How does scuba diving affect the body?

What are the side effects of scuba diving?

Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.

Is scuba bad for your health?

Can I be seriously hurt while scuba diving? Yes. The most dangerous medical problems are barotrauma to the lungs and decompression sickness, also called “the bends.” Barotrauma occurs when you are rising to the surface of the water (ascent) and gas inside the lungs expands, hurting surrounding body tissues.

What body systems are affected underwater?

Immersion of the human body in water has effects on the circulation, renal system and fluid balance, and breathing, which are caused by the external hydrostatic pressure of the water providing support against the internal hydrostatic pressure of the blood.

Can you fart while diving?

Farting is possible while scuba diving but not advisable because: … An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.

What is the most common injury in scuba diving?

The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.

What medical conditions can stop you from scuba diving?

Medical conditions such as asthma, diabetes and many cardiac conditions were long considered absolute contraindications to scuba diving.

Is scuba diving bad for your heart?

The physical work of diving contributes to the heart attack, as does the location where the cardiac event takes place. If you are on a beach or a dive boat when you have a heart attack, your chances of survival are lower than if you are in town around people.

Is scuba diving good or bad?

Although most recreational diving can be very relaxing while still involving increased activity and low levels of joint stress, which is beneficial to individual health, some forms of diving can be strenuous and could put an individual with predisposing conditions at potential risk of injury or incident.

Can your lungs collapse from diving?

If a diver experiences a pneumothorax while underwater at any considerable depth, it could be fatal. Collapsed lungs that occur for specific reasons, such as trauma or with medical procedures near the lung, are not disquali- fying but require a considerable time of healing before diving.

What happens if you don’t equalize when diving?

However, if a diver does not equalize early or often enough, the pressure differential can force the soft tissues together, closing the ends of the tubes. Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results.
