A Korean research has found that people who sleep less than six hours a night may suffer from risk factors that increase their chance of having diabetes, heart disease and strokes. The researchers said that people who do not get enough sleep should be aware of these factors.

Lead researcher Dr. Jang Young Kim of Yonsei University in South Korea explained about metabolic syndrome. As per Kim, a mix of risk factors including high blood sugar, high cholesterol and extra fat around in midsection and high blood pressure and excessive amount of fat in the blood is called metabolic syndrome.

As part of the study, the researchers have followed around 2,600 adults for more than two years. After observing them for the mentioned period, the researchers came to know that those who have not slept for at least six hours a night were 41% more risk of developing metabolic syndrome in comparison to those who sleep six to eight hours.

The researchers based their findings on two lifestyle surveys. The follow up periods were between 2005 and 2008 and then between 2008 and 2011. Less sleep was linked with around 30% increased risk of high blood pressure and excess belly fat and 56% increased risk of hypertension in comparison to those who were able to get more hours to sleep.

It has been suggested that people should give a close look at their daily routines and ensure that they get proper rest.
