Adrenaline (epinephrine) is a hormone produced by the adrenal glands that is released into the bloodstream as part of the "fight-or-flight" response to stressful situations. People with social anxiety disorder (SAD) may experience the effects of adrenaline when in social or performance situations.
When adrenaline is released, heart rate and blood pressure increase, there is a rise in oxygen to the brain and muscles, and blood flow is increased to the major muscle groups to prepare the body for action.
Adrenaline is also available as a medication used to manage severe allergic reactions.
Also Known As: Epinephrine
