More Info

---

Experiencing eye discomfort after an episode of heat exhaustion can be concerning, and it’s important to understand the potential causes and solutions. Based on your description, it seems that you are dealing with a combination of factors that could be contributing to your symptoms, including heat exhaustion, fatigue from lack of sleep, and possibly dehydration.


Causes of Eye Discomfort After Heat Exhaustion
1. Heat Exhaustion: When the body overheats, it can lead to various symptoms, including headaches, dizziness, and fatigue. The eyes can also be affected, as heat can cause blood vessels in the eyes to dilate, leading to a sensation of discomfort or changes in vision, such as seeing colors differently (e.g., white light appearing yellow).

2. Dehydration: Heat exhaustion often leads to dehydration, which can cause dry eyes. When the eyes do not have enough moisture, they can become irritated and uncomfortable. Dehydration can also lead to headaches, which may further exacerbate the feeling of discomfort in your eyes.

3. Fatigue: You mentioned that you have been staying up late, which can lead to eye strain. Prolonged periods of reading or looking at screens without adequate breaks can cause symptoms like dryness, irritation, and blurred vision. This is often referred to as digital eye strain or computer vision syndrome.

4. Fever: A mild fever, such as the 38°C you mentioned, can also contribute to feelings of discomfort. Fever can lead to systemic symptoms, including headaches and fatigue, which can indirectly affect your eyes.


Solutions and Recommendations
1. Hydration: Ensure you are drinking plenty of fluids, especially water, to help combat dehydration. Electrolyte solutions can also be beneficial if you have lost fluids through sweating.

2. Rest: Allow your body to recover from heat exhaustion by getting adequate rest. Sleep is crucial for overall recovery, and it can help alleviate symptoms of fatigue and eye strain.

3. Eye Care: If your eyes feel dry or irritated, consider using artificial tears or lubricating eye drops to help soothe discomfort. Avoid rubbing your eyes, as this can worsen irritation.

4. Limit Screen Time: If you are experiencing eye strain, try to reduce the amount of time spent on screens. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This can help reduce eye fatigue.

5. Seek Medical Attention: If your symptoms persist or worsen, it is important to consult with a healthcare professional. They can evaluate your condition more thoroughly and rule out any underlying issues, such as infections or more serious eye conditions.

6. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as persistent headaches, changes in vision, or increased sensitivity to light. This information can be helpful for your healthcare provider in diagnosing your condition.

In summary, your eye discomfort following heat exhaustion is likely a combination of dehydration, fatigue, and possibly the effects of fever. By focusing on hydration, rest, and proper eye care, you can help alleviate your symptoms. However, do not hesitate to seek medical advice if your condition does not improve or if you have any concerns about your health.
