Did you know that sonar
is harmful to marine life? Imagine getting hit by a wall of sound
waves almost twice as loud as the loudest rock concert in history.
Yet, had it not been
for the effects of sonar on fish, studies on sound therapy, focusing
on high intensity ultrasound, may not have kicked off. Sonar
technology evolved during World War II due to the threat of German
U-boats prowling the Atlantic, preventing merchant ships from
supporting the Allied war effort. Comprehensive medical research on
sound waves began around the mid-1940s.
Soon enough, treatments
like shockwave therapy were born. Normally, sound goes through the
ear and gets processed by the brain, prompting the body to take
proper action. However, shockwave therapy directly applies sound
waves to an injured part of the body, creating an entirely unique
effect: stimulating metabolism and blood circulation.
Metabolism simply means
the body's taking action to treat an injury or infection. After all,
natural healing processes, among others, require energy, which
metabolism can supply. Many studies also point to the sound waves'
ability to activate the body's natural healing mechanisms. How it
does this exactly is still a mystery.
To put it simply,
shockwave therapy "stimulates" the body into responding
quickly. This makes healing much faster than under normal conditions.
