Health Benefits Of Scuba Diving

We all know that Scuba Diving is a very enjoyable and relaxing sport, but did you know that it is truly good for your health…mind, body and soul? Here are 6 key factors that show why this is true:

1. Physical Fitness

There are many reasons why Scuba Diving increases our overall Physical Fitness. Scuba diving on a regular basis steadily improves and maintains your general fitness and stamina levels. Exercising in water is very effective due to the natural resistance water has against our bodies especially when we kick our legs to fin and propel ourselves in the water. It has been shown that scuba diving for an hour can burn as many as 500 calories, making it just as beneficial in terms of calorie burn as working out for an hour on a cardiovascular machine in the gym.

Because divers have to be able to support the weight of their scuba gear when moving on land, they are constantly building muscle tone in their legs and back.  Increased muscle tone helps in relieving tension and improves ailments such as backache because, by strengthening the back muscles, pressure is reduced in the spine.

2. Meditative Breathing

Slow, deep breathing is important in scuba diving to optimize air consumption and bottom time. An added bonus is that deep, steady breathing promotes a calm attitude and reduces the risk of a lung-expansion injury.

Similar to breathing during meditation, breathing slowly and deeply while diving induces a calm, relaxed state while the diver focuses on the underwater environment rather than thinking about problems they may be experiencing in daily life. This helps to reduce stress and balance the nervous system. A relaxed, calm state of mind has been proven to promote a positive attitude and prevent depression.

Deep breathing also means increased oxygen intake and this has numerous benefits too. Increased oxygen levels in the body raises energy levels, stimulates circulation, benefits heart and lung function and improves mental capacities. When there is sufficient oxygen in the body the need for intoxicants and stimulants diminishes.

3. Warm or Cold Water Adventures

Taking a vacation and getting away from daily stresses will improve one’s mental health. In addition, the majority of divers when planning a diving holiday choose warm, tropical climates where they are exposed to more sunlight than usual.  One of the most important benefits of sunlight is that it supplies the body with Vitamin D which has many health benefits including increased absorption of calcium which strengthens bones. It also increases endorphin production in the brain which makes us “feel good.”

Diving in another country brings other benefits too. They say that travel is the best form of education and most people relish in the experience of visiting new places, experiencing a different culture, and all the new sights and smells and tastes that go with it. Dive travel abroad also means you are likely to meet fun people from all over the world with whom you have a common interest. Have you ever noticed how people tend to be happier and friendlier in a warm climate?

4. Healing Effects of Water

Often times people are submersed in water to calm down or to be healed. Water has a way of making us feel healed and restored.  For example, watching fish in an aquarium has a relaxing affect on the mind. Compare that to actually being in that underwater environment and those calming effects are intensified. This is one of the reasons divers keep going back for more. They find it a great way to unwind, relax and forget about all the stresses of daily modern life.

When divers are underwater, they are at the mercy of the ocean currents and surges. The very act of surrendering to this force instantly calms the body and allows it to flow just as the marine life does so naturally. Rather than fighting against the natural flow, this act of surrender induces a calmness and feeling of being at home in the underwater environment.

5. Marine Life Encounters

Connecting with marine life takes the health benefits of diving to a whole new level. Just as pet owners feel good when they interact with their household pets, interacting with marine life creates a connection that most divers will never forget. The pure pleasure, wonder and awe of interacting with and being up close to amazing marine creatures produces a feeling of increased well-being. This feeling is heightened when we have an encounter with a species we feel a certain attraction to, or particular respect for, such as sharks or sea turtles.

Marine life encounters increase one’s awareness of the environment and how critical the health of the ocean is. Millions of life forms depend on clean, healthy oceans, and marine life interaction deepens the conviction for divers to make a difference in their daily lives to benefit the oceans.

6. Social Health Benefits – The Buddy System

Scuba diving means you need to learn to be responsible for both yourself and your buddy and to look after your own safety. You will learn to stay calm at all times and that can help you during stressful situations in your every day life.

When you dive, you meet other like-minded people who often become good friends as you all share that common interest. It’s easy to make friends among divers as you will find a sense of community among them. It’s an exhilarating feeling to surface from a dive full of wonderful memories of your experience and then to be able to talk about and share them with good companions who are just as excited as you are!

 

 

Get ready for the 2014 dive season!

The 2014 dive season is underway and if you aren’t ready to grab your dive bag and head off for your next exotic location, what are you waiting for?

Before you strap on your gear, be sure that you are completely prepared for another season of underwater adventures.  It takes more than the right gear to get you ready for everything the water will throw in your direction. Your body must be prepared for rough conditions as well as the physical and lung strength it takes to successfully complete a dive.

Don’t get out of shape during your off-season. Before you plan a dive, get a quick health and fitness assessment to ensure that you are safely taking the plunge. You may not have to be in Iron Man shape, but it is important to not have any injuries or health issues that may affect your ability to dive. Consult a medical professional to give you the green light if you have recently had any changes in health. Diving will give you a good workout, so be sure that your legs, glutes and core are ready for the journey.

Another item you will want to check off your list is your equipment. Be sure that it is in peak condition and ready for use. You may want to have your equipment professionally serviced to ensure its safety. An equipment failure is not something to take lightly and can be prevented with regular service and care. Follow the manufacturer’s recommendations to ensure that your gear will continue working like new with every dive.

If your body and equipment are ready to go, make sure that the skills required are fresh in your mind. Brush up on important information, or even take some courses to learn new skills. There are endless opportunities for growth in the diving realm, and PADI offers numerous certification courses that will expand your horizons and make your diving experience even better.

Contact your local PADI Dive Shop to take a course, get a quick scuba review, or find where you can service your equipment before you start the 2014 season.

NIGHT DIVING: RULES, RECOMMENDATIONS AND FUN FACTS

If you feel that scuba diving is a thrilling exercise, try night diving. It is quite an interesting and mysterious experience. Once you descend into the water at night and discover a whole new world, you will definitely want more.

SURPRISESOR FUN FACTS

Night dives are always full of surprises. Let’s look at a few of them.

Diving at night at a location which is very familiar to you will present you with a completely new experience.

Night diving definitely changes the way we see marine life.  At night the marine world appears to be more beautiful, colorful and mysterious.

The experience and calmness of night diving cannot be compared with any other form of scuba diving. It is completely different. Dive slowly at night and you will find it exciting and relaxing at the same time. Many of the reef animals sleep during the day and only come out at night.

For example, wide ranges of fish can be seen sleeping in small holes. Likewise, many different shrimp, lobsters and crabs show up at night. You can also be so lucky as to see sharks passing by at the end of your light. Thus, there is indeed a chance to discover new and exciting marine animals while diving at night.

Bioluminescence is something you have to experience during a night dive. There are tiny plankton type organisms underwater that give off a bioluminescence at night when set in motion.

To see it, try to minimize the effect of your flashlight and move your arms around in the water. This will make the plankton light up like tiny flashes all around you.

This can only be seen in darkness so you will need to cover your flash light. It is not recommended that you turn it off, simply cover it against your stomach or hand.

RULES AND RECOMMENDATIONS

Planning should be done carefully for night diving. There are a number of factors to be considered before you go underwater in the dark.

When choosing where to do a night dive, it is a good idea to pick a known site. It will be easier for you to navigate around at a dive you are familiar with from a previous day dive.

You will also be able to see the massive changes that happen when the underwater world goes from day to night.

When choosing a dive spot keep in mind that you do not want anything uncontrolled happening at a night dive.

Therefore, pick a dive spot with as little current as possible, and no surf or other obstacles that can interrupt the dive.

You also need to make sure that the spot you choose is easily accessed when it is dark.

Easy entry and exit is important, especially if you need to carry your dive equipment.

EQUIPMENT

Wen-ho Yang

It is important that you set up all of your dive equipment during the day or in sufficient light prior to the night dive. This will ensure that all of your equipment is set up properly, and that you will not forget anything.

You need to use a dive torch with strong power and long battery life. When choosing a dive light you should consider the beam width, burn time and the depth rating.

Always keep a spare flashlight in case your primary light runs out of batteries or stops working.A small flashlight can be stored in the BCD pocket.

It is also a good idea to have a chemical light stick or a battery powered marker, which can be attached to your BCD or tank, for easy recognition. The light can also be attached to the boat, anchor line or buoy so you can find your way around.

Use familiar equipment that you have tried during a day dive. Do not go on a night dive with brand new equipment that you do not know how to use.

TIMING

It is a good idea to go diving at twilight, this will make it easier for you to adjust to the darkness gradually.

Another adventurous option is diving down just before dawn. It is unbelievable to watch the beauty of marine life when they awaken.

Plan for a shorter dive, compared to daytime diving, for safety reasons.

GET A BUDDY

Getting a buddy for a night dive is a must. It gives you great mental support. Keep in mind, however, that you and your buddy need to keep an extra eye out for one another. It is easy to get lost at night.

You can also use a short buddy line to minimize the risk of being separated.

Be careful where you point your light. It is a good idea is to keep your light facing down toward the bottom so as to prevent shining it in other divers’ eyes.

SIGNALING

Learning to use light signals is crucial for a night dive. For example, moving the light up and down is for attracting a buddy’s attention. Waving from side to side indicates that something is wrong.

Waving the light in a circle shows that everything is fine.

Making a signal while holding the light toward your hand helps other divers to see it better.

BEFORE YOU GO

The first time for night diving should always be with an instructor.

Depending upon the training agency, it can be done through different courses.

Once you have had that experience with the instructor, you can make plans to go on a night dive with your buddy or on a holiday night dive with a dive center.

GO FOR IT

Night diving can be a breathtaking and fascinating act. So what is stopping you?

Go on and try this adventure to get a new feel for scuba diving all over again. Even if you are not new to night diving, there is always more to discover.

Every time we dive underwater at night, we can find something new to explore.

Some quite interesting facts about diving

Reflex

Hold your breath and submerge your face in cold water and your heart will immediately slow down by as much as 25 per cent. This is known as the “diving reflex” and it’s something we share with other mammals. It means we can survive longer without oxygen submerged in cold water than we can on dry land. Although it is an instinctive reaction, it can also be trained: free divers (the sport of deep diving without any breathing apparatus) practice the art of meditation and deep breathing in order to slow their heartbeat.

The deepest free dive ever achieved (using fins) is 896ft (273m), reached by Croatian diver Goran Colak in Lignano, Italy, in 2011. The record for holding one’s breath under water (static apnoea) is held by Stéphane Mifsud, a French free diver who managed 11 minutes 35 seconds in 2009.

Deep

The record for the deepest any human has ever dived was set in 1960 by Jacques Piccard, and his assistant Don Walsh, in an area of the ocean called Challenger Deep, part of the Mariana Trench in the Pacific. The trench is 1,580 miles (2,550km) long but only 225ft (69m) wide, and reaches a depth of about 6.8 miles (11km). It took them four hours and 48 minutes travelling in Trieste, a pressurised bathyscaphe (Greek bathos, “deep” + skaphos, “vessel”) in 1960. According to Piccard, “the bottom appeared light and clear”. In reality, the pressure there is so great you would have to heat water to 530C (986F) to get it to boil. In 2012, the film director James Cameron followed in their footsteps, and reached roughly the same depth in around 70 minutes.

The life aquatic

Aquatic mammals have used the reflex to allow incredible feats of underwater endurance. The sperm whale can dive the deepest of any air-breathing animal: they’ve been identified more than a mile (2km) down for around two hours at a time, where they hunt for squid. They expel all the air from their lungs to avoid the risk of “the bends” and survive on the oxygen absorbed in their blood. They can dive the length of a football pitch every minute.

Elephant seals can dive for two hours at a time, and reach depths of 5,000ft. Their bodies hold twice as much blood as most mammals and, when they’re diving, their heart rate plummets from 90 to just four beats a minute. To help them sink faster, some will even swallow stones.

Clear vision

A seal’s eyes don’t go blurry underwater. In other mammals, this blur is caused by the outer lens (cornea) being rendered useless by the water, like a transparent glass marble which disappears when you drop it in the bath. Seals overcome this through a huge spherical inner lens to focus the image, and an extremely adjustable iris to control the light. This not only gives them their big-eyed charm, it also means they can hunt in bright sunlight as well as the gloomy ocean depths.

Feathered divers

Gannets have no nostrils. Because they dive headfirst into the sea – hitting the water at 60mph – and need to keep water out of their lungs, the birds breathe solely through their mouths. They can dive down to 25m (82ft) below sea level. Geese lose altitude by “whiffling”; they nosedive, spiralling as they go, sometimes flying upside down with their heads pointing straight ahead.

Plunging

In the St Louis Olympics of 1904 there was a very odd event called the “plunge for distance”. Competitors dived into a very deep pool and remained motionless until they bobbed up again. The winner was the one who sunk the farthest without attempting to propel himself through the water.

The gold medallist was an American – 20-year-old William Dickey – with a plunge of 62.5ft (19.05m).

Scuba fun

“Scuba” is an acronym for self-contained underwater breathing apparatus. In North Carolina, there is an annual underwater bike race undertaken by people in scuba gear. In the Maldives there is an underwater spa, where passing fish observe your massage; there’s also an underwater restaurant 16ft (5m) below sea level.

But the hotbed of underwater activity is Florida: the Lower Keys Chamber of Commerce stages an annual underwater concert which gig-goers can attend in their scuba gear; or you can get married underwater with a live video feed to guests on the surface

EN 250: What is it and Why is it Stamped on my Regulator?

EN250:2000 Respiratory equipment – Open Circuit Self Contained Compressed Air Diving Apparatus – Requirements, Testing and Marking is a European normative standard that was published in the year 2000, and Regulators must be independently tested to ensure they meet these minimum requirements. The purpose of this European Standard is to ensure a minimum level of safe operation for apparatus down to a maximum depth of 50 metres (164ft).

If you’re not sure what EN 250 means, you’re not alone!

You may never have noticed the unobtrusive lettering on your first stage, except to point out that it isn’t the serial number and move on.

So, what is it and what does it say about your regulator?

Manufacturers and consumers alike expect regulators to perform to certain specifications. If you purchase a travel regulator, you expect it to deliver a good performance under the conditions it was created for- in warmer water. However, most travel regulators are not designed to dive in all conditions; there are temperature limitations on many of them that would keep you from using them in Great Lake diving or under ice. Conversely, there are regulators that are diveable in more difficult situations such as high current or ice diving. But what exists to objectively test these regulators to ensure that they all perform under these specifications and conditions?

Enter the EN 250 rating. This exists to ensure that your regulator will perform well in every environment and condition for which it is advertised. It is given by a third-party testing facility (also designated on the regulator). EN 250 is an assurance that your regulator can deliver quality breathing performance beyond the recreational depth limit. In 2013, they plan to release a new rating requirement: EN250A. This rating ensures that your primary and your octo will simultaneously breathe easily under the same testing conditions. So, here are a few markings to reference on your regulator if you’re not sure what yours is meant to do.

1. <10 degrees C/50 Degrees F: Regulators marked with that designation should not be used in cold water. In other words, your local quarry during the summer may be fine, but don’t take it in Lake Michigan

2. EN250: Your regulator is designed to operate to 165 ft and below 50 degrees F with unchanged breathing performance in the first and second stage. The octo will not perform to the same specifications and its use is not recommended below 100 ft.

3. EN250A: Your regulator is designed to operate to 165 ft and below 50 degrees F with unchanged breathing performance in the first and second stage as well as the octo.

4. CE0078 (or some variation) is the stamp of the center that tested the regulator.

Additional Markings and Abbreviations (EN250A)

  1. Demand regulators which are not designed for cold water use are marked with ‘>10°C’ on both the Second Stage Demand Valve and First Stage Pressure Reducer.
  2. Demand valves which are intended to be used with an Octopus, shall be marked with EN250 followed by an ‘A’. EN250A.
  3. You may also see the use of a; symbol (Octopus) which also indicates that Apeks First Stage pressure reducers are suitable with two second stage demand valves and for use as an escape device by more than one user at the same time.
  4. If a demand valve is marked with EN250A, this demand regulator is suitable, tested and intended to be used in water temperatures below 10°C (50°F) and configured with an Octopus.
  5. If a demand regulator is marked with EN250A >10°C, this demand valve is suitable, tested and intended to be used in water temperatures above 10°C (50°F) and configured with an Octopus.
  6. If a demand valve is only marked with EN250 and not followed by an ‘A’ or the (Octopus) symbol is not shown, then it will not be suitable for use with an Octopus and is not intended for use as an escape device by more than one user at the same time, also known as an Octopus.
  7. You will also see CE0098. This denotes the identification number of the Notified body who has independently certified and examined your product.
  8. A serial number can also be found, usually comprising of eight characters, on both the first stage pressure reducer and second stage demand valve.

The PADI TecRec Range – When One Tank Is Not Enough!

The TecRec Range

Surface

Technical diving is scuba diving’s “extreme sport”, taking experienced and qualified divers far deeper and further than in mainstream recreational diving. Technical diving is marked by significantly more equipment and training requirements to manage the additional hazards this type of diving entails. Tec diving isn’t for everyone, but for those who want to be explore further, the TecRec courses are the answer.

Diver Levels

Most of the names of the courses in TecRec range include a number (eg Tec 40). This is an indication of the maximum depth in metres intended for a diver certified at this level. As a general rule, each course includes four dives. 

Discover Tec

This short session allows divers to give technical diving a try. It does not result in a certification, but lets a diver experience wearing the extra gear involved in technical diving and understand the rationale behind it.

Tec 40

The entry point into the technical range, Tec 40 provides a transition from recreational to technical diving. Although the use of full tech gear (doubles and wings) is preferred, it does allow modified use of recreational gear in some situations, provided the diver has two separate regulators, with one of the first stages fitted with a long hose. Double and single rigs

(For example, a main cylinder and pony cylinder combination). The intended working limit for a diver at this level is 40 metres/130 feet with up to 10 minutes of non-accelerated decompression. They may use any EANx mix with up to 50% oxygen content or air. To enrol on the course, a diver must be the equivalent of a PADI Advanced Open Water diver, with an EANx Diver rating and have deep recreational diving experience.

Tec 45

The diver must use full ‘standardised’ tech rig, including wings and doubles plus an additional deco cylinder (note that side mounted cylinders are an acceptable alternative to back mounted doubles throughout the TecRec range). The course allows the diver to go to 45 metres/145 feet and make accelerated decompression dives using any mix of EANx or pure oxygen. A diver must have the equivalent of a Tec 40 rating to enrol on this course.

Tec 50

This course represents a high level of competency for a technical diver. Although the option exists to make the last dive of the course using trimix, it is intended as an air/nitrox rating and by the end the diver can dive to a maximum of 50 metres/165 feet and make extended, accelerated decompression dives.

Tec Trimix 65

This course opens up the advantages of trimix to the diver, and divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression, using any trimix with an oxygen content of 18% or more. They can dive to a maximum depth of 65 metres/210 feet.

Tec Trimix

Trimix Divers

This course lets the diver go deeper, opening up the option of using travel gases and trimix with less than 18% oxygen content. Dives made during the course can be as deep as 90 metres/300 feet. Once qualified, the diver can start to explore deeper; for this reason there is no numbered suffix after the course title as in the rest of the range — there are no limits placed on how deep the diver can go after training, providing they build their experience gradually.

Gas Blender

Cylinders

The Gas Blender rating certifies the holder to mix enriched air or trimix for divers to use in recreational or technical diving operations. Courses for this level are conducted by Gas Blender Instructors.
