Eye twitching? Not a pleasant feeling. Unintentional movements of the eyelids, repeated every few seconds, are annoying and it is far from always possible to cope with them with a simple effort of will. According to doctors, a nervous tic itself is harmless to vision. But:
firstly, it causes discomfort; secondly, it testifies that not everything is all right with you. Why does the upper or lower eyelid twitch? It is extremely important to answer this question. After all, if you find the cause of the phenomenon, then it will be easier to understand how to deal with it.
How does it work?
Muscles contract, receiving nerve impulses, and they in turn are due to the electrical activity of the brain. Sometimes this electrical activity becomes chaotic for a second – something like a “flash” occurs, forcing the muscles of the eyelid to contract. Most of the time, this occurs when fatigue, high levels, arousal from excess caffeine, or overuse of the eyes themselves. If a tick appears, you should pay attention to the amount of coffee and tea you drink, take up the regimen, and improve your sleep.
What can cause a nervous tic?
Fatigue and stress cause overstrain of the nervous system, which is why accidental breakdowns from nerve impulses in the brain occur more often. Coffee also has a negative effect on the nerves: if your hands are shaking from drinking this drink, do not be surprised that your eyes may also twitch. Do not forget that too bright light, prolonged work at the computer or reading in low light can act as catalysts for a nervous tic. Among other relatively common, but generally not dangerous reasons, one can single out: alcohol intoxication, smoking, a temporary decrease in immunity (say, after a recent flu or acute respiratory disease) or malnutrition, as a result of which the body receives less magnesium and vitamin D (a deficiency of these elements leads to difficulties with muscle relaxation).
In general, if the body signals accumulated fatigue with the help of a twitching eye, you should not ignore these signals. If simple measures have not worked in a few days, and your stress or anxiety levels do not decrease, you may need to deal with them more seriously – with the help of medications or non-drug methods such as psychotherapy.
