The cumulative effects of chronic sleep deprivation could be shortening our lives. There is evidence that potentially killer diseases are more likely to occur if we get too little sleep over a prolonged period. One reason why we may not be getting enough shut-eye is excessive noise. Mathias Basneris Associate Professor of Sleep and Chronobiology in Psychiatry at the University of Pennsylvania Perelman School of Medicine and President of the International Commission of Biological Effects of Noise. For the past two decades he has been studying the effects of noise on sleep. It could be the sound of airplanes overhead, the rattling of a heating system or noisy air conditioning that keeps us awake, but research suggests there is a significant connection between noise, sleep, and recuperation. In this LLAMA podcast interview, recorded at TEDMED 2018, Dr Basner explains the basis for his research and the lifestyle lessons he’s learned through the study of environmental stresses and society’s big problem of sleep deprivation.
