The research is published in Diabetologia, the journal of the European Association for the Study of Diabetes (EASD), and is by Elisabeth Thiering and Joachim Heinrich, Helmholtz Zentrum München, Neuherberg, Germany, and colleagues. http://medicalxpress.com/news/2013-05-air-pollution-insulin-resistance-children.html Diabetes Thu, 09 May 2013 18:00:02 EST news287316347 (Medical Xpress)—Exposure to noise, for example from road traffic, may adversely affect the cardiovascular system. Until now, underlying mechanisms linking noise to elevated cardiovascular risk have rarely been explored in epidemiological studies. Scientists of Helmholtz Zentrum München have now shown that exposure to noise during everyday life influences heart rate variability, i.e. the ability of the heart to adjust the rate at which it beats to acute events. The results were published in the journal Environmental Health Perspectives. http://medicalxpress.com/news/2013-05-exposure-everyday-noise-heart-variability.html Health Thu, 02 May 2013 07:20:01 EST news286695411 Most often, people associate circadian rhythms with the symptoms of jet lag that occur after crossing several time zones.
