While volcanoes are a beautiful part of Hawaii’s natural landscape and attract thousands of tourists to the islands each year, they also emit toxic gases. Locals call this fog-like form of air pollution “vog.” You should take measures to protect yourself from its harmful effects, according to Drs. Donald Nikaitani and Richard Pekala of Kona-Kohala Health Care Services, a health clinic in Kailua-Kona. Below, they break down everything you need to know about vog.

What Is Vog?

Vog, a portmanteau of “volcanic fog,” is a form of air pollution that appears as a haze over the islands. It mostly consists of carbon dioxide, sulfur dioxide, and water vapor. While the latter isn’t harmful to breathe in, carbon dioxide exposure can damage the body’s organs and contribute to respiratory failure in large amounts. Sulfur dioxide not only smells unpleasant, but it is also toxic, irritating skin, nose, eyes, and lungs.

What Are the Symptoms of Exposure?

Signs of excessive vog exposure include coughing, headaches, lethargy, breathing issues, and even feeling like you have the flu. If you have bronchitis, emphysema, asthma, or a similar lung issue, breathing in this hazy air will worsen your condition. Dense vog can also cause vehicular accidents when it shrouds the road.

How Can You Prevent Issues & Treat Existing Ones?

Since vog is drying, hydrate your body. Drink lots of water and rinse out your nose and eyes with products from your local drug store. Stay inside on days when the pollution is excessive, and head to a health clinic right away if you’re having trouble breathing, feel extremely tired, or exhibiting flu-like symptoms. Use an air purifier and wear a mask outside when the contamination levels are high.
