Avoid wearing or carrying anything that compresses or squeezes your affected arm and/or hand. Tight sleeves or bracelets can constrict circulation in your arm, contributing to fluid build up which can lead to lymph node swelling. Forcing the affected arm or shoulder to bear excessive weight can also contribute to lymphedema. Be sure to carry a light bag or purse and avoid handling heavy bags, (especially avoid carrying them on the shoulder or the crook of your arm) to minimize pressure and constriction on your arm. Blood pressure cuffs measure your blood pressure by constricting around your arm, temporarily stopping circulation. Since, to avoid lymphedema, you want to maintain healthy, free circulation in your arm, it's a bad idea to take blood pressure readings in the affected arm, which can contribute to further swelling and fluid buildup. Try to avoid exposing yourself to extreme temperatures, which can disrupt normal circulation to your arm. For instance, it's recommended that you avoid using hot tubs, saunas or steam baths. When you bathe, use warm or lukewarm (rather than hot or cold) water.  Also avoid burning or irritating the affected arm in any way by exposing it to extreme temperatures, which can increase fluid buildup . Apply sunscreen at least SPF 15 during the day. This prevents sunburns, which can irritate the skin on the affected arm (and, in extreme cases of lymphedema, even cause the skin to break down). When sitting for a long period of time or sleeping, you may want to elevate the affected arm. Use a pillow, another  similarly-sized object, or a medical arm support to prop your arm in a position that has it comfortably resting above your heart. This will naturally and safely decrease the the circulation to your arm, helping to minimize fluid buildup. Be sure to avoid lying on the affected arm for an extended period of time. If needed, pack extra pillows behind your back or around your sides to prevent yourself from unconsciously turning over while you sleep.
