Heart rate is one of the ‘vital signs,’ and one of the most important indicators of health in the human body. It is the measurement of how many times per minute the heart contracts, called as beats or BPM (beats per minute).
Few notes on the cardiovascular system.
The heart and blood vessels are the two elements of the cardiovascular system they work together in providing nutrients and oxygen to the organs of the body. The synchronized actions between our heart and the blood circulation are mainly triggered to react from an external factor, that most of the times is called: Stress.
At this point we will break a bit the science and build our concept of the word STRESS, from the called vulgar Latin, strictia meaning tight, compressed, and drawn together.
Our society has been using this word to describe many different situations that are challenging or put us under pressure or even could be harmful. Those situations are most of the time uncontrollable and not necessarily negative, our system is designed to handle certain amount of stress as a mechanism of adaptation.
The response of our body to different stimulus is actually a chain of reactions that activate the “FIGHT” mode.
Now imagine this 3 massive Lions coming for you… running full speed, hungry and instinctively they see you as a meal…
Let’s try to think what are the changes that are going to happen in our body to react, first we will have a very quick release of many hormones called “stress hormones”, such as Cortisol also our blood pressure will increase, our digestion system slows down, Immune System “shut down” and because our system adapt to deliver quick energy into the muscles and organs we start to convert glycogen to glucose, and at the same time our HEART RATE increase.
So now we have our system “Ready to Fight”.
We all have to agree, that there is nothing wrong to run away from a Lion, and we are very thankful that we don’t have to think about to produce those reactions, they natural and part of our survival package.
Did you realise that the situation on the example required a physical reaction from us; in this case RUN AWAY from those lions is probably the only solution. All those reactions from our body are a preparation to allow us to run or act as fast as possible, and physically be able to save our life.
What is the difference when the solution is not physical?
Let’s bring another example, imagine now that you had big problem with your work or family, or are going through a hard time…
How does our body read this information?
Here is something interesting, for our body there is no difference between the 3 lions or our work problem, the way our system will react is related to the intensity of the situation, but the reactions are 99% the same. Trying to solve a big problem at work can have the same impact in our body as running away from lion, because our Central Nervous System does not differentiate the situation, as both impact our system the same way.
Both situations are called Acute Stress, meaning those episodes that happen once in a while, we react, adapt and once they are gone our body comes back to the normal state. However, there are some situations that are constantly generating stress in our lives.
Chronic stress, or a constant stress experienced over a prolonged period of time is considered one of the biggest problems of our modern society. The “hunting” for better position, the need of money plus the natural life situations can easily cause chronic diseases generated by the constant “alert” state of our body.
What are the signs that we should look then?
Using those physical reactions that I mentioned earlier such us:
- Cortisol release: Stress Hormone
- Slow down digestion system
- Immune System “shut down”
- Conversion of energy into glucose (quick energy release)
- Increase of blood pressure
- Increase of Heart Rate
Each one of those reactions will generate a different consequence in our body, and over time because a more serious health problem. In general, a chronic stress could reflect:
- Irritability, which can be extreme
- Fatigue
- Headaches
- Difficulty concentrating, or an inability to do so
- Rapid, disorganized thoughts
- Difficulty sleeping
- Digestive problems
- A perceived loss of control
It is important to understand also, that chronic stress is a process that is built over years and has very deep impact in our body, and some situations are probably impossible to control so the idea of trying to “Not get stresses” it is also one of the mistakes that our society have. As we saw, our system is prepared to overcome the stress, to fight and adapt, there is nothing wrong in having a hard time to solve a problem, to have a difficult conversation or to confront someone, this is normal and part of our live we can’t and we should not run away from that.
Some stressful situations are the foundation of our life and will create memories to be used in the future. Living those experiences, exploring with open mind, searching for the “learning” from each new moment. Our body doesn’t know if something is really a stress unless we consciously categorized as a harmful situation this is also important to understand. A situation become a stressful episode when we consciously perceive that moment as a pressure or complication, that is why each person has completely different perception of how stressful the same situation can be.
What can we do?
Of course the solution is not to escape from the situations because we will not be able to avoid things to happen around us, so the moment that we understand and accept that something is really happening and there is no way that we can escape, avoid or stop, we transform this situation in a positive experience in terms of learning.
To position ourselves one step back, trying to analyze from “outside” what is really what us creating the stress, allow our system to create a new pattern to the same episode that once was a stress, generating an enormous amount of reactions, now is a situation of our life, that is new; it will demand a new skills; it will take us out of our comfort zone; it will made us stronger, it will make us better…
Hope you enjoyed!
