一項對人類大腦裡一個細小部位的最新研究報告幫我們更近一步地理解瞭人類情緒變化與心血管疾病之間的聯系。這項研究說減輕壓力不僅可以改善人們的心理健康狀態，還有助於降低心臟疾病的發生機率。請聽以下報道。
The study lead by researchers at Massachusetts General Hospital and Harvard Medical School measured the effect of stress on 300 people over nearly four years.
Scientists use scans to monitor a tiny area of the brain called the amygdala which processes emotions such as fear and anger, they found for the first time in studying humans that higher levels of activities in the amygdala were linked with greater activities in bone marrow and inflammations in the arteries.
They suggested the amygdala tells bone marrow to produce extra white blood cells, which cause arteries to develop blockages and to become inflamed.
