Is it possible to reset our biological clocks?
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 has opened new therapeutic avenues for improving the synchronization of the body's different biological clocks.

Our biological clocks could refer to the moment when various activities in our lives take place. Sometimes, we may have good moments in life and want them to stay on forever. Some other times, we may have such bad moments that we never want to remember them in the future. Science has not been able to turn back the hands of time, or fast-forward it. Science would definitely never be able to do that. But a new study by researchers at the Douglas Mental Health University Institute and the McGill University have in a new study, opened new therapeutic avenues that could help improve the synchronization of the different moments of our life (the body’s different biological clocks). A circadian system made up of a central clock regulates the body’s physiological changes every now and then (within each day). The clock is located deep within the centre of the brain, but different other clocks are located in different parts of the body.
This study involved 16 healthy volunteers examined in temporal isolation chambers and the results show that the body’s peripheral biological clock located in white blood cells can be synchronized when glucocorticoid tablets are administered.
Humans are naturally diurnal beings, and staying awake late at night can considerably disrupt all of the body's internal biological clocks. These interruptions cannot be considered harmless because as time goes on, they can lead to a high prevalence of various health problems; problems like metabolic or cardiovascular issues or even certain types of cancer.
The researchers say they still don’t fully understand how these peripheral biological clocks adapt to night-shift work in humans. They however think that the clocks essentially depend on the central clock. This new study opens better avenues for the researchers to look at other options like the adjustment of biological clocks to the central clock in relation to how travelers cope with time differences in other countries.
