Stay up

True song says Rhoma Irama, about staying up if there is no need for the ban. Scientists at Warwick University likens stayed up late as the middle of burning the candle at both ends. "Staying up all increase the risk of stroke and heart disease or triggering both diseases," the conclusions of their research.
They found that sleep deprivation is less than six hours increases the risk of death from heart disease by nearly 50 percent, and the risk of death from stroke by 15 percent.
Francesco Cappuccio, professor of cardiovascular medicine and epidemiology, and Dr. Michelle Miller, a professor of clinical sciences, making conclusions after examining 470 thousand people from eight countries, aged between seven to 25 years. Their research has been published in European Heart Journal.
Prof Cappuccio aware, staying often unavoidable in modern society, that all the required supplies. Office work, often brought home because they have to finish the next day.
"But in doing so, we significantly increase the risk of suffering a stroke or develop cardiovascular disease, which in turn will lead to a heart attack," he said.
If someone is sleeping less than six hours per night or have trouble sleeping, so he's 48 percent greater chance to experience death from heart disease and 15 percent greater chance of stroke.
"The tendency to stay up is actually a time bomb for our health so you need to act now to reduce the risk of this condition which threatens our soul," he said.
The optimum amount of time for sleep is between seven to eight hours, he said. When more than nine hours of sleep can be an indicator of other health problems.
Scientists are not clear about how to actually damage the cardiovascular system of sleep deprivation, or both causal relationship. But Prof Cappuccio said there was evidence that it affects the endocrine system, which regulates hormone production.
It could also lead to impaired glucose tolerance and reduced insulin sensitivity, which can lead to diabetes, and high blood pressure.
Prof Cappuccio last year published a review of 16 studies involving a total of 1.3 million people, which shows that people who sleep less than six hours 12 percent more likely to die before the age of 65, than those who slept between seven and eight hours.
Dr. Sharlin Ahmed, from the Stroke Association, said sleep either too much or too little can damage our health. "This study highlights the importance of getting six to eight hours on a regular basis to sleep less or more than this can increase a person's risk of stroke," he said. He hopes there is continued research in this regard.
