HOW TO MAINTAIN THE SKIN IN HEALTH. If the skin then, is an emunctory of so much consequence, as we have endeavoured to shew it to be, it stands to reason, that even the impartial performance of its functions, is incompatible with healthful existence. One might go farther and boldly aver, that a person who is a stranger to the bath, is as much to be pitied as a being with only one lung; both may exist, neither live. On the other hand, it cannot be denied that there are thousands of men and women in these islands, who seem to enjoy a large share of robust health, and who possess what assurance companies would call, "good lives," but who never indulge in the luxury of either a bath or a bedroom tub. But it will generally be found, that these people belong to the out-door working classes, who take abundant exercise in the open air, people whose pores are kept patent by the toil they undergo, and who, moreover, possess capacious lungs, substantial livers and healthy kidneys. Nevertheless, did these same persons make a practice of constantly using some form of bath, they would throw far less strain upon their internal organs, their blood would be purer, and their minds consequently lighter, and they would stand far less chance of catching cold, and succumbing to inflammation of some vital part. A person whose skin is not in easy working order, and who depends upon exertion and exercise alone, for keeping it up to the mark, must, if thrown on a bed of sickness, have a harder struggle for life than one whose skin is, in every sense of the word, a healthy one. Everything seems to point to the conclusion that the health of the skin is a matter of paramount importance to the individual, we cannot therefore be wrong if we devote this chapter to the consideration of the best means within our reach, of maintaining it in a sound and vigorous condition. So intimate is the connection between the skin and internal organs of the body, and so constantly and incessantly do they act and re-act on each other, that the state of the former may generally be taken as a key to the condition of the whole system. If the skin be dry, harsh, hot or in any way possessed of an uncomfortable feeling, the general health is, for the time being, out of order, or if it be cold or rough and chilly, the health must be below par, even although that state of being should be but momentary. A feeling of warmth, comfort and geniality, pervades the skin of the man who is well; deprived of this feeling he is deprived of health, he is ill, acutely subacutely, or chronically ill. DIET:--The influence of diet on the skin is very great.
