Cold And Deep Water Diving – Things You Should Know Before Jumping In The Water

Our human body is getting used to being in environment temperature. And when this temperature is altered, it produces some health effects in the body that can be awful.

These effects can be avoided by knowing some advices before diving into cold water. Thankfully, technology and training have advanced throughout the evolution of diving to make submersion in hostile environments possible.

But despite that, we have to be conscious of the problems we can have if we do not have the required equipment.

The first thing we have to be sure about is using specifically designed equipment that has been properly maintained and successfully used.

Some people tend to use hoods and gloves, but some others are not used to them, so if you are one of them it’s better to begin dipping on the shore. In case there is free flow, it can be a problem if you do not have the basic equipage.

Why and What to Give A Thought About Diving?

Before you go underwater, you have to think about a planned diving which consists of what to do or what not to do when you are beneath the ocean’s surface.

It is not uncommon for surface air consumption rates to increase in cold water due to some level of anxiety. Therefore, it’s good to be aware of this when planning your dive.

One of the most important things is to learn how a free-flowing regulator works and at the same time, and how to be comfortable enough with air sharing.

Besides, you have to know which are the hypothermia signs and how to deal with them if they start to happen. When the body is in an inadequate environment, it reacts to it.

So you must be calm when you feel yourself starting to get too cold so that you can call the dive without getting desperate.

When the body is too cold, it automatically begins to occur some processes inside; the arteries get tighter, blood pressure and heart rate increase, and lungs wheeze for air.

After 5 minutes, hyperventilation can occur, while extremities, including arms and legs begin to lose feeling the ability to move and look cyanotic as well. As hypothermia sets in, the tongue swells and the body begins to give blood flow to vital organs like the brain.

Other things you have to know before jumping in the water:

  1. It is important to know what is under the surface and how deep the water is in order to reduce possible injuries. Sometimes people tend to jump in without knowing what is underwater provoking themselves fatal lesion until dead.
  2. A water landing is usually tough. Water does not absorb the hit when you fall from a great altitude. So the higher you jump, the danger is bigger.
  3. You gain speed as you fall, so jumping or falling from 40 feet means you could land in the water at 40mph.
  4. The safest way to jump into water is commonly called a pencil dive position which consists of jumping with your arms pressed against your chest. Keep your body as tight as possible and try to fall with your feet down.
  5. Before you jump into the water, take a deep breath and try to close your mouth as long as you can.

High divers enter the water differently than others because they are used to doing this kind of sport. They tend to straight up and down feet first, leaning forward, with their feet extended, hands together and arms with a pencil position to block their faces from the impact.

How Deep Can A Human Dive? 

Lack of oxygen is not the only prevailing factor when diving; there is pressure and also temperature to count. The deeper you go, the colder it becomes.

Pressure is also an important factor to consider how deep a human can dive. It is simply defined as the force per unit area. For every 33ft someone dives in water, the weight of the water above the person increases by 15 pounds/square inch.

This increase in pressure can cause lung failure; it is because the deeper you go, the more pressure is in the water, and this pressure can affect how your lungs contract and expand making breathing a rather difficult task under water.

The deeper you go, the more the pressure and the more your lungs begin to contract giving you a little supply of oxygen which was inhaled at the surface.

Since the pressure outside your body is far greater than the pressure inside your body, this will give your lungs so much work trying to keep you alive of which it might just fail and kill you at that very instant.

Most divers never go past 400ft, and the only way to really determine how deep a human can dive would be to run a live test which is very unethical of every profession and cruel of any human.

Even the divers that go as far as 200ft come back with side effects; negative side effects.

Humans can dive as deep as 100m when the lungs are air-filled, but with the aid of the equipment, can go a few meters deeper as much as 300m.

Scuba organizations have said, divers shouldn't go below about 130 feet, but a few years ago, one Egyptian diver went deeper, more than 1000 feet, establishing the new record Guinness.

Frequently Asked Questions

1. Why is it important to land feet first?

The primary reason for this is your own safety. Landing the feet first, you won't go that deep, and you won't risk to damage yourself.

2. Why do scientists warn against diving so deep?

When deep-sea divers take the plunge, they face a wide range of risks, including decompression sickness and equipment malfunction as well as drowning.

3. Why is it important to wear a diving suit?

Because these suits are capable of withstanding the pressure at great depth permitting the diver to keep a normal pressure.

4. What happens if a diver ascends too fast?

The most common thing is decompression sickness, or the bends, which means inert gas leaves the solution in your blood and tissues and forms bubbles. Later on, these very bubbles produce some effects that can cause lethal injury in the person.

5. How can these problems be avoided?

By using some supplies like breathing gas, closed diving bells, and saturation diving.

Conclusion

There are many things we have to know and many steps we have to follow if we want to spend a great time while diving without suffering any symptoms.

The most important thing is to have the required equipment and be aware of the problems we could have while jumping underwater. Besides, we have to be accompanied by expert people in case we need some help.
