A
When did
you last see a polar bear
？
On
a trip to a zoo
，
perhaps
？
If you had attended a winter
activity
in
New
York
a
few
years
ago
，
you
would
have
seen
a
whole
polar
bear
club
．
These
water
．
Th
at day
，
the air temperature
was 3
℃，
and the water
temperature was a little
higher
．
The
members
of
the
Polar
Bear
Club
at
Coney
Island
，
New
York
are
usually
about
the
age
of
60
．
Members must
satisfy two requirements
．
Fir
st
，
they must get along well
with everyone else in
the
group
；
this
is
very
important
because
there
are
so
many
different
kinds
of
people
in
the
club
．
Polar Bears
must also agree to swim outdoors at least twice a
month from November through
February
．
Doctors don't agree about the medical
effects of cold
﹣
winter
swimming
．
Some are worried
about
the
dangers
of
a
condition
in
which
the
body's
temperature
drops
so
low
that
finally
the
heart
stops
．
Other docto
rs
，
however
，
point out that there is more danger of a
heart attack during summer
swimming
because
the
difference
between
the
air
temperature
and
water
temperature
is
much
greater
in summer than in winter
．
The Polar Bears themselves are
satisfied with the benefits of
cold
﹣
water
swimming
．
They say
that their favorite form of exercise is
very good for the circulatory
system
（循环系统）
because it
forces the blood to move fast to keep
the body warm
．
Cold
﹣
water swimmers usually turn bright
red after a few minutes in the
water
．
A person who turns
blue probably has a very poor circulatory
system and should not try
cold
﹣
water
swimming
．
The
main benefits of cold
﹣
water
swimming are probably
mental
．
The Polar Bears love
to swim
all year
round
；
they find
it fun and relaxing
