Off to ACSM this Wed, so drop me a line if you are going to be there! Hope to see some of you there and I will have updates as soon as possible
Another sleep study!
Since we are on the topic of sleep, here is more evidence that sleep may mess up your body. The interesting part is that short and LONG sleep duration seem to have an effect. It will be interesting to see more data on this in the future as it is conflicting on some areas currently (e.g abdominal obesity). There are some other growing data (hahaha, bad attempt at humor) to suggest that lack of sleep interferes with insulin sensitivity which could promote a growing waistline! (REF). In the meantime, your mom was right once again that you need your sleep!
Short sleep duration compared with 7 to 8 hours of sleep is associated with greater risk for metabolic syndrome and metabolic syndrome criteria of abdominal obesity, elevated glucose, and elevated triglycerides, but not BP and HDL cholesterol.
Self-Reported Sleep Duration is Associated with the Metabolic Syndrome in Midlife Adults
Conclusion: "These data suggest that sleep duration is a significant correlate of the metabolic syndrome. Additional studies are needed to evaluate temporal relationships among these measures, the behavioral and physiologic mechanisms that link the two, and their impact on subsequent cardiometabolic disease."
May 21, 2008 — Risk for metabolic syndrome was associated with sleep duration, according to the results of a cross-sectional community-based cohort study reported in the May issue of Sleep.
"Short and long sleep duration have been linked to various risk factors for cardiovascular disease," write Martica H. Hall, PhD, from the University of Pittsburgh School of Medicine in
