Early Warning Signs of Sun Poisoning Explained Sun poisoning often starts with what seems like a regular sunburn, but the symptoms can become much more severe. In addition to redness and pain, you may experience blistering, swelling, fever, chills, headaches, nausea, dizziness, or dehydration. Recognizing these warning signs early can help you get the right care before the condition worsens. If you suspect sun poisoning, move to a cool, shaded area, drink plenty of water, avoid further sun exposure, and monitor your symptoms closely. Severe reactions or signs of dehydration should be evaluated by a healthcare professional. For more information about symptoms, treatment, recovery, and prevention, visit Sun Poisoning.
