Internet addiction and insomnia
are self-stimulating behaviors.
People with conditions
such as allergies tend to crave foods that they are allergic too. These
foods that they crave exacerbate their allergies, causing an increase in
serotonin (along with the histamine).
For the same reason, to
increase serotonin, people with conditions such as allergies also seek
increased exposure to light.
In addition to the
increased serotonin level, light also suppresses melatonin and the immune system,
and exacerbates conditions such as allergies. Stress can also cause a
release of adrenaline, which also depresses the immune system.
Overexposure to light
leads to problematic conditions such as light sensitivity, convergence
insufficiency, and laterality issues. As a result, the brain produces more
theta brainwaves, more serotonin, and more adrenaline.
Stress from these
conditions lead to adrenal fatigue and depression, causing the sufferer to
again seek to increase their serotonin level through activities such as
surfing the Internet, staying up late, and by engaging in any other
activity which increases serotonin or adrenaline levels.
