A person’s body releases the hormone adrenaline when they are frightened or emotionally unbalanced.
The heartbeat accelerates as soon as adrenaline reaches the heart, increasing the blood flow to the muscles.
As a result of the diaphragm and rib muscles contracting, adrenaline also quickens breathing.
Additionally, the adrenaline rush raises blood pressure and facilitates the blood’s ability to absorb more glucose.
All of these take place as a result of our body reacting to the release of adrenaline into our blood.
