Bad sleep dramatically alters body health

RATE THIS! +39

A run of poor sleep can have a potentially profound effect on the internal workings of the human body, say UK researchers. The activity of hundreds of genes was altered when people's sleep was cut to less than six hours a day for a week. Writing in the journal PNAS, the researchers said the results helped explain how poor sleep damaged health.

 
Heart disease, diabetes, obesity and poor brain function have all been linked to substandard sleep. What missing hours in bed actually does to alter health, however, is unknown. So researchers at the University of Surrey analysed the blood of 26 people after they had had plenty of sleep, up to 10 hours each night for a week, and compared the results with samples after a week of fewer than six hours a night.
 
More than 700 genes were altered by the shift. Each contains the instructions for building a protein, so those that became more active produced more proteins - changing the chemistry of the body.

This is yet another line of evidence that mind and body are tightly interconnected. Sleep is an important function and there is lot of evidence that it has to be taken seriously to avoid big health problems
