Why Does Our Heart Rate Drop?
What causes our heart rate to drop?
The human body has an automatic response that lowers blood pressure when we're stressed. This is called "fight or flight" response. Learn how this works and why it helps us survive in dangerous situations.
And what does it mean when we feel like we're running out of energy?
When we're under stress, our bodies release adrenaline into our bloodstream. Adrenaline makes us more alert and ready to fight or flee. It also triggers other changes in our bodies, such as increased breathing and heart rate. These physiological responses help us cope with stressful situations. However, these same responses can make us feel tired and drained.
The Basics of Cardiovascular Physiology
In addition to adrenaline, another hormone called norepinephrine (also known as noradrenalin) plays an important role in regulating blood pressure and heart rate. Norepinephrine is released by the adrenal glands when we're stressed. This hormone helps regulate blood pressure and heart rate by increasing the force of contraction of the heart muscle.
When Is Your Heart Rate Low?
If your heart rate drops below 60 beats per minute, it's considered low. A normal resting heart rate is between 60 and 100 beats per minute. However, some people with anxiety disorders have heart rates that are lower than 60 beats per minute even during rest.
Causes of Low Blood Pressure
Low blood pressure (hypotension) occurs when there isn't enough blood flowing through the body. It can happen because of an injury, infection, or other medical condition. In addition, medications, alcohol, caffeine, and stress can also cause hypotension.
Causes of High Blood Pressure
Hypotension can lead to low blood pressure. This happens when the heart pumps too much blood into the arteries instead of the veins. As a result, less blood flows back to the heart. If left untreated, hypotension can lead to organ damage and even death.
