Lifestyle changes may reverse aging in cells: A new study led by Dr. Dean Ornish suggests that certain lifestyle changes, including a plant-based diet, an exercise regimen, and meditation and yoga, may “turn back the biological clock and reverse aging on a cellular level.” Subjects of the study (all men diagnosed with low-risk prostate cancer) who adopted this better lifestyle over several years had a 10% increase in the lengths of their telomeres, “the caps at the ends of chromosomes that protect them from deterioration.” In men who did not adopt these new changes, telomere length shortened by 3%. Telomere length is thought to significantly impact the aging process.

Beauty rest is a real thing, study shows: Can sleep really make you more attractive? A new study says yes. The study used a “face mapping” technique to track the facial appearance of 20 middle-aged people with sleep apnea both before and after they began treatment. Sleep apnea “affects millions of adults and is characterized by snoring and breathing interruptions, which result in reduced quality of sleep.” After treatment with a CPAP machine, which acts as a breathing mask, “patients’ foreheads were less puffy and faces less red.” Subjects also benefited from “a reduction in forehead wrinkles after treatment.”
