Why is scuba diving so dangerous?
Like nitrogen, the body absorbs extra oxygen under increased underwater pressure as well. For most divers this is not a problem, but at extreme depths so much extra oxygen is absorbed that this life-giving gas becomes toxic. The effects include tunnel vision, nausea, twitching, loss of consciousness and seizures.
What are two problems that must be overcome in deep sea diving?
Diving poses two major challenges for air-breathing animals: hypoxia (a shortage of oxygen) and hyperbaria (high pressure at depth).
What are the most common problems that can occur on the surface when diving?
The most common medical problems are simple “squeezes.” These can affect your middle ear or face mask during descent. Squeezes cause pain in your ears. The pain is caused by the difference in pressure between the air spaces of your ears and mask, and higher water pressure as you go deeper in the water.
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.
Is scuba diving good or bad?
