Mature Natural Thumbs

For some adults who suck their thumbs, stress reduction and alleviation of symptoms stemming from anxiety may be a significant benefit. No other benefits have been identified in either research or anecdotally.

Some adults have reported that they were able to stop sucking their thumbs by making a decision to do so and sticking to it. This may not work for everyone, especially if the behavior has become a long-term or subconscious habit.

Humans are unusual animals by any stretch of the imagination. Our special anatomy and abilities, such as big brains and opposable thumbs, have enabled us to change our world dramatically and even launch off the planet. There are also odd things about us that are, well, just special compared with the rest of the animal kingdom. So what exactly makes us so special? Some things we take for granted might surprise you.

Our long thumbs and their ability to easily touch other fingers helps us firmly grasp and manipulate objects. We also have fine muscle control, meaning we can do wildly different activities with our hands, such as throw a curveball or hold a pen to sign our names, according to the AMNH.

Humans must remain in the care of their parents for much longer than other living primates. For instance, humans take nearly twice as long as chimpanzees to mature, and it looks like our ancient human relatives, such as the 3.2 million-year-old australopithecine Lucy and a 1.6 million-year-old Homo erectus boy, reached adulthood faster than modern humans do, Science magazine reported (opens in new tab).

The question then is why do modern humans take so long to mature, when it might make more evolutionary sense to grow as fast as possible to have more offspring? The explanation may be our large brains, especially its high number of cortical neurons; other animals with large numbers of neurons in the cerebral cortex, such as some birds and mammals, also have long childhoods and extensive longevity, a 2018 study in the Journal of Comparative Neurology (opens in new tab) found.

"It makes sense that the more neurons you have in the cortex, the longer it should take a species to reach that point where it's not only physiologically mature, but also mentally capable of being independent," Suzana Herculano-Houzel, author of the 2018 study and an associate professor of psychology at Vanderbilt University, said in a statement (opens in new tab). "The delay also gives those species with more cortical neurons more time to learn from experience, as they interact with the environment."

Several treatment options have been proposed for thumb sucking. Treatment options can range from counseling to the patient and parent, using different mouth appliances, implementing behavior-modification techniques such as advice and incentives for changing behavior, and applying a nasty tasting substance to the children's thumbs myofunctional therapy or combinations of these treatments. A Cochrane review done in 2015 showed that using an orthodontic brace or a psychological intervention (such as the use of positive or negative reinforcement) or both was more likely to lead to cessation of the habit than no treatment.[1][5]

Such peer pressure should make the older child stop sucking his thumb soon enough. At least during the day when the child is in school or on the playground. The older child may however, still continue to suck his thumb in his sleep, just as he did when he was a baby. Some older children may manage to stop sucking their thumbs most of the time, but resume the habit when they are under stress.

Infant thumb sucking is a natural reflex, performed repetitively, automatically, and without nutritional value. It is, however, a palliative act, making the infant feel happy and secure.

Thumb sucking is relaxing and may help induce sleep, explaining why children suck thumbs as they fall asleep. Of Interest, sonograms of pregnant women have noted fetal thumb sucking in the womb. It is postulated that the fetal thumb sucking reflex establishes neurological pathways crucial for future breast feeding and for speech development.

Thumb sucking habits are prevalent among children and, according to the American Dental Association (ADA), in most cases thumb sucking spontaneously ceases between the ages of two and four years of age. Peer pressure causes many school-aged children to stop placing their thumbs in their mouths.

Everyone has their ways of reducing anxiety and relieving stress. Some ways are considered healthy and socially acceptable. Others, not so much. For instance, thumbsucking is considered normal as an infant but is frowned upon as you get older. But if it doesn't hurt anyone and it makes you feel better, what's the big deal? Well, sucking on your thumb can actually create oral health problems for you. If you're an adult who sucks your thumb, we'll throw some tips your way to kick the habit and keep you smiling.

Sucking on thumbs, fingers, or pacifiers can calm babies and young children because it helps them feel secure and safe. Johns Hopkins Medicine points out that nearly nine out of 10 babies start to suck on their thumb or another part of their hands just hours after birth. They note that thumb-sucking shouldn't cause any problems if children stop by 5, and children usually stop on their own between the ages of 2 and 4. For some people, however, the behavior continues through adulthood.

Older children and adults seem to suck their thumbs to find comfort and security just like infants do. A journal of pediatrics, Minerva Pediatrica, performed a neurological study of people from 5 to 25 years old who were still in the habit of sucking their thumbs and found that thumb sucking stimulates certain receptors that release physical and psychological tension. But that release of tension can come at a cost to your oral health.

It is typical for babies to suck their thumbs at one point or another. Most children stop once they reach toddler age, however some children carry the habit on for many years. Sucking your thumb is a bad habit. Not only can it cause damage to your teeth, it can also cause you embarrassment. Here are a few tips on how to stop.[1]XResearch source

These threats to red pandas are compounded by climate change and natural disasters, inadequate enforcement of laws and regulations, and limited investment in red panda conservation by local governments. Red pandas have bred with some reliability in zoos throughout North America, Europe and Asia. As they decline in the wild, growing and maintaining self-sustaining populations in zoos is a high priority as a hedge against extinction and to learn more about species biology.

Fingerprint authentication has been used in one form or another since the 19th century. As a result, most people are already aware that fingerprints can be used as a unique identifier. That translates into less resistance to adopt fingerprint scanners as a means of verifying identity. On a purely psychological level, people are accustomed to using their hands to open doors, enter passcodes, or manipulate keys, so placing their thumb on a scanner comes more naturally to them than some other forms of biometric verification. This familiarity also comes from popular culture. Thanks to television and film, most people recognize this technology while the other modalities have just started to become more common.

In the short term, yes, but those changes are often temporary. People who perform manual labor that exposes their fingertips to abrasive or corrosive surfaces may be at risk of losing some fingerprint details over time. However, according to experts, once the heavy work has stopped completely, the ridges on the fingers will grow more prominent. Even in instances where the fingerprints are burned away with acid, they usually end up growing back. As with scarring, the burn marks can even become an identifying marker. In short, in cases other than natural diseases and old age, the change in fingerprint patterns is temporary.

Sucking a dummy, thumb or finger can cause changes to the teeth and jaws if it becomes a long-term habit. The younger the age at which a child stops, the more likely their teeth and jaws will not have any issues and correct the growth problems naturally.
