Everybody has been in a situation where their lives were at risk in one way or another. Can you remember the feeling at that time? You felt stronger than usual, right? Your heart beat faster, you were faster, you thought faster.
During that time, you had thoughts on whether to fight or to run away from the situation. This is what we call the fight-or-flight reaction. This reaction is brought about by a release of the hormone epinephrine.
This hormone is produced by the medulla inside the adrenal gland. The adrenal gland releases the hormone which is called epinephrine together with other hormones. This epinephrine is also what we call the adrenaline.
You may have already heard about the words "adrenaline rush", which makes the person capable of doing the impossible. Epinephrine or adrenaline is a natural occuring hormone causing the heartbeat to speed up, strengthens heart contraction force, and widens airways for more oxygen to come in. Because of this, a person temporarily gets heightened senses. This makes the person strong enough to do things that can't be done under normal conditions.
People prone to severe allergic reactions often bring epinephrine injectables with them when traveling. Most of these people are prone to a severe allergic reaction called anaphylaxis. If a person has both asthma and allergy, the injectable epinephrine is very important. This enables them to cope up with severe allergic reaction and at the same time enables them to breathe easily; thus, preventing an allergy reaction and asthma to further develop.
Traveling patients are often advised by their doctors to always carry two injectable epinephrine just in case the other is lost.
