Exercising In The City? Don't Get Exhausted; Take It Inside
As
environmentalists have pointed out, it can be as dangerous to be
outdoors behind a city bus -- walking or bicycling – as it is to
be in front of one. All the exhaust and smoke – even when they
have been reduced by clean-air technology – can damage a person's
health. The dangers of urban air pollution are of special concern to
those who exercise by running, bicycling or skating. These individuals,
while trying to help their bodies through exercise, should take care
that they do not harm themselves through exposure to air pollution.
