Prof. Tami Martino, Biomedical Sciences, was interviewed by New Scientist June 6 for a story on how sleep patterns can affect health. The story looked at how social “jet lag,” or keeping late nights on weekdays and trying to catch up on sleep on the weekend, could harm heart health. Martino said frequently shifting sleep times could cause your body to fall out of sync, negatively affecting heart health. She studies the biological clock, circadian rhythms and cardiovascular disease.
