PEOPLE who do not get enough sleep are more than twice as likely to die of heart disease.
A British study released yesterday said the reasons were unclear, but researchers said lack of sleep appeared to increase blood pressure.
A 17-year analysis of 10,000 government workers showed those who cut their sleep from 7 hours a night to 5 or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of heart attack death.
The findings highlight a danger in busy modern lifestyles, said Francesco Cappuccio, professor of cardiovascular medicine.
"A third of the population of the UK and over 40% in the US regularly sleep less than 5 hours a night, so it is not a trivial problem," he said.
"The current pressures in society to cut out sleep, in order to squeeze in more, may not be a good idea—particularly if you go below 5 hours."
Previous research has highlighted the health risks of shift work and disrupted sleep.
But the latest study, which was supported by British Government and US funding, is the first to link duration of sleep and mortality rates.

Why Poor Sleep Lowers Your Immune System
Have you ever wondered 'exactly' why we tend to sleep longer when we're sick? As you might already know, we sleep in "sleep cycles". We can categorize these cycles into "light sleep" and "deep sleep." But just HOW important deep sleep is to our immune system?
As you read, it's during the first 3-4 hours of our sleep that we experience the longest period of Stage 3 and Stage 4 sleep. Stage 3 and Stage 4 Sleep is also commonly termed "deep sleep".
• It's during deep sleep that we experience very low brain waves called Theta and Delta brain waves.
• Our blood vessels dilate and all the blood that is usually stored in our organs throughout the day moves into our muscles to nourish and repair them.
• Our immune system also activates during deep sleep to fight disease. This is why people tend to sleep longer when they're sick.
When you don't take proper care of your inner sleeping system, you're usually at risk of "poor sleep". Poor sleep happens for a variety of reasons which I outline in the Sleep Wiz Revitalizing Program, but the main "symptom" is the inability or the difficulty of obtaining proper amounts of "deep sleep".
It's very common for people who travel across many time zones to get sick very quickly, we usually blame this on "jet lag". However, jet lag happens because of the body's natural body temperature rhythm being out of alignment. Jet lag commonly creates a disruption of deep sleep, added with the stress of travel, this is a perfect mixture for lowering one's immune system.
Most people live without being aware of all the actions they're taking in their lives that are completely detrimental to their sleeping system, which are depriving them of energy, and making them SLEEP LONGER than they really need to. Fortunately, there are simple methods to take proper care of your inner sleep system, and strengthen it for maximum performance.
