Approach to Relaxation
Learning to be aware of your breath and being in a state of relaxation is the best way for
a freediver to prepare oneself for a deep dive or just a long and enjoyable breath hold. In
the past freedivers used a more forceful approach to apnea (the art of holding your
breath). This technique was based on a form of hyperventilation in which the diver
forced the body beyond its limit with rapid inhalation and exhalation. The thought was
that this type of breathing was purging the body of harmful CO2 and therefore
increasing the level of O2 (oxygen). Unfortunately it is impossible to increase the level
of oxygen in your body by increasing your breathing. The only effect from
hyperventilation is a decrease in the level of CO2 going into the dive. The downfall of
this technique is within this lowered level of CO2 which postpones the mammalian dive
reflex. This has many negative results including a delay in reducing the heart rate,
continued steady consumption of oxygen, and a lag time in alerting the body and mind
of the need to breath. This dangerous combination leads to a false sense of well being at
depth until upon ascent where the water pressure
declines, CO2 levels spike and oxygen is sucked out
of the blood stream to refill the re-expanding lungs.
For this reason hyperventilation is the most
common cause of freediver deaths with
“Shallow Water Blackouts”.
Today technique's used by top freedivers are
centered around an idea of “relaxed apnea”. This
approach encompasses many components dealing
with relaxation, such as stress and anxiety, both
physical and psychological. To get the most out of
this technique we must eliminate all sources of stress
and anxiety and in the process use certain breathing
techniques to help reach a state of relaxation
necessary for a positive and enjoyable experience.
In order to completely relax and get the most out of
each dive we must understand and confront all forms
