12 Interesting Scuba Diving Facts for Kids 2024!
Scuba diving is a popular form of diving! Scuba divers uses a breathing apparatus that helps them breathe properly underwater. In this article, we’re going to take a look at some fun and interesting facts about scuba diving, so let’s get right into it.
12 Interesting Scuba Diving Facts
1. The word “scuba” was actually an acronym.
Did you know that the word “scuba” wasn’t always a word on its own. SCUBA stands for Self-Contained Underwater Breathing Apparatus! This term was coined by Christian J. Lambertsen, who was a physician in the United States Army Medical Corps. However, it’s interesting to note that although “scuba” used to be an acronym, it is now a singular word that refers to the form of diving that uses a breathing apparatus.
2. Scuba diving cannot be done without the necessary breathing equipment.
If you didn’t know this already, it might interest you to know that you cannot go scuba diving without a breathing apparatus. This is because if you went diving without the breathing apparatus and only a regular oxygen tank and breathing tube, you wouldn’t be able to physically breathe at all underwater. Scuba diving equipment is extremely complicated, and it allows divers to breathe normally while they swim. It isn’t enough to go scuba diving with only an oxygen tank.
3. Scuba diving is a professional job.
Though many people enjoy scuba diving for fun, it is also an actual job! Many people scuba dive professionally; they work as scuba diving instructors and guides. Additionally, there is an area of scuba diving called military diving, where people belonging to the armed forces are trained to carry out missions underwater. These missions include searching for and rescuing trapped people, salvaging, infiltration, and underwater combat, to name a few.
4. The longest scuba dive in history lasted for over 145 hours.
An Egyptian man named Saddam Killany has set the world record for the longest open water scuba dive. Killany’s dive lasted for over 145 days, or six days, and narrowly beat the previous world record of 142 hours. It took several years of training and practice, and when he finally went underwater, Killany slept, exercised, and prayed. He had a full-face mask, which allowed him to sleep.
5. Jacques Cousteau invented the first type of scuba diving equipment.
Cousteau’s invention was called the Aqua-Lung. It was the first piece of diving equipment that became popular all over the world and was commercially successful. Today, the Aqua-Lung is more commonly known as a demand valve or diving regulator. Since Cousteau was an oceanographer and filmmaker, he needed a special piece of equipment that allowed him to remain under the water for long periods of time. With his background in the navy, Cousteau worked together with Émile Gagnan and came up with the Aqua-Lung.
6. You can burn hundreds of calories an hour when scuba diving.
Although swimming is a great way to burn calories, scuba diving might just be an even better way to work out! Research shows that scuba diving can burn anywhere from 400-700 calories an hour. The reason for this is that your body is working harder than normal because of the physical conditions. In addition to swimming and working against the current, you are also breathing at a different depth than normal, regulating your breathing and maintaining buoyancy under the water.
7. Scuba divers don’t only breathe oxygen.
Did you know that scuba divers don’t breathe pure oxygen when they’re under the water? If a scuba diver were to breathe pure oxygen under the water, they would die. This is because breathing pure oxygen at such a depth would be poisonous. Therefore, the gas in the breathing tank is a mixture of oxygen and nitrogen.
8. The color of the water changes the deeper a scuba diver goes.
Although water is clear and has no given color, water molecules absorb various colors of light and absorb the molecules of light that have a longer wavelength first. This color is usually red, but when red is removed, the water appears blue. However, the further down into the ocean a diver swims, the more light is absorbed, and the less color is visible.
9. Scuba diving is extremely risky.
It’s no secret that scuba diving takes a physical toll on the human body. Although it is fairly safe to do, there can be several risks involved if it is not done properly, mainly because the human body is not built to withstand the water pressure of the open sea. Divers can experience decompression sickness, oxygen toxicity, air embolisms, and dehydration. They can also drown if their gas masks fail.
10. You must never hold your breath when scuba diving.
This is scuba diving’s golden rule! If you hold your breath while you’re scuba diving, your lungs will burst, and you will die underwater. As you’ve learned by now, the pressure of the water when scuba diving is extremely high, and as a result, your body reacts differently to the process of breathing. This means that the air pressure in your lungs is different than how it is on land! Therefore, if you hold your breath while scuba diving, the walls of your lungs could tear or rupture, and air bubbles will travel into your chest and bloodstream, and you will die.
11. It is important to ascend back to the ocean’s surface slowly.
The most important aspect of returning to land safely after scuba diving is ascending slowly. If you ascend too quickly, you are not allowing the nitrogen in your bloodstream to dissolve completely. If you ascend very quickly and without pausing in between your ascent, bubbles of nitrogen could form in your bloodstream, and you could get sick from decompression.
12. The Great Blue Hole is one of the most famous and popular places to go scuba diving.
The Great Blue Hole is located in Belize and popularized by Jacques Cousteau, who is considered to be the father of scuba diving. It is a marine sinkhole that is over 70,000 square meters wide and 124 meters deep. The reason this spot is so popular among tourists is because of its clear water and varied aquatic life! The Great Blue Hole is home to Caribbean reef sharks and midnight parrotfish, as well as various other rare species of fish.
In this article, we walked you through a list of fun facts about scuba diving. Although scuba diving can be scary and sometimes dangerous, it is also a lot of fun to do! It allows you the chance to experience aquatic life in various forms, and is an alternate way of testing the human body’s limits. We hope you learned something new today!
