When you exercise, there are dramatic changes that are taking place in your cardiovascular system. The most dramatic change experienced by people who exercise strenuously is the drop in their pressure. But why does this happen? Read this article to know why does blood pressure drop after exercise.
Before we get on with the reason why blood pressure drops after exercise, you need to know what exactly blood pressure is. According to NHLBI, “Blood pressure is the force of blood against the walls of arteries. Blood pressure is recorded as two numbers—the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats).”
There are two main reasons that could possible explain,” Why does blood pressure drop after exercise”:
- When you exercise the body temperature increases and that requires more intense blood flow in order to lower the temperature after finishing the strenuous workouts. As the vessels of blood in the skin increase, the volume of blood in the heart automatically decreases which ultimately lowers the blood pressure.
- Secondly, during the workouts, the concentration of lactic acid in the bloodstream remains high; this increases blood vessels and therefore lowers blood pressure by reducing the volume of blood in your heart.
To cut the long story short, when one exercises, the muscles that are in use require more blood and oxygen to function and it is this pressure that forces one’s heart to beat faster. This results in pumping out of more blood. So, whenever the heart rate increases, the blood pressure on the arterial walls also increases. And, once you as soon as you stop exercising, the blood vessels begin to relax and ultimately reduce the amount of resistance and pressure on the walls.
It is thus, very important to dedicate the last minutes of your work-outs in cooling your body temperature down or else you may faint. If doctors are to be believed then a sudden change in blood pressure may increase the risks of heart attack and other cardiovascular diseases. So, the good way to avoid those risks is to warm up before starting your exercises and to perform some cool down routine when finishing your workouts.
