Do energy drinks cause your pupils to dilate?

Yes, energy drinks can cause pupil dilation, a condition known as mydriasis. This effect is primarily due to the caffeine and other stimulants found in these beverages, which can activate the sympathetic nervous system. Increased adrenaline levels from these stimulants may also contribute to the dilation of pupils. However, the degree of dilation can vary based on individual sensitivity and the specific ingredients in the energy drink.
