Dahab the Mekka of Freediving
About Freediving in Dahab
Freediving is a sport with increasing popularity. It is synonym
with breath hold diving and when you start getting professional
lessons you will probably increase maximum depth and also how
comfortable you are at depths. When I first started training i
had problems reaching 10 meters, but after a week i was able to
reach 25 meters. When you start taking lessons you will probably
find out that everything you did before was wrong and potentially
harmful.
Dahab has become one of the most important places for freediving
in the world. It has held neumerous competitions and world record
attempts. Most important is the Blue Hole where you find the Arch
where William Truebridge freedived without suit, fins or assistance.
You can see the video here.
The Blue Hole is 110 meters deep and 150 meters wide and is a
center point in the Red Sea for water sports.
There are not that many freediving centers in Dahab, but the
one we use are a world famous one. It is led by Lotta Ericson
and Linda Pernelli. Lotta Ericson is a previous world record holder
in static apnea. In this freediving center you can find different
courses for all level from starter to competition diver.

The Theory of Freediving
The Body
The human body is a quite interesting fenomenon when it comes
to freediving it is almost as we have a programming in out brain
that takes affect when your face gets emerged in cold water. The
hart slows down and you release extra bod cells. The blod vessels
in your skin and large mucels constrict and this function reserve
the blood for more vital parts specially the brain and hart.
There is alot of things to consider when attempting a freedive.
The first thing is the theory and this is something you should
learn from a professional like in a freediving center. I was attempting
alot of freediving on my own for a long time and after some time
i think i was getting quite good without knowing that the things
i was teaching myself was holding me back and even putting me
in danger.
Breathing Properly
The first mistake i did was that i was hyperventing extencivly
before going down. The reson why i was doing this is beacuse this
is something i was told as a child from my swimming teacher and
then again when i was starting my career as a scuba diver. The
perpose for doing this is that you clear your lungs of carbon
dioxide. The carbon dioxide is a part of the respiratory system
thats triggers your breathing. When your levels of carbon monoxide
is high your brain knows it needs to take a brath, so when you
hyperventilate you trick the brain into believing that it does
not need to breath so you can stay longer underwater. The only
problem is that the sub-conciosness of the brain is probably smarter
then the concius part. The problem with doing this is that as
the preassures of gasses changes from shallow to deep and this
causes something called a shallow water blackout. You can pass
out at around three to five meters depth and that is the reason
why you should never freedive dive alone.
The second mistake i did is not really dangerous, but it makes
it alot harder to freedive. What i did was that i was inhaling
to deep so i had a full mouth of air when i was going down. This
might seem ilke the logic thing to do so you can bring more air
down. I noticed the effects of the problem with this, but i dident
know why i was having a problem. The stomack starts cramping up
and you feel quite uncomforatble as if you were chocking or like
when you have to through up on an empty stomack.
Equalizing and going down
There are also may different techniques for equalizing and going
down. When you go down you are firslaying flay down in the water
and you take your breath. Then you bend your uper body down into
the water. Follow up by lifting up one leg and you should start
to go down and this should happen quite effortlessly.
Equalizing is something you have to do because the preassure
is higher the deeper you go. The preassure will make the air in
your sinus compact and create a big preassure on it. This is a
bit painful but very easy to prevetn. Keep your mouth closed and
then you pich or block your nose and try to blow through it. Dont
blow to hard and do this before you feel uncomforatble keep doing
this for almost every meter or so. What happens when you do this
is that you take the air from your lungs and move it into your
sinuses so that you equalize the preassure that your sinuses are
exposed to.
This may sound a bit complicated, but im not really a freediver
and definetely not teaching this, but it illustrates that there
is a need for a course for beginners with an instructor. The tecneques
are quite simple and take short time to learn. I used long time
learning this on my own and it is so much better and safer when
you dont need to figure it out your self.

Specializing in a genre
There are several categories in freediving and they are called
disiplines. And there are two main categories.
Pool Disiplines
| Static Apnea - This is basically a test in a swimming pool
to see how long you can hold your breath. |
| Dynamic Apnea With Fins - In this dicipline they swim a
ceratin distance underwater amost like a sprint and they can
choose between bi-fin or monofin. |
| Dynampic Apnea Without Fins - As you might guess this is
the same as above but they dont have any fins. |
Depth Disiplines
| Constant Weight Apnea With / Without Fins - This is two
seperate disiplines, but they are the same only in one you
get to wear fins and the other you dont. You follow a visual
referance without toutching it and follow it to a ceratin
depth. You are not allowed to drop any weights during this
disipline. |
| Free Immersion Apnea - The same as above in may ways, but
in this you use the referance line witch is most commonly
a rope to pull your self down. |
| No - Limits Apnea - This is kind of like a maraton where
everyone is free to use steroids. You can go bouth up and
down by any means nessesary. So what most people do is to
go down with a weighted sled and then go up with a air filled
baloon. |
| Variable Weight Apnea - This dicipline is a bit more toned
down, but you can go down with a weighted sled and return
by pulling your self up by the rope. |
