4. Dehydration
Sun poisoning affects more than just the skin; it can affect the vital systems within the body. When you are exposed to the sun for a long period of time, your body produces excessive heat, which decreases the volume of fluids within your body. When that happens, dehydration can result. Symptoms of dehydration include extreme thirst, dizziness, and lethargy. Your skin can also become very dry, and your urine output can decrease. Any urine that you do produce may be dark yellow in color.
Dehydration can be a life-threatening condition if it is not treated properly, which is another reason why sun poisoning is so dangerous. If left untreated, dehydration can result in reduce your blood volume levels, which can sent your body into a state of shock. If you are experiencing any of the signs of dehydration, along with any of the other symptoms on this list, seek prompt medical care, as it is likely that you are suffering from sun poisoning.
