Carbon dioxide helps blood move throughout your body. So when your body doesn't have enough Co2, blood flows slower. In order to get blood flowing faster, your heart needs to beat faster and do more work, and irregular heart beat is the result. Hyperventilation also causes many other symptoms in those with anxiety.
Outline of science fiction. Science fiction â a genre of fiction dealing with the impact of imagined innovations in science or technology, often in a futuristic setting. Exploring the consequences of such innovations is the traditional purpose of science fiction, making it a literature of ideas.
The one defining(-ish, definitions differ) trait of Science Fiction is that there is technology that doesn't exist in the time period the story is written in. Consider 20,000 Leagues Under the Sea. The story was written in a time when submarines were still at the prototype stage, so 20,000 Leagues Under the Sea falls within the boundaries of Science Fiction. However, Science Fiction is as much a genre as a setting. Often, the technology is a means to explore a concept, and the story could be a detective story focusing on how advanced technology affects crime and policing.
