what causes sun poisoning

Sun poisoning is usually caused by severe overexposure to ultraviolet (UV) light , which leads to an intense sunburn rather than actual poisoning.

Common causes

• Staying in direct sun too long, especially between 10 a.m. and 4 p.m. when rays are strongest.

• Not using sunscreen, or using too little / low-SPF sunscreen.

• Fair skin, which burns more easily.

• Sun-sensitive medications, such as some antibiotics, diuretics, acne drugs, and other medicines that increase UV sensitivity.

• Sun exposure reflected off water, sand, or snow, which can increase UV exposure.

• Higher altitude or living closer to the equator, where UV radiation is stronger.

What it really means

“Sun poisoning” is a lay term, not a formal diagnosis, and it usually refers to a bad sunburn with more widespread symptoms like headache, nausea, feverish feeling, dizziness, or dehydration.

When to worry

If the sunburn comes with blistering over a large area, confusion, fainting, vomiting, or severe dehydration, it needs prompt medical attention.

Prevention

• Use broad-spectrum SPF 30+ sunscreen and reapply regularly.
• Wear protective clothing, a hat, and sunglasses.
• Seek shade during peak UV hours.
• Be extra careful if you take sun-sensitizing medications.
