prevented if possible.

The tendency for hypertension and arteriosclerosis to occur early in
life in patients who have suffered some serious acute infection,
whether blood poisoning, typhoid fever, or other, shows that in all
probability in these acute illnesses the internal secretions are so
disturbed that the suprarenal activity is greater than normal, while
the thyroid activity may be less than normal, and hypertension is
the consequence. Therefore, these infected patients who recover
should probably have a longer convalescence in order for the more
delicate structures of the body, such as the internal secreting
glands, to have a better chance to recover and become normal.

The enumeration of these causes and the causes that have been
mentioned before not only suggest, but also direct the treatment of
hypertension after it has occurred. The most important of all
treatment for hypertension is rest. That means for an individual,
well except for his hypertension, a vacation, that is, a rest from
physical and mental labor. For a patient who is in serious trouble
from hypertension, bed rest is the most important element in the
management. As has been previously shown, good sleep lowers the
blood pressure, and Brooks and Carroll [Footnote: Brooks, Harlow,
and Carroll, J. H.; A Clinical Study of the Effects of Sleep and
Rest on Blood Pressure, Arch. Int. Med., August, 1912, p. 97.]
showed that the greatest drop in blood pressure occurs in the first
part of the night's sleep. In other words, a patient who lies awake
long loses the best part of his night's rest as far as his
circulation is concerned. This is one more reason for abstinence
from tea and coffee in the evening by those patients who are at all
disturbed by the caffein. On the other hand, patients who are not
