Sleeping too long or too much causes cancer? (and other questions)

[timeuser84]

Hi, just wanted to know does sleeping to much or to long cause cancer? Does not sleeping enough cause cancer? does not sleeping enough or to much raise blood pressure and possibly give me diabetes? Does all citrus acid fruits like lemons bad for the teeth and damage tooth enamel?

We are often led to believe that certain activities or habits cause cancer but in fact all that these studies show is that those who do these activities or have these habits have a larger number of cancer cases than those that don't. Causal relationship is not demonstrated. People who don't get enough sleep do so for some reason that in fact may be the cause of cancer but what?

Please do not spam us with multiple very general and somewhat problematic questions.
Cancer question (but the same applies to the other questions about diabetes and tooth enamel) answered:

First off, consider that you probably got this idea from a non-science based popular source like the health column in a newspaper, or facebook, or whatever. Mostly likely poor to awfully poor information.

So, short answer = No.

@Ygggdrasil has posted on the subject. He is a cancer researcher.

1. Go to the top bar
2. click search,
3  go into advanced search
4 cancer is the keyword you want
5 posted by Ygggdrasil
6. run the search

You will find lots of good links to cancer causes and unproven causes.

More generally ---
Consider going to WebMD or NIH and search there, you'll find white papers there that are meant for people with modest science backgrounds. Start there for very general health questions like the one you just asked.

Here is a great one from NIH on your question i.e., "cancer risk":

In general, lack of sleep is associated with increased risk of a number of health problems such as obesity and heart disease. However, as @gleem noted, these studies are subjected to interference from many confounding factors. Lack of sleep can stem from number of different causes and it is not clear whether it is these underlying issues (and not lack of sleep per se) that are associated with increased risk of health problems

For some good information about the health problems associated with a lack of sleep see:

In terms of cancer, sleep is generally not thought of as a major risk factor for cancer. Research suggests that those who work night shifts may have an increased risk of cancer, though whether this is due to disruption of sleep cycles/biological clocks/light exposure or some other factors (e.g. people who work night shifts are likely lower on the socioeconomic scale) is still not clear. Here's a page discussing some research connecting sleep and cancer:

@Jim and everyone else. thanks for the info as well as help.

@Jim I was not spamming or if I was, it was not my intent, sorry. I posted this here so I could weed out or sift pass the BS to find out the truth and facts about this stuff. for example, I found contradictions on the web about citrus acid fruits like lemons, 1 source saying its good for teeth, gums and great for teeth animal while another says the opposite, that its bad for the teeth, makes it rot or damages tooth enamel. Just to double check, when you say the short answer is no, do you mean that NO, citrus acid fruits do not do anything bad to the teeth/gums OR do not damage teeth enamel?
