After being stung by jellyfish, you should first leave the jellyfish area quickly, remove the tentacles left on the skin and inhibit the release of toxins. Rinse with vinegar or seawater, remove tentacles with tweezers or sticks, or wear protective gloves to remove tentacles. Don't touch the tentacles or sting people directly. Then soak or rinse the stung part with seawater or vinegar 15-30 minutes.

This can inhibit the release of toxins from the activated stinger sac. It is particularly important to emphasize that before removing jellyfish stings and tentacles, do not rinse with fresh water, or apply hot compress, cold compress or massage. These measures may accelerate the release of toxins.
