New Study: Losing Just 6 Hours of Sleep May Increase Diabetes Risk
According to findings of a new study published in the American Journal of Physiology-Endocrinology and Metabolism, losing a single night’s sleep may affect the liver’s ability to produce glucose and process insulin, increasing the risk of metabolic diseases such as type 2 diabetes.
The Importance of Sleep
The Centers for Disease Control and Prevention (CDC), estimates that 35% of United States adults do not get enough sleep. Studies have shown healthy sleeping patterns can help promote good memory, may curve inflammation, spur creativity, improve performance, sharpen focus and attention, and support healthy weight and a decrease in stress.
A team of researchers from Toho University Graduate School of Medicine in Japan, with the understanding that sleep deprivation has been associated with eating more, moving less and having a higher risk of developing type 2 diabetes, set out to find out “whether glucose intolerance was due to the changes in food intake or energy expenditure or to the sleep deprivation itself.”
The Sleep Study
The researchers used two groups of mice for the study – one group was kept awake for six hours each night (to portray “sleep deprivation”), while the control group was allowed to sleep as desired. The research team offered unlimited high-fat food and sugar water – mimicking lifestyle-related food choices that people make – to both groups prior to the study. During the sleep/wake period, the animals had limited opportunity for physical activity.
Results of the Sleep Study
Glucose levels and fat content of the liver were measured immediately after the trial period. Results showed blood glucose levels were significantly higher in the sleep deprivation group than controls after one six-hour session of wakefulness. Triglyceride (fat) levels and the production of glucose in the liver also increased in the sleep deprivation group after a single wake period.
These finding suggest that “intervention studies designed to prevent sleep deprivation-induced hepatic steatosis and insulin resistance should be performed in the future.”
Natural Sleep Remedies
According to Millie Lytle, ND, CNS, former Director of Nutrition for InVite® Health –
- Supplementation of Magnesium has been shown in numerous clinical studies to improve subjective measures of insomnia such sleep efficiency, sleep time, early morning awakening in one study on elderly people. It also reduced stress signaling, such as lowering cortisol and increased melatonin levels in the same population.†
- Melatonin regulates the body’s circadian rhythms, your body’s 24-hour clock that regulates your sleep-wake cycle. The levels of melatonin in the blood are highest prior to bedtime. When Melatonin is high, cortisol is low. Melatonin is also essential for the synthesis of Serotonin. As a supplement, it re-calibrates your 24-hour body clock for shift workers or those who work nights.†
- L-Theanine, an extract from green tea, is excellent for persistent thoughts. Day or night, L-Theanine helps you calm down by increasing blissful alpha-waves in the brain, before bed or in the middle of the night.†
