Can heatstroke cause eye pain?

Generally, in cases of mild heatstroke, eye pain typically does not occur; however, in cases of severe heatstroke, eye pain might develop. If discomfort occurs, it is recommended to closely monitor your physical condition and seek medical treatment at a formal hospital if necessary. Detailed analysis is as follows:

Mild heatstroke mainly involves temporary heat dissipation dysfunction of the body in a high-temperature environment. Symptoms primarily include dizziness, thirst, excessive sweating, and weakness in the limbs. At this stage, the body's abnormalities mainly manifest as general physical disturbances. The eyes are generally not significantly affected, and ocular blood circulation and nerve function remain largely normal. Therefore, eye pain typically does not occur. As long as the individual promptly moves out of the high-temperature environment, replenishes fluids, and rests, the body can recover relatively quickly without causing ocular discomfort.

In severe heatstroke, the body's core temperature rises sharply, affecting systemic blood circulation and nerve regulation. High temperatures may cause ocular blood vessel dilation, and the ocular tissues may become irritated due to congestion, leading to eye pain. Additionally, severe heatstroke may be accompanied by dehydration, causing significant loss of bodily fluids, which reduces tear secretion and results in a dry ocular surface, potentially causing dryness and eye pain. Moreover, damage to the nervous system caused by severe heatstroke may increase the sensitivity of ocular nerves, making pain more noticeable.

After experiencing heatstroke, avoid prolonged eye use and ensure sufficient eye rest. You may appropriately apply a clean, damp towel to the eyes to relieve discomfort. Furthermore, wearing sunglasses during outdoor activities in hot weather can reduce strong light stimulation to the eyes. Implementing proper heatstroke prevention measures can also help lower the risk of heatstroke.
