Interesting Fact - Sleep
Research into sleeping patterns carried out at the University of Surrey, have shown that working night shifts sends the human body into chaos, and could cause lasting damage to health. (Working irregular shifts has a similar effect to severe jet lag or repeatedly missing sleep. Even more worryingly it has a damaging effect at the level of our DNA, with hundreds of genes, whose activity should rise and fall on a daily basis, losing their rhythm, and other genes developing abnormal cycles of their own. So basically not getting enough sleep is bad for you, and sleeping at the wrong time is bad for you too. We can't win!) Source
