Most of us agree that gardening, from tending flowers on the porch to working a larger vegetable patch, relieves stress and lightens our mood.
Those lucky enough to have thorn-free lawns or garden paths where they can walk (or sit) barefoot, speak to similar relaxation benefits. In fact, studies have demonstrated blood pressure reduction just by sitting with your feet in the grass.
Research since the late 90s is shedding light on why this is. One reason is that the surface of the earth is loaded with “free” electrons which enter the body through the soles of bare feet when walking, or through the hands when working in soil.
These electrons help reduce inflammation in our body by quenching “free radicals”. These are rogue molecules that are missing electrons, who then try to steal them from other molecules nearby. This can create more free radicals and increase inflammation in a run-away manner. Anti-oxidants commonly taken as supplements or consumed in food help decrease inflammation by a similar donation of electrons.
Other health benefits of “Earthing” or “Grounding” (see earthing.com), include a natural thinning of the blood, resulting in better circulation and lower blood pressure. This is due to a boost in the “Zeta Potential”, which is the naturally occurring force between red blood cells that cause them to repel one another.
Other studies show a calming of the nervous system and a reduction of stress hormones. A U of A researcher even showed potted sunflowers grew better if they were grounded.
