Which senses adapt quickly

When you first walk through the door, the delicious smell of garlic and tomatoes is almost overwhelming. You sit down to wait for a table, and after a few minutes, the scents begin to dissipate until you barely notice them. This is an example of sensory adaptation. Sensory adaptation is a reduction in sensitivity to a stimulus after constant exposure to it.

While sensory adaptation reduces our awareness of a constant stimulus, it helps free up our attention and resources to attend to other stimuli in the environment around us.

All five of our senses can experience sensory adaptation. Our senses are constantly adjusting to what's around us, as well as to us individually and what we are experiencing, such as aging or disease. Just imagine what it would be like if you didn't experience sensory adaptation.

You might find yourself overwhelmed by the pungent smell of onions coming from the kitchen or the blare of the television from the living room. Since constant exposure to a sensory stimulus reduces our sensitivity to it, we are able to shift our attention to other things in our environment rather than focusing on one overwhelming stimulus.

Here are some more examples of sensory adaptation in different senses. Even hand-eye coordination adjusts when necessary.

For instance, if you put on goggles that make everything appear to be a little off and you try to throw a ball at an object, eventually your sensory adaptation will take over and you'll adjust enough to be able to hit it.

If you've heard the term "nose blind," you've heard of sensory adaption; it's the same thing. But it's different from anosmia, or the inability to smell.

You also might notice that when you're away from a smell or a sound for a while, such as when you go on vacation and then return to your home, you notice it again.

Individuals adapt to the noise within their environment. For those who live in an area with continuous traffic, their ears adapt to the constant sound until they no longer hear the noise of the traffic. With louder sounds, such as a rock band playing while entering a nightclub, the muscle attached to the inner ear bone contracts, reducing the sound vibration transmission.

This decreases the vibrations to the inner ear, thereby adjusting to the noise level. Those who smoke tobacco do not notice the smell of cigarettes. Nonsmokers can usually smell the cigarette odor intensely and, if in the presence of a smoker, can smell it not only in the smoker's presence but will continue to smell the odor on their clothes, hair and other items long after the two have parted.

This same adaptation happens when wearing perfume or cologne: Within an hour of applying the fragrance, the wearer no longer smells the scent. The feeling of hot and cold is an adaptation to the sensation of touch.

A primary example is how quickly our bodies adjust to the water temperature when taking a bath. The bathwater may feel extremely hot when entering the tub; however, within minutes the water may feel cool to the touch.

The water temperature has not changed significantly; our bodies have adapted to the temperature. The taste buds in our mouth play a critical role during eating.
