'Catastrophic' sleep is killing people, say scientists

Research shows that we are not sleeping enough and that is affecting our health. A sleep expert warned that a "catastrophic sleep-misfortune plague" is making us ill. He said a lack of sleep puts us at risk from deadly diseases. The expert said if we don't sleep eight hours a night, we will die earlier. He added that not sleeping enough affects every single part of our health and every part of our body.

The expert warned that a lack of sleep causes diseases like cancer, heart disease, obesity and diabetes. We do not understand the "catastrophic" consequences of not getting eight hours a night. He explained why we are sleeping less. He said we "electrified the night" and this hurts our sleep. He also blamed longer working hours, a desire to be with friends, mobile phones, alcohol and caffeine. He also blamed anxiety, loneliness and depression.
