avoid any jellyfish protection creams - uselss and dangerous

As posted the Wicked Diving Website....Please copy and post

The season has begun and diving is great! However some unscruplous marketers are trying to exploit people's fears. Trying to sell divers, snorkelers and visitors some "magic cream" that prevents jellyfish stings - people can be put at risk of injury or death.

Avoid this cream, let any dive shop or retail outlet that supplies it know how they are endangering their clients and please avoid it at all costs!!!

If you think this is just opinion...please read the email below regarding this product. Written and signed by the world's leaders in Jellyfish stings, envenomation and the head of DAN. I guess they might know a bit more than someone who makes and sells magic creams?

Subject: FW: Marketing of Safe Sea in Thailand


We have been following the recent renewed correspondence about the proposed marketing of Safe Sea in Thailand. As you are aware, there are a group of us, including some well-known medical and marine biological jellyfish experts, who have been closely monitoring the situation with dangerous jellyfish in Thailand and we are all very concerned about the introduction of Safe Sea at this point in time.

Let us re-state some important facts:

1. There is definitely at least one variety of potentially lethal box jellyfish found in Thai waters. This includes the Chironex species as well as other chirodropids, currently unidentified, but probably just as venomous . There is absolutely no doubt about this as we have received good photographic evidence of these jellyfish, and have extensive evidence from numerous cases over more than a 20 years of the distinctive scarring caused by the stings of these particular jellyfish.

2. There have been numerous documented deaths caused by jellyfish in Thailand over many years: we currently have an article in print with details of a number of documented deaths and “near-misses”. The death of the Swedish girl last year was certainly not an isolated case, although to date it was the one that received the broadest media attention. We also have a steadily increasing number of case reports of life-threatening stings, including those with permanent scarring as well as those producing Irukandji syndrome.

3. Substantial experience from northern Australia over many years has shown the importance of effective prevention strategies. To date these have included the wearing of protective clothing, suitable netting, appropriate signage and education. As a result, despite the presence of large numbers of dangerous jellyfish at certain times of the year, there are very few serious stings.

4. The Safe Sea may have been shown to be an effective barrier to the stings of certain species of jellyfish. However, it appears that there is absolutely no evidence that it is effective in the prevention of stings from life-threatening box-type jellyfish, especially Chironex.

5. We are further concerned that even if Safe Sea should someday be demonstrated to be “as effective” for Chironex-type box jellyfish as it claims for other species (i.e., 75% efficacy, in reducing the frequency and severity of stings), this is still unacceptably high for otherwise unprotected exposure to lethal species.

In light of the above, we consider it to be irresponsible and dangerous to promote an unproven product in an area where the consequences of using the product could prove fatal. It is likely that tourists and Thai locals would be lulled into what could well be a false sense of security by using Safe Sea instead of taking preventative measures that have proven to be effective. Severe stings or deaths occurring without added protection of these preventative measures we suggest could have ongoing consequences.

Receiving FDA approval from Thailand does not indicate that the product is effective against Chironex-type box jellyfish stings and can be misleading in this context.

For all the above reasons we implore you to refrain from marketing Safe Sea in Thailand until such time that it has been independently demonstrated to be effective against the potentially lethal species found there and it is established that this product effectively prevents envenomation when interacting with these species.

Visit Thailand on long-term visas for free!!!

Get a fee-free Thailand visa until 2010

In an effort to help encourage Thailand’s travel and tourism industry, the Royal Thai Government has agreed to extend the exemption of the Thailand visa fee for tourist visa applications until 4 March 2010.

The exemption will apply to all applicants for a Thailand visa on arrival at all international airports in Thailand as well as those applying at Thai embassies and consulates abroad for stays longer than the period for which they are normally eligible.

Thailand currently gives a Visa on Arrival for citizens of 20 countries for a stay not exceeding 15 days. Citizens of another 42 countries are allowed a visa-free stay in Thailand not over 30 days.

Visitors who wish to stay longer than those periods have to apply for Thailand visas at the Thai embassies or diplomatic missions abroad before their arrival in the country.

The extension is one of several measures taken by the Thailand tourism industry to invigorate itself after a number of global and local events that have led to a temporary drop in visitor arrivals.

TAT Chairman, Mr. Weerasak Kowsurat says, “As a result of the global economic downturn, the worldwide travel and tourism sector has declined as people have become more cautious about spending on leisure and business travel. Hence, the government has implemented many measures to enhance Thailand’s competitive advantage and strengthen our country’s unique qualities.”

This offers a great opportunity to sign up for a 60 or 90 day visa. Stay in Thailand longer, do a Similan Liveaboard or even consider doing your Instructor Training!

Dive with Nitrox while in Thailand!

EANx diving has many advantages over air diving.
Some of the benefits are:
1. EANx, when used with standard dive tables or computers, provides a tremendous safety factor.
In fact, when utilized in this fashion, the actual nitrogen accumulation is that for a 10 to 20 feet (3 to 6 meter) shallower dive.
This application of EANx is ideal for divers who simply wish to be more conservative individuals who are not "as young as they once were" or those who may not be in the peak of physical fitness.
2. A significant increase in bottom time no-decompression limits.
3. A reduction of the possibility of decompression sickness.
4. A slight reduction in nitrogen narcosis.
5. A reduction of decompression time if the no-decompression limits are exceeded.
6. Reduced fatigue after the dive (declared by many EANx divers).

Learn to dive - Thailand's best places

Ever wonder what it would be like to jump into the water and look into the face of a passing turtle?? The underwater world is mysterious and yet inviting, the experience of diving it provides and addictive sense of zen. There's no better place to have your first dive experience than Thailand – with good conditions year round. Where to learn to dive in Thailand?

Most dive shops in Thailand offer PADI or SSI certification but it's also possible to find a few offering NAUI or CMAS. Beginners may be more comfortable diving in the calmer and shallower waters off the east coast of Thailand, with destinations such as Koh Tao or Koh Samui being the most popular on that side. The East coast has less marine life and coral though.

As the West coast has much better marine life and coral - you may want to consider this as your destination. However The weather makes diving unsafe from June through October. If you plan on visiting during this time - you will probably have a better time diving around Khao Lak and the Similan Islands. Hotspots for diving around here include Phi Phi and Koh Lipe.

Phuket has several dive operators to chose from, but the conditions near the pollution strewing island can be intolerable. Khao Lak offers an excellent choice of dive shops and also has a good range of accommodation to suit most tastes. It is also the closest jumping off point to the Similan Islands.

Phi Phi is quite popular among the younger crowd but there are hotels catering to older couples and families, which also offer scuba diving courses.

The Similan Islands, technically located in Phang Nga province, provide some of the best dive sites in the world. Protected within a marine national park, the nine islands are still pristine and rich with wildlife above and below the water. Most dive operators will take you ashore at one of the islands, where you can enjoy the powder-white beaches and see exotic birds and monkeys. Under the waves, the colorful reefs and boulder formations are teeming with coral and a variety of marine life. Sometimes whale sharks are even spotted in the waters, as well as rays and other sharks. Visibility is good, varying from 30-50m.

The best way to see the Similans is by liveaboard, and most dive operators will allow you to do your Open Water dives from the boat if you've completed the paper and pool work ashore beforehand.

Much like Phi Phi, Koh Tao is a fun place for backpackers to learn how to scuba dive. This may well be the most affordable place in Thailand to take a PADI Open Water course and to build up your dive log. Unfortunately it's not the best diving in Thailand – but it's not yet the worst either. Koh Tao used to offer frequent whale shark sightings but they are relatively rare these days. It's also conveniently close (2 hours by speed boat) to Samui. In fact you can do diving courses on Samui too.

The number of dive boats on a site is not restricted, so you may find there is too much company around peak dive times. You may find yourself surrounded by 50 to 100 divers at a time, with most of them being Open Water students or day trippers from Samui. Needless to say, Koh Tao might be great for learning and for progressing to instructor – but it's not all that great for just recreational diving. Many people come here specifically to advance through courses and proceed with PADI Advanced, Rescue Diver, Dive Master/Master Scuba Diver and Instructor courses.

There are so many choices on Koh Tao that you should look carefully at each dive shop and make sure they offer you the best value for money. Not all dive instructors are the same, and some are downright scary. Likewise, equipment standards can vary, and you'll want to make sure any shop you choose has quality equipment and maintains it properly and hygienically. You should also check into the insurance policy of the dive shop and enquire as to if you should purchase your own dive insurance for the hyperbaric chamber if you have an accident.

It boils down to this - you get what you pay for. If you think it's a bargain - it's not! Your life depends on well-maintained well equipment and good staff. If you would like to know where to learn to diving in Thailand?

Most the dive operations in Thailand are run by foreigners, which is just as well since Thais have a rather different approach to safety and responsibility, but you'll find yourself diving with plenty of Thai staff who are their usual friendly easy-going selves

Diving animals and breath holding

Nature has shaped through evolution they way animals behave. This means that some animals have adapted to feed in places where the rest of the animal kingdom living around them cannot go. This naturally then eliminates a large part of the competition from the food chain.

The Similan Islands have whales, dolphins, turtles, birds and many other non-aquatic species that dive under water

So how are they able hold their breath for so many minutes without losing consciousness or dying? First, let's revise some other physiological principles in order to understand more clearly what is happening.

The need to breath is felt when the carbon dioxide (CO2) level rises above a certain threshold. The CO2 will dissolve in the blood causing its pH to decrease, which is making the blood slightly more acidic. The sensors in the medulla oblongata (the base of the brain) will then "tell" the animal that it is time to breath again.

Oxygen (O2) and CO2 are carried around the body by the blood in two different ways. One is simply the fact that both O2 and CO2 can dissolve in the blood. This will account for a small fraction of the whole transportation process. The other method uses the haemoglobin, a protein present inside red blood cells. Both O2 and CO2 molecules have the ability to attach themselves to the haemoglobin, but the carbon dioxide has a much greater affinity to do this. Therefore, whilst haemoglobin can carry up to four molecules of O2 it carries a much larger amount of carbon dioxide, normally about 23 percent is transported in the blood. However. The main point is that in most animals the O2 reserve is solely in the lungs and the blood. Once this reserve is depleted, the animals will need to breathe again to exhale CO2 and inhale new O2.

Breath holding diving animals have the advantage of an additional mechanism which, relies on another very similar protein called myoglobin. This protein is located inside muscle cells. In humans it makes up for only a very small percentage of the muscle mass. This percentage changes drastically in the animals with the need to hold their breath and it goes up to 45% of the muscle mass in sperm whales, animals that can hold their breath for up to two hours.

How does it work? Simply the blood will carry O2 to the tissues and the extra oxygen that is not used "immediately" will be stored in the myoglobin more or less in the same way as in the haemoglobin. Once the animal is under water and can no longer breath, the O2 stock of the blood will become depleted, the myoglobin will then release its O2 in to the blood that will carry it around where it is needed. At the same time the myoglobin will "catch" the excess CO2 in the blood restoring to a level that does not trigger the need to breath. When eventually the animal returns to the surface to breath air, the myoglobin releases all of its stored CO2 and replaces it with fresh O2. The amount of myoglobin present in the animal muscles will determine the maximum time the animal can spend underwater.

The more the animal wants to stay under water, the longer the period it has to stay at the surface for the gas exchanges to take place. A dolphin needs to breathe a few times (about two to four minutes) to stay submerged 20 to 30 minutes. A sperm whale will breathe 4 or 5 times per minute for up to 15 minutes at the surface to stay two hours under water. Sea birds normally dive for 3 to 10 minutes according to the species they belong to and need to breathe for about 2 to 3 minutes before diving.
