What is NOT recommended when washing an area stung by a jellyfish?

When dealing with jellyfish stings, it is important to understand the proper first aid measures to administer in order to prevent exacerbating the injury. Fresh water is not recommended for washing an area stung by a jellyfish because it can cause the stingers (nematocysts) that may still be on the skin to fire, injecting more venom into the person affected.

Using salt water or vinegar is considered safe, as they help to neutralize the stinging elements without triggering additional venom release. Warm water can help alleviate pain, but again, freshwater can lead to complications. Therefore, avoiding fresh water is crucial in managing jellyfish sting cases safely and effectively.
