The effects of stress are well reported in relation to many health conditions, for example, cardiovascular health. What has received less media attention are the effects of stress on brain health.
Stress begins in the brain. As information comes in through our ears and eyes it travels to several parts of the brain. When an individual perceives stress (anything from pain to a maths test) the body interprets and processes the threat in an area of the brain called the amygdala. From there the amygdala switches on two other systems – the hormone system and a branch of the nervous system called the sympathetic nervous system.
