Like allergies or the flu, red tide ebbs and flows with the season. And when it’s present along the coast and blown onshore, it can cause a variety of cold or flu-like symptoms in many – especially those with any kind of breathing condition. This includes people with severe or chronic respiratory conditions such as COPD, emphysema or asthma.

“Red tide is a particulate allergen containing brevetoxins that can cause mild burning in your nose and throat, watery eyes, and trigger histamine release and bronchospasms causing wheezing and shortness of breath in COPD and asthma patients,” said Raymond James, D.O. at the Boca Grande Health Clinic.

The good news is that these symptoms are usually temporary and go away shortly or within hours after you leave the red tide area.

Red tide symptoms are similar to those from allergies, the flu, or even COVID-19, which creates questions and concerns.

Tips for managing your health during red tide:

1.Check the marine forecast before you head out

2. Wear a particle filter mask

3. Over-the-counter antihistamines may decrease your symptoms

4. Seek medical help if your symptoms worsen

5. Temporarily move your activities further inland
