Move About the Cabin

Taking a long flight soon? Get up and move around when possible, urge researchers at Johns Hopkins University. Writing in the Journal of Acquired Immune Deficiency Syndromes, they report that deep vein thrombosis'dangerous blood clots that form in the legs'are 10 times more common in HIVers. Previous studies have also shown that sitting in an airline seat for hours at a time significantly boosts the chances for developing the condition. So unless that seat belt sign is illuminated, be sure to get up occasionally and move about. (But don't forget to buckle up when you sit back down!)
