The mass fish deaths of unknown cause in the Central region of our country are an alarming bell about marine pollution – a story that has long been thought to be a joke but is true. The sea is not only polluted by untreated wastewater from ships, from industrial parks, and from daily activities, but also because the awareness of preserving the marine environment of each Vietnamese person is not high.
Perhaps the mass fish deaths have made people “wake up”, but for a long time, Vietnam’s sea has also shown signs of pollution in many places.
If you swim or eat seafood in places where the sea is contaminated, the risk of poisoning, even death, will be very high.
How to protect yourself from the danger of toxic sea: Avoid swimming and eating seafood in potentially toxic waters.
Poisonous jellyfish bite
Jellyfish is an animal that specializes in causing itching, but what is more dangerous is that the toxins from this species can cause allergies, redness, and even severe allergies. There are some Vietnamese sea areas that have a lot of jellyfish and just touching the jellyfish will make you feel a burning sensation.
How to protect yourself from jellyfish allergies: If while swimming you feel a burning pain on your skin, like a burning sensation, immediately swim to shore, then use a cotton towel to dry the skin, move to a place with fresh water and wash your body. If your condition gets worse, go to the nearest medical center for examination and treatment.
Countercurrent – Offshore current
Rip currents or rip currents are one of the biggest dangers you can encounter when traveling to the beach. If the current appears, it can pull you away from shore and make you panic and exhausted when trying to swim against the current. This is one of the main reasons why many people drown while swimming not only in Vietnam but also in many places around the world. It sounds far-fetched, but if you’re not careful, you could completely lose your life!
Signs of backflow are not easy to detect, but you can still rely on the following characteristics:
– The color is darker because the water is deeper.
– The water surface is calmer, often with smaller waves.
– Sometimes you can see debris or water bubbles floating on the surface of the current and drifting out to sea.
– The water surface is calm and looks very safe.
So how to stay safe when the danger is backflow?
– Do not swim away from places with safety signs.
– When caught in a reverse current, stay calm, observe, raise your hands high to ask for help, and do not try to swim back to shore. If you are confident in your swimming ability, swim parallel to the shore, absolutely do not swim against it, the current will go towards where the waves hit the shore so you only need to swim a little bit to reach the shore. Okay!
– Not subjective: On days with big waves, fewer people drown than on days with big waves due to being subjective.
Sunburn – Sunburn
It may sound funny but the truth is that sunburn or sunburn is not funny at all. Did you know that sunburn or sunburn is a result of UV rays damaging your skin, while on beaches where there is no shade, the white color of the sand has the ability to reflect sunlight? The sun is higher than usual. In the world today, skin cancer is one of the leading causes of death, and it is those UV rays that are the culprits that you cannot see.
How to protect yourself from sunburn: What you need to do is use sunscreen whether you go out or go to the beach. It’s best to choose a waterproof sunscreen so that even when you go into the ocean, your skin is still protected. You should reapply every 60 – 80 minutes when you go into the ocean.
In addition, don’t be foolish to go to the beach when the sunlight is too strong, around noon and early afternoon, let the sun cool down a bit and then go to the beach.
Seafood allergy
Although seafood is rich in nutritional value, not everyone can eat seafood. If you have a seafood allergy, not only will you miss out on a fun trip, but you will also be extremely tired. Symptoms of seafood allergy are that the body starts with sweating, fatigue, mild stomach pain and gradually turns to serious reactions such as severe stomach pain, nausea, headache, and tongue numbness. Some people may also experience symptoms of chest pain and difficulty breathing.
How to protect yourself against the risk of seafood allergy: If you have a history of seafood allergies, it’s best not to eat it. Also, don’t try strange seafood if your digestive system is not good.
Heat shock
Heat stroke doesn’t sound too dangerous, but the truth is that it can be deadly if not careful. If the temperature and humidity are too much for your body to endure, you will experience fatigue, dizziness, and can cause death if heatstroke occurs.
How to protect yourself from the risk of heat stroke: If it’s hot, wear cool clothes and don’t walk in the hot sun. Also drink plenty of water to avoid dehydration, and don’t participate in many fun activities on the beach. If you feel dizzy or have cramps, give your body rest to avoid exhaustion or heat stroke.
