To treat sun poisoning, you can take the following steps at home:

• Get out of the sun immediately to prevent further UV exposure.
• Take a cool (not cold) shower or bath, or apply cool compresses to soothe the skin.
• Apply aloe vera gel or a thick, fragrance-free moisturizer to keep the skin hydrated.
• Drink plenty of water to stay hydrated.
• Take over-the-counter anti-inflammatory medications like ibuprofen or acetaminophen to reduce pain and inflammation.
• Cover sunburned areas with clothing when going outside to protect from further damage

Seek medical attention if you experience severe symptoms such as:

• Blisters over a large area
• Facial swelling
• Headache, dizziness, confusion, or faintness
• Fever, chills, nausea, or vomiting
• Signs of dehydration or infection (increased redness, warmth, pus)

Medical treatment may include IV fluids, prescription steroids, antibiotics, or pain medications depending on severity

. To prevent sun poisoning, use broad-spectrum sunscreen with at least SPF 30, wear protective clothing, avoid peak sun hours (10 a.m. to 2 p.m.), and stay hydrated
