Before taking a dip in the ocean: essential factors to consider for sea water safety

In the warmer months, lakes offer a refreshing escape from the heat. However, it's essential to be aware of potential health hazards that may be present in these bodies of water. Here's a guide to help you identify and avoid these risks.

Firstly, let's talk about blue-green algae, also known as Harmful Algal Blooms (HABs). These can give the water a green, blue, or white appearance, either as streaks, a blanket on the surface, or "clouds" in the water. Swimmers should avoid areas with visible algal blooms as ingestion or contact can cause a range of health issues, including gastrointestinal symptoms, skin irritation, and respiratory problems. To stay informed, check local health advisories or boating reports for information on algal blooms in the area you plan to visit.

Another potential hazard is Cercariae, larval stages of certain parasitic flatworms often found in water. These microscopic organisms can cause swimmer’s itch, a condition characterized by skin irritation and itching. After swimming, it's recommended to shower immediately to remove any attached Cercariae.

Vibrio bacteria, common in brackish or saltwater environments, can also pose a risk. Infections can cause gastrointestinal illness or wound infections if you have open wounds. To minimize risk, avoid swimming with open wounds and rinse thoroughly after swimming.

General precautions include never drinking lake water, avoiding swimming in areas with visible signs of algae or after heavy rainstorms, and showering after swimming to remove bacteria or parasites. It's also crucial to check local health and environmental reports for updates on water quality.

When swimming in natural bodies of water, be aware of underwater hazards like rocks and plants. Use protective gear if swimming in potentially contaminated waters.

Remember, the most common health hazard in lakes is blue-green algae, which can make the water green or blue-green. Bacteria or pathogens can cause reactions after swimming, but they are often invisible to the naked eye. If you cannot see your feet while standing knee-deep in water containing blue-green algae, you should not swim.

In the Baltic Sea, Vibrions are a concern, particularly in warmer temperatures. Existing wounds can heal worse due to vibriosis, a condition caused by Vibrions.

Cercariae require water temperatures around 20 degrees Celsius to thrive, and local authorities may warn if a body of water is contaminated with them. After swimming, it's recommended to rub off vigorously with a towel and put on fresh clothes.

To stay informed, contact local health departments or environmental agencies for information on water quality. Learn about common waterborne pathogens and their symptoms to recognize potential health risks. Keep contact information for local emergency services handy in case of an incident.
