The Speed of Sensation

A delicious bite of ice cream can suddenly turn into a jolt of pain if you have sensitive teeth. That’s because the human body is engineered to feel any pain fast. In fact, the entire process from nerve stimulation to actual sensation takes just milliseconds.

To understand how we experience sensation, check out how the brain registers pain by the numbers.

Eye icon

Up to 350x faster than the blink of an eye.

Sharp Pain vs Dull Pain

Interestingly, not all pain sensations travel at the same speed. 

Speedometer that reads 67 MPH

Sharper pains travel much faster due to the specialized nerves that are responsible for transmitting them to the brain.

Speedometer that reads 4.5 MPH

Dull pains are transmitted at a slower rate due to the different sets of nerves that are involved.
