In some cases, bed rest during pregnancy simply means decreasing your activity level for a period of time. You might be free to move about the house, as long as you avoid lifting children and doing heavy housework. Depending on the demands of your job, you might even be able to continue working.
In other cases, bed rest guidelines are stricter. You might need to remain in a sitting or reclining position most of the time, only getting up to use the toilet or shower. You might not be allowed to work or do even light household chores until the baby is born.
If your health care provider prescribes total bed rest during pregnancy, you might need to lie on your side at all times — including when you eat. Personal hygiene might be limited to sponge baths and a bedpan. This type of bed rest might require hospitalization.
