the morning.
