Do you know a sensation in which it seems like shivers run over your head? It can resemble an itch and be very annoying. For many it causes serious discomfort. The reasons for this may be in the emotional state, and the effects of parasites, and skin diseases , etc.
The feeling of "goose bumps" has long been known to many people. It is often determined by such phrases as "goosebumps" (skin that is covered with "goose bumps", resembles goose) or "hair on the head on end". Strong emotional states, such as sexual arousal, fear and others, can cause a similar condition. It can also be caused by a feeling of cold. In a scientific way such a symptom as "goose bumps" is called a pilomotor reflex. It is caused by the stimulation of sensory peripheral nerves, which leads to the excitation of nerve peripheral endings, which are responsible for the contraction of smooth muscles, which is associated with the hair follicles. And with the contraction of the muscles of the follicles, the hair begins to rise. Lifting the hair due to "goose bumps" is scientifically called piloection.
Shivers on the head - a phenomenon that occurs more often in animals than in humans. The piloerectomy that occurs in humans is only a rudimentary reflex, which now lacks any meaning. It causes "goose bumps". The causes of this phenomenon is that the hair of most mammals rises to protect the body from the influence of cold air masses. Also, in the case of animals, piloerection occurs in the event of a threat from another beast - the raised wool gives its owner a more massive and frightening appearance.
In humans, the creepy hair in the head or the hair lifted on end is a phenomenon that occurs not only because of cold or fright, but also as a result of a whole range of feelings - admiration, a sense of satisfaction or pleasure. It can also be caused by some sounds, for example, metal creaking about glass, etc. In this case, the creeps in the head disappear together with the cause that caused them. But what if this feeling lasts for a considerable time?
It does not always goosebumps on the head for innocuous reasons. The reasons can be in the neurological state of a person. Pilomotor reflex is something that most often occurs in people who are easily excitable, anxious, suspicious. Therefore, the doctor should pay attention to the nature of the patient who appeals to him with complaints of goose bumps. The reasons for this condition can be the patient's moral instability and nervousness.
And now more about this syndrome. As a rule, the goose bumps constantly shift. At first this sensation can arise in the area of the scapula, then on the forearm, then on the head. In the field of temples, there is often a sensation of tickling that intensifies before going to bed. Often there are shivers in your head, if you stroke your hand through your hair.
In itself, a similar sensation, reminiscent of the movement of small insects along the body, is not a disease. However, this may be a symptom of the disease. If this phenomenon occurs frequently and is combined with other symptoms - pain or numbness, in this case, contact the clinic. The examination of a patient with such a syndrome is the responsibility of a dermatologist and neurologist.
Goose bumps appear often in case you have been sitting for a long time. As a result, a nervous trunk was transmitted. If paresthesia in the patient only on the legs, then it can speak of a violation of blood circulation. And this can be a sign of diseases in which blood circulation in this area is disturbed. The spectrum of such diseases is wide - from varicose veins to arteriosclerosis of the legs. And in this case you need to contact the phlebologist.
Although the spiromotor reflex can be caused by harmless factors, it is still worth paying attention to such a phenomenon as goose bumps on the head. This may be relevant to any disease.
