Stress

Question 1

What are the effects of immediate stress?

Answer 1

Stress activates the sympathetic nervous system (producing adrenaline and noradrenaline via SAM pathway)
High levels of adrenaline lead to:
- increased heart rate (takes a toll on heart health)
- vasoconstriction of vessels leads to higher blood presssure
- higher bp can dislodge plaques on the walls of vessels (atherosclerosis) which can lead to heart attack or stroke
