The importance of Delta brainwaves is astounding, especially for brain enhancement. The benefits of increasing the amount of those waves are even more astounding.
According to Richard Hall, Delta brainwaves are associated with the deepest stages of sleep: stages three and four. In stage three of sleep, the percentage of present Delta brainwaves lies below 50 percent. However, in stage four of sleep, the percentage rises above 50 percent. Control Mind exemplifies another distinguishing characteristic of the Delta brainwaves as being that they have the lowest frequency, 1-4 hertz, amongst brainwaves but have the highest amplitude.
Delta Brainwaves and Sleep
Richard Hall goes on to explain that during an average night of sleep, the sleeper begins at the first stage of sleep and moves through the stages to the fourth stage. At this point, they have shifted from a Theta state to a Delta state. The sleep cycle then retracts back through the stages from stage four to stage two. However, the sleeper then enters a stage of sleep known as REM sleep, or rapid eye movement sleep, instead of entering stage one. An entire sleep cycle generally lasts 90 minutes. With each passing 90 minute cycle, the amount of time spent in the Delta states of sleep decreases while the time spent in REM sleep increases.
Physiological Benefits of Increased Delta Brainwaves
Delta Boost states that increasing Delta brainwave activity has several benefits. The release of DHEA, believed to be an anti-aging hormone, is associated with increased Delta brainwaves. The release of melatonin and decreased concentrations of cortisol are also associated with increased Delta brainwaves.
The importance of altering these hormones is explained by The Mayo Clinic staff. They state that DHEA, or dehydroepiandrosterone, is an endogenous hormone released by the adrenal glands that is known to decrease in people upon reaching the age of 30. It is also thought to be depleted by certain medications including insulin and opiates. As it is implicated in maintaining a youthful appearance preventing this decrease or even possibly increasing normal levels of the hormone may have an anti-aging effect after the age of 30.
Melatonin, as described by WebMD, is an endogenous hormone released by the pineal gland which helps regulate the cycles of sleep and wakefulness. Frequent uses of melatonin supplements are to decrease insomnia and prevent jet-lag. In addition, initial research suggests it may be useful in helping individuals regulate their sleep when working on the night shift, treating Seasonal Affective Disorder, decreasing confusion and agitation when first awakening after surgery and reducing chronic cluster headaches. While much additional research needs to be conducted the results of early studies indicate Melatonin may improve the immune system, stop or slow the spread of cancer and slow the aging process.
The Cortisol Connection defines cortisol as a steroid based hormone that increases when an individual experiences stress. This can be problematic when the levels of cortisol become very high or when exposed to the hormone frequently. For some individuals cortisol levels remain above normal constantly. This is problematic as elevated cortisol levels can negatively effect overall health through decreasing immunalogical functioning, altering brain activity, and increasing body fat which in itself can lead to other problems.
Another benefit of increased Delta brainwave activity is the release of the HGH, or human growth hormone, which is secreted from the pituitary gland. This is another hormone that decreases with age and according to HGHtruth.org individuals who suffer from significant decreases may experience fatigue, lowered metabolism, and decreased muscle mass and strength.
Delta brainwaves are believed to stimulate the pituitary gland, and in return, the pituitary gland releases increased amounts of these hormone.
Increased Delta Brainwaves and Connection to Our Deepest Levels of Awareness
Control Mind states that increased levels of Delta brainwaves is linked to heightened states of empathy as well as heightened bliss and a deep connection with our unconscious mind. Connecting to the unconscious mind is a well-sought goal of meditation. Alpha and Theta brainwaves are able to connect the conscious mind with the subconscious mind, but Delta brainwaves, if harnessed at healthy levels, allow for the conscious mind to connect with the deepest levels of awareness within an individual. Another benefit of increased Delta brainwaves is enhanced intuition, or raw instincts we often call “gut feelings.”
Drawbacks to Increasing Delta Brainwaves
Two commonly associated drawbacks to increasing Delta brainwaves are hyperactivity during wakefulness and excessive sleepiness while training your brain. When your brain is trained to increase Delta Brainwaves, it enters the very slowest state of functionality. The central nervous system, or CNS, burns through very little energy. This results in the need for an outlet of energy which manifests in hyperactivity. Strangely, during training however, you are far more likely to be drowsy or sleepy because of the initial association between Delta waves and the deepest levels of sleep.
