Pyrophobia

[2] The most common cause of pyrophobia is that fire poses a potential threat to life safety (which is identical in animals).

However, people who are intensely pyrophobic cannot even get close to or tolerate even a small controlled fire, such as fireplace, bonfire or lit candle.

This method involves showing patients fires in order of increasing size, from a lit cigarette up to a stove or grill flame.

Another method of treatment is talk therapy, in which a patient tells a therapist about the cause of this fear.

People can relieve pyrophobia by interacting with other pyrophobes to share their experiences that caused fear.
