41. Cause of Mouth Breathing. Some people find it difficult to
breathe through the nostrils on account of growths, called adenoids,
in the nose. If you have a tendency toward mouth breathing, let a
physician examine your nose and throat.
Adenoids not only obstruct breathing and weaken the whole system
through lack of adequate air, but they also press upon the blood
vessels and nerves of the head and interfere with normal brain
development. Moreover, they interfere in many cases with the hearing,
and in general hinder activity and growth. The removal of adenoids is
simple, and carries with it only temporary pain and no danger. Some
physicians claim that the growths disappear in later years, but even
if that is true, the physical and mental development of earlier years
is lost, and the person is backward in the struggle for life and
achievement.
