Do you feel dizzy, have a fast heartbeat, nausea, and dry heaves after using a computer for a long time? What is the reason?

Long-term facing the computer will often have dizziness, nausea and motion sickness, seasickness, airsickness is basically the same reason, the medical term "motion sickness".

Human beings acquire information about the external environment through hearing, sight, and touch. After a long period of evolution, the various sense organs of human beings are highly coordinated and cooperative. For example, in the inner ear, there is an organ called the "vestibular apparatus", which is responsible for sensing the balance of the body, such as the direction of movement and acceleration of the human body.

The very real images on a computer screen make us feel like we're really moving, and these sensations come from vision. There are also specialized optic nerves in the eyes that sense movement. These motion sensing organs are very sensitive, and they transmit information about the motion they feel to the nerve centers, which control the body's ability to respond appropriately to the effects of motion on the body.

Because the muscles of the body and the tissues of the brain that are responsible for the movement part have not sent the body movement instructions, that is to say, the brain receives the movement signals from the optic nerve and at the same time receives the information that the body is not in motion. It causes the brain to be conflicted and thus unable to process it. The general instinct is to process this confusion as poisoning, and the stomach will initiate the elimination response, which is the feeling of nausea.

Methods of elimination:

1, in front of the computer should not be operated for too long, keep ventilation, air flow. Feel uncomfortable immediately stop, go out and exercise.

2, eat plums or motion sickness pills to reduce stomach discomfort nausea symptoms.

3, usually ensure sufficient sleep.

4, with the computer before the diet should be seventy-eight percent full.

5, have a computer before eating less greasy food.

6, I personally experience, adhere to the above points, often practicing will be a fundamental solution to the symptoms of dizziness and nausea in the face of the computer, by the way, but also to solve the symptoms of motion sickness, seasickness, airsickness and so on.
