There have been a number of fortunate elements on this case which helped the survivor, Kay Longstaff.
Sea survival teacher Simon Jinks says she might have sunk three or 4 metres beneath the water’s floor after the preliminary fall and was lucky to not be pulled underneath the ship.
There could be turbulence within the water subsequent to a cruise liner and “some waves can push you away and some waves can take you in”, he mentioned – nevertheless it depends upon the velocity of the ship in addition to luck.

Her second stroke of the luck was the heat of the water she fell into – estimated to have been about 28-29C, or “a little bit warmer than a swimming pool”, says Professor Mike Tipton, an skilled on surviving excessive environments.
An individual can survive for round one hour in 5C water, two hours in 10C and 6 hours in 15C – but when the temperature is within the excessive 20s then it’s attainable to outlive for round 25 hours, he says.
People can go into chilly water shock if the temperature is simply too low, which implies they lose the power to manage their respiratory and may doubtlessly inhale water or drown.
And as their physique temperature falls, somebody can develop into drained, confused or disorientated.
If she’d fallen into the ocean round Britain, she’d have been in water of between 12C and 15C – cool sufficient to trigger chilly water shock.

With the time it is attainable to outlive within the water restricted, it is essential to get rescued as quickly as attainable.
On this case, individuals on board seem to have seen the girl was lacking and used the ship’s CCTV to pinpoint the time of her fall and therefore her possible location.
However, as Prof Tipton says, it is nonetheless very laborious to search out somebody floating alone at sea – significantly at night time. “It’s just a really difficult thing to find what essentially is a head in the water.”
Ladies’s excessive proportion of physique fats – usually 10% greater than males – can work of their favour.
“They have more subcutaneous fat and that means they are more buoyant because the body’s buoyancy comes primarily from the air and fat in the body,” Prof Tipton instructed BBC 5 Stay.
The additional fats additionally helps hold the physique heat, which helps when the human physique will get drained within the water.

“I think there is a big psychological aspect,” mentioned Professor Tipton. “At the time, hours six, seven, eight and nine it must be a fairly desperate situation to be in.”
On this case, the girl reportedly instructed a rescuer that she sang in a single day to cease her getting chilly.
Mr Jinks, whose firm, Sea Regs, trains boat skippers and crews, says an individual’s “will to survive” is essential. “If you go into a situation and think, ‘I’m going to die,’ your psychology changes,” he mentioned.

What in regards to the impact of alcohol?
The RNLI says round one in eight coastal deaths within the UK entails alcohol and urges swimmers to keep away from going into the water after a drink.
It warns that alcohol can critically impair judgement, reactions and talent to swim.
However Prof Tipton mentioned in considered one of his current research, volunteers consumed six vodka drinks earlier than going into the water.
And he mentioned alcohol “made absolutely no difference to their physiological responses to immersion”.
“What it does do is it makes your decision making a little more difficult. People make bad decisions when they’ve got alcohol on board.”
