2. Brain function
Studies have shown that the development of some phobias may be linked to brain function. This applies to all phobias rather than a fear of long words specifically. Those who are afraid of heights and spiders have also displayed some behavior leading psychologists to believe that their brain function may be playing a role in their irrational fear. There are various things that could change how your brain functions.
For instance, stimulants and opioids can alter the way that your brain functions based on some research conducted on drug abusers. Those who took heroin, meth, and cocaine on a regular basis displayed aberrations in the way that their brain is wired. This leads some doctors to believe that drug use may be a major factor in the development of various phobias including the fear for long words. If you want to avoid a fear of long words then heed Nancy Reagan’s advice and just say no.
