Dec. 11, 2000 — You don’t ought to be the small mermaid to enjoy life beneath the sea. But, for people who enjoy scuba diving, there has long been a concern that rehashed jumps over many years may have harmful impacts on the central apprehensive system. Fortunately, a new consider published in the diary Neurology recommends that scuba divers have no more noteworthy hazard of long-term brain problems than nondivers.
In the think about of 24 proficient divers and 24 nondivers, the divers did not appear more signs of brain anomalies on magnetic reverberation imaging checks than the carefully chosen bunch of nondivers. The proficient jumpers, military jumpers from the German Naval force, were an average of 38 years ancient and had an normal of almost 1,407 hours beneath water.
An estimated 2.5-3.5 million Americans take part in recreational scuba jumping. Another half a million become certified each year within the U.S.
“Our study does appear that jumping … appears to be safe when performed concurring to diving rules,” lead analyst Günther Deuschl, MD, a neurologist at Christian-Albrechts-Universität of Kiel in Kiel, Germany, tells WebMD.
Past ponders appearing higher rates of neurologic abnormities were drained jumpers with a history of decompression affliction — too known as “the twists.” Caused by the generation of nitrogen bubbles taking off the tissues as well rapidly on ascent, the bends may be stamped by numbness, shivering, joint torment, abdominal torment, heaving, dizziness, migraine, and possibly paralysis or death.
None of the divers within the new think about had ever experienced the twists.
“The imperative things are to breathe regularly and never hold your breath — particularly when coming up, since the discuss in your lungs will expand,” says Ted Maney, a jumping security officer at Northeastern College in Boston, and the prompt past-president of the American Academy of Underwater Sciences, based in Nahant, Mass.
“There are a parcel of conditions that might confine you from jumping,” he says. “Any heart or lung issues need to be assessed with tests to degree lung function and chest X-ray.”
Scuba jumping has numerous benefits, says Maney, who has been diving since 1977. “For me, as a scientist, I get to work in a environment that I something else wouldn’t have get to to. Diving permits us to investigate and actually work and do research in water.”
“It’s very safe in the event that you don’t have any preexisting conditions,” he says. Maney’s counsel to future jumpers? “Take a course and take after rules, and you shouldn’t have any issues,” he tells WebMD.
“In the event that you are suitably prepared and don’t fair go out and use tanks without preparing, scuba diving can be safe and a fun wear,” concurs Lewis Maharam, MD, a sports medicine specialist in New York and the president of Unused York chapter of the American College of Sports Medication.
Maharam, whose epithet is “scuba-Lou,” has been diving for 35 years. “It’s secure as long as you know what you are doing,” he says.
“Recreational don plunging is an amazingly secure endeavor,” says Michael Marks, a part and ace scuba coach of the Professional Affiliation of Jumping Teaches and a jumping educators at Yeshiva College in Modern York.
“The wear is made even more secure with computers that screen time and nitrogen assimilation,” says Marks, who has been jumping for about 30 years.
