How to decrease swelling during pregnancy

So far in my pregnancy I haven't been swollen (which I am so grateful for).  I'm only a little over halfway so there is a huge possibility it will still happen (doctors say some swelling is completely normal).  Here are some tips from American Pregnancy Association of how to prevent your body from swelling up like a balloon:

• avoid standing for long periods
• minimize outdoor time when it is hot
• rest with your feet elevated
• wear comfortabe shoes, avoid wearing high heels if possible
• wear supportive tights or stockings
• avoid clothes that are tight around your wrists or ankles
• rest or swim in a pool
• use cold compresses on swollen areas
• drink water, which helps flush the body and reduce water retention
• minimize sodium (salt)
