Who’s been in this month

Hi to all,

We have had a busy month with lots of people coming to dive with us,

First we had Andreas from Germany do a couple of guided dives in Alcala and El Puertito, IMG_4828and then  Sascha and Vlada from Belarus in with Bernard from Belgium, they loved seeing Jose the Turtle.

 

Bernard then went on to dive “El Raton” and Las Eras.

Then we had Eugen and Natalia from Germany with Eugen doing DSCF2168some guided dives and Natalia getting over her fear of being underwater and trying Scuba diving for the first time in the pool.

Then came David and Lorraine from Scotland, Lorraine to do her Advanced and David to do some dives, Lorraines main aim was to see a turtle but no Sharks… Well She got both Turtles and Sharks while doing her Digital Photography dive!

Well done to Lorraine as she passed her advanced course with flying colours and got a lot more confident as a diver during her time here.

Then in last week we had Vladimir, Georgi and Dina from Russia for a try dive, along with James and David from England. I had the pleasure of taking David and James, and I flooded my mask several times with the underwater antics of the brother in laws! Then we had Joel join us from the UK for a few guided dives

We had Sam, Ed, Nick and Jen – from sunny Silsoe (UK) (I got all the names right I think!!) in for a Scuba review and a very pleasant dive, again Jose didn’t disappoint and  came to see everyone, along with Ben, James and Bex who are still diving with us and looking forward to the night dive tomorrow.

Yesterday was a scuba review for Jerry and Sue from the UK, they had done the open water but hadn’t dived for 8 years, we had a fab day from start to finish, in the classroom, pool and ultimately in Open Water, we saw Julio the smaller turtle at first, and then Jose turned up for a tickle later on in the dive.

Today we have started the complete Open Water course with Graham and Charlotte, they are already doing great, and been in the pool for the first part of the open water course.

Tomorrow is an early start with Ben, James, Bex and Emma to get into El Puertito before the morning rush and the Open Water Course will continue with the Pool sessions 2 and 3 followed by the first Open Water Dive.

Happy Diving….

 

Why you need to wee more when you scuba dive

A question that was raised by one of our divers on a recent trip… Why when on dry land can I go for hours and hours not needing a wee, but as soon as I jump in and start a lovely dive then I need to go.

So I thought it was a great question and lets do some research, and there is a scientific reason why you need to wee more when you dive… it’s not just the fact you are in the most awkward clothes to get out of to have a wee !!

DSCF1626

So why do we need to wee more – I’m changing from my wetsuit to a white coat for a little science, first – what makes you need to wee..

The human body is full of blood. The volume of blood may increase or decrease with eating, drinking and other factors. The body regulates the amount of blood in the body in a very clever way – When the volume of blood in the body increases, the extra blood flows through the veins to the heart. The heart senses the increased volume of blood and nerve sensors in the heart tell the kidneys to release urine. This removes fluid in circulation and reduces blood volume.

So – what does Scuba diving have to do with it..

Cold Water & Gravity

  1. Cold Water immersion diaereses – This is the bodies automatic way to minimize heat loss, when you get into the water the body reacts (called the mammalian reflex) and sends blood to the vital organs so therefore increases the amount of blood in the heart and this starts sending signals to the kidneys to make you wee.. that pesky heart!

    Did you know as soon as you put your face in cold water it can drop your heart rate by 10 – 20% (and free divers train to drop it to even 50%) – I always wondered why my mother-in-Law splashed the kids face with cold water to calm them down when having a tantrum.. there is actual science behind it!

  2. Gravity – or lack of it – Weightlessness or near weightlessness,
    also causes blood to shift Paradise Divers - 11Jun2014 (16)towards the body’s core, This fluid shift was first observed in astronauts, who had to wee more than normal while in space. If you have perfect neutral buoyancy, it is like you have defeated gravity, and thereforeHover the blood collects around the heart, and like cold water immersion diaeresis tells your kidneys to make you wee.

 

 

So needing to wee when you are diving is NORMAL – it’s your bodies way to protect itself – you and I both know we don’t need our body to protect us from Scuba diving, but it doesn’t think being under the water for an hour is normal so makes us get out to wee

There is no way around it, I always encourage divers to go before they dive to try and reduce the impact. It is still really important to drink water, (avoid drinks with caffeine as this is a diuretic so will also make you need to wee) being dehydrated can increase the risk of DCS, give you headaches and increases cramps.

So there is no magic formula to make you need to wee less while diving, if you have your own wetsuit or semidry (a semidry tucked into your boots is very good at retaining the liquid inside it..) and you need to go then it’s your choice if you wee in it… make sure you rinse it thoroughly and yourself as well, it is 95% water.. but it’s still wee.

If it’s a rental suit it is frowned upon to wee in it – although all ours are dunked in a disinfectant after every dive, its still not pleasant for the next person.

If it’s a drysuit (and you don’t have a pee value) just don’t do it – you won’t have any buddies left who will unzip your suit, or share the car journey home!

From now on you know that it is normal that you need to wee when you dive – every diver feels it, it’s not just you getting old and incontinent, it’s your pesky body sending blood to the heart that makes you wee.

Happy Diving

 

Debris removal from our coastal waters.. Project Aware

We have recently been noticing more and more “things” underwater….

We love to see Sting Rays, Garden Eels, Groupers, Scorpionfish BUT we are not talking about marine life this time, we are talking about the fishing lines, the bags, plastics, clothing etc..  We have started to collect debris from our coasts and we have registered with the Project Aware movement. We are recording all debris and many Dive Centres are doing this around the world. Have a look at the current debris counters worldwide: It is obvious that we have an issue and who are the people that can do something about this…..Divers

Capture..

You can view our profile on Project Aware, and check out our “I dive against Debris” Badge. http://www.projectaware.org/diver/paradisedivers-0

Can anyone do this…?  Of course you can, grab a mesh bag and stick it in your BCD during your dives, when you see something that shouldn’t be there that could be harmful to marine life pick it up, and discard of it safely on land. Then register your findings on the Project Aware website so they can track and analyse all the information uploaded.

Focus

Project Aware are focusing in on two major ocean issues –Sharks in Peril and Marine Debris in our ocean. There are many conservation issues converging on our ocean planet at once, but they are concentrating on these serious problems where scuba divers are uniquely positioned to directly and positively affect real, long-term change in these two areas.

Scuba Diving – Tips for a better Dive

We get so many divers coming through our door saying how to improve their diving as they do not feel comfortable etc.. Well we have added some back to basics tips below which many divers forget about.. Some of this some of you would have not remembered from your Open Water courses and some of you will but this should be a good reminder for everyone.

1. Keep hydrated, especially in hot weather, at some point in your dive there will be strenuous activity, normally donning the equipment,  with an exposure suit on it will cause a sweat (even in cold places) so its very important to keep drinking.

2. Equalize often- The first thing you are taught is about equalization, but with everything else going on (turtles above your head etc) many divers forget and realize too late,  they then feel they can’t ascend back up to equalize when the rest of the group is going down. Often people give up quickly without giving it another try, if you have problems go up, signal to your buddy (Rattle or tank banger will help in these situations) and try to equalize again, don’t force it and descend slowly, if you are wearing a hood pull it away from your ears – keep equalizing whilst descending. The most important is to not feel pressurized to carry on the dive if you are having equalization problems.. There will be another day and another dive which is better that the alternative.

3. Breathe – Again one of the first things we all learn but over time good breathing techniques can be lost, and we may skip breathe, or breathe shallower, this can lead to an increase build up in carbon dioxide which leads to headaches and could even cause 000017blackouts. There are better ways of conserving air such as, improving your fitness, staying shallower, taking notice of your breathing, improving your weights and trim, keeping warm, breathe deeply & slowly from the diaphragm  and exhale fully. 

4. Take it Easy – We don’t scuba dive to try and get somewhere
quickly, there is no underwater race, we are all there to enjoy take it easy dudeswhat we see underwater. There is no point in rushing, take your time, look under the rocks, enjoy what is there – don’t just swim past and wonder why you are exhausted at the end of the dive. A good sign of you finning too fast is if after the dive you are wondering why you didn’t see that Arrow head crab, that cuttlefish hiding next to the rock etc.. If this is you, think about it next time you dive and you will find it is a better experience for you and your buddy.

5. Trim – Having your weights and cylinder in the wrong place can make a dive very uncomfortable, it just doesn’t feel right, everything is an effort and you use a lot more air trying to get it right underwater. This is where spending time in the pool adjusting your weights come in handy, in fact,  PADI has picked up on this and built triGoPro_print_10m into the revision of the open water course as it is so important. Perfecting trim comes with experience, but the best thing to do is to get your buddy to look at you or even take a picture, you will then be able to see what is wrong. The PADI PPB course is all about looking at Buoyancy and Trim so its a great course for helping and getting tips to getting it right.

There are lots of other tips available to improve your diving, these are just some of the main ones and what we believe helps a lot of our divers..

Happy Diving and enjoy the underwater world.!
