. On the other hand, the night owls were less sensitive to insulin and burned more carbohydrates rather than fat as an energy source.differences exist between early birds and night owls, Malin said. But one aspect could be a mismatch between their natural body cycles and the actual times that people go to sleep and wake up.
“A potential explanation is they become misaligned with their circadian rhythm for various reasons, but most notably among adults would be work,” he said. For instance, a night owl may prefer to go to bed late but still need to wake up early to go to work or look after children. This could force them out of alignment with their circadian rhythm.
The study findings could have implications for sleep-wake patterns, including the health risks of nightshift work and annual time change policies, USA Today reported. “If we promote a timing pattern that is out of sync with nature, it could exacerbate health risks,” Malin said. “Whether dietary patterns or activity can help attenuate these is an area we hope becomes clear in time.”Experimental Physiology: “Early chronotype with metabolic syndrome favors resting and exercise fat oxidation in relation to insulin-stimulated non-oxidative glucose disposal.”© 2022 WebMD, LLC.
