It has long been known that obstructive sleep apnea is associated an increased risk in heart conditions. The sleep disorder contributes to high blood pressure, atrial fibrillation and heart attacks.

The ‘munchies’ describes a sudden strong desire for food. The phrase, and the phenomenon, has long been associated with the use of marijuana, as after smoking pot people have a tendency to want to eat a lot, particularly junk food and sweets. But a new report has revealed that the munchies also appear after insufficient sleep, and researchers believe that they now know why.

The study was conducted as a collaboration between the University of Chicago’s Section of Endocrinology, Diabetes and Metabolism, the University of Chicago Medicine and the Medical College of Wisconsin, and was led by Erin Hanlon, PhD, research associate and assistant professor. They found that insufficient sleep raises the level of a specific substance that is a natural appetite stimulant. This, in addition to already-known shifts in the hormone levels of leptin and ghrelin, provide more evidence as to why lack of sleep contributes to weight gain and obesity. According to Hanlon, “Past experimental studies show that sleep restriction increases hunger and appetite. The mechanism for overeating after inadequate sleep may be an elevation in this endocannabinoid molecule, called 2-arachidonoylglycerol, or 2-AG.” Continue reading →

If you ask the average American what’s on their wish list for improving the quality of their lives and the way that they feel, most people will have either losing weight or getting more sleep at the top of their list. The funny thing is that there’s a good chance that if they accomplish one, the other will follow. There’s a growing body of evidence indicating that sleep and obesity are closely tied to one another. Not only do sleep-deprived people have a higher risk for obesity, but people who are obese have a higher risk of experiencing trouble falling asleep, and also have a high potential for being diagnosed with obstructive sleep apnea, a serious health condition.  Continue reading →
