Water sports or just swimming in the waters of the oceans and seas, in addition to pleasure, can bring unpleasant situations. I hope this never happens, but it's better to be prepared for anything. so, let's look at some situations regarding any kind of entertainment on the water, whether it's diving, surfing or just swimming.
the most common case is waves. when you are covered and twisted so that you lose your orientation in space, you do not have to resist the wave, it is stronger than you. this will last 10-20 seconds.
While under water, group up, hugging your head with your hands, thus protecting yourself from hitting your head on the rocks, just relax, hold your breath. after the spinning has stopped, calmly float up, turn around to face the next oncoming wave, take air into your lungs and dive under the wave.



Тhe next common case is  muscle spasms.
they occur due to excessive physical exertion, hypothermia, tight shoes.
Most often, cramps cover the calf muscles. In this situation, you need to take a deep breath, dive vertically into the water with your head, straighten your legs, grab your big toes with your hands and pull hard on yourself.
Don't worry and stay calm, if your leg is cramped, it means you still have three limbs to get to shore.

The next point is the flow of water.

Do not fight the current, do not try to swim against it. Stay calm, keep your strength, breathe, don't panic.
Give in to the flow, after a while the current will weaken, and you can row towards the waves that will help you get ashore.
Try to attract the attention of other people on the shore by waving your arms.

Seaanimals.
you should be aware of what kind of marine inhabitants live there. For example, Australians know that deadly jellyfish live off the northern shores of their continent, Californians always have a chance to encounter a great white shark, and on the shores of the Atlantic Ocean you can suffer from sea urchin needles.
In addition to sharks, jellyfish and sea urchins, stingrays, sea snakes and other inhabitants of the oceans and seas pose a danger to the surfer.
If you notice any of the above, you need to warn everyone around and swim quickly to the shore, on the shore, tell the rescuers about the danger if they are present on the beach. If a sea creature has harmed you, you should immediately seek medical help.
To avoid collisions with sharks, it is worth staying away from spots where they often visit, do not swim in muddy waters, do not ride at dawn and at sunset and in river mouths during rain, and also never ride with an open wound — sharks can smell blood for several kilometers. To protect yourself from attack as much as possible, you can purchase a portable shark repeller.
As for the Philippines, everything is very good here. There are practically no dangerous creatures. There are only harmless fish and huge turtles. It is very rare to come across jellyfish or a sea snake (but the chance is minimal). If we talk about sharks, then only a few spots have seen small reef sharks, and they are safe for humans if they are not provoked. The water in the Indian Ocean off the coast of the Philippines is too warm for killer sharks to swim here.
Sea urchins are perhaps the most dangerous creatures for swimmers in the Philippines. just put on special shoes and look at your feet before you step on the bottom.
Let's summarize. Don't panic. keep calm in any situation. Кeeping in mind the fact that the ocean is an unpredictable element, without playing by the rules of which, you can easily get injured or lose your life. I sincerely hope that all the above dangers will pass you by, and that you will remember how to behave in the ocean.
