Weekday sleep debts are common among teenagers like us, but do you know that Losing 30 minutes of sleep per day may promote weight gain and adversely affect blood sugar control. Wenona and I will introduce the study of the relationship between sleep and health to you.

Leading by Professor Shahred Taheri, a diabetes trail divides 522 newly diagnosed patients with type 2 diabetes mellitus into 3 groups with usual care, physical activity intervention, or diet and physical activity intervention. Their changes in weight and height, waistline and blood sample is recorded though a 7-day sleep diary to indicate their obesity status and insulin sensitivity.

Let’s look at a text from the article: “weekday sleep debt may lead to long-term metabolic disruption, which may promote the onset of, or exacerbate the progression of, type 2 diabetes mellitus.”

What does this mean?

It means that Sleep loss can cause obesity, insulin resistance, and hyperglycemia.

Do you know what is insulin resistance? Insulin is produced in the pancreas, which is down below your stomach. Insulin resistance is when the cells cannot respond to the normal insulin effectively. Other than being absorbed, glucose will stay in the blood. As a type of sugar, glucose in excess will cause hyperglycemia.

Hyperglycemia simply means “High Blood Sugar”, hyper means excessive, glyc means sweet, and emia means of the blood. It is also one of the main causes of type 2 diabetes. The combination of insulin resistance and hyperglycemia will raise the possibility of weight gain and type 2 diabetes.

From the study’s results, it shows that At baseline, those with weekday sleep debt were 72% more likely to be obese.

By 6 months, an obvious association can be made between sleep loss and obesity and insulin resistance.

By 12 months, every 30 minutes’ sleep loss would cause the risk of obesity increase by 17%, and insulin resistance increased by 39%.
