How Deep Can A Human Dive | Ultimate Geeky Guide!

How Deep Can A Human DiveThe wondrous aquatic world, the feel of weightlessness and the realization of how precious life is takes the divers back to the ocean again and again.

Nonetheless, whoever has the slightest idea about diving knows how dangerous it can be.

So, it’s important to know how deep can a human dive.

And that’s exactly what we’re gonna cover in this article and a lot more.

Let’s get started.

Different Types Of Diving

There are various types of diving and they are termed as per to their purpose or the equipment used. Some of the most widely popular ones are mentioned below.

Snorkeling

Snorkeling is when you dive through a water body wearing a mask with a breathing tube attached to it. The length of the tube puts a limit to the depth which a diver can cover. Snorkeling is widely popular in tropical areas where the water is warm. Underwater sports, for instance, underwater hockey or underwater rugby, also use such devices to breathe.

Before you decide to breathe underwater with a snorkel mask, make sure your equipment are alright.

Deep Diving

There is deep-diving which is when a diver dives below 18m from the surface of the water. There is a limit up to which a diver is usually allowed to go underwater (40m). But this varies from countries to countries and there are records of humans diving as deep as the ocean goes. You will need special equipment to make such a dive which saves you from hypothermia and the intense water pressure and of course supplies you with oxygen.

Scuba Diving

Scuba diving is referred to as the dives where divers carry their oxygen tanks with them to swim underwater. The acronym of the word “scuba” is self-contained underwater breathing apparatus.

Because the diver has their breathing air with them, it allows them to dive for a longer period compared to free-divers who use no gears at all and into the deepest corners of the ocean. A diver has to wear a special suit and also carry various equipment, other than the compressed air, with them while making such a dive.

It would be unwise to think you get to scuba dive anytime anywhere just because you have the appropriate gears with you.

For scuba diving, you will need scuba dive certification which usually comes after a rigorous training schedule. Scuba diving can be done for various reasons like it can be entirely recreational or the purposes can be scientific, safety or military.

Wreck Diving

Wreck divers examine human history left at the bottom of the ocean.

Ice Diving

It is when you cut a tunnel through the ice underwater to get to the other side.

Cave Diving

It is exploring the underwater caves and can often be a rescue mission.

How Deep Can A Human Dive With Gear

For beginners who just want to explore the shallow waters around the beach, snorkeling sounds like the best idea. You can easily get a snorkeling mask by the beach or from your hotel and dive right in.

However, it’s quite complicated for advanced divers. First off, you will need all the right gears with you and have the basic knowledge to be able to tackle situations that may arise underwater, and for that, you need at least a week’s worth of training.

Currently, the record of the deepest dive yet is held by Egpyt’s Ahmed Gabr who dived 332m into the ocean near Dahab in 2014. Making such a dive takes years of practice, experience and most importantly will power as many things can go wrong as you plunge deep into the unknown.

One such problem that divers face is nitrogen narcosis which is a reformed state of mind as the diver dives 30m below the surface of the water, due to breathing compressed air underwater where the pressure is too high for human bodies to function properly.

This could disrupt the divers’ concentration and hence result in wrong decision making. To fight off the intoxication, divers mix a special gas called the Trimix with the air they carry. The high water pressure can also cause HPNS (high-pressure nervous syndrome) which can make the diver dizzy, tired and cause the muscles to ache or twitch.

Another major problem deep-divers face is oxygen toxicity due to breathing high levels of oxygen in a short time. As you go into the depths, the air consumption, with that oxygen consumption, increases.

Divers can drown due to oxygen toxicity as it can cause heart failure or seizure. This is why deep divers mustn’t dive to the depths too quickly. They must keep on increasing the depth slowly so that their body gets used to the surroundings and try to keep their heart rate as normal as possible.

How Deep Can A Human Dive Without Gear

Amongst the diving fanatics, some people take this thrill to the next level and go for a deep dive without any gear. People become astonished when they find out how deep a human travelled in a single breath but the unbelievable has happened. The world record for the deepest free-dive is held by Herbert Nitsch who dove 253m into the water in 2012.

Some people are believed to have an active ancient diving reflex called a mammalian diving reflex which enables the human body to biologically shift the blood around the body and control breathing to make such free dives possible. There is no specific limit up to which a person can free dive but the pressure exerted on the lungs underwater makes it impossible to continue after a certain depth (305m).

Conclusion

For all the divers, both in practice and even in heart like myself, there is everything you needed to know about how deep can a human dive. For beginners, a piece of advice would be not to take big risks like zealots. Take the necessary precautions and training because the ocean and the beautiful aquatic world beneath are not going anywhere and are all yours to explore.
