because it reduces oxidation.

6. Excessive exercise of the body, and overwork either of body or of
mind, should be avoided, especially during those seasons when a sudden
fall of temperature is of frequent occurrence. For exhaustion, whether
physical or mental, means loss of motion in the organism; and loss of
motion is the same as loss of heat.

One further consideration, suggested by the subject of this paper, has
reference to the bearing of the public toward the labors of the
medical man in meeting the effects of the low wave of heat. The
public, looking on the doctor as a sort of mystical high priest who
ought to save, may often be dissatisfied with his work. Let the
dissatisfied think of what is meant by saving when there is a sudden
fall in the thermometer. Let them recall that it is not bronchitis as
a cause of death, nor apoplexy, nor heart disease, as such, that the
doctor is called on to meet; but an all-pervading influence which
overwhelms like the sea, and against which, in the mass, individual
effort stands paralyzed and helpless. When the doctor is summoned the
mischief has at least commenced, and, it may be, is so far over that
treatment by mere medicines sinks into secondary significance. Then
he, true minister of health, candid enough to bow humbly before the
great and inevitable truth, and professing no specific cure by nostrum
or symbol, can only try to avert further danger by teaching elementary
principles, and by making the unlearned the participators in his own
learning.--_The Asclepiad._
