The first thing that these brave men and women will tell you is DO NOT PANIC! Way easier said than done of course but it's step one in the process of water survival! This is especially true when/if you are ever face down in the water with your hands zip-tided behind you! Keep calm and implement the following:

One of the methods Emerson recommends is the ‘sinking and bouncing approach’.
‘In shallow waters, use a sinking and bouncing approach to travel toward shore, ricocheting off the seabed or lake floor up to the surface for an inhale,’ he wrote.
‘When facing down, whether floating in place or using a backward kicking motion to swim to shore, the operative should arch his back in order to raise his head above water.

‘In rough seas, this may not give him enough clearance to get his head out of the water. Instead, a full body rotation will allow him to take a deep breath and then continue travelling forward.’

We wish and sincerely hope you will never find yourself in this position or in any position where you have to use this. However, it is comforting to know that there may be a way to save your life if such a thing should happen!

It is always a good idea to teach everyone you know how to swim and not just to swim but to survive in the water.
