Sleeping In Feels So Good, but May Be Unhealthy

Sleeping later on weekends may be bad for you.
Several studies have shown that there is an association between shift work and an increased risk for heart disease and diabetes. Now a new study, in the Journal of Clinical Endocrinology & Metabolism, has found a similar association in people whose sleeping schedules change on the weekend.
For seven days, 447 men and women ages 30 to 54 wore devices that measured movement and tracked when they fell asleep and woke.
Almost 85 percent of the group went to sleep and woke later on their days off than during the workweek. The researchers found that the greater the mismatch in sleep timing between weekdays and weekends, the higher the metabolic risk. Sleeping late on days off was linked to lower HDL (good) cholesterol, higher triglycerides, higher insulin resistance and higher body mass index. The associations persisted after controlling for physical activity, caloric intake, alcohol use and other factors.
“It’s not clear yet that this is a long-term effect,” said the lead author, Patricia M. Wong, a graduate student at the University of Pittsburgh. “But we think of this as people having to sleep and work out of sync with their internal clock, and that having to be out of sync may be having these health effects.”
So we should wake up at the same time every day? Hmmm. Are naps okay?
Not sure on the naps. I think we can sleep in a little, just not drastically later than our normal schedule.
Yeah, the more I read about it, the more I'm convinced a regular sleep schedule is better for health.
These "associative" type studies are always tyrannical in their false pattern precisions and distorted inferences.
Any person that standardizes anything consistently as a lifestyle practice will have it work better for them than having no schedule at all and simply indulging meandering irregularity: arrhythmia always leads to disruptive and destructive variances in physiology in the short-term ... unless and until your body adapts to the challenge of that arrhythmia, or greater pattern in it, if there is one. So napping can work well if you do it consistently to serve and nourish your physical and emotional needs as desired progress.
The value of using greater and lesser rhythms to stabilize our physiologic baselines in any domain (e.g. eating, sleeping, exercise, etc.) is not to be confused with kurtosis, which is the infrequent challenge to our baseline norms as a provocative injunction to improve our current performance in the direction of greater positive results, or a wider variance that leads to intentional growth (e.g. fasting, polyphasic sleep, high intensity training, etc.)...
