CHAP. XV. Of Motion and Rest.
HEre Physitians admonish us, that by the name of Motion, we must under∣stand * 1.1 all sorts of exercises, as walking, leaping, running, riding, playing at tennis, carrying a burden, and the like. Friction or rubbing is of this kinde, which in times past was in great use and esteeme, neither at this day is it altogether neglected by Physitians. They mention many kinds of it, but they may be all reduced to three, as one gentle, another hard, a third indifferent; and that of the whole bo∣dy, * 1.2 or onely of some part thereof. The friction is called hard, which is made by the * 1.3 rough, or strong pressure of the hands, spunges, or a course and new linnen cloth: it drawes together, condensates, bindes and hardens the flesh, yet if it bee often and long used, at length it rarifies, dissolves, attenuates and diminishes the flesh, and any o∣ther substance of the body; and also it causeth revulsion, and drawes the defluxion of humors from one part to another. The gentle friction which is performed by the light rubbing of the hand, and such like, doth the contrarie, as softens, relaxes, and * 1.4 makes the skinne smooth and unwrinckled, yet unlesse it be long continued it doth none of these, worthy to be spoken of. The indifferent kinds consisting in the meane betwixt the other two, increaseth the flesh, swells or puffes up the habite of the body, * 1.5 because it retaines the bloud and spirits which it drawes and suffers them not to be dissipated.
The benefit of exercise is great, for it increases naturall heate, whereby better di∣gestion * 1.6 followes, and by that meanes nourishment, and the expulsion of the excre∣ments, and lastly, a quicker motion of the spirits, to performe their offices in the bo∣die, all the wayes and passages being cleansed. Besides, it strengthens the respirati∣on, and the other actions of the body, confirmes the habite, and all the limbes of the body, by the mutuall attrition of the one with the other; whereby it comes to passe they are not so quickly wearied with labour. Hence we see that Country people are not to be tired with labour.
If any will reape these benefits by exercise, it is necessary that he take opportunity * 1.7 to beginne his exercise, and that he seasonably desist from it, not exercising himselfe violently and without discretion; but at certaine times according to reason.
Wherefore the best time for exercise will be before meate (that the appetite may be encreased by augmenting the naturall heate) all the excrements being evacuated, lest nature being hungry and empty, doe draw and infuse the ill humors contained in the guts, and other parts of the body, into the whole habite, the liver, and other
