Ever wondered if there is a natural way to 'cheat' at freediving?
​This could be the answer! The studies seem to prove it. Watch the video to find out more....

If there is one aspect in the sport of freediving that gets the most overlooked by new freedivers it has to be ear equalisation. Many people start freediving expecting it to be the physical breath hold or mental capacity to deal with being underwater to be the most challenging aspect of the sport, and are often surprised when it is actually  equalisation of the middle ear that proves to be the challenge. Because it’s just as simple as pinching your nose and blowing, right?

Well not exactly. Firstly lets refresh and look at Boyle's Law as to why we need to equalise our ears during a dive. On an airplane you can get away with a simple blow against a pinched nose (or sometimes just swallowing!) to help compensate for the change in pressure in the cabin, this because the pressure change in an airplane is relatively very small. In scuba diving, the other place where you might equalise your ears, you can descend slowly, come to a head up position (which makes it easier), wait some time for it to work (and breathe!) before carrying on. In freediving we are descending fast in a head down position which makes the whole process more difficult if not done correctly or efficiently.

So here are the six most common mistakes of equalising for freediving that I encounter with my students as a professional freediving instructor:

1) Not being relaxed: 
Suddenly finding yourself upside down underwater and holding your breath is not conducive to being relaxed! Then trying to add another complicated skill (equalisation) makes things even more difficult.
Solution: Practice breath holds dry to get used to that sensation and the urge to breathe. Practice pool dynamics or statics to get used to that sensation in the water. Use muscle relaxation exercises to give you greater awareness of your body and how you hold it.
 
2) Descending too fast:
The quicker you descend the quicker you need to equalise. Fine if you are proficient at it, otherwise it can be hard to keep pace.
Solution: Slow down the descent speed, use the discipline of Free Immersion where you can stop or slow easier using the line. Remember that as you get deeper you will become negatively buoyant so will still descend without even kicking or pulling.
 
3) Using the incorrect or an inefficient equalisation technique:
FRENZEL technique (not VALSALVA) is the best method of freediving equalisation. Some people do it automatically, and some people need to learn it.
Solution: Learn Frenzel technique and figure out the best tongue position that works for you and how to control the ‘gates’ (soft palette and glottis). You can do all of this away from the water.
 
4) Not equalising frequently enough:
Freediving equalisation has to be done fast so you need to be ready so as to do it as often and as quickly as possible.
Solution: Keep your fingers close to your nose ready to pinch quickly when needed. Equalise in a rhythm pattern in anticipation of greater pressure coming up, not just waiting to feel pressure before reacting to it, which will prove too slow.
 
5) Not equalising the mask:
The mask often gets forgotten as an airspace and needs to be equalised via exhaling through the nose. If not done this can have a knock on effect to the ability to equalise the ears.
Solution: Exhale into the mask when you feel the pressure on the face increasing with depth.
 
6) Not training or practicing:
As with any skill, ear equalisation takes time to master. The control of the parts of the body involved does not often come naturally (who knew before how to ‘close your glotis’!?!). But practice makes perfect! You can’t expect to be good at something without practicing it repeatedly.
Solution: Learn and practice, practice, practice! Fortunately most ear equalisation training can be done dry so you can practice any time before even getting in the water. Doing a little bit of training every day will pay off greatly in the long term.
 
I hope this topic has provided some insight and will help you on your freediving journey! Of course the best way to learn a new skill is with an experienced freediving instructor that can observe and correct any mistakes and offer you correct advice and training solutions.

You know that feeling. You've just flown out for your annual holiday to the dream destination and you have been planning this trip for the past year. Warm blue water awaits you, long fins at the ready, and then you feel it. The soreness at the back of your throat and the tickling in your nose....the cold you dreaded is here! Pretty much a disaster for any freediver on holiday
After suffering one recently I thought I would answer and look at a few of the questions and myths around the common cold:

Are you are more likely to catch a cold on a flight?
Yes. But it's not the circulating air on the plane as most people think. Simply being in a confined space with so many other people, increases the risk of germs spreading. ALTHOUGH, re-circulated air is more likely to give you sinus problems (another issue for freediving). Also, low humidity in the pressurised cabin increases the risk of infection.

Why is a cold a problem for freediving?
The cold virus is attacking the membranes of your nasal passages and your sinuses which makes them swell up and increase mucus production. This clogs up the sinus passages causing increased pressure and pain. During a dive air in the body expandes and needs to be able to move which it can't do as easily if these passages are blocked.

So we know there is no cold cure, but what can decongestant medication do?
As we all know, there is no cure yet for the common cold. Antibiotics will only fight bacteria, not viruses. Decongestants (tablets or spray) can shrink the swollen blood vessels in the nasal passages, lessening the pressure and helping with drainage.

Is it safe to freedive using decongestant medication?
​Most research and advice on this topic is related to scuba diving (diving and descended under pressure for 30-45 minutes at a time). In scuba it is possible for the medication to wear off in that time causing problems on ascent. Freediving has different issues, most notably faster ascents and a lack of time to be able to stop and react if a reverse block (sinus pressure increasing from expanding air on ascent that is unable to escape the nasal cavity) occurs. Generally speaking it is risky, and anyway, if you are sick with a cold your body is fighting the infection and so is weaker and will therefore not be transporting oxygen as efficiently. Therefore you wont be feeling great and should not really be undertaking strenuous activity or pushing your limits!

Are there natural solutions for reducing congestion?
Inhaling steam such as in a hot shower or from a bowl of hot water. Adding an essential oil such a eucalyptus which has anti-inflammatory properties, can help. The hot steam dilates the blood vessels allowing increased blood flow and circulation, alleviates soreness and inflammation and liquifies mucus secretions making it easier to clear. Keeping hydrated also will allow the body to fight the virus quicker. Nasal irrigation such as a 'Neti pot' allows you to wash through the sinuses but this must be done with sterilised saline water and sterilised equipment and might feel uncomfortable if you are not used to it.

Any other options?
Snorkel!!! Most of the colour and marine life is in the top 0-10m of the sea, so you can still experience the wonder of being in the water and make the most of your holiday, even if you cannot dive down :)

Finally the wind has died down after what seemed like weeks of relentlessly strong wind which made the water choppy and a bit uncomfortable. Today was beautiful conditions and great visibility out at Lighthouse dive site, Dahab. 
Lyndsay's Level 3 course was going wonderfully (Dynamic 75m PB!) until suffering some inflamation to the middle ear after FRC mouth-fill training :-( So unfortunately it will be a few days resting out of the water for her, but no doubt she will be back stronger than before!
Tomorrow.......... BLUE HOLE and a bit more depth training, not to mention the chance to snorkel at 'El Bell' (video coming soon?!?).
