Catecholamines are small molecules made by nerve tissue, the brain and the adrenal glands.
The main catecholamines are dopamine, noradrenaline and adrenaline.
Catecholamines help the body respond to stress or fright and prepare the body for "fight-or-flight" reactions by increasing the heart rate, blood pressure, breathing rate, muscle strength and mental alertness. They also lower the amount of blood going to the skin and increase blood serving the major organs, such as the brain, heart and kidneys.

Noradrenaline is produced naturally by the body and is often referred to as a 'fight or flight' chemical, as it is responsible for the body's reaction to stressful situations, increasing alertness and reaction time.
The release of noradrenaline causes an increased heart rate, increased blood pressure, widening of pupils and widening of air passages in the lungs. Noradrenaline also narrows the blood vessels in the extremities, which redirects blood to essential organs such as the heart and brain.
Adrenaline is a hormone released from the adrenal glands, involved in the body's fight or flight response. When the body is faced with a stressful or dangerous situation, adrenaline triggers the contraction of the blood vessels, to re-direct blood towards the major muscle groups including the lungs and heart. The body's ability to feel pain also decreases as a result of adrenaline. After the stress has subsided, the effects of adrenaline can last for up to an hour.
An overproduction of adrenaline is very common as most people are exposed to stressful situations on occasion. Symptoms of adrenaline release include a rapid heartbeat, high blood pressure, anxiety and excessive sweating. This release is a normal bodily response, intended to help respond quickly to a stressful situation.
Medical conditions that cause an overproduction of adrenaline are rare, but an adrenal tumour (pheochromocytoma) can cause an increase in adrenalin levels.
Dopamine is a neurotransmitter, responsible for the transmission of signals between nerve cells in the brain involved in many different processes including working memory, mood and movement.
