    One night without sleep can make you feeling tired the whole day and yawning will probably annoy you and the people around. How about two nights of no sleeping or three? It will surely make you cranky and restless. But just a week of not enough sleep can radically change the activity of human genes.

    According to a new study published by the Proceedings of the National Academy of Sciences, just one week of abnormal, insufficient sleep is enough to dramatically alter the activity of human genes.

    University of Surrey in England conducted a survey and the experiment discovered that lack of sleep, at least less than six hours a night will affect the activity of over 700 of our genes.

    The genes that will be affected are associated with controlling response to stress, immunity, and inflammation.

    Furthermore, the research demonstrates that insufficient sleep reduces the number of genes that normally peak and fall in expression during a 24-hour period from 1,855 to 1,481.

    After a week of pitiable sleep the number of genes influenced by sleep deprivation is seven times greater.

    Obesity, cognitive impairment, heart disease are just few of the complications of not having enough sleep.

    According to the Centers for Disease Control and Prevention, USA, sleep deprivation and sleep disorders affect from 50 to 70 million people in America thus making sleep disorders very common. But until recently, scientists were unaware how gene expression patterns were modified by poor sleep. Th...
