Remaining quietly in closely heated rooms frequently causes disease in the pregnant woman. Without exercise, food cannot be assimilated, the processes of depurition are imperfect, the muscles lose tone and power, and the nervous system becomes prostrated. On the other hand, excessive labor often proves injurious. Some muscles are overtaxed and local strains produced. It is difficult to give directions applicable to all cases. Exercise should not be carried to actual fatigue. A weariness that _makes the bed feel good_ can do no harm. General housework is desirable, avoiding the more laborious portion, like washing, scrubbing and heavy lifting. In housework one brings into action nearly all the muscles of the body, with the exception of some of the trunk and those used in deep respiration. Even these would not lack development if clothing caused no restrictions. In the home work a woman reaches, stoops, turns, walks, lifts and climbs stairs. Housekeeping usually interests a woman during pregnancy if at no other time. She is _nest building_, and the home work is a labor of love. She rests in the quiet of a cozy, retired home. How easy to perform the duties that the heart sanctions and impels!
