@. How long should q person stay in
the water when swimming at Sum-
mer resort?-O. S.
A. The Public Health Service says
that there is certainly little to be gained
from a health viewpoint by lolling in
the water for several hours at a time.
! To obtain the beneficial effects of a
swim one should not remain in the
water longer than 80 minutes at most,
this period being coupled with appro-
pirate short rest periods unless the
swimmer is unduly hardy and accus-
| toned to the vigorous exercise in
volved. The practice of drying off, "
often in a chilly atmosphere, is one to
be condemned because Of the possible
chilling of the body. 1t is much better
| to enter the water several times daily,
| taking brisk rub after each swim and
changing into dry clothes, instead Of al
lowing the clothing to dry on the body
as some do at the seashore.
