Safe Sea jellyfish sting protective lotions gives 82% protection
Using Safe Sea means the risk for jellie stings is reduced with over 80% due to a double blind study. The test candidates had Safe Sea on one half of the body and a placebo at the other. It was a double blind study meaning neither the cadidates nor the researchers knew where Safe sea was put on. At 82 swims 11 stings occured on the body half with placebo. Only 2 stings occured at the body half with Safe sea. This nmeans a risk reduction with 82%.
Methods A double-blind, randomized, placebo-controlled trial occurred at the Dry Tortugas National Park, FL, USA and Sapodilla Cayes, Belize. Participants were healthy volunteers planning to snorkel for 30 to 45 minutes. Ten minutes prior to swimming, each participant was directly observed applying a blinded sample of Safe Sea (Nidaria Technology Ltd, Jordan Valley, Israel) to one side of their body and a blinded sample of Coppertone® (Schering-Plough, Kenilworth, NJ, USA) to the contralateral side as placebo control. Masked 26 g samples of both Safe Sea SPF15 and Coppertone® SPF15 were provided in identical containers to achieve 2 mg/cm2 coverage. Sides were randomly chosen by participants. The incidence of jellyfish stings was the main outcome measure. This was assessed by participant interview and examination as subjects exited the water.
Results A total of 82 observed water exposures occurred. Thirteen jellyfish stings occurred during the study period for a 16% incidence. Eleven jellyfish stings occurred with placebo, two with the sting inhibitor, resulting in a relative risk reduction of 82% (95% confidence interval: 21%–96%; p = 0.02). No seabather’s eruption or side effects occurred.
Conclusions Safe Sea is a topical barrier cream effective at preventing >80% jellyfish stings under real-world conditions.
