Adrenaline in the body, what does it do?

Skydiving, ziplining, and swimming with sharks are activities that can release adrenaline, a hormone that prepares the body for action. When we’re excited or afraid, our bodies produce adrenaline which increases heart rate, blood pressure, and breathing rate. The hormone is produced in the medulla of the brain and in the central nervous system, and triggers the “fight, flight, or freeze” response by sending more oxygen and blood to our muscle groups. At the same time, the body’s pain receptors are temporarily reduced to allow us to react to the situation.

After an adrenaline rush, the body slowly returns to its normal state. To ease back from an adrenaline rush, taking deep breaths and getting fresh air can help calm unwanted anxiety. Some people actively seek out activities that release adrenaline, which is sometimes referred to as being an “adrenaline junkie.”

Epinephrine for anaphylaxis

In medicine, adrenaline is used to reverse the effects of anaphylaxis by constricting blood vessels and increasing blood pressure to decrease swelling. EpiPens, emergency devices that contain epinephrine (adrenaline), are prescribed after allergy and blood testing and should only be used under the direction of a healthcare professional. Unintentional injection of an EpiPen can cause dangerous side effects such as dangerously high blood pressure, stroke, or death. It’s important to stay informed about the proper use of EpiPens and to consult with a healthcare professional if you have any questions or concerns.
