I. Ultrasound impact
Dolphins use over 10,000 different sounds, including sounds at frequencies inaccessible to our hearing. Ultrasound is used by dolphins for both communication and navigation (returning in the form of a reflected sound, it gets into the inner ear through the hollow bones of the lower jaw, due to that a picture similar to an ultrasound scan is formed it is formed in the head of a dolphin).
During the cycle of inhalation and exhalation which occurs through a special opening on the dolphin’s head (which is called the breather), the air passes through the sound channels of various widths located behind the frontal bone of a dolphin. It has a concave shape, which allows ultrasound to focus better before passing through a special sound lens called “melon”, one that we usually take for the animal’s forehead. The jaw, or rostrum, is a kind of guideline for this ultrasound wave, and as a result of its impact the favorable chemical and electrical changes take place in the human’s brain and body. At the cellular level the metabolism between the cells of the human body improves; on neurological level the neural patency of the central nervous systems improves (new neural connections form faster, which positively affects the speed of learning new skills and improving the existing ones).
II. Psycho-emotional impact
Psycho-emotional state is a complex set of changes occurring in the body and psyche, including physiological arousal, feelings, cognitive processes, behavioral reactions to a situation perceived as important for a given person. It is a generalizing concept for all the experiences that arise in life, they help motivate a person, correct his behavior, affect his thinking.
During the psychocorrection sessions with the participation of dolphins, the following changes in the psycho-emotional state of the child occur:
a) Overcoming the stress – expanding the child’s living space due to the positive experience gained as a result of overcoming a stressful situation (which may be contact with a dolphin, absence of parents near him, and other related factors).
b) Improving mood – it is a consequence of the child’s adaptation to new conditions and is accompanied by positive changes in his emotional state, both before and during the session.
c) Increased motivation – not only to contact with the dolphin, but also to independent actions in general.
d) Increased playing activity. It is no secret that the main activity of children is the game. Thanks to activity in the game with dolphins, many children begin to play better outside of the session. The range of games is expanding, new elements of playing behavior appear, the independence and initiative of the child develop.
e) Interspecific communication. Due to the high playing activity of dolphins, a child can “plunge” into the world of marine life, which greatly improves his social and communication skills in the future.
III. Physiological impact
The physiological level includes factors that not only strengthen the body, improve blood circulation, normalize metabolism, but also increase tone of the central nervous system. They are:
a) Dynamic change of temperature – that is the process of descending into the water and getting out from it. It is a good start for further tempering of the body.
b) Increased physical activity – by increasing the number of movements performed both independently and with the help of a therapist.
c) Natural hydromassage – which occurs while swimming on dolphins, due to movements of the caudal fin and contractions of the muscles of the body of the dolphin.
