"Cole believes that relaxation can't explain the changes in brain waves and blood chemistry in humans who've swum with dolphins.
Cole thinks these changes are caused by dolphins' sonar, which they use to scan the water around them. The sonar is incredibly precise; dolphins can "echolocate" a shark half a mile away in the ocean and determine whether its stomach is full or empty--and, consequently, whether it might be feeding.
"Dolphins produce an intense amount of echolocation energy," Cole says. "It resonates in your bones. You can feel it pass through you and travel up your spine."
Cole's theory is too complicated to do justice here, but it goes basically like this: A dolphin's sonar can cause a phenomenon called cavitation, a ripping apart of molecules. (You see it in everyday life when, for example, you throw the throttle of a speedboat all the way down, but the boat doesn't move; for that second, the propeller is cavitating the water.)
"It's very possible that dolphins are causing cavitation inside soft tissue in the body," Cole says. "And if they did that with cellular membranes, which are the boundaries between cells, they could completely change biomolecules." That could mean stimulating the production of T cells or the release of endorphins, hormones that prompt deep relaxation.
Someday, Cole says, scientists may be able to replicate dolphin sonar and use it in a precise, targeted way to bolster the immune system."
