To have a safe trip, you should equip yourself with the necessary knowledge to protect yourself from unexpected dangers.

1. Warm up before going into the sea.

The environment on land and the environment underwater are different, so you need time to adapt. Before going into the sea, you should warm up your limbs, do some exercises or jog a short distance to avoid cramps before immersing yourself in the water. However, you should not overexert yourself and you should enter the water slowly, don't rush in.

2. Avoid prolonged sun exposure.

Intense sunlight is not good for your health. Therefore, you shouldn't sunbathe for too long before going into the water as it can easily lead to a sudden cold.

3. Avoid going into the water on an empty or full stomach.

When going to the beach, you shouldn't go into the water too hungry or too full. It's best to have a light snack and bring along some pastries, fruit, or canned goods because you'll expend a lot of energy after swimming.

4. Do not swim too far from the shore.

When swimming too far from shore, you will face large waves and unforeseen risks. Therefore, you must occasionally pay attention to what is behind you. The first time you go into the water should not exceed 15 minutes. Do not swim more than 15 meters from the shore or in areas deeper than 5 meters.

5. Avoid swimming in the sea on days with big waves.

Avoid swimming or going to beaches with rip currents, as these are very dangerous for swimmers. You should check the weather forecast and research beach information beforehand. In particular, avoid swimming on days with large waves, storms, or when the temperature is below 18 degrees Celsius. If you see an unusually calm beach, the water receding, and flocks of birds flying around, immediately get out of the water and find higher ground or a hillside.

6. Do not swim outside the safe zone.

Each beach usually has signs warning of deep, dangerous water areas. You should strictly adhere to the beach's regulations and not venture too far from the safe zone, otherwise you may not be able to swim back to shore, encounter dangerous fish, or be swept away by strong waves.

7. Avoid piers and pillars.

Coastal cities often have scattered piers or mooring posts. When swimming, you should avoid these areas as they are hiding places for mollusks such as jellyfish that can attack. In case of a jellyfish sting, get out of the water, rub with lemon juice, and then rinse with fresh water.

8. Avoid rip currents.

Beaches near reclaimed land areas often have holes, depressions, and unexpected rip currents. To escape these currents, don't panic. Always remember that rip currents don't pull you to the bottom; they only carry things away from the shore. Don't try to swim against the current; try to swim perpendicular to it. For those who can't swim or are exhausted, let yourself float with the current and wait for rescue.

9. In case immediate disembarkation is required.

If you experience itching, feeling cold, unusual fatigue, headache or pain in the back of the neck, cramps, visual disturbances, bloating, or pain in your elbows and knees, you must immediately seek to get ashore.

10. Always go with one or two other people.

To ensure safety, you should be careful when swimming and avoid going too far from the shore. Always go with one or two other people; the more people, the safer it is and the more people can help each other in case of an emergency.

11. Save yourself

Stay calm, close your eyes, keep your mouth shut, and hold your breath so that your lungs don't fill with water, instead acting as a life raft to gradually lift you to the surface. Use your hands or feet as paddles, propelling your head above the water. This way, you can survive underwater for quite a while until rescue arrives or use the current to swim to shallower water.

12. Certain situations prohibit swimming in the sea.

People with conditions such as bronchitis, asthma, tuberculosis, cardiovascular disease, nephritis, chronic otitis media with perforated eardrum, easily irritated nerves, and those who are frequently sensitive to cold should avoid swimming in the sea.
