Regular poor sleep puts you at risk of serious medical conditions, including obesity, heart disease and diabetes – and it shortens your life expectancy.
It is estimated that 50 to 70 million Americans chronically suffer from a disorder of sleep and wakefulness, hindering daily functioning and adversely affecting health and longevity. There around 90 distinct sleep disorders; most are marked by one of these symptoms: excessive daytime sleepiness, difficulty initiating or maintaining sleep, and abnormal events occurring during sleep. The cumulative long-term effects of sleep loss and sleep disorders have been associated with a wide range of deleterious health consequences including an increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke.
In the long term chronic poor sleep can increase the risk of ill health including depression and anxiety, weight gain, high blood pressure, type 2 diabetes, immune system suppression, stroke and cardiovascular disease. [Refer Source: https://www.ncbi.nlm.nih.gov/books/NBK19961/]
