I recently had a terrible disagreement with someone and everytime I think about it I start shaking and my heart starts pounding from adrenaline, which according to Google is unhealthy. But our hearts are accelerated when exercising, which is supposed to be a good thing – so what is the difference?
In: Biology
Your heart pumps because adrenaline is being released, blood is flowing all over your body including your muscles for you to use, in case of danger. If you don’t move, your body thinks you’re in significant danger and not doing anything, so it responds negatively out of confusion, which makes you more unhealthy and worse off.
It’s more about the cortisol released from those emotions. It literally ages you twice as fast and aren’t good for your body
Think of throwing a baseball, throw it really hard like trying to strike out a batter. Now do the exact same thing and intensity with an empty hand. It’s hurts like hell and causes eventual damage. The ligaments and muscles have something to push against, your heart and vessels need the same thing.
I do t know but I have the heart problem
that you get from the former. It’s called Inappropriate Sinus Tachycardia.
Should amputated individuals not exercise then?
I’ve been told by my therapist that adrenaline is stored and not released. So we have to get it “out” by excercising/elevated heart rate.
The Relaxation Response is a really great book I’m currently reading about the physiology and long-term physical effects of stress. It explains the relationship between blood pressure and different aspects of mental health. Pretty solid read just to understand what’s going on within
One good example I’ve heard, is that when you encounter something fearsome, you’ll get a shot of adrenaline to fight or flight with. But you can see the these and you know when it’s gone so the elevated heart rate and blood pressure soon drop.
With stress or anxiety, it’s not a clear physical threat. You might stress over your job, that you need to do this project, and do it well, or the company will go under, and you’ll lose your job, and you’ve got bills to pay, and the job market is not looking good right now, etc. So your brain is thinking over all the bad things that could happen, and starting to generate a fear response because you’d obviously fear this chain of events happening. Yet it’s a long term issue, and there is no clear end in sight. Certain jobs might put you in a position where job security is not great and so you are always stressed. So your brain is telling your body bad things will happen, you’re in danger, and cortisol the stress hormone is released. Your body is constantly got elevated heart rate and blood pressure, because it doesn’t understand the threat. And there is nowhere for this to go.
Under exercise however, your heart is just responding to your needs and working more as it is needed, all that work is done just for those muscles you are using
Stress and anxiety restricts your veins, making them smaller and harder to pump blood throughout the body. Exercise just increases blood flow that way the body has more access to oxygen
Considering the plumbing example, why is a sauna considered to be healthy. As it increases heart rate with no outlet for blood pressure
