Please choose the correct ending to complete the given sentence: Health: [header] How to reduce edema during pregnancy [title] Stay off your feet as much as possible. [step] Standing or sitting with your feet flat on the ground can exacerbate edema because growing pressure on your veins hinders the return of blood to your heart. Avoid standing or sitting with your feet flat on the floor for long periods, which may help reduce edema, especially in your feet and ankles.

Ending1: [substeps] Try to add at least one inch of floor space between your feet to limit impact on the blood vessels. Make sure your toes are resting on ground level rather than the floor. Ending2: If you will be doing this for a long period of time, it is best not to do so while pregnant. Excess fluid can slow blood flow and causes edema to worsen. Ending3: [substeps] It is impossible to not be on your feet at times. If you are standing, try and take sitting breaks and rotate your feet and ankles while you do to help circulate the fluid. Ending4: [substeps] Sitting in shoes can also help you reduce edema. Stand in your barefoot heels if you are sitting and it is soft, as edema is hot to the touch on your feet.
