Most people realize that the symptom of many diseases is dilated pupils. The reasons for this manifestation may lie in a completely different. For example, it has been scientifically proven that dilated pupils are a sign of an excited state or a good mood of a person. In addition, this signal may be a standard response to light.
You can confirm these facts at home, it is enough to trace the condition of the eyes at the moment of joy and sadness. If during the day a person was in a stressful situation or was just gloomy, then the pupils will be narrowed. Experienced Don Juans noticed that when communicating with a woman who has a genuine interest in a man, her pupils are dilated and seem to give a signal of willingness to accept any signs of attention. This is a state of mild excitement and a sign of good mood.
Why are dilated pupils a standard response to light? The fact is that our body is designed in such a way as to protect the retina of the eye from damage and ultraviolet rays. That is why in bright sunshine or excessive lighting of the room, you can observe a narrowing of the pupil or the so-called "closing of the eye." And vice versa, when dilated pupils appear in the twilight room, the reasons for this process relate to the direct function of the eye - to distinguish colors and provide clear vision. In the dark, it becomes more difficult for a person to see many things, the muscles of the eye focus, tighten and the eyeball grows in size.
An increase in pupil size occurs when a large amount of adrenaline is released into the blood. This explains why a person has a dilated pupil when he is very afraid of something or during extreme rest.
The condition of the eyes can help an ordinary person to characterize people who meet on his life path. It was found that narrow pupils indicate nervousness, an unstable psycho-emotional atmosphere, and dilated ones speak of strong nerves and a calm disposition. Thus, the state of the nervous system affects not only mood and health, but also the condition of the eyes.
Dilated pupils: causes of disease.
It's no secret that such a reaction in humans can occur with the use of narcotic drugs, alcoholic beverages, and even psychotropic drugs. Excessive and regular consumption of alcohol leads to the corresponding disease, which is problematic to get rid of. And the use of drugs once will lead to a repeat of admission, and then to systematic use.
If we talk about the causes of dilated pupils, then this symptom is caused by pathology of the thyroid gland or head injury. And if there are additional signs in the form of a general deterioration in well-being: headaches, increased blood pressure, nausea and vomiting, you should immediately consult a doctor who can make an accurate diagnosis and provide timely help.
In addition, the result of many diseases can be dilated pupils. The reasons for their manifestation lie in the drugs that are prescribed during treatment. For example, "Atropine" is a tool used to get rid of many ailments. Often prescribed to people suffering from a violation of the gastrointestinal tract. Even excessive sweating can be stopped with the help of this drug, since it reduces the secretion of glands, in particular sweat glands.
Thus, the condition of the eyes may be a symptom of any problems in the human body or serious diseases. But still, in most cases, the expansion or contraction of the pupil is a moment that reflects the characteristic features of people, or a traditional reaction to external factors of influence.
