Fear is one such emotion that is pre-programmed into all animals and people as an instinctual response to potential danger.                  As for   what is fear biologically speaking, when a person experiences fear, certain areas in their brain such as the amygdala and the hypothalamus are immediately activated and appear to control the first physical response to fear. Chemicals such as adrenaline and the stress hormone cortisol are released into the blood stream causing certain physical reactions such as:                 <ul> <li data-xf-list-type="ul">Rapid heart rate</li> <li data-xf-list-type="ul">Increased blood pressure</li> <li data-xf-list-type="ul">Tightening of muscles</li> <li data-xf-list-type="ul">Sharpened or redirected senses</li> <li data-xf-list-type="ul">Dilation of the pupils (to let in more light)</li> <li data-xf-list-type="ul">Increased sweating</li> </ul>                 People who have experienced this will often remember the moment when disaster stuck and how time seemed to slow down. They knew exactly what to do without consciously thinking about it, they had great strength (some have even been able to lift a car to save their trapped child) and they felt no pain. All these are protective mechanisms to increase our chances of survival.                  There are numerous  causes of fear. Some are better known than others such as fear of flying or Aviophobia, fear of spyders-Arachnephobia, and fear of confined spaces-Claustrophobia. Others types of fear not so well known are fear of mirrors-Catoptrophobia, and fear of hair-Chaetophobia. Fear of being tickled by feathers-Pteronophobia, and Papyrophobia or fear of paper are yet other not so well known causes of fear. Still new causes of fear are being diagnosed.</blockquote>
