Hitting the Snooze Button

Red Light Therapy to Reduce Glucose Levels

In a two-part study published in the Journal of Sleep Research , scientists surveyed 1,732 individuals and found that 69 percent use the snooze feature on their morning alarm, and of those people, 60 percent usually or always fall asleep between alarms. Snoozing is more common among younger people and night owls. For those using this feature, drowsiness and shorter sleep is more common.

The study also sought to determine the effects of snoozing on 31 habitual snoozers. The first morning, the participants repeatedly hit the button to gain 30 extra minutes, and on the second morning, the participants got up on the first alarm. The researchers reported that 30 minutes of snoozing either improved or did not affect performance on cognitive tests administered directly upon rising, as compared to an abrupt awakening. There were no clear effects from snoozing on cortisol awakening response, morning sleepiness, mood or overnight sleep.

The U.S. Centers for Disease Control estimates that 37.3 million Americans, or 11.3 percent of the population, have diabetes, which means the body does not produce enough insulin, causing too much blood glucose (sugar) to stay in the bloodstream. Over time, diabetes can cause serious health problems, such as heart disease, vision loss and kidney disease.

Researchers from the University of London conducted a study of the effects of red light therapy on blood sugar levels. In the study, 15 participants received 670 nanometers of red light onto approximately 800 square centimeters of their exposed back for 15 minutes. The 15-person control group had the same equipment placed on their back, but the light was not turned on.

The result was a significant reduction in blood sugar levels in the group exposed to red light following a glucose intake by the participants. Over a two-hour period following the therapy, maximum glucose spiking was reduced by 5.1 percent. Red light exposure can be used to reduce blood glucose spikes following meals as a safe, non-invasive treatment for diabetes management at home.

Cold Medicine Found Not to Work

A U.S. Food and Drug Administration (FDA) advisory panel voted unanimously that oral phenylephrine was not effective in unblocking sinuses and clearing stuffy noses. The drug has been in use for nearly a century and is an ingredient in more than 200 over-the-counter decongestants. Drug stores have begun removing these products from the shelves. The decision by the FDA was the result of decades of research and an unwavering commitment by two University of Florida pharmacists to remove decongestants from the market that contained an ingredient that was no better than a placebo.
