Sleep is one of the most important things that you can do for your body in order to keep it healthy. It is very interesting though, how little we understand sleep and dreaming and why it is so essential. New studies are showing however what lack of sleep or too much sleep can do to the body and this is another step on the way to demystifying sleep.
People who sleep fewer than 6 hours or more than 10 hours per night suffer from low-grade inflammation more often than people who sleep 7-8 hours per night. Earlier studies have found a relation between reduced sleep and low-grade inflammation, according to one of the study researchers. Furthermore, low-grade inflammation occurs in overweight, depression and diabetes. This new study is the first to analyze the association between sleep duration and serum micronutrient concentrations in a large sample, and it found a link between high serum copper concentration and long sleep duration.
