The Danish Counsil for safe Swimming has listed the following points which should be observed:

• Never go swimming alone
• Do not swim within one hour after taking a meal
• Do not go swimming after strains, such as running, wait until you are relaxed.
• When swimming, follow the coast line
• Never go swimming in mires and marlpits
• Never stay for too long in the water - do not get cold
• Never shout for help in jest
• When swimming, stay close to lifesaver post or station
• Keep an eye on children, your own as well as others'
• Never go out deeper than where the water reaches your waistline
• Never go out where you cannot reach bottom
• Leave air mattresses on the shore
• Never swim after inflatable balls or animals, etc.
• Never dig holes into the dunes or slopes, and never crawl into holes, whether natural or manmade. Every year, accidents happen as a result of caving in

In certain weather conditions, stinging jellyfish wash up on the Danish coast. If you touch one, you will experience a stinging pain, because the jellyfish leaves small cysts of venom that burst after a while so that the venom comes into direct contact with the skin. Follow this advice:

• Never dry the site of the sting with a towel - you will simply break more of the cysts
• Instead, using long, light strokes, remove the cysts with an old-fashioned razor or something with a smooth, straight edge, e.g. a comb
• Then cover the affected area with a pain-relieving cream
