Sometimes a sunburn is so bad, your entire body reacts. It's a phenomenon usually called sun poisoning, though it doesn't actually mean you've been poisoned. Sun poisoning is an extreme sunburn that can be accompanied by symptoms like nausea, vomiting, chills, fever, headache, and a general feeling of being sick.
