The virtual reality is different from the real
Virtual reality - a world created by technical means in which people are able to sense a condition close to real. In virtual reality, man acts on objects by the laws of physics, but it can also be something that is impossible in the real world: to fly, to interact with any objects and creatures travel the fictional routes. Virtual reality creates an artificial world.
If the "real reality" - a familiar world around us, the virtual reality - it is space that is completely generated using computer graphics. Thus, in a virtual reality can be anything - from the observation of the dinosaurs to the shooter in the XXXI century.

What happens to a person with full immersion in VR
Virtual sense of interference depends on the degree of immersion. It is created through human senses: sight, hearing, smell, touch.
Sudden perception of themselves in an unfamiliar environment is at the same time delight, curiosity and sense of sleep. Virtual reality develops spatial thinking. It helps quite quickly get used to the artificial environment. The user starts to navigate in the new space and the assignments.

How to find a VR may have an impact on the body and the brain
Immersion in VR can cause dizziness and nausea, it warned the creators of helmets. Basically, the negative effects caused by the use of optimized enough for a game of computers. Poor equipment is not able to give a high quality image with a stable frame rate of at least 90 per second.
Problems may also occur when the user's head turns. The picture does not manage the movements of a person can start a headache. Vestibular system perceives it as a poisoning or exposure to extreme intoxication.
The most famous long stay in VR made Derek Westerman from the US. Age spent in the virtual reality 25 hours. To achieve the record, he chose HTC Vive helmet and application Tilt Brush, to draw three-dimensional images in three-dimensional space. Tilt Brush forces the user to be active and mobile to create new images while staying in virtuality. After 17 hours in VR Derek vomited. 25 hours VR Derek Westerman put in the Guinness Book of Records.
VR is not clearly regulated limitations. People with weak vestibular system should be used less frequently the rest of VR. At risk are also people with epilepsy and visual impairments.

"It has been proven that the effects of human immersion in a stressful situation is really significant and comparable in strength to psychological trainings. However, this effect is unstable and fades away quickly enough (2-3 months after the cessation of training). The researchers attribute this to the fact that the brain understands that everything that happened in the virtual environment was not real. Therefore, even with the modern possibilities of computer graphics and modeling of the barrier between the real and the virtual world is saved ", - says Anastasia.
How does dependence on VR and how to avoid it
Dependence on the immersion in VR is compared to gambling. People prefer the artificial world of the living to communicate with people, and the virtual world is replacing the real one. In many countries to solve the problem according to the virtual world create specialized rehabilitation centers.
In the case of VR everything depends on the quality of content. In the mobile version, it is not so good that you would rather run home and put on a VR helmet.

Set an alarm clock, to register in the automatic shutdown system after a certain period of time. Or ask a friend, girlfriend, mum to come in a couple of hours and pull out of the VR.
