New classification of insomnia

Insomnia affects tens of millions of people across the world, but experts are still debating its definition. In this remarkable article published in The Lancet Psychiatry, the team of Pr. Van Somereun describe their new classification of insomnia into 5 sub-categories that resulted from a questionnaire of over 500 questions and diverse biological data.

Here’s a quick sum-up of the study:

 A Blood Test for the Body’s Clock

This fascinating article published in Scientific American details the work of 3 scientific teams looking to determine the internal time of our biological clock by using blood samples. This discovery could improve the effectiveness of certain treatments that are sensitive to biological rhythm.

Using Sound to Strengthen Deep Sleep

Pr. Phyllis Zee at Northwestern University is a specialist in the acoustic enhancement of deep sleep. Along with her team, Pr. Zee has shown this acoustic enhancement strengthens the autonomic activity of the nervous system, which is the principal regulatory system of the heart. These results are promising and will now be tested on people suffering from cardiovascular problems.
