Contraindications and side effects

Post by Андрей Патрушев » Mon Mar 12, 2018 14:13

If You have an official diagnosis of epilepsy or other seizure activity, or was experience discomfort or spasms when You: looked at the surface of water, brilliant in the sun; walked through the woods and the sunlight was filtering through the branches of the trees meet, and likewise along the high fence with vertical bars; has driving at night or in a tunnel towards a bright light; during the computer game or movie with similar lighting effects; You classes with light and sound technology is definitely contraindicated.
Other contraindications, when a doctor's consultation, are: the presence of a pacemaker, cardiac arrhythmia, cerebrovascular disease, recent (1-2 months) head trauma, brain tumors (various etiologies), early (before 3 months) of pregnancy, the use of psychotropic drugs (within 4 hours before the session or on a regular basis).
the Use of drugs and alcohol is not compatible with the audiovisual stimulation of the brain.
Side effects of AVS
Hypnotic effect of light-sound stimulation has a tendency to enhance feelings regarding the use of this method. Thus, the unpleasant feelings will be further strengthened and can generate a strong emotional rejection.
Despite the fact that in most cases light & sound brain training is completely safe and can bring invaluable advantage, can take place side effects that, being unknown, is able to repel the user from further use of AVS:
1. Orthostatic Hypotension;
2. Headache associated with muscle tension;
3. Somatic shock;
4. Vascular headache;
5. Photoepilepsy;
6. Improving the functioning of the organs;
7. Activation of the traumatic memory.
8. Unusual sensations associated with deep relaxation and altered States.
9. Diffuse inhibition of the cerebral cortex.

1. Orthostatic Hypotension.
You can cite a fairly common example of orthostatic hypotension, when a person during deep sleep suddenly awakened by a phone call. Delirious man jumps up, he's dizzy and he falls on the floor (and sometimes getting seriously injured from a blow on the furniture).
From a physiological point of view, in a state of deep relaxation the heart beats very slowly and arteries have a low tone, so I can quickly provide blood to the brain with such a sharp force.
Because during meditation training relaxation can be even more profound than in natural sleep, after a sound and light session, still need some time to sit with a tall spine, making light exercise to normalize blood pressure.
If You are not in a hurry, you can just a few minutes to enjoy rest and tranquillity, making the suggestion that in this condition the most effective.
2. Headache associated with muscle tension.
Sometimes, especially after the first experience, after meditation training, the person may experience headache. Most often this pain is associated with the settings too high led brightness and sound volume in the headphones. Because of too high brightness eyelids begin to tremble with each light flash.
The second reason is the need for all and Sundry to control it.
This pain is often characterized by strain and irritation in the forehead (and sometimes temples). On entering the trance state the muscles relax. Thus, the sooner a person enters a trance state, the less likely a headache after the session. When you reach a certain experience headache after the session also becomes less likely.
This type of headache can easily be avoided by choosing a comfortable brightness and volume. Red light increases the risk of headaches, white, green, and blue, on the contrary, reduce.
Sometimes headache occurs as a result of muscle tension in the neck and shoulder girdle, associated with an increased need for self-control. Such people, instead relax and let the total flow of images that arise during a light and sound session, trying to track every flash of the LEDs, excessive straining. Also, they largely oppose a loss of control over the surrounding reality, and feeling that the mind begins to "float" have been making significant efforts and tension, to prevent this phenomenon.
Unfortunately, such people often refuse further training and experience relaxation and ability to let go of excessive self-control. But they constitute the first risk of cardiovascular diseases.
AVS has its history since the 50-ies of the last century. It is a completely safe method that could be of great benefit, the one who uses it. So if you are afraid to lose control, just relax and allow yourself to gain new experience. The maximum that can happen – you fall asleep. Recommend the first experiments with the use of ABC to make there, where you feel safe.
3. Systemic shock.
Systemic shock occurs when someone in a state of deep trance (meditative, hypnotic subjects, users AVS), something scared (loud sharp sound, touch). Users of AVS in addition may experience mild systemic shock when sudden changes of stimulation parameters, including from the sharp cutoff of light and sound at the end of the session. All modern mindmachine have the option of smooth on / off of light and sound at the beginning and at the end of the session.
The standard situation occurs with Pets, when there suddenly the dog barks or the cat suddenly vspugnet on your lap (on his chest). Also try to keep Pets can not hurt You during the session. It is useful to warn you and your household, so they do not touch You or talked to You until the session is over.
Some semblance of physical shock may experience people suffering from need to overcontrol when they suddenly realize that they are in an altered state of consciousness. For such people, it may be advisable to engage in an environment that they considered safe, and at the same time to focus on peaceful thoughts about something pleasant.
4. Vascular headache.
In most cases, this pain can take place only after some of the first experiments with light and sound devices. Some people may experience a mild headache after each application of AVS. If headaches are severe and prolonged, it is reasonable to stop further audio-visual stimulation.
We can distinguish two types:
A) Parasympathetic. The appearance of this pain is most likely in individuals who are in a constant state of stress, one of the signs of which are constantly cold hands and feet. As in the state of deep meditation during a meditation session is significant, the increase in temperature of the hands and feet (e.g., from 23.8°C to 32.2°C). Thus, the arteries, used to be constantly in a state of high tone, while the relaxation can stimulate the onset of a headache.
The same pain (not always and not all) can occur with hypotension, because the AVS-stimulation in the range of alpha-theta rhythms tends to lower blood pressure. Although long-term (from 2 weeks to 3 months) of stimulation in the alpha range low blood pressure usually returns to normal, but not everyone can withstand. So when the pain is associated with low pressure, we recommend upgrading to the beta session ("E"), which have a tendency to a slight increase in pressure. Of course, hypertension session "E" is contraindicated.
B) Increased cerebral circulation. In 1992, using the methods of magnetic resonance and positron emission tomography have installed the enhancement of cerebral circulation by 50% in videoarticle during visual stimulation. Although the improvement of cerebral circulation can significantly relieve suffering in the presence of the syndromes of reduced attention and PMS, migraine and other related disorders of cerebral circulation disease, however, increased cerebral blood circulation, probably also can be a cause of headache.
5. Photoepilepsy.
By itself, meditation training promotes neither the emergence nor the development of this disease. He only can be a "trigger" for the attack, in the presence of the disease.
According to medical statistics, in our population, to 24, a single man of the four thousand with the risk of photoepilation, and one person in ten thousand, after 24 years.
Most people tend to photoepilation, never in my life had seizures, or have experienced a seizure only once, and then subconsciously avoided the conditions under which it is possible to repeat. Typically, these conditions can be: looking at the sun glare on the water, walking through the woods when forward movement of the sunlight streaming through the trees (high fence made of vertical rods), the drive through the night-lit city or through a tunnel with bright lights, computer games or movies with similar effects. However, most attacks happen when watching TV or computer games. By themselves, the attacks are not dangerous. Dangerous only possible injury in the fall.
Photosensitive people are more likely to experience a seizure during photostimulation with my eyes closed than open because the eyelids play a role of a lens, involving the perception of more nerve endings.
Most researchers of photoepilation inclined to think that the red light and the pulsation frequency of about 15Hz more likely to cause seizures than other colors and frequency. The most secure in this regard is the blue light. Also, in laboratory conditions, it was found that the presence of blue light is able to completely suppress the ability of the red to cause seizures.
Some researchers believe that pulsating sound, under certain conditions, probably also can cause epileptic seizures, but experimentally it is not confirmed. On the contrary, there are some data on the significant reduction in the frequency and intensity of attacks of ordinary epilepsy in the regular classroom with certain audio programs ("Focus 10" the Monroe Institute and "Healing").
6. Improving the functioning of the organs.
Currently, dysfunction of internal organs as a result of stress, reliably and repeatedly documented, and no one doubt.
When a person begins to apply on a regular basis sound and light training, the result is deep relaxation, a violation of the functioning of the organs disappear.
What is the problem? The problem may be associated with the dosage of drugs that people used before the start of classes ABC. There are repeated evidences of improvement in the functioning of the pancreas and thyroid glands and associated risk of drug overdose, which usually continue to take the usual quantities.
Therefore, people began to regularly engage in ABC and with any chronic disease, it is possible to strongly suggest that increased medical surveillance.
7. Emotional activation of a traumatic memory.
Some of us have very painful memories about traumatic events that occurred in the past, the memory of which in varying degrees had been pushed into the subconscious. However, this memory constantly haunts people for life, manifesting itself in irrational outbursts of anger (or even violence), irrational fears, sexual dysfunctions, low self-esteem.
Certain smells, sounds, touch, taste sensations associated with these events, can suddenly resurrect that memory, causing vivid hallucinations. Meditative practices and hypnosis are also able to resurrect repressed memory in the mind. Same goes for light-sound brain training. Due to the deep trance States that occur during meditation session, this repressed memory is suddenly and rudely break into consciousness, causing very strong emotions.
And although these deep trance States can do much to assist in the processing and integration of traumatic memory, however, it would be wise to conduct this work in the presence of a qualified therapist. Especially if you have a formal diagnosis of PTSD.
Our body also stores the memory of trauma, so sometimes, during the AVS session, you may experience pain (or, indeed, any other – cold, fever, itching, pressure, etc.) and discomfort at the sites of former fractures, severe bruises and injuries (as well as phantom pain in the missing limb). But it usually passes quickly. Method AVS is also very effective for getting rid of phantom pain.
8. Unusual sensations associated with deep relaxation and altered States.
When doing AVS, it is possible to obtain various effects such as unusual sensations. Due to the synchronization of bioelectrical brain activity with light and sound rhythms designed for relaxation, the body begins to deeply relax (sometimes deeper than regular sleep).
At certain stages of relaxation every person experience various unusual, sometimes regard them as unpleasant, feelings. For example, the person can hear your own snoring, appear itching, tickling (tingling), drawing, etc. sensations in various parts of the body, sensations of falling (flying) somewhere, "tremors", or(and) pulsation in different parts of the body, feeling the strong heat or cold.
The man begins to hear and feel the beats of their own hearts (which is often mistakenly perceived as palpitations and accompanied by fright), and the sounds in the room around him.
This means that You have reached a fairly deep degree of relaxation and a few classes You will have to get used to all these sensations to move on. Sometimes the aggravation of all (or some) of sensory systems takes place some time after sound and light stimulation.
In the relaxed alpha state, a person begins to feel all of the pain zones and points in the body ("pain that hurts"). This does not mean that ABC has caused You the pain (a very common conclusion ), which means that manifested some kind of your old (or fresh) somatic problem. In this case mindmachine acts only as a diagnostic tool. Often, with regular practice alpha relaxation happens self-treatment of most problems that are often associated with excessive stress.
9. Diffuse inhibition of the cerebral cortex.
Effective lessons with mindmachine very individual. Recommended time of 15-20 minutes at a time, with a break between the times at least 3 hours. In General, after 45 minutes, the brain refuses to act on any incentives and you may have unpleasant (for most people) stunned asleep, sometimes with palpitations, the cause of which is the so-called diffuse inhibition of the cerebral cortex.
But for some people even a 10 minute stimulation (rapid rhythms of beta-band) may lead to razlitom braking, therefore, do not get involved in long classes or(and) to put successively the different orientation of the session - no good it can not lead. In most mindmachine provides specifically for the possibility of reducing the duration of the session two times (in increments of B1/8). The same applies to too high of a volume and brightness. Recommended interval between sessions – at least three hours.
Remember - for sound and light stimulation, MORE is NOT BETTER in all respects. First of all, listen to your feelings.<
