Experts explain why swelling in arms and legs rises in summer

Hot weather can cause swelling in the legs, feet and sometimes the hands during the summer, according to vascular disease specialist Laurent Martin. He said rising temperatures widen blood vessels, which can lead to fluid buildup, especially in people who sit or stand for long periods. Experts recommend raising the legs above heart level, moving regularly and avoiding long periods in one position to ease the discomfort. Nutrition and public health specialist Jean-Paul Reno said drinking enough water, reducing salt intake and avoiding tight clothing can also help. The article also notes that cold water or a lukewarm shower may provide relief in some cases. Medical evaluation is recommended if the swelling appears suddenly or comes with pain and redness.
