We are designed and adapted to work, eat, and move during the day, and to sleep, rejuvenate, and repair at night. We function in perfect harmony with the movements of the planet; even our hormone production is coordinated with the rising and setting of the sun, in a complex system that has evolved over millions of years. All of this occurs, quite simply, to increase the chances of our survival. It’s only relatively recently, however, that we’ve really started to understand the relationship between the circadian rhythm and our well being, and that’s why the news that the Nobel Prize in medicine has been awarded to three scientists who discovered the gene responsible for ensuring for controlling circadian rhythm is hugely significant.
