Let’s assume you have a problem with one of your senses. Who would you go to? ENTs deal with your ears, nose, and throat (btw they are actually called Otolaryngologists ). Ophthalmologists deal with your sense of sight. If you have problems with hearing, smell, taste, or sight, you just go to one of these common doctors.
But what if your sense of touch is having an issue? what type of doctor do you go to?You will have to go see a neurologist or even a brain surgeon. There is no one who specializes just in your sense of touch—maybe because we tend to believe that touch is the least useful of the senses.
Here are some facts about the sense of touch that are really surprising
1. Influences Decisions
Most people probably think they’re in control of their thoughts and decisions and even brag about it . It’s called free will, and it’s kind of a big deal. But are you sure that your honest, objective decisions are truly your own?
Leading research says that you may be influenced by the slightest things without consciously realizing it. Researchers ran groups of volunteers through a variety of scenarios to test the idea of scaffolding, in which “humans learn to grasp abstract mental concepts by relying upon physical sensations.”
Subjects evaluating resumes on heavy clipboards rated them as more serious than resumes on light clipboards. In a different test, subjects in hard seats were less likely to negotiate price than people in softer chairs. People who handled rough, sandpaper-textured puzzle pieces rated social interactions more harshly than others.
So your physical surroundings affect your opinions because of our sense of touch
2. Touch Affects Taste
Now this is weird . How can touch affect taste. I know you thought that when you read this point. Everyone has different tastes, but there are at least four flavors that are universally accepted: sweet, bitter, sour and salty. Although taste scientists argue over whether to add new flavors to the list, most agree that the burn you feel from hot peppers or the coolness of mint are not flavors. Those sensations are not created from taste buds but from touch receptors.!!
3.Touch Affects The Sexes Differently
Even a slight touch can be a powerful thing. Studies show that being touched in a friendly, nonsexual way can cause physical and psychological changes. In one study, it was found that people become more confident when they’re touched by a woman. Furthermore, when a man is touched by a woman—like a pat on the back—he’s willing to take more risks.
The reason a woman’s touch makes people more confident is probably because babies are constantly being touched by their mothers to encourage them. Having physical contact with a woman simulates this feeling. The study showed that handshakes don’t produce as much of an effect and being touched by a man doesn’t make anyone more secure.
However, a different study showed that a woman’s temperature can rise by almost a full degree if she is touched by a man. The face and chest skin are the areas that get the warmest. One-quarter of the test subjects didn’t even realize that they were getting excited. Men get warmer, too, but by a much smaller degree.
So, women, feel free to go touch anyone you want. Men . . . be careful who you touch.
4. It’s Incredibly Sensitive
Senses like sight and hearing are considered fundamentally important to most of us, and they’re easy to measure. If you have an exceptional sense of smell or taste, you can use these endowments to make a career in the perfume or food industries.
However, touch sensitivity has normally been ignored. it seems like the least of the five senses,but the predominance of touch screens on our electronic devices is finally getting touch some attention.
To build a better touch screen, you have to know how sensitive our sense of touch is. Swedish scientists have now shown that “the human finger can discriminate between surfaces patterned with ridges as small as 13 nanometers in amplitude.” That’s incredibly sensitive. A nanometer is one-thousandth of a micrometer. A micrometer is one-thousandth of a millimeter, or roughly 0.00004 inches.So dont discount your sense of touch
5.Touch Leads To Success
Touch is the first sense of humans . It’s the one most developed in babies, so it should follow that touch is very important. In fact, it’s so important that teams that are more “touchy-feely” tend to have more success.
While previous studies have shown that emotion can be communicated through touch, no one had ever looked at how touch influences performance. A study of NBA players showed that teams who engage in more “fist bumps, high fives, chest bumps, leaping shoulder bumps, chest punches, head slaps, head grabs, low fives, high tens, full hugs, half hugs, and team huddles” perform better individually and as a team.
Researchers watched an entire season of basketball and recorded every time that teammates made any intentional physical contact. The results showed that touchy teams tend to be more cooperative and more successful.
6.Touch is Related To Hearing
Hearing has been studied a lot as there are lot of instances of hearing loss . With the advancements in DNA sequencing in recent years, science has found over 70 genes that can cause deafness or hearing loss. But not one gene has ever been found to influence the sense of touch, though.
Researchers in Berlin wanted to know if there was a genetic relationship between hearing and touch as they operate in a similar way. They’re the only two senses that “rely on the transformation of mechanical force into electrical signals.”
Testing on subjects, including identical and fraternal twins, showed a correlation between loss of touch and loss of hearing. Furthermore, people with Usher syndrome, which can cause deafness and blindness, had a poor sense of touch as well.
This provided evidence that a poor sense of touch can be an inheritable condition and that hearing and touch related through evolution. It should be stated, though, that not everyone with hearing loss has a poor sense touch.
7. Science Can’t Turn It Off
As stated earlier Your sense of touch is a complex phenomenon that is not entirely understood. For instance, when someone’s fingers are anesthetized, people are still able to use their hands. You shouldn’t be able to feel anything, but research has shown that people can still feel fine surface detail.
If medical science has deadened the nerves in your hand, then what is giving you a sense of touch?
The answer may be that vibrations from touch travel farther up your arm. If your hand has been rendered numb by painkillers, could it be that parts of the hand near the wrist are receiving vibrations that are interpreted as touch?
Researchers suspect that the hand can interpret vibrations just like the ear does. Currently, scientists are studying these vibrations to better understand the mechanics involved. Advancement in this field might help us to make more sensitive robots, better prosthetics, and more realistic virtual reality.
8. Women Have Better Touch
Women typically have smaller hands than men. Researchers studying the sense of touch showed that smaller hands are more sensitive than larger ones. “Tinier digits likely have more closely spaced sensory receptors.”
Our fingers are packed with sweat pores, which are surrounded by different types of sensory receptors. Some respond to indentations while others respond to vibrations.
Adults tend to have the same number of these receptors regardless of hand size. Therefore, people with petite hands will have these sensory receptors packed closer together, giving them a finer sense of touch. This may mean that people with small hands are better at touch-reliant occupations like surgery or embroidery.
The study is ongoing and looking to determine if children have even more sensitive touch.
9. Inattentional Numbness
According to researchers, the best time to pick someone’s pocket is when they’re visually preoccupied—like if they’re reading departure times for a train or plane. In one study, “touch sensitivity was reduced when people carried out the more complex visual search task.”
It’s called inattentional numbness. Research done at Royal Holloway, University of London, offers the first evidence that looking too hard at something makes you less sensitive to touch. It was already well-known that people can miss visual or auditory stimuli if they are paying attention to something else. But tactile information had never been tested this way.
The fingerprints have always been a mystery. Most animals don’t have them, so why do we?
For years, the most widely held idea was that they increased grip strength. But recent tests say that this is probably not the case. In fact, fingerprints may be worse for gripping in some instances than smooth skin.
So what’s their purpose?
Georges Debregeas and his team at the University of Paris have tested fingerprints in another way. They determined that fingerprints amplify our sense of touch instead of amplifying friction for grip.
The receptors for touch are deep inside our skin. Their tests show that fingerprints not only help to convey signals to our nerves but also filter out all the unimportant background vibrations—everything above and below 250 hertz—which is like white noise in a tactile sense.
Instead of the brain taking in everything and trying to make sense of all the tangled sensations, our bodies may have built-in filters and amplifiers to give it only what it needs.
