New research shows that many people are not sleeping enough and that this is having serious impact on health. Professor Matthew Walker from Center for Human Sleep Science at University of California warned that "catastrophic sleep-misfortune plague" was putting people in danger of ill health. He said continued lack of sleep was putting people at risk from large number of possibly fatal diseases. Professor Walker said people need eight hours sleep night to stay healthy. He continued that people who don't sleep enough will have shorter life. Walker said effect of not sleeping enough negatively impacts every single aspect of our health and every part of our body.
Professor Walker warned that lack of sleep is linked to debilitating diseases such as Alzheimer's, cancer, heart disease, obesity and diabetes. He warned that we are in dangerous situation whereby we do not fully understand very serious, "catastrophic" consequences of not getting eight hours night. He gave several reasons why we are sleeping less. He said: "First, we electrified night. Light is profound degrader of our sleep." He also blamed longer working hours and longer commuting times, desire to be with friends more rather than sleep, mobile devices, and increased availability of alcohol and caffeine. He also blamed anxiety and said: "We're lonelier, more depressed society."
