Pressure on
U.S. Air Force Airman 1st Class Blake Ashford, a 35th Medical Operations Squadron aerospace medical service technician, checks a patient’s blood pressure at Misawa Air Base, Japan, March 14, 2018. When blood pressure is high, it puts extra strain on the arteries and heart. Over time, this strain can cause the arteries to become thicker and less flexible and weak.
