Adrenaline rush
Adrenaline rush, also called adrenaline crash, and adrenaline surge is a physiological state described by some people with ME/CFS and Long COVID.
Although the word "adrenaline" is used by patients to describe the phenomenon, it is unknown if the release of adrenaline (epinephrine) is the cause of the phenomenon, which is described as being characterised by:[1][2][3]
- A temporary increase in energy levels compared to baseline
- Inability to rest and anxiety
- Lessening of some symptoms
- Autonomic dysfunction (fast heart rate, jittering / muscle spasms, low heart rate variability etc.)
Prevalence[edit | edit source]
Symptom recognition[edit | edit source]
An adrenaline rush is similar to the state of being "wired but tired", however tiredness is not necessarily a feature of an adrenaline rush.[4] It is not to be confused with a panic attack, as a panic attack has a psychological cause, whilst an adrenaline rush has an organic cause.[5]

Possible causes[edit | edit source]
Adrenaline rushes have been described in some patients during and after overexertion, but before post-exertional malaise (or a crash) begins.[1][2]
