Inconsistent sleep hours increase the risk of obesity and heart problems by one third
Many are waiting for weekends so they can get extra sleep hours, but a new study has revealed that this practice may increase the risk of obesity and heart problems by one-third.
The study, which was funded by the National Heart, Lung and Blood Institute (NHLBI) of the United States NIH, indicates that irregular sleep and inconsistent sleep times may increase the risk of metabolic disorders such as high blood sugar, obesity and high Blood pressure.
The results showed that for every hour fluctuations in sleep the risk of obesity, cholesterol, blood pressure and blood sugar rises by 27%.
“Many of the previous studies have shown the relationship between inadequate sleep, high risk of obesity and diabetes, and other metabolic disorders, but we didn’t know a lot about the,” said Dr. Tiane Huang, epidemiologist at Birmingham Hospital The effect of irregular sleep and high daily volatility in the duration and timing of sleep. “
“Our research shows that even after looking at the amount of sleep that a person has and other lifestyle factors, each hour varies in time to stay in bed from night to night, or sleep per night, doubles the effect of harmful metabolism.”
The researchers examined 2003 men and women aged between 45 and 84 years, for a period of six years.
They were asked to wear special hours for seven consecutive days to keep track of bedtime, in addition to answering questionnaires on sleeping habits, lifestyle factors and other health factors.
The results showed that individuals with significant variations in sleep times, and in the hours they sleep, have a high rate of metabolic problems.
Those whose sleep varied for more than an hour were more susceptible to smoking, had symptoms of higher depression, a rise in total calories, and a sleep apnea index.
The researchers found that increased sleep duration or time fluctuation is strongly associated with multiple metabolic problems, such as low HDL cholesterol, blood pressure, and total triglycerides.
Dr. Susan Redline of the Sleep disturbances department at Brigham Hospital and Women’s hospital said, “Our results indicate that maintaining a regular sleep schedule has beneficial metabolic effects.”
