Sanya hotel rafting

1. Pay attention to the weather. It is not suitable for snorkeling on cloudy, rainy or windy days, because the waves mainly come from the wind, and usually the wind is strong and the temperature is low on rainy days. When the wind and waves are strong, snorkeling is not only uncomfortable, but also affects physical fitness. In addition, low temperature can also cause physical discomfort.

2. Before snorkeling, please know the sea conditions and currents of the resort. Usually ask about the time of high tide and low tide, the area suitable for snorkeling, and the current situation nearby.

If the hotel offers snorkeling courses, please be sure to attend. Swimming is different from snorkeling (swimming is to spray your nose in the water and inhale from the water outlet; Snorkeling is the whole process of inhaling and exhaling through the mouth with a breathing tube. Never use your excellent swimming skills to treat snorkeling lightly.

Unless you have learned snorkeling skills, you should always wear a life jacket to ensure safety.

5. Pay attention to the direction of the water flow, and it is best to go upstream when entering the water, so that it will become downstream when you come back, which can save physical strength; Because when you come back, you are usually in poor physical strength. When you encounter countercurrent, you will accelerate your fatigue and increase your danger.

6. Please think ahead, what should you do in case of emergency (such as drowning and drifting)? And measure whether you have the ability to rescue?

7. Choose a snorkeling location. Considering that there are other people nearby or people often pass by. It is easier to get help in an emergency.

8. Whether you can swim or not, please prepare buoyancy AIDS for yourself, such as life jackets, life rafts or winter clothes.

9. The three treasures of snorkeling (face mirror, breathing tube and frog shoes) are indispensable. Most people may ignore the importance of frog shoes. In fact, frog shoes can provide powerful thrust, easily generate buoyancy and save physical strength.

10. Snorkeling must be accompanied by someone, and you can take care of each other when you have something.

1 1. Please check the tightness of the face mirror (not too loose or too tight) and whether the face mirror is easy to get water (there can be nothing between the face mirror and the face, even the hair will cause the mask to get water; Applying sunscreen on the face will also lead to the poor adsorption and water absorption of the face mirror), whether the breathing tube is easy to get water, whether the frog shoes are comfortable, and adjust all the equipment to the best state.

12. Pay attention to whether there are "fish tides", "sea urchin tides" and "jellyfish tides". I've seen it several times. The "fish tide" is a large number of hairtail, squid and dolphins. "Sea urchin tide" and "jellyfish tide" are a large number of sea urchins and jellyfish. When these things happen, they are very painful and easily stabbed by sea urchins and jellyfish. Please see a doctor as soon as possible. I was dried twice by sea urchin, and my back was red and swollen for several days, which made me feel terrible.

Snorkeling time

1. Look up and pay attention to the surrounding situation at any time, including the distance from the shore, the weather, whether there are ships, surface vehicles and snorkelers nearby.

2. When you unconsciously enter the flow area, whether it is downstream or upstream, please leave as soon as possible, so as not to consume physical strength due to upstream or be taken away from the shore due to downstream. In order to save energy, it is advisable to drift obliquely downstream.

3. Simple mirror drainage: water enters the mirror when snorkeling. Press the upper edge of the mirror with both hands and fingers, and then the water will be discharged from the lower part of the mirror. Please practice in the shallows first.

4. Simple breathing tube drainage: When the breathing tube is full of water, please blow hard and quickly to discharge the water. In addition, some well-designed breathing tubes have drain valves and check valves, which can effectively reduce the amount of seawater entering the breathing tubes.

5. Snorkeling time is suggested to be limited to less than one hour to avoid physical fatigue. Try to wear a waterproof watch to record the time.

6. In case of exhaustion, drifting or drowning, please be sure to tell yourself to be calm. Only when you are calm can you save yourself and ask for help. Sea water is buoyant, so if your legs can move continuously by pedaling a bicycle vertically, you shouldn't sink for no reason.

7. When your partner encounters an emergency, please ask for help immediately and evaluate whether you have the ability to rescue. When you go to the rescue, try to take floating tools with you. If both of them are already in the deep water area, please be sure to evaluate your rescue ability first, and don't rush to rescue. If you can't help yourself, please ask others for help first and pass the buoyancy-providing equipment to the drowning person.

Hidden dangers of snorkeling and its countermeasures;

1. Undercurrent and coral

Submarine undercurrent is the most deadly, and related accidents occur every year. There have been many accidents in Yalong Bay near Yalong Bay in Sanya, but it has been banned from going to sea since it was requisitioned. If you go to Dadonghai or Yalong Bay, there are hotels to provide relevant advice. You can think of undercurrent as a powerful current, which will drag you to the bottom of the sea or keep you away from the coastline! So when snorkeling, you must know the local environment and look at the hotel signs! If it says it's dangerous, you can't swim, don't run in, because it looks safe! If you don't write ... then please look at the island map and see which places around you are suitable for snorkeling. Choose those places! -or, at least choose a place with a little more people! Students who go to Maldives pay special attention. When you check in, you will be given a map of the island, which indicates which places are not suitable and which places are suitable. In addition, students who go to play in the rainy season should pay more attention to the fact that the water flow will be longer in the rainy season! ! Be sure to read the warning signs on the beach and don't rush into the sea blindly!

Besides undercurrent, the current itself is also very dangerous. If you read the snorkeling travel notes above 10, you will definitely find that some students mentioned "... I swam away from .......... and unconsciously felt that I couldn't swim back ... and then I tried my best ..." This story is not because of poor physical strength! ! ! It's because the current is too strong (mostly at the snorkeling point), he/she is busy watching the fish while snorkeling, and then he/she swims away ... and then he/she can only fight the current! Solution: Raise your head more+enhance driving force with fins+life jacket.

Coral is the thing that hurts you the most. This is common sense. Generally speaking, you will be injured in two situations. First, if you try to touch the rock, whether you want to climb up from the sea or unintentionally, if you touch it, your hand is likely to be scratched, because there is a sharp shell on the rock wall or something! So don't try to touch the rock (P.S. The rock is either sharp or slippery, and it will fall if you step on it). In another case, the water is diving and there are corals below. You dive into ............ because the water is too shallow. When you swim hard or try to stand up, your legs are easily scratched by coral. ......

Coping method

A. Please keep in awe of the ocean. Most students' understanding of the ocean is 0, and swimming well is limited to the pool environment!

B. don't go into the water when there is a storm in the rainy season.

C. don't just look down at the fish and swim farther and farther unintentionally.

D. All students who can swim, please buy flippers! The driving force of human feet in seawater is too limited, and flippers are life-saving tools when encountering strong currents!

Trust your instincts. When you feel dangerous, don't be afraid to lose face and shout for help.

2. Ships and propellers

In this case, when you jump off the boat at the snorkeling point, don't bury your head in the fish! Please look up from time to time to see where the ship is. This doesn't mean that the boat left or drifted away, and you were thrown away ... It means that the boat easily drifted to your side, and then you hit ...................... head on. (At present, students' legs have been scratched by the propeller of the ship. Please pay attention. )

Response: Don't be silly, keep watching the fish! Looking up from time to time: a. observing nearby obstacles; B. observe the distance from the crowd/shore.

3. Mask and breathing tube

Before using it for the first time, please feel it in shallow water or even in the hotel swimming pool! Don't realize that your first time was directly in deep water! Because most students choked on water at first because they didn't master it well, the feeling of choking on seawater was really bad ... so we should adapt to it in fresh water first! You must wear a mask and don't let your hair get stuck. Although the hair is thin, it will also make the mirror water.

You must buy your own breathing tube ~ in fact, I suggest you buy it with you. Suitable size, hygienic, and inexpensive ~ you can buy it from the local small commodity market.

4. Coral scratch, shell scratch and sea urchin perforation

Stabbed by sea urchin, as I said, I have been stabbed, and one foot may have been stabbed more than 20 holes. At that time, the tour guide patted it with a hard object and soaked it in vinegar. Almost all the soles of the feet are fine, except for a very shallow trace. However, I can still see the black stab marks on my heels, and it hurts a little when I walk. When you see jellyfish, you should avoid them quickly, which may be fatal.

A. Swimming in shallow places (such as not noticing low tide) or swimming badly, your knees are easily scratched by corals or oysters when kicking water, and your calves are scratched when catching lobsters;

B. Many students can't swim, so they walk in the water ... Of course, they can't see anything in the clear water ... There may be many scratches on the shells, especially the pointed shells on the small stones ~ ~ Sea urchins are more in Southeast Asia, but they are generally in deep places ~

Coping methods:

C. Please swim around the coral-please don't try breaststroke above the coral ... You must be scratched ... and the coral will get hurt. People only grow 5cm a year, and the coral will die.

D. If you are sure to walk in the water, please wear shoes or diving socks, but whatever you wear, please look down in the mirror first to see what is in the water! ! ! ! ! Coral can't step on it, for the same reason! Sea urchin, if you hit 90 degrees ... you can't wear anything! If you step on a strange fish and get bitten, it is inevitable. If it is a sea snake, I dare not think about it.

E. Go snorkeling at sea & flip! ! !

The flippers are a double-edged sword. On the one hand, if the water is shallow, you try to stand up and walk ... then the flippers will be very laborious, very easy to sprain your ankle, and very easy to throw away ~ but on the other hand, if you go deep into the water ... or the waves are a little big, please wear flippers! Because flippers increase the driving force ... why do you say that? More than one classmate mentioned that when going snorkeling, a bunch of people went into the water to play with each other, and then when uploading, LG couldn't find LP, or vice versa, and then the other party swam desperately in the water (it was really hard, and you would die if you didn't fight) ... but it felt like you couldn't get close to the boat ... and finally you would swim back.

. . The conclusion is. . . . . The flippers are really useful! ! I got on the boat with the help of a pair of colleagues.

I'm sure you won't be stupid enough to go alone! This is how novices commit suicide.

Advice to students who can swim:

1: Never overestimate yourself. If the water is not good, please put on your life jacket.

2. Ask the local people whether the waters are safe before launching. The sudden waves in many places are beyond your expectation.

3. It is very important to use breathing tube. Don't take the breathing tube out of your mouth easily, and don't take off the frog mirror, even if it has surfaced or choked on water, otherwise it will be easily swept away by the waves. Learn how to empty the breathing tube by forcibly exhaling. If possible, please try to choose a dry test breathing tube to prevent water from entering. The flippers can help you swim back to the shore for a long distance when being hit by the waves, but please pay attention to walking backwards in shallow water to avoid it.

5. It's normal to choke when playing with water. Don't panic, keep calm and drainage, and keep breathing is king.

6. If you like to dive into water several meters deep without wearing a life jacket like me, you sometimes need to know how to balance the ear pressure. In addition, taking two or three deep breaths before diving helps to empty the residual waste gas in the body. After taking another deep breath, you will find that the diving time will be at least half less than usual, but it is not easy to do too much rapid breathing, otherwise the adverse effects will be very dangerous. Anyone who has taken the OW course should know this, right?

It is best to take a 1 long sleeve T-shirt for a day trip. We just brought long-sleeved T-shirts in addition to swimsuits and short-sleeved T-shirts, and put on dry long-sleeved T-shirts as soon as we got off the speedboat, so that we could feel warm immediately and wouldn't get sick from freezing.

The following are very important tips, don't miss them:

Jet lag/seasickness/carsickness/venous thrombosis

Time difference: drink more water, juice, take vitamins, and don't drink coffee ~ ~ Your body will adapt quickly.

Motion sickness/seasickness: You can only take motion sickness medicine ... It should be reminded that the side effect of motion sickness medicine is drowsiness ... life. ....

Venous Thrombosis: Pay attention to this. Be sure to untie your shoelaces on the plane, then get up every 1-2 hours, stand up and drink plenty of water. Don't lie still, it's not good for your health. Of course, diving in Sanya will not be used, but you must pay attention to some places abroad.

suffer sunstroke

Reason: There is nothing to say about the reason, just an exciting stroll at noon; Symptoms include weakness, irritability and nausea. Summer in Sanya is very common.

Prevention: 1 1 Play at the seaside before 8: 00, go shopping/do spa or nap at noon, and come out after 3: 30 pm ~

Treatment: lying flat with a fan should be able to recover soon. It would be better if you could drink some salt water (many students have a good habit of bringing small kettles and small bags of salt).

Skin sunburn

Reason: Because of humidity and ultraviolet intensity, the seaside is very easy to get sunburned. Even if it is cloudy, the skin will be red, swollen and burning after sunburn, and it will hurt to sleep in bed at night ... which will lead to poor rest and affect the travel mood. ...

Prevention: 1. Be sure to use the strongest sunscreen, SPF50+, and it is recommended to press sunscreen;

2. Repaint after each swimming/snorkeling;

3. 10-2 Avoid sun exposure ~

When you come back at night, you must use the sun to repair it. Banana boats or bees are ok ~

Sunburn: There seems to be no good way. Soak/apply cold water and apply aloe vera gel. ...

diarrhea

Reason:

1. Eat unclean fruit;

2. Drink too much coconut milk, etc. Coconut milk is cold, you can't drink too much, and eating seafood will definitely have diarrhea ~);

Step 3 eat spicy food continuously

Prevention:

1. Don't buy peeled fruits, especially those soaked in water;

Don't add ice to your drink. Ice may not be made of clean water.

Scratched and cut by coral

Reason: The stone by the sea looks smooth, but don't touch it or breaststroke in shallow water. The small coral on the stone is super sharp, and it basically hurts when touched.

Prevention: 1. Wear diving gloves and flippers; 2. Go snorkeling and swimming ~

After injury: rinse with clear water and then put on a band-aid. Coral cuts while diving can easily infect your wounds. If there is infection (aggravated pain, redness and even suppuration), please go to the local hospital immediately, and don't delay ~

Jellyfish sting

Reason: Most jellyfish in Sanya are not dangerous, but they have been seriously stung.

Prevention: 1. If it is a jellyfish tide, the hotel/diving shop/local people will tell you, so don't go into the water at this time; 2. If you find jellyfish nearby ... don't venture into the water; 3. If you go in the rainy season, especially when swimming in some shallow spots, you can consider wearing a diving suit and pass it to your upper body ~

After injury: 1. Pour vinegar into the injured area to neutralize the toxin (of course, without vinegar, countless American dramas have taught us to urinate in this case ...); 2. Avoid the wound from entering the sand; 3. Go to the hospital at once ~

Finally, we must keep awe of the sea, act cautiously, avoid unknown creatures and feel that we don't know the situation. Think again and ask someone when you get back to a safe place. Diving itself is a very dangerous activity, and snorkeling at night increases the danger. Although the underwater world is rich and colorful, you should always be vigilant.

Be sure to trust your intuition, leave immediately when you feel danger, and shout for help.

I saw many strange creatures in the sea of Sanya. Sea snakes, red jellyfish and small sharks are all dangerous. Although the danger of small sharks is not so strong, we should remain vigilant. Many small fish are safer when they are together, and suddenly they find that all the small fish around them are gone, so you should pay special attention when you are alone.
