Abstract
This study examined the impact of academic stress on salivary cortisol concentrations and lactic acid bacteria activity. Whole, unstimulated saliva samples and faecal samples were collected from 23 healthy undergraduate students (23.0+/-6.8 years; range 18-44) over two 1-week periods: during the beginning of semester (low-stress baseline condition) and during the first week of exams (high-stress condition). Students also completed a series of questionnaires measuring perceived levels of stress, gastrointestinal symptoms, and nutritional intake. Significant findings indicated that faecal lactic acid bacterial levels were lower during the high-stress condition. Paralleling this, students rated perceived levels of stress as being greater during the exam period compared to the baseline condition. The findings from this study have provided further insight into the link between stress and gastrointestinal flora activity in humans.

You should check out Bruce Lipton.

Here is a short interview:

I watched his long lectures (over two hours) on google videos a year ago. Truly magnificent stuff...

Wow, this is actually pretty amazing!

It doesn't say much about possible extraneous factors though. I would like to know: were they eating the same foods during low and high stress? I also imagine they were sleeping less? There could be a lot more to this.

Interesting nonetheless.

"why is it interesting" Haha. Studies like these basically prove that emotional well-being is just as important, if not more important, than things like diet to the true health of beings.

this study already states the obvious, and doesn't provide a specific link to acne related conditions. I am not sure why this is interesting at all.

the connection between the cns and overall health is a given?

yea, no obvious link to acne. but we cant talk about acne, without talking about what health is, but the bacteria in the gut is pretty much linked to the entire structure of your body, so its important. And the reason why it so interesting is because we still know little about these bacteria and their role in health and disease, some of the techniques to study the bacteria have just recently been developed. We are at the frontiers of science and biology.

It also gives a clue to how emotions can effect the body, and precisely how.
