Untreated sleep apnea shown to raise metabolic and cardiovascular stress — ScienceDaily

Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects. A report of the study’s findings, published in the August issue of The Journal of Clinical Endocrinology & Metabolism, adds further support for the consistent use of continuous positive airway pressure (CPAP), a machine that increases air pressure in the throat to keep the airway open during sleep.

Jun emphasized that the study was limited by studying people with severe OSA and obesity, thus limiting the ability to apply the findings to all OSA patients. The researchers also did not compare CPAP use to a sham CPAP control group to exclude a potential placebo effect

North Atlantic Clam That Lives for Centuries Yields Insights on Cardiac Aging | NCCIH

The Arctica islandica, or ocean quahog, is the longest-living, non-colony-dwelling animal ever identified; so far, the oldest identified specimen survived to age 508 (age is identified by counting shell growth rings).
