(ELI5) If a person is having anaphylactic reaction, could making them bungee jump have the same effect as an EpiPen?

Because wouldn't an action like bungee jumping provide a large amount of adrenaline pumping through the body? Isn't that the whole purpose of an EpiPen? To provide extra adrenaline to the body?

I would doubt it. One of the text book symptoms of anaphylaxis is a "feeling of impending doom". There are not many conditions in medical literature that are described as having a "feeling of impending doom." The stress of such an event would likely cause a massive sympathetic response as your body releases as much epinephrine and norepinephrine it possible can. The fact you're getting hypotensive and going into circulatory shock means the histamines are overwhelming your bodys maximum ability to defend itself through epinephrine release. Epinephrine injections are kind of like you secretly supplying weapons to your adrenal glands so they can tip the scales of the war on histamine.
