We do research to find out if common sense is correct, sometimes it isn’t. In this case, nwhat you view as common sense was found to be incorrect.

no, i think it mostly says that if you are healthy & therefore genetically predispositioned for good sleep then you can still disrupt it by not following these 4 things

but if you are predispositioned for bad sleep then these 4 things probably won't help

"Study participants were healthy individuals aged 18–65 years, who were able to provide written informed consent. Exclusion criteria included ongoing inflammatory disease; cancer in the last three years (excluding skin cancer); long-term gastrointestinal disorders including irritable bowel disease or Celiac disease (gluten allergy), but not including irritable bowel syndrome; taking immunosuppressants or antibiotics as daily medication within the last three months; capillary glucose level of >12 mmol l–1 (or 216 mg dl–1), or type 1 diabetes mellitus, or taking medication for type 2 diabetes mellitus; currently experiencing acute clinically diagnosed depression; heart attack (myocardial infarction) or stroke in the last 6 months; pregnancy; and vegan or experiencing an eating disorder or unwilling to consume foods that are part of the study. "

Are you saying that those people who were excluded were predisposed to poor sleep or predisposed to poor sleep because of underlying conditions which typically cause poor sleep?


DopeDetective t1_ix40v3h wrote

right they excluded a bunch of people who are genetically predisposed to poor sleep due to underlying conditions and then claimed there's no genetic relationship.

like if you cant eat high carb due to a genetic condition then you're never going to be able to meet those 4 requirements & therefore genetically predisposed to poor sleep.

Ah, i think I see where we are not agreeing: I think they are saying that there is not a genetic factor for poor sleep that is “pure”. As in not secondary to other factors, but a primary genetic factor.

Yep, you have been correct this entire time. This sub is sometimes insufferable.

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.
