A list of the symptoms should include:
• Increased heartrate
• Rapid, shallow breathing
• Muscle contraction
• Tunnel vision
• Heightened sensitivity
• Increased blood viscosity
• Suppression of the pain response
• Suppression of the immune system
• Suppression of the digestive system
• Dilation of the pupils
• Dilation of the blood vessels
• Reduction in prefrontal cortex activity (temporo-hypofrontality)
In the short term, this is good for us. In the short term, these things help us to evade danger and win combative situations. Increased muscle tension makes us stronger. Increased blood viscosity makes our blood more likely to clot in case of an injury. Dilated pupils let more light in to improve our vision. Suppression of secondary functions means that more blood can be sent to the muscles and the brain. Reduced pain means we can carry on fighting or running despite injury.
