How do Snorkels Work Underwater | A Unique Guide for All Beginners

This article is majorly concerned about educating and sensitizing us on how to do snorkel, how do snorkels work underwater, and more so, how long can we sustain breathing underwater with a snorkel and lots more.

Snorkeling is a beautiful and relaxing way to observe the oceans’ colorful and fascinating world, just below the water’s surface. Snorkelers use transparent plastic masks and a short tube to breathe while floating face down on the surface of the water.

You can observe corals and marine life without frightening the fish with your movements and without having to emerge and gasp for air every minute. Just drifting and being consumed by the underwater world is enough to escape the problems of everyday life.

Tips for Proper Snorkeling

Buy a snorkel and mask that is comfortable for you. Try this on and adjust the straps to fit. If you can, try it on in the water to make sure it won’t leak.

  • If you have trouble seeing, you can have a mask made to match your prescription so that you can see underwater without glasses.
  • Put the mask on and pull the straps until it is snug around your eyes and nose. The breathing tube should be close to your mouth, but don’t put it in your mouth yet.
  • Lie flat on your stomach in the water. Hold your face in the water at about a 45-degree angle.
  • Lightly bite the mouthpiece of the snorkel. Close your lips around the snorkel, and hold the snorkel in place.
  • Breathe slowly and regularly through the tube. Breathe slowly, deeply, and carefully with your mouth through the breathing tube. Don’t panic: you can always raise your head above water if you want. Just relax and become aware of your breathing. The sound of your breaths should be quite audible through the snorkel. When you get into the rhythm, relax, and enjoy the underwater world.
  • Avoid hyperventilation. Slow, steady breathing is essential when snorkelling. If you hyperventilate with a snorkel, you can pass out in the water – a hazardous prospect.
  • Drink enough because you might lose a lot of water in the ocean. If you plan to snorkel for several hours, take breaks to drink. Whatever you do, don’t drink the saltwater.

Being in the sea is never completely safe. It is possible to encounter sharks, stinging jellyfish, and other dangerous marine animals, even in high-tourist snorkeling spots. Even currents can propel you out into the open water and high waves that can hit you against sharp rocks. You must be able to trust your swimming skills and should never snorkel alone.

Pay attention to your surroundings. Following a few sparkling fish can quickly get you further out into the ocean that you want. Avoid dangerous situations by being sensible about how far out you swim.

How to Substain Breathing Under Water with a Snorkel

In diving, we often tend, wrongly, considering that the best diver comes out with the most air in his tank. This is what we say to ourselves at the beginning when we want to learn scuba diving. So yes, having low air consumption while scuba diving is essential. But, sorry for the small lungs, while low air consumption is an important quality, it is not the diver’s most outstanding quality.

Beyond optimizing the number of the bar used in scuba diving, it is essential to use your breath well to avoid some of the dangers of scuba diving, such as decompression.

How do Snorkels Work Underwater

Why do you want to lower your air consumption while scuba diving?

However, optimizing your air consumption while scuba diving has many advantages:

First of all, this allows you to spend more time underwater in logical diving without going beyond the non-decompression stage.

Also, it gives you a safety margin so as not to end the dive on your last 10 bars.

Finally, when you dive into a group, you cannot force your group to go up because you reach 50 bars while everyone is still at 100 bars.

Guide on How to Useless Air while Diving

Keeping you inform

So, let it be clear; it is not by diving five times a year that you will have a dream body. Diving keeps all the muscles in shape and works, but you won’t lose those extra pounds unless you do reverse drift diving regularly.

However, although weightlifting is unnecessary to dive, this sport still requires being in good shape, if only to put on your wetsuit and get in the water. In the right conditions and do not start the dive out of breath. Also, many dives around the world are drifting and sometimes require serious fins. Although it is not necessary to be a swimming champion to dive, you also need to learn how to swim to dive.

Concretely, to consume less air in scuba diving, it is necessary not to breathe too much and to be able to maintain a low level of effort.

Buy the right diving equipment

Very often, in terms of size, men tend to think that they are likely to get bogged down or, conversely, to build up muscles and suddenly, to buy a wetsuit that is much too big for them. Conversely, women are looking to buy a wetsuit that highlights them and likes to be tight in their wetsuit. There is no sexism at all in this remark, just experience. The problem is that a suit or a BCD that is too large or too small will cause more effort or, conversely, breathing difficulties. Also, you need the best diving equipment.

Wear the right equipment

Before diving on Richelieu Rock in Thailand or on the Tiputa pass in Polynesia, you must know that you do not take the super practical and pretty little fins. Take your big black toad fins underwater; you will tire yourself out, it’s obvious. Also, think carefully about the water temperature. It seems obvious again, but thermal protection plays a vital role in air consumption. Have it in mind that underwater heat loss takes about 20 times faster than in air, and the cold is not your friend when diving. To warm-up, the body will burn a lot of fat and sugar, and while the idea of ​​losing some weight might sound fantastic, it inevitably results in more air consumption. Therefore, a suitable combination will not be cold and will not increase air consumption.

How deep can you snorkel

Do not overquire yourself

Also, many divers wear equipment by thinking that it is good at having than not having it. At times, we do not use our equipment, which can even be counterproductive and strongly impact your air consumption. Take only what you need.

Think about your diving lessons

Be streamlined, aerodynamic. Don’t forget to bring in your hoses and your second regulator. It’s simple physics. Imagine the difference in air friction on a big bulky truck and a streamlined sports car. In water, it is the same. Learn how do snorkels work underwater. 

Improve your buoyancy and technique

The best way to optimize your air consumption while diving is to improve your buoyancy. For those with a bit of memory, ludion is an exercise in the Open Water Course, which teaches you to achieve neutral buoyancy. Buoyancy is fundamental to controlling your air consumption in scuba diving because you must either fill or empty your BC or fin when you go up or down. In either case, you are consuming a lot of air. This question also joins that of ballasting in scuba diving explained above.

Beyond air consumption, the fact of not controlling its stability can lead to risks in scuba diving. So take the time to practice mastering your buoyancy. Besides, a little advice, if you need to inflate your BC a little and you feel comfortable underwater, use the knowledge acquired from your level 1 scuba diving and fill your BC with your mouth. Will save air.

Do not apnea

Also, be careful not to free dive. Even create stress in scuba diving, which can be hazardous. In fact, in apnea, your blood cells do not receive the renewed air they need, and your body will produce toxic carbon dioxide. It will create an imbalance; hence your brain might generate a stressful situation, resulting in shortness of breath and an increase in the consumption of air underwater.

Scuba diving definition


Breathe in slowly and deeply. Remember, diving is an anti-stress remedy like a yoga class or a good walk in the park. Do not move, move little, let yourself slide. 

We talk to you a lot about the dangers of diving because there are some, but it is, above all, a pleasure, and there are very few accidents in recreational diving. So relax while diving. Breathe deeply, preferably with your lower lungs, like in yoga, and observe your surroundings. Stop thinking about your breathing; just let the air come out of your body usually.

Stress is the leading cause of increased heart rate. Focus also tends to increase physical activity and can cause cramps, among other things. It is also crucial for the novice diver to know how to manage a twitch in scuba diving. Often, stress is created by the diver himself, especially when he is learning to scuba dive. It’s quite familiar; moreover, breathing underwater is not the most natural. But don’t worry, millions of divers have been there, and then you are not alone, and your guide is there to take care of you.

Prepare your dive

Stress comes from anxiety. The more preparations are made, the less anxious you will become, and the less air you will consume while driving. 

Basic Diving Safety Rules

The right reflexes you need before going to dive.

It is crucial to eat well.

Diving doesn’t seem like it at first glance. Still, it’s a sport that requires a lot of energy from carrying equipment that weighs several kilos out of the water. Fighting against the effect of nitrogen saturation, warming up in water (even when it feels hot, our body burns some calories which keep us warm) without counting the kicking as long as there is a little current. Be careful not to go in on an empty stomach: choose slow sugars and avoid too fatty foods as much as possible.

Good hydration before exercise

Likewise, you become very dehydrated while diving. “Diving changes the physiological activity of our body. In water, blood is concentrated around vital organs. To lower the pressure, the body gives off all the water in the blood. Hence this irrepressible urge to pee after each dive!

 And to continue his demonstration: “Also, there is the fact that the air in the bottle is dehydrated so it must be humidified to promote gas exchange. “In short: drink lots of water, tea, fruit juice… Everything, except alcohol, of course.

Knowing how to trust yourself in sport

This rule applies to all sports and outdoor activities, but sometimes it’s essential to repeat the basics: trust yourself. If it’s too sea-going, or you’re feeling woozy, or just merely uncomfortable, don’t force yourself. 

“It is necessary to know your limits and not to go beyond them. While diving, a panic attack underwater or shortness of breath can be dangerous. You are no longer focused on the basic rules, and you can do stupid things,” says Julien Knee.

If your level tells you not to exceed 20 meters, there is a reason. When you’ve never dived deep, you don’t know how your body will react, especially when faced with the intoxication of the depths.

Never dive alone

“When diving, you’re never alone underwater,” says Julien Knee. It is a sport that is done in pairs.

We watch each other, and then, it’s still fun to discover the seabed together and to be able to talk about the fish that we met while getting back on the boat! “.

The rule is simple: never stray more than two meters from your partner to react quickly in the event of a problem. If your buddy is fainting, has a problem with their regulator, or needs some air soon, you should be able to be there in three fin strokes.

How do you choose your ideal partner? “There is no precise rule, assures the specialist. In general, we will combine people who have the same level, experience, and air consumption. Still, on a very technical dive, we can also put together someone very experienced with a diver who is less so. He can help him with any problem. “

Control your ascent to the surface

This is the basic rule: when diving, it is essential in ascending slowly to give the body time to eliminate the nitrogen; otherwise, there is a risk of a decompression accident.

It is estimated that an ideal ascent does not exceed 10 to 15 meters per minute. If you have a dive computer, you won’t have to worry about this as it is set to sound if you think you’re a rocket.

Understand the safety level

To be sure to eliminate as much nitrogen as possible in the body, the vast majority of divers do a “safety stop.” The principle is simple:

If you are in a coral garden, you will not see the passage of time; otherwise, be patient.                                    

It can be zapped when conditions are difficult, especially if there is current. But when you can do it, it is an additional assurance of not having a decompression sickness”.

Respect the gap between two dives

Diving several times a day is possible, but you respect a “surface interval” on condition. In general, it is considered that it is necessary to stay at least two or three hours on the surface before diving again. Likewise, if you plan to explore the seabed multiple times during the day, plan to take the deepest dive first.

Do not dive before taking the plane

You may have been particularly careful during your ascent and followed the safety stops to the letter; your body did not have time to eliminate all the nitrogen it contains. Do not panic; it continues its work on the surface, and all these little “bubbles” will disappear without damage as long as you do not take the plane immediately after your dive.

 Pressurizing the cabins could indeed lead to a decompression accident. For a simple dive, it takes an average of 12 hours before flying and 24 hours if you have dived several times.

No violent sport after Diving

Also, it is recommended not to do apnea or sport after a dive because of the tissues’ nitrogen saturation. 

A violent effort indeed promotes decompression sickness. It would still be a shame to injure yourself after Diving.

If you don’t feel well going back up, say so

The dive went well, and yet: since you came back up, you feel woozy. Muscle pain, itching, and severe fatigue, nausea more so, if there is a good chance that it will not be serious, do not stay with your discomfort: these signs can be the symptoms of decompression sickness.

Take advice from your driving instructor, who will be able to make an initial diagnosis and lead you to a hyperbaric doctor if in doubt. The earlier a decompression sickness is spotted, the better it will be treated.

Most snorkelers prefer a leisurely swim on the surface of the water. From there, the fantastic underwater world can be explored, and the unique fauna discovered. Diving may make up 10% of water sports, but that’s one of them.

While using a snorkel mask, you can dive to a depth of 1 to 2 meters. Wearers of a snorkel mask can also not equalize the pressure (e.g., holding their nose closed while exhaling).

How a person can dive with a snorkel largely depends on the ability to hold their breath and the person’s fitness. 

Breathing with a snorkel mask

Snorkel masks are also known as full face masks. They combine a snorkel and diving mask in one item and allow natural breathing through the nose and mouth.

Snorkel masks do not have a mouthpiece so that you can breathe in them like overwater.

The masks offer significantly more space and are usually comfortable. Snorkel masks are, therefore, more suitable for beginners, children, and people with claustrophobia. Even snorkel masks go along the tube, which lay on the mask’s upper side and supplies the mask’s wearer with fresh air.

The common problems of simple snorkels do not exist with snorkel masks. Instead of a mouthpiece that sticks in your mouth while snorkeling, which results in fatigue of the jaw muscles, you can take a grinning selfie with a snorkel mask. The snorkel mask’s fogging is much less common, and an action cam can be attached to the cover.

Did water enter the snorkel while diving?

A certain amount of water goes through into the snorkel and thus flowed directly into the mouth was completely average in the past.

Nowadays, one sees more and more dry snorkels equipped with a splash guard and a float valve on top of the snorkel to block water from entering. Any water that has entered is flushed out via a blow-out valve. Classic snorkelling is only partially dry snorkel and, therefore, suitable for Diving. In contrast, almost all snorkel masks have this type of technology.

We believe this you have learned mostly on how to do snorkels work underwater and other relevant details discussed in the article. 

The field of view of a snorkel mask is significantly more comprehensive, and you can smile with a snorkel mask for underwater selfies. However, snorkel masks are not well suited for real dives. On the one hand, the masks are only suitable for a maximum diving depth of one to two meters. And on the other hand, the snorkel mask’s air is only sufficient for a few breaths. Long dives are, therefore, not possible.

These masks are best suited for snorkeling trips on the surface of the water. Those who would like to dive a few meters deep would prefer the classic equipment with diving goggles and a snorkel.
