Advantages and disadvantages of delta brainwave stimulation (0 - 4hz)

Delta brainwaves are the lowest in brainwave frequency: ranging from 0 - 4 Hz, but are the highest in amplitude They are considered the most relaxing brainwave frequency range and are commonly associated with the deepest sleep [stages 3 & 4] and a state of unconscious awareness. Delta brainwaves, like other slower brainwave patterns, are generated in the right hemisphere, though they may be observed in widespread patterns throughout various parts of the brain. The delta brainwave range is associated with empathy, the unconscious mind, and a decreased sense of awareness but also with slow mind.

Advantages of increasing delta brainwaves:

Release of Anti-Aging hormones
One of the associated benefits of increasing your delta brainwaves is the release of anti-aging hormones. The delta brainwave pattern stimulates the release of melatonin and DHEA, 2 powerful anti-aging hormones. The delta brainwaves are also associated with decreased levels of cortisol - a hormone linked to stress that has been scientifically proven to speed up the aging process.

State of empathy
Delta brainwaves can provide you with the ability to read other peoples emotions and determine their feelings at unconscious levels. In healthy amounts, delta brainwaves cause a person to have an advanced state of empathy, understanding, and compassion for others. If you are always able to relate to others and can “read other people’s minds,” you probably have more delta than the average person. If you find yourself getting into trouble for not being considerate enough or for “stepping on other people’s toes,” you may have less overall delta brainwave activity.

Extreme bliss
Advanced meditation practices and yogic traditions have associated the delta brainwave frequency range with a feeling of all-encompassing bliss. Since most people aren’t able to consciously experience the delta brainwave state, it may be tough to feel extreme bliss from the delta waves like the yogis, monks, or advanced meditators. With that said, there have been people that have testified to feeling the bliss associated with the delta brainwave while performing extremely deep meditation.

Advanced healing of body and mind
The delta brainwave rhythm is known to completely rejuvenate, replenish, and heal the entire body and brain. The delta brainwave revives the body after a hard day by rejenerating necessary chemicals while a person is asleep. Due to the deepest levels of relaxation that the delta brainwave provides, the body and mind are easily able to restore themselves after minor stress, a rigorous workout, or after boosting your brain power.

Human Growth Hormone (H.G.H.) Release
The delta brainwave is associated with the stimulation of the pituitary gland, which in-turn, is able to release human-growth-hormone — commonly referred to as H.G.H. It doesn’t release enough for you to skyrocket in height and weight. The delta brainwave will not provide adults with a second version of puberty. With that said, there is evidence that it does release slight amounts of H.G.H. in certain individuals. If you are looking to increase your H.G.H., you should definitely consider using delta brainwave entrainment and evaluate how it works out for you!

Connection with unconscious mind
Though the alpha and theta brainwaves are capable of bridging the gap between conscious thoughts and the subconscious mind, the delta brainwave allows us to connect deeper: it allows us to connect with the deepest possible level of our consciousness. The goal of many meditation practices is to experience and consciously control the unconscious mind. The subconscious mind, or our brain’s right-hemisphere, becomes activated when slower brainwaves like alpha, theta, and delta waves kick in.

Deepest possible level of mind / body relaxation
Delta brainwaves while a person is conscious or awake, are extremely rare. However, advanced meditators and infants, are 2 groups of people that are able to enjoy the deeply relaxing benefits of the delta brainwave. Remember what you felt like when you were an infant? Probably not - the delta brainwave is associated with extreme relaxation, yet completely unconscious mental processes.

Perfect intuition
Ever have a powerful gut-instinct that helped you make a good decision? Or a gut-instinct that you should’ve followed? If we get ourselves too caught up in the upper brainwave patterns of beta, our intuitiveness becomes severely damaged. As you increase your theta brainwaves and your delta brainwaves, your intuition will increase and so will your ability to recognize the feelings in your “gut.” There are some disagreements as to whether or not the theta brainwave patterns are better for intuition vs. the delta brainwave patterns, but most research suggests that if you can become consciously aware in the delta brainwave state, you will have a nearly perfect sense of intuition.

Connecting with the spiritual body
Many consider the delta brainwave to bridge the conscious mind with higher planes of reality, the subconscious mind, and / or the unconscious mind. Advanced spiritual gurus have considered the lowest brainwave pattern, delta, one that connects their spirit and their body to a universal life energy. Becoming consciously aware of experiencing the delta brainwave frequencies has been associated with the deepest sense of spirituality, highest sense of internal awareness, and feeling directly connected to a Higher Power.

Paranormal Experiences
People are especially open to O.O.B.E.’s (Out Of Body Experiences), astral travel, connecting with spiritual beings (i.e. “spirit guides,” “angels,” etc.), E.S.P., and other phenomenon in the delta brainwave range. Though most paranormal and psychic experiences can be argued to be real or fake, there is evidence that most people tend to have them when their brain is producing higher than average amounts of delta, and /or theta brainwaves. Though spiritual experiences and phenomena are commonly experienced in the theta brainwave state, the delta brainwave state has been associated with many too!

Boosted immune system
Increasing your delta brainwaves can lead to a boosted immune system due to the fact that delta brainwaves are associated with age-reversal or slowing, the production of healthy hormones, and significantly decreased amounts of stress. Increasing your delta brainwaves can lead to a boosted immune system due to the fact that delta brainwaves are associated with healing and rejuvenation of the body. Stress and too much anxiety can do harm to the immune system by releasing harmful chemicals such as epinephrine (adrenaline) and too much of the hormone: cortisol, associated with the adrenaline release. The delta brainwave releases pleasant chemicals and neurotransmitters to help keep your immune system at arguably its highest rate of performance.

Problems associated with too many delta brainwaves:

Packing on excess “emotional baggage”
If you’ve ever been told that you worry too much about the emotions of others or literally “feel what others are feeling,” chances are good that you have too much delta. While some people may enjoy increased empathy, others may feel like they are too caught up in other people’s emotional lives. The delta brainwave can definitely make you pack on too many extra emotions if you aren’t prepared.

Extremely unfocused mind
Not everyone may particularly enjoy an increased amount of delta brainwaves in their waking E.E.G. The delta brainwave range has been linked to extremely unfocused, unconscious thinking, and ADD. The delta brainwave range can increase mental fogginess, dreaming, and forgetfulness. If you are already extremely unfocused, increasing your delta brainwaves isn’t recommended.

Extreme sleepiness
Since the delta brainwave pattern has been linked to the deepest stages of dreamless sleep, increasing this brainwave may make you feel more sleepy than you normally do. The delta brainwave is found in individuals that are sound asleep. Drowsiness and extreme sleepiness will occur if the delta brainwave is displayed while a person is awake. When increasing your delta brainwaves, it is extremely common to fall asleep as your brain is being trained. You will wake up feeling refreshed though. It is very difficult to stay aware in the delta state of consciousness unless you are advanced in the practice of meditation.

Because the brain is functioning at the slowest possible brainwave pattern, the central nervous system uses up virtually zero energy. All of the energy that you’ve accumulated throughout the day from eating food needs to be put to use somehow. Having too much delta brainwave activity allows your brain and CNS to get by with very little energy. Since the brain and CNS use less overall energy, the excess energy is expressed in some people through hyperactivity.

Healthy ways to increase delta brainwaves:

Brainwave entrainment
As I mention a lot, brainwave entrainment is great for fine tuning your state of consciousness and awareness. If you want to easily and naturally experience delta brainwaves, brainwave entrainment is an easy process that involves simply listening to a tone (stimulus) and your brainwaves will automatically, naturally shift in order to match the desired frequency associated with the acoustic tone. While delta brainwave states usually occur in deep sleep, it is possible to train yourself to remain awake while experiencing the delta brainwave.

Getting a good night’s sleep
Delta activity is present in stages 3 and 4 of sleep. Getting a good night’s sleep is important for staying healthy, keeping a healthy, powerful brain. Though delta brainwaves will not increase when you wake up the next day, they are highly prevalent in your brain while you are deeply asleep. Most non-dream, deep sleep is linked to an increase in delta brainwave activity, whereas dream-sleep is mostly linked to theta brainwave activity.

The goal of most types of meditation is to lower the brainwaves into the alpha-theta brainwave range. A very safe, healthy way to attempt to increase your delta brainwaves is to make the act of meditation a daily habit or start up a meditation routine. If you are already meditating, great - you’ll naturally increase your flexibility to travel through the alpha brainwave range, possibly through the theta brainwave range, and into the depths of the delta brainwave range.

Hypnosis / Self-hypnosis
The goal of all hypnosis and self-hypnosis programs is to target the lower brainwave ranges (i.e. alpha and theta) and implant new beliefs. If you practice frequent enough, and long enough, you may find that you are able to tap into your inner delta brainwave awareness.

Like meditation, yoga is yet another activity that promotes relaxation and wellbeing by shifting your brainwaves to the calming patterns of alpha, theta, and sometimes delta. The yogic phenomenon of suspended animation has been claimed to only take place in the delta brainwave range. Though there are many different types of yoga, if they are practiced correctly, they can be utilized to slow brainwaves to tap the delta awareness and insight from within.

Unhealthy ways to increase delta brainwaves:

Skipping sleep
Depriving yourself of a good night’s sleep or completely skipping sleep will increase the amount of cortisol (a hormone associated with stress and aging) and will flood your brain with a combination of unfocused brainwaves: mostly theta, some delta and in some cases high-beta. If you have ever pulled an “all nighter,” you’ll know that skipping sleep makes you feel extremely unfocused, dizzy, and confused. This is due to to a combination of unbalanced chemicals, hormones, and brainwaves. Not a wise idea to skip sleep to increase your delta brainwaves.

Final evaluation of delta brainwaves:

I personally think that delta brainwaves are very unique to experience and everyone has a different reaction. The deep spaced-out connection associated with delta activity can feel great. You should be the judge as to whether or not increasing delta is the brainwave you want to experiment with. If you are already experiencing many of the listed “benefits,” your delta brainwave could be within it’s healthiest range.

Are you already a mentally fogged person? If so, chances are good that your brain could be naturally producing some delta brainwave activity. However, most people do not have large amounts of the delta brainwave unless they are in the deepest sleep stages. If you are experiencing too many of the listed negative effects, you may want to consider speeding up your brainwaves into the beta range.
