Theta is associated with many beneficial changes in the body. A group of
researchers studied the effect of various frequencies on DNA repair. They found
that electromagnetic fields between 7.5 Hz and 30 Hz were able to enhance
molecular bonding (Tekutskaya, Barishev, & Ilchenko, 2015). Within that range,
9 Hz proved most effective.
There are many studies of human and animal cartilage cells, because repair of
these cells is essential to wellness, as anyone who has had a sprained ankle or a
pulled ligament can attest. A research group using pulsing electromagnets found
that human cartilage cells are regenerated by the frequency of 6.4 Hz, right in the
middle of the theta band (Sakai, Suzuki, Nakamura, Norimura, & Tsuchiya,
1991). This frequency also increases the activity of antioxidants, the molecules
that neutralize the free radicals regarded as the most common cause of aging.
A research group at the Toho University School of Medicine in Japan looked
at the EEG signatures of subjects practicing deep abdominal breathing. They
found that their levels of the “feel-good” neurotransmitter serotonin rose, and
theta as well as alpha and delta waves increased (Fumoto, Sato-Suzuki, Seki,
Mohri, & Arita, 2004). Another study found that frequencies alternating between
Mohri, & Arita, 2004). Another study found that frequencies alternating between
5 Hz and 10 Hz produced a large reduction in lower back pain in 17 patients
(Lee et al., 2006).
A pair of Russian scientists examined the effect of frequencies between 5.5
Hz and 16.5 Hz on DNA in a water solution. They found that the molecules were
most highly stimulated at 9 Hz and that the effect was more than twice as great
as it was on the untreated control molecules (Tekutskaya & Barishev, 2013).
Alpha
If you’ve undergone neurofeedback or biofeedback training, you’ve heard a
lot about alpha. These trainings are designed to educate you to induce an alpha
brain wave state at will. Alpha oscillates at 8 to 13 Hz.
Alpha is right in the middle of the frequency bands, between beta and gamma
above and theta and delta below. Legendary brain pioneer Maxwell Cade
believed that alpha serves as a bridge between the upper and lower frequencies.
Beta reflects the activity of the conscious mind, while theta and delta represent
the subconscious and unconscious minds. Cade believed that the alpha bridge
connects the conscious mind with both the intuitive wisdom of the unconscious
and the nonlocal resource of the universal field. A truly integrated person is able
to generate large amplitudes of alpha.
It turns out that alpha also does good things for our bodies. It improves our
levels of mood-enhancing neurotransmitters such as serotonin. When the alpha
brain wave level increased in a group of exercisers, they gained a boost in
serotonin, and their emotional state was elevated (Fumoto et al., 2010). In
another study, Zen meditators received the same benefits from cultivating an
alpha state (Yu et al., 2011).
