Doctors have long determined that each of us should sleep eight hours a day. But for too long, as well as too short sleep may lead to undesirable consequences, say scientists. Any deviation from the golden mean can dramatically increase the risk of illness and even death. Why is it so dangerous, and how much sleep, says the BBC.

How long does it take to the human body fully restored power? Almost all say that eight hours. However, most modern medical studies have shown that it is too much and too long sleep can cause health problems.

Eight hours of sleep – too much?

Greg Jacobs Professor at the Center for sleep disorders at the Medical Faculty of the University of Massachusetts. According to him, over the past decade research has shown that eight hours of daily (or rather nightly) sleep can hurt you.

« A total of 34 different studies , – says Greg Jacobs . – Doctors tracked behaviors and health status of more than two million people. It turned out that the relationship between sleep duration and life expectancy can be represented in the form of the letter «U ».

« The lowest mortality observed in the lowest part of the arc« U », and this point corresponds to seven hours of daily sleep. Once you begin to move away from the ideal of how to more prolonged sleep and sleep deprivation aside, the risk of early death begins to grow. The risk increases with fans to sleep faster than those who sleep less than normal ».

So, if you believe Dr. Jacobs, the ideal is a seven-hour sleep. Sleep less, and you have a real chance of dying sooner; Sleep more – and the chance to timeless transition into another world becomes even higher.

inexact science

Calculate the exact time SPLA, it is difficult: as if asleep in the truck?

However, another expert on sleep , professor of cardiovascular medicine Franco Capucci of the University of Warwick in the UK, advises not to panic. All that is between six and eight hours, from his point of view, is the norm. At least because quite accurately measure the duration of sleep is extremely problematic.

« In the study of sleep – he says – we tend to rely on their own assessment of people. And they, for the most part, unable to up to a minute to say how long they slept ».

Not only is public opinion polls are rarely a good source of data for scientific analysis, but as it turned out, we all tend to exaggerate how much we slept.

So says Professor Capucci, if you are like three quarters of the population of the United Kingdom, sleep six to eight hours a day, then you worry absolutely nothing.

How dangerous material transfer with the lack of sleep?

Anyone who sleeps or less than six to eight hours or more to get such risks health problems like high blood pressure, diabetes and cardiovascular disease.

interspersing dangerous lack of sleep, scientists say

« If you sleep longer than eight hours, or less than six, the risk to make any of these diseases increases dramatically. And this, in turn, leads to an early death », – says Franco Capucci.

But how big is this risk? Scientists have found that among those who are chronically enough sleep, mortality was 12% higher than that of the golden mean sleeping for six to eight hours.

Golden number seven

So how much do we need to sleep? Despite the fact that in most cases our own sense of trust is difficult, Greg Jacobs believes that the ideal can be calculated.

If you love to lie in bed, then most likely, you all right

« Each Spring National Organization sleep in US polls several thousand adults. It turned out quite interesting pattern: most of them claim that the average sleep seven hours a day, which, incidentally, corresponds to the average sleep duration and worldwide ».

Dr Jacobs believes that it is quite possible, these same seven o’clock are a natural cycle for a healthy brain.
After seven hours of sleep most adults say they feel rested and refreshed, and only 5% complain of drowsiness and fatigue.

However, if you are naturally love to soak up under the covers, and then feel just fine, then most likely you are not threatened. Indeed, so far no one with an accuracy not shown that the propensity to lie in bed leads to untimely death.
