People who struggle to sleep should consider switching to woolen bedding, new research suggests. Wool fibers absorb moisture, including sweat, making it easier for the body to regulate its temperature. This leads to a more comfortable night's sleep.
On average, people sweat a liter of water every night and this cannot be absorbed by the synthetic materials often used to make bedding. As a result, people using these bedding materials are more likely to find themselves uncomfortably hot.
Researchers at the University of Sydney asked eight volunteers to sleep in woolen bedding, cotton bedding and synthetic bedding at three different temperatures. They discovered that, particularly when the bedroom was warmer, people slept for longer and more deeply when using woolen bedding.
