Reply to comment by DopeDetective in Study demonstrates that how effectively an individual awakens in the hours following sleep is associated four independent factors: sleep quantity/quality the night before, physical activity the day prior, a breakfast rich in carbohydrate, and a lower blood glucose response following breakfast. by the_phet

This is an incredibly weak argument. They excluded a number of conditions that can affect sleep quality, only some of which are exclusively genetic. And even then, "you're genetically predisposed to a condition that may affect your sleep quality" is a very different statement than "you're genetically predisposed to poor sleep," which is essentially what your initial comment of "I'm unhealthy but I still feel alert in the morning, therefore genetics" was saying.

there's a gene that allows people to be fully rested after 4hrs. so clearly sleep quantity is influenced by genetics. circadian rythm is influenced by genetics.. theres just so much that is influenced by genetics that it just seems misleading to say there is no genetic connection the way they claim

the study says that alertness requires a high carb breakfast & glucose response. some people have a genetic predisposition that makes this impossible & these people were excluded from the study. what am I missing.
