Deadly Consequences
Matthew Walker explains how insufficient sleep is linked to every disease that is killing us in the developed world, including cancer and Alzheimer's disease. The number of people who can survive on five hours of sleep or less without showing any impairment is zero, and even those who think they can survive on insufficient sleep are at risk of chronic and acute health problems. The link between a lack of sleep and cancer is so strong that the World Health Organization has classified any form of nighttime shift work as a probable carcinogen.In this clip

Can you provide accurate information about how sleep is linked with longevity, including stats and studies showing these stats, and then a detailed scientific explanation of exactly how this happens by increasing the risk of diseases? Here are my bullet points that need science detail and accurate stats: Risk of poor sleep: Sleeping less than 7 hours a night raises your risk of early death by 24%. Cancer link: Lack of quality sleep reduces natural killer (NK) cell activity by 70%, increasing cancer risk. Heart health: Poor sleep raises cardiovascular risks, affecting blood pressure and arterial health. Cognitive impact: Sleep disruption impairs the glymphatic system, preventing brain detoxification and increasing dementia risk. Modern life effects: Even with 7+ hours, stress and modern lifestyle factors can ruin sleep quality—quality matters just as much as quantity.
Regularly getting less than six hours of sleep can increase your risk of serious health problems like cancer, heart disease, obesity, and Alzheimer's disease. Insufficient sleep weakens your immune system and causes hormonal imbalances that can lead to weight gain and diabetes. It also promotes inflammation and stress in your body, which are linked to chronic diseases. Therefore, it's important to get enough sleep to stay healthy.
Is it correct to say, "Regularly getting less than six hours of sleep increases your risk for cancer, heart, and brain diseases" in the context of the episode 126: Matthew Walker | Unlocking the Power of Sleep and Dreams and the clip The Importance of Sleep?
