Stay cool during crisis

Staying cool in a crisis might benefit heart health. A US study discovered that people who keep problems in perspective experience an increase in levels of 'good' high-density lipoprotein (HDL) cholesterol, which helps to keep arteries clear of fatty deposits. The research asked 716 men with an average age of 65 to rate how often they used certain coping strategies in stressful situations. After an overnight fast, their blood was tested for HDL and LDL (low-density lipoprotein) cholesterol.
It was expected that a hostile response to stress would raise levels of 'bad' LDL cholesterol, but these were unaffected. What the study did show was a positive conseguence of self-control, suggesting emotional stability has protective effects.
