Diving immerses individuals in the wonder of the underwater world, but with diving comes risk, with possibilities of ear barotrauma, lung overexpansion, and decompression sickness. Regardless of the level of diving experience (beginner or lifelong diver), acknowledging risk and how to prevent and manage diving injuries is critical. From equalizing pressure correctly to recognizing early signs of nitrogen narcosis, prevention requires thought and action from a diver to avoid serious accidents (injuries) that require medical attention. This article will cover a few common diving injuries, including causes and prevention strategies, so you can dive safely.
Knowing how to manage an incident such as lung overexpansion with a rapid ascent or decompression sickness with negligence of a safety stop will help ensure you continue to enjoy exciting dives with knowledge and confidence. The following expert-based information will ultimately provide guidance and the ability to manage and mitigate diving injuries, whether you enjoy diving in reef systems or deep diving. Dive in to learn how to dive responsibly and injury-free while you enjoy the ocean's mysteries!
Ear barotrauma is among the most common injuries that divers encounter. Barotrauma occurs when pressure changes damage the eardrum or middle ear during descent or ascent. Symptoms can include pain, muffled hearing, and sometimes dizziness. The key to preventing barotrauma is equalization: performing the equalization techniques, such as the Valsalva maneuver, early and frequently. Never force an equalization technique if doing so causes pain, and do not dive with a head cold or congestion. If you experience discomfort during a dive, ascend slightly to relieve some pressure. Severe cases of ear injuries may require medical attention to prevent permanent damage to your eardrum. Always be gentle with your equalization techniques and descend slowly to protect your ears while enjoying pain-free dives! Remember to stay safe and dive smart!

Lung overexpansion injuries are some of the most serious diving-related emergencies. They happen when trapped air bubbles expand as one ascends, damaging the lung tissue. This may result in severe conditions that can be life-threatening, such as arterial gas embolism (AGE) or pneumothorax (or collapsed lung). These injuries are preventable. The leading cause is holding your breath during ascent, even for a few seconds. Scuba divers must breathe continuously and ascend slowly to expel the air from their lungs. Understanding how lung overexpansion works and how to avoid it is incredibly important for safe diving. This section will identify the causes, symptoms, and safety tips that every diver needs to engage in this silent but deadly underwater hazard.

Decompression sickness (DCS), also known as "the bends," refers to the formation of bubbles in the tissues due to dissolved nitrogen caused by rapid ascent or inadequate decompression. Although most commonly associated with scuba diving, DCS can occur in any activity where you ascend rapidly against a pressure change. Signs and symptoms of DCS can vary from joint pain and rash to potentially life-threatening neurological changes. Risk factors for DCS include depth and length of submersion, failure to follow a safety stop, and dehydration. If you recognize any signs of DCS—such as excessive fatigue or dizziness—take a moment to assess your condition, seeking emergency care if necessary. DCS can be life-threatening, particularly when in a stopped state when the diver is away from a boat: delayed intervention can be dangerous. Understanding the depth pressure changes helps divers weigh their choices and assess risk while underwater.

Nitrogen narcosis, "the Martini effect," is a serious medical condition that can impair the diver's judgment and motor skills at depths greater than 100 feet below the surface. Nitrogen narcosis is caused by the pressure of nitrogen in the diver's bloodstream, which manifests similar effects as alcohol intoxication, including slurred speech, slowed reflexes, and impaired judgment. All divers can be affected, and symptoms tend to increase the deeper a diver goes. It is essential to recognize the early signs of nitrogen narcosis, including euphoria or confusion, to avoid making potentially fatal judgments. The best prevention methods are to limit the depth of the dive, ascend to a shallower depth if the diver becomes impaired, and use a helium-based gas mix for diving below 100ft. When diving at depth, understanding nitrogen narcosis is essential to do so safely, but generally, if you stay alert, respect the limit of your depth, and ultimately prioritize safety, you should have no problem.

Learning to prevent and manage diving injuries will help you enjoy safer and more enjoyable experiences on and under the water. If you follow established best practices—like equalizing correctly to reduce the chance of ear barotrauma, ascending slowly so as not to overexpand your lungs, and following dive tables so as not to get bent—you significantly lower your risks. If you've been warned about signs like dizziness associated with nitrogen narcosis, being able to recognize them early enough allows you to take action quickly. Proper first aid and procedures, such as administering oxygen, are essential for safety and can save lives.
You should always dive within your comfort limits, properly hydrate, and eliminate getting ready for the dive! Being prepared and knowing about risk is your best defense against dive injuries. If you are a recreational diver or an aspiring tech diver, practicing safety means more diving trips and adventures and fewer emergencies. So gear up, stay alert, and dive responsibly. The underwater world and oceanic beauty can be enjoyed with a fuller adventure if you can return to the surface unscathed. Keep diving, but ensure the safety precautions are your essence!
