Poor Sleep Linked To Obesity, Diabetes Risk

A new study has warned that poor sleep ups the risk of being overweight and also developing diabetes at a later stage. For the study, the details of which appeared in the journal PLOS ONE, the team involved 1,615 adults and the participants reported how long they slept and kept records of food intake.

This study strengthen the evidence
Previous researches have shown that insufficient sleep could contribute to the development of metabolic diseases such as diabetes, and this study strengthen the evidence. According to the scientists, the people who were sleeping an average of six hours a night had a waist measurement that was 3 cm greater than individuals who were getting nine hours of sleep a night. “The number of people with obesity worldwide has more than doubled since 1980. Obesity contributes to the development of many diseases, most notably Type 2 diabetes. Understanding why people gain weight has crucial implications for public health,” said Greg Potter from the University of Leeds, UK.

Decrease in the levels of HDL cholesterol
Further, people with shorter sleep duration also had a decrease in the levels of HDL cholesterol — also known as good cholesterol — which helps remove ‘bad’ fat from the circulation and protect against conditions such as heart disease. “Because we found that adults who reported sleeping less than their peers were more likely to be overweight or obese, our findings highlight the importance of getting enough sleep. How much sleep we need differs between people, but the current consensus is that seven to nine hours is best for most adults,” said Laura Hardie, a reader at the varsity.
