Exotic marine life, coral reefs, rays of the sun breaking through the layers of water - the underwater world is fraught with many beauties. It is not surprising that every year more and more people go diving on vacation. However, scuba diving, in addition to a lot of pleasure, is fraught with a number of dangers.
The sea is an environment that is unnatural for humans. Therefore, you need to prepare for the dive with all seriousness, following the instructor's recommendations. Otherwise, an inexperienced scuba diver may face trouble.
The most common ailment is barotrauma, damage caused by changes in pressure during immersion or ascent. Internal organs are deformed, trying to adapt to new conditions. It is at this time that scuba divers are most often injured.
During an abrupt dive, the diver may experience discomfort, sharp pain or ringing in the ears. This is how the middle ear barotrauma manifests itself. If the unlucky swimmer continues to dive, it could result in a ruptured eardrum. In diving courses, experienced instructors teach beginners how to blow air correctly, which helps to avoid barotrauma.
If air is swallowed, barotrauma of the intestinal tract may occur. During the ascent, the air bubble expands, causing severe pain and vomiting. This usually happens during the ascent.
Barotrauma of the teeth is also not uncommon. Divers prone to caries, who have cavities in their teeth or poor-quality fillings, stack up with this. During the ascent, pressure is exerted on the dental nerve, which can cause severe pain.
However, the most dangerous is lung barotrauma. An inexperienced diver who does not exhale air upon ascent may experience severe chest pain. Barotrauma can lead to rupture of the lung or gas embolism - air bubbles entering the bloodstream, and this, in turn, can be fatal.
Newcomers to scuba diving can experience the so-called "deep intoxication" - euphoria caused by the action of nitrogen. This often pushes inexperienced divers into inappropriate behavior, which, in turn, can lead to irreparable consequences.
If your dive is successful, you surfaced and you feel good, take your time to relax. Remember that for another day after the dive, you cannot fly by plane, otherwise you risk getting the same barotrauma, but already at an altitude.
