New Chemical May Explain "Runner's High"
There is growing evidence that regular exercise boosts people's moods and may even fight clinical depression.
Researchers found that a session of moderate aerobic activity appears to elevate the body's levels of phenylethylamine, a natural chemical linked to energy, mood and attention. When they had 20 healthy young men run on a treadmill for 30 minutes, the average concentration of phenylethylamine in the participants' urine increased 77%.
Because the chemical is similar in some ways to amphetamines, the researchers speculate that phenylethylamine may play a role in the "runner's high."
In addition, the report indicates, research in patients with depression and bipolar disorder has shown they have lower-than-normal levels of the chemical in their urine.

I suspect that this chemical is related to endorphins, driven by the parasympathetic nervous system and therefore is directly dependant upon the way we breathe. There is probably also a need for adequate foods containing phenylethylamine (not to be confused with phenylalinine) so that we get it synergized and balanced with other natural live substances.
Over a period of time amines, which includes phenylethylamine, can build up in your system causing reactions that mimic allergies. That is why we take antihistamines when we get many allergic reactions. Hence the suggestion to get them as naturally, in foods, as possible.

When taken orally, PEA is known to readily cross the blood-brain barrier and be immediately available in the brain. In the brain PEA acts by increasing the concentration of dopamine in the synaptic cleft. Naturally enhancing dopamine transmission in the brain has been associated with greater experience of pleasure.
