Have you ever felt like you couldn't sleep unless you were covered up, even though it might be the hottest days of the year? Don't worry, you're not alone!
To explain why it happens, let's take a look at the findings of psychology and science about this "phenomenon."
Sleeping covered isn't just a matter of habit or comfort. According to experts, the feeling of being covered activates the parasympathetic nervous system, which promotes relaxation and reduces alertness in our body.
In fact, research from the University of California's Department of Anesthesiology, published in 2011, found that the pressure exerted by blankets can help relieve chronic pain and improve sleep quality.
Additionally, researchers from Flinders and Adelaide Universities have found that blankets and quilts in general can reduce anxiety and depression in adults, providing a sense of calm and relaxation.
However, there are exceptions. Although blankets are often used for children with ADHD or autism spectrum disorder, there is not enough scientific data to support their effectiveness in all cases. In some situations, they may increase stress rather than reduce it.
So, the next time you wonder why you can't part with your blanket, remember that it could be the 'key' to a more restful, quality sleep!
