Edit: gag reflex
In: Biology
Assuming you meant gag, it isn’t. This is a common misconception, and although you may notice your gag reflex is suppressed upon squeezing your thumb, there is not physiological sensation responsible.
It’s likely the placebo effect, or basically a mental trick you’re playing on yourself. If you squeeze your thumb thinking “I won’t gag because I’m not supposed to” you might be inadvertently relaxing your muscles in the throat.
