Isle of Man Harbours and Coastguard is encouraging everyone to respect the water, understand the risks and never underestimate the power of the sea. Isle of Man Harbours, coastguards and the RNLI are people to take extra care on the island's coastline over the summer. They want people to think carefully before entering the water, using inflatables or taking risks around harbours. They have issued advice on cold water shock, the dangers of jumping into water, and what people should do if they find themselves in trouble. Cold water shock Cold water shock typically happens in water at about 15 degrees, which is the current temperature of the water surrounding the Island. It is the body's involuntary response to sudden immersion, which can bring on rapid breathing, panic and loss of muscle control. "Many people do not appreciate how quickly cold water can incapacitate even strong swimmers, particularly if they unexpectedly enter the sea," said Andy Mulhern, Harbours and Coastguard Operations Officer. He said that to mitigate this risk, people should acclimatise to the water gradually, rather than jumping straight in. People should also avoid excessive alcohol beforehand and check water temperatures at the spot they plan to swim. Think before you jump "We are especially concerned about people jumping into harbours, swimming in areas used by vessels and relying on cheap inflatables that are not suited to our sea conditions," Mulhern said. "A lifejacket can make the difference between life and death." "Offshore winds and tidal currents can carry inflatables away from the shore in a matter of minutes." "Water depth can also deceive," Mulhern added. A man in Douglas was seriously injured recently by jumping into what he thought was deeper water than it turned out to be. Mulhern said people should check for any hidden hazards under the water, such as steps, and rocks, check conditions, and wear appropriate safety equipment. If you get into trouble James Kellet, RNLI Water Safety Officer at Peel Lifeboat Station, said drowning could happen "much more quickly than people realise". People should tilt their heads back with their ears submerged, relax and try to breathe normally. Hands and legs should be moved to help stay afloat. "By doing this, you give yourself the chance to rest and recover your breathing," Kellet said. "Once you've regained control of your breathing, you can call for help or swim to safety. If you see someone in trouble, call 999 and ask for the Coastguard." The RNLI and Coastguard also advise checking tide times and weather before they go out. Anyone using an inflatable should always wear a buoyancy aid and watch for offshore winds. If caught in a rip current, people should swim parallel to the shore, rather than attempting to swim against the current.
