Most of us can feel the impact of a sleepless night the next morning. However, after a few days of sleeplessness, there are major disruptions in the body's genes. According to new research, lack of sleep leads to increased risk of illnesses linked to immunity and stress. The study compared bloodwork of people who had more than 10 hours of sleep in one night to those who had less than six hours of sleep a night for one week and the results were vastly different.
"There was quite a dramatic change in activity in many different kinds of genes," the lead researcher told BBC. "Clearly sleep is critical to rebuilding the body and maintaining a functional state, all kinds of damage appears to occur-hinting at what may lead to ill health. If we can't actually replenish and replace new cells, then that's going to lead to degenerative diseases."
