Parents take a number of precautions to stop children from developing sunburn during the summer, but many don't know that common food and drinks, such as lime juice, lemonade, grapefruit or even celery may put children at risk for a nasty sunburn.

Curious about how citrus fruits can make skin more vulnerable to the sun? Learn more with this overview about the skin condition citrus fruits cause. Take steps to prevent your little one from developing this painful problem.


The Link Between Citrus Fruits and Sunburn

Many people enjoy downing summer drinks such as fresh limeade or lemonade or eating citrus fruits or celery to cool off when the weather gets warm. Afterward, however, some parents and children regret their choice of drink or snack. That's because certain photosensitizing plant compounds, much like certain medications, make the skin extra sensitive to sunlight. The result can leave you feeling burned and bummed. But there is an easy solution: Wash your hands and your entire face after consuming citrus fruits or celery.

What Is Phytophotodermatitis?

Citrus fruits and celery can cause a sun-induced skin sensitivity condition known as "phytophotodermatitis." The condition occurs when dripping juice from fruits such as limes, lemons, oranges, grapefruit, celery or even parsnip or fennel come into contact with the skin. Other plants may produce the same effect in certain individuals, so check with a medical professional if you fear you're at risk.

Phytophotodermatitis can cause strong reactions, resulting in sunburn, rash, hives and blistering. Others may be unaffected by the condition, even if juice from the offending fruits touches their skin. Those vulnerable to sunburn, however, should take precautions.

Parents and childcare providers should make sure kids wash their hands and faces carefully (or even arms and legs if they are particularly messy eaters) before heading outdoors.

Why risk exposing a child to sunburn, blisters or hives if these conditions can easily be prevented? Explain the risk to children if they resist washing up after consuming citrus fruits and other plants that cause phytophotodermatitis. If the child won't cooperate, keep him inside or deny him citrus fruits when it's hot outside. 

Prevention Stops Phytophotodermatitis

Prevention stands out as the best way to stop a child or adult from developing phytophotodermatitis. But if you or your children manage to develop the condition anyway, use hydrocortisone cream to reduce inflammation and a cool washcloth to soothe the burn. Severe cases may require oral antihistamines or even a steroid shot or pill. Consider bringing along those wet wipes or damp washcloths placed in a plastic bag for an easy way to wash off.
