Who said laughter is good for the soul?
"A cheerful heart is good medicine, but a crushed spirit dries
up the bones" (Proverbs 17:22, NIV).
Science has finally caught up with these words in the Bible that
King Solomon wrote some 3,000 years ago.
The following report is from The Week magazine: "Laughter
is good for your health-and now scientists know why. Researchers at
the University of Maryland found that when 20 healthy volunteers
smiled and guffawed while watching the comedy, Kingpin,
their blood flow increased by 22 percent, about the same increase
caused by aerobic exercise. But when volunteers watched
tension-filled scenes from Saving Private Ryan, their blood
flow decreased 35 percent.
"The researchers say that laughing apparently causes the
endothelium, the tissue that lines blood vessels, to expand, which
increases blood flow. Laughter may also improve arterial health by
reducing mental stress, which constricts vessels and cuts blood
flow. A healthy lifestyle-researcher Michael Miller tells New
Scientist-would include 30 minutes of exercise three times a
week, and 15 minutes of hearty laughter each day."
