Hi Oem7110, there's a video on this blog post that will give you some insight: https://biology-forums.com/index.php?article=1327

If serotonin only last 3 - 8 hours, then increasing and decreasing the levels of serotonin makes people's emotion unstable during this period of time.  Referring to following articles, since 95% of serotonin is produced in the gut, when someone has a leaky gut, the balance of serotonin is disturbed which can cause depression and eating disorders.  I would like to know on how and what conditions serotonin is generated in the gut.

Do you have any suggestions?
Thank you very much for any suggestions :>

That's a *very* interesting finding, and it's something I did not know.

Serotonin is manufactured in the brain and the intestines. The majority of the body's serotonin, between 80-90%, can be found in the gastrointestinal (GI) tract. It can also be found in the blood platelets and the central nervous system (CNS).

See if you can gain access to this study, it outlines the steps for you:

I find it amazing how gut bacteria actually can influence a person's mood. It goes along with the saying, I have a "gut feeling" :P

Here's an interesting read: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4262908/

Since 95% of serotonin is produced in the gut, referring to following articles, I would like to know on how exposing to sunlight would increase the brain’s release of serotonin (not the gut?). 
What chemical process is going on during exposing to sunlight?
Does anyone have any suggestions?
Thanks, to everyone very much for any suggestions :>

While too much of the sun’s warm rays can be harmful to your skin, the right balance can have lots of mood lifting benefits.

Sunlight and darkness trigger the release of hormones in your brain. Exposure to sunlight is thought to increase the brain’s release of a hormone called serotonin. This is associated with boosting mood and helping a person feel calm and focused. At night, darker lighting cues trigger the brain to make another hormone called melatonin. This hormone is responsible for helping a person feel sleepy and go to sleep.

Without enough sunlight exposure, a person’s serotonin levels can dip low. Low levels of serotonin are associated with a higher risk of seasonal affective disorder (SAD). SAD is a form of depression that is triggered by changing seasons.

A mood boost isn’t the only reason to get increased amounts of sunlight. There are a number of health benefits associated with catching a moderate amount of rays.
