“Compression sleeves can be worn during all sorts of exercise and even on a daily basis,” Dr. Jena Gatses, D.P.T., physical therapist, says. She notes that you might want to wear a compression sleeve while traveling, commuting, or working (especially if your job keeps you on your feet). And you might also want to wear one before, during, and after exercise. “Theoretically, you can keep a sleeve on all day if you wish,” Dr. Trentacosta says. “But having a very tight compression sleeve on your arm or calf can feel uncomfortable and restrict blood flow over time.” So pay attention to how you feel in the sleeve, and take it off if you start feeling uncomfortable.
