If you have allergies or asthma, beware the "red tide" on Florida beaches. Just one hour on the beach during an algae bloom can cause a ten percent decrease in lung function and trigger asthma symptoms.

As if decreased lung function wasn't bad enough -- it can take as long as five days for an asthmatic or susceptible person's lungs to return to normal. Just one hour of exposure to a red tide has a lasting impact on your body. Even people without asthma may experience watery eyes, a runny nose, and cough. Researchers aren't sure what it is about the red tide that is an irritant or allergen.

What causes a red tide? Algae called karenia brevis multiply in the Gulf of Mexico and cause the red tides along Florida's gulf coast. Sometimes, you can see the color change -- the water takes on a brownish color. More often, you'll notice the smell. A red tide causes fish to die off in large numbers; a terrible fish odor comes with a red tide, whether you see the color or not.

Other coastal areas do experience red tides from time to time. However, different types of algae can be at work. Different organisms may not have such a strong effect on the lungs. However, researchers are concerned that the red tides may be a growing threat to coastal areas and the people who live there.

Pay attention to your environment if you have asthma or are susceptible to asthma symptoms! If you live in or plan to visit an area of Florida that experiences red tides, you can check the National Oceanic and Atmospheric Administration website for information. NOAA keeps track of algae blooms; if you know a red tide is on the way, you can avoid the beaches and protect your lungs. There are plenty of things to do in Florida that don't involve beach time!
