Since humans are fundamentally diurnal creatures, staying awake at night can significantly disrupt all of the body’s internal biological clocks. These disruptions are far from harmless: over the long term, they can lead to a high incidence of various health problems, such as metabolic or cardiovascular problems or even certain types of cancer.
Imagine being able to easily get over all of the discomfort and problems of jet lag or night-shift work. Science is not quite there, but recent work by Marc Cuesta, Nicolas Cermakian and Diane B. Boivin from the Douglas Mental Health University Institute and McGill University has opened new therapeutic avenues for improving the synchronization of the body’s different biological clocks.
Physiological changes over the course of a day are regulated by a circadian system comprised of a central clock located deep within the centre of the brain and multiple clocks located in different parts of the body.
This study, which was published in The FASEB Journal (published by the Federation of American Societies for Experimental Biology), included 16 healthy volunteers who were studied in temporal isolation chambers. These results show, for the first time, that the peripheral biological clocks located in white blood cells can be synchronized through the…
