5Rapid and Weak Pulse
Heat exhaustion may also affect the operation of the heart and the cardiovascular system. Due to excessive sweating, dehydration would reduce the volume of blood in the vessels. As a result, your heart has to work harder to deliver sufficient blood to other vital organs in the body. When this occurs, you would feel a quicker and weaker pulse. The heart may race, pound, or flutter really hard. To measure the pulse, you can place the middle and index fingers on the vein located inside the wrist. A heart rate of more than 100 beats each minute is typically considered to be high. Make sure to visit your healthcare provider to avoid further complications. [5]
