The Ice Bucket Challenge has raised an impressive $80 million for the awareness and research for the disease called ALS or Amyotrophic Lateral Sclerosis. However, there's a recent report that says this challenge is dangerous and could even be considered deadly.

One of the most common tragedies that could be associated with cold water is hypothermia. Mike Tipton, professor and physiologist at the University of Portsmouth, said, "There was a bit of a preoccupation with hypothermia dating right back to the Titanic, and then reinforced during the Second World War."

However, fatal hypothermia only happens when one is exposed to a cold water for a long time.

When someone does the Ice Bucket challenge, they will be immersed in cold water and their bodies would experience a drop in skin temperature. Then, they will be triggered by a reflex called, "cold shock response."

"It's basically exactly the same as you would imagine if you stepped or jumped into a pool they said was heated and it wasn't, or stepped under a shower that had just run cold," Tipton explains, "It's a gasp response followed by uncontrollable hyperventilation."

Gasping for air can completely deter one's ability to hold their breath. Even if it is possible to hold one's breath for about a minute, this is a different case when taking into account cold water.

When one loses the ability to hold their breath, it could technically be considered drowning.

As it stands, there have been two deaths caused by the Ice Bucket Challenge. One was an 18-year-old from Cameron Lancaster who drowned after jumping into a quarry. The other was 40-year-old Willis Tepania from New Zealand, who drank a bottle of bourbon after taking the ice bucket challenge the night before.

Also, Corey Griffin, 27, who raised $100,000 for his friend Pete Frates who suffers from ALS, died after diving in the Nantucket Island Harbor.

When the cold shock and diving responses of the body coincide, they can become lethal.

"If you've got those two responses co-activated then you've got a response trying to accelerate the heart - the cold shock response - at the same time as you've got a response trying to slow it down, the diving response," said Tipton.

He advised participants to "avoid total immersion."

"If you go into cold water then the physiological responses will be much more profound and prolonged than if you just have a bucket of water thrown over the top of your head," he stated.
