From the magazine, Natural Awakenings,a free alternative health magazine that I picked up at Whole Foods…

Most people today lead excessively nature-separated lives. Some doctors believe that this disconnect leads to poor mental health. Ecopsychologists believe that reconnecting people with nature will improve mental health. Anyone who's experienced nature—whether in open backcountry or a sunny backyard, whether in the context of sea or stars—knows how nature renews and re-creates us.

So maybe traffic, concrete and skyscrapers really are driving us crazy. Polluted inorganic environments may well be contaminating our heart, mind and spirit. A 2004 study even suggests that kids who engage with nature are less apt to have attention-deficit-hyperactivity disorder (ADD). And a Univeristy of Michigan study found that people with views of nature from home are happier."

This is a good reminder to spend more time outdoors. Interestingly, we can find scientific evidence for "ecopsychology" in the field of harmonics and physics. The resonant frequency of the Earth's electromagnetic shield is referred to as The Shumann Resonance, and although this frequency varies, it's around 7.8 Hz. Apparently this Earth frequency has extremely beneficial effects on living organisms, including humans.

According to a site about electromagnetic frequencies…

The Schumann Resonances are quasi-standing electromagnetic waves that exist in the Earth's 'electromagnetic' cavity (the space between the surface of the Earth and the Ionosphere). So long as the properties of Earth's electromagnetic cavity remains about the same, these frequencies remain the same. Presumably there is some change due to the solar sunspot cycle as the Earth's ionosphere changes in response to the 11-year cycle of solar activity.

Depending on your point of view, living beings either evolved in this natural electromagnetic environment or were created with Divine Intelligence to live in harmony with it. One thing is certain: Since life began, the Earth has been surrounding all living things with this natural frequency pulsation. Many experts believe that the wide spectrum of artificial man-made EMF (electromagnetic frequency) radiation masks the natural beneficial frequency of the Earth.

Electropollution may cause us to feel more stressed, fatigued and "out of balance." Laboratory research has shown that exposing living cells to the Schumann Resonance had the effect of "protecting" them from ambient EMFs, allowing the cells to increase their immune protection, and decrease the absorption of depression-inducing chemicals.

[This connects with the "ecopsychologists" who believe that people often develop depression, mood swings and mental problems when they spend too much time indoors.]

Some researchers believe that by producing a 7.83 Hz pulse with a field generator (Schumann device), we can counter the effects of the irritating man-made fields. [Man-made electromagnetic fields are produced by radiation from power lines, cell phones, microwaves, and most technology. According to scientists, depending on where we live, we spend a large amount of time existing in 50 and 60 Hz power fields.] By replicating the Earth's natural rhythm, we may be providing ourselves (at least in our immediate vicinity) with a more healthy environment."

Even more interesting…

The Schumann Resonance lies within the alpha range (human brain waves are normally in one of four states–beta, alpha, theta, or delta). Alpha waves range between 7-12 Hz. This is a place of deep relaxation, but not quite meditation. In Alpha, we begin to access the wealth of creativity that lies just below our conscious awareness—it is the entry-point that leads into deeper states of consciousness.

Endorphins are naturally generated in the alpha state, and we feel more relaxed. Perhaps this explains why we feel better after spending time outdoors.
