Clothing, to promote health, should be: sufficient for comfortable warmth; not excessive in quantity or pressure; properly distributed over the body; suited to permit transpiration and moisture; changed often enough for cleanliness.
Some persons, with the idea of hardening themselves, wear as little clothing in winter as possible. This is perhaps well enough if they are very robust; but if not strong, they become chilled through and may be severely reduced in health.
Yet it is equally a mistake to keep one's self too warm, burdening the body with unnecessary clothing. The same is true of bed-covering, in respect to which people have very different needs. On the same night one may be satisfied with a single blanket, while another needs two or three. Every one ought to be warm enough to sleep comfortably.
