A regular sleep schedule tends to have a positive effect on your metabolism

Health

Regular sleep and wakefulness can protect your metabolism. A new study combines habits with fewer opportunities for developing risk factors that make up the metabolic syndrome, such as high blood pressure, obesity, and high cholesterol levels.
Metabolic syndrome is a group of disorders that can increase the risk of type 2 diabetes, stroke, heart disease and other serious diseases.

The researchers in the latest study examined the relationship between sleep variability and the development of metabolic risk factors in 2,003 people aged 45 to 84 years.

They found that every 1 hour from day to day there was a 27% increased risk of developing metabolic risk factors.

The National Institute for Heart, Lung and Blood (NHLBI), which is part of the National Institutes of Health, funding this research, appears in the journal Diabetes Care.

“Many previous studies,” said survey author Tianyi Huang, who works as an epidemiologist at Brigham and Women’s Hospital in Boston, Massachusetts, “has shown a link between lack of sleep and an increased risk of obesity, diabetes and other metabolic disorders.”

However, what this study has not yet explained is whether irregularities in sleep and the duration of sleep can also be factors.

“Our research shows that even after a person’s sleep counts, and others are related to lifestyle factors, each one hour difference at night or night’s sleep duration increases the effects of a destructive metabolism,” Juan added. .

Metabolic syndrome and risk factors

There are five risk factors that make up the metabolic syndrome.

You can only have one risk factor, but most likely have more. Doctors diagnose metabolic syndrome if there are three or more risk factors.

For the latest research, the researchers have defined the definition of metabolic risk factors in the National Program for the Treatment of Cholesterol (NCEP / ATPIII). In short, this is:

  • Talia are equal to or greater than 102 cm (cm) or 40.2 inches for men and 88 cm (34.6 inches) and larger for women.
  • Blood triglyceride levels of 150 milligrams per deciliter (mg / dl) or higher.
  • HDL cholesterol levels are below 40 mg / dL for men or under 50 mg / dL for women.
  • Blood pressure is equal to or greater than 130/85 millimeters of mercury (mmHg) or treatment for high blood pressure.
  • Fasting blood sugar is equal to or greater than 100 mg / dl or treatment for diabetes.
  • Waist size is a measure of central obesity. Too much fat in the abdominal area can increase the risk of heart disease, more than too much fat in the thighs or other body parts.

HDL helps transport cholesterol from the arteries. If not enough, it can increase the risk of heart disease.

Blood pressure is the pressure on the arterial wall that results from pumping blood to the heart. If this rises and remains, this can help build plaque in the arteries, which causes damage to the heart.

When fasting blood glucose reaches 100 mg / dL, this can be an early sign of diabetes. The risk of cardiovascular disease and other cardiovascular diseases increases significantly in diabetes.

Strong indication of a causal relationship

The researchers used data from men and women who had participated in the NHLBI-sponsored multiethnic study on atherosclerosis.

Between 2010 and 2013, participants wore active wrists for 7 days. This device records 1 week a day and sleeps. At that time, men and women also did sleep records and filled out questionnaires about lifestyle, sleep habits, and other health information.

Media persecution lasted for 6 years until 2016 and 2017. During this time, researchers have identified “metabolic disorders”.

Michael Twery is the director of the NHLBI National Sleep Disorders Center. He said one of the strengths of this study was the fact that he used “objective indicators” and large and “different” sample sizes.

Other strengths include not only “current factors” captured in the survey. Over time, he has conducted a “prospective analysis” that allows researchers to “assess whether irregular sleep patterns can be linked to metabolic disorders in the future.”

The analysis showed that individuals with the greatest differences in sleep time and their number of hours of sleep were also most likely to have metabolic risk factors. The relationship also does not seem to depend on the average sleep duration.

When looking at tracking data, the researchers found a similar relationship. The participants with the greatest variation in length of stay and their sleep duration were also the most likely to develop later metabolic conditions.

Although not proven, the authors argue that these results reinforce the argument that there is a causal relationship between irregular sleep patterns and metabolic syndrome.

“Our findings show that having a regular sleep routine has a beneficial effect on metabolism,” said study co-author Susan Redlayn, who worked on the sleep ward and circadian disorders at Brigham and Women hospital as a senior doctor.
