When you are afraid, you start going into fight or flight mode. Your body starts prioritising what is needed for immediate survival - screw routine body functions, if you don't make it past the next few moments there won't be a routine to return to. You stop digesting food. Cell repair slows or stops. You stop producing saliva, which is why your mouth goes dry when you're nervous just before making a speech or going into a difficult conversation. Your heart rate and breathing increase to ensure better blood flow. A cocktail of hormones like epinephrine and oxytocin are cued up and produced, which amplifies your body's ability to act (and remarkably, in the case of oxytocin, reminds you to seek help).
Don't be mistaken about what happens when you feel fear. Your body is readying itself to help you face what you fear in the way it knows how.
What causes us to feel fear?
1) Fear occurs to us unconsciously. Do you pause to think, hey, very angry looking snake! Maybe I should be scared. Of course not, it would be too late! Fear becomes much clearer when we examine what happens inside your brain. When you are afraid, the fear/anger/aggression/anxiety centre of your brain - the amygdalas (get used to this name, it's gonna keep popping up) lights up. And we've covered all the changes that happen in your body: your blood pressure, your hormones, your heart-rate. But remember how amygdala is like a train interchange with direct routes to different parts of your brain? There is a direct neural link between our amygdala and your pre-frontal cortex, the rational thinking part of your brain. And if we look closely enough or we think things through, sometimes we realise, argh! it's not an angry snake, it's just a prank toy that your annoying friend had thrown at you. Or if you've handled angry snakes enough times, your amygdala does not light as much. Your blood pressure and your heart rate do not increase as much, you realise what you need to do is to stay calm and slowly back away.
Finally, notice how fear, anger, aggression, and anxiety are processed by the same part of the brain, the amygdala. This is no coincidence. These 4 emotions are closely tied to one another; aggression maybe triggered because one is nervous, angry, or fearful. Being fearful may cause one to react angrily, as a self-defense mechanism. Fear, like all our emotions, happens to us. Mostly, we can't control how it originates. But we can control how it develops by understanding what exactly is causing fear and by choosing the response that dispels it
2) We fear what we are unconfident or uncertain about. Think back on your ancestors doing something they weren't confident or certain off - hunting a massive animal without a weapon, or eating a berry they've never seen before. Doing so would mean a very high chance of seriously harming themselves. Today, after many cycles of evolution, we have been wired based on these experiences.
Think about it. Are you ever fearful of something you've done before, and are good? Brushing your teeth, putting on your clothes, indulging in your favourite hobby (whatever it is)? Of course not. You know you can perform these functions easily. You are confident.
But many of us would have felt fearful and anxious the first time we ventured into something new: using a pair of chopsticks, riding a bicycle, swimming, going on a first date. We were uncertain about these functions, and we were not confident about performing them. However, once we have demonstrated to ourselves that we are able to perform these tasks, we are no longer afraid. The same applies to more challenging tasks. Some of us struggle with: public speaking, starting a business, having a very difficult conversation with the CEO... You are uncertain and unconfident if you can succeed. But once you have proven to yourself you are able to do it, even for the more challenging tasks, you are no longer afraid. People might start off feeling scared about public speaking, but after speech 3797, you're pro The catch, of course, is that sometimes, we are too scared to start.
Even if we were certain of something OR confident about something, many of us will still feel some amount of fear. We might be theoretically certain how we should use a pair of chopsticks, but if we have never succeeded in using them properly, we remain unconfident and will still feel nervous if we had to use them, especially when others are observing. You might also be confident about
3) we fear what is painful. Boxer. climbing 100 flights of stairs or doing 100 burpees. But pain is not just physical but mental. Failure is painful. Being judged is painful.
This is why you procrastinate. You either fear what you have to do bevause you don't know how to do it (you don't fear brushing your teeth for example), or you fear doing something becaue you know it will be effortful
4) we fear what we cannot control

How much do you love your significant other?
Tell me 10 reasons why
"How much do you love your significant other?" It's a deeply personal question. No one really knows the answer but you.
​
But here's the thing. Can a strange change your mind about how much you love your significant by asking just one neutral question? Let's take a look at some examples.

Let's split everyone up into 2 groups.
For the first group, we ask: write down 3 reasons why you love your significant other.
For the second group, we ask: write down 10 reasons why you love your significant other.

Having answered that first question, we then ask everyone the second question - the one we want to find out: how much do you love you significant other.
​
Now you would expect fairly similar scores between Groups A and B - who are both randomly selected, and of the experiment is repeated many times over with different Groups A and B.
But the answer is always the same. Group A always scores higher than Group B on average.
​
And there is a reason for this. Most of us can easily come up with 3 reasons we love our significant other. And coming with these 3 reasons affirms our love: we love this person and as you can see, we can easily explain why.
Think about what happened with the 10 reasons group. It's hard to come up with 10 reasons for anything on the spot. People find it increasingly difficult to think of the next reason, and the next reason, until you get to 10 reasons. The realisation that it's quite difficult to think of 10 reasons, and the increasing difficulty in thinking as you try to think of your next reason causes you to second-guess yourself, it creates doubt in your mind.
And this really reaffirms a theme that is continually presented across these pages. We all believe we are making every decision consciously and deliberately. But in truth, what happens is that many things are affecting ou decision making and thought process all the time. Even a seemingly innocuous question about a deeply personal issue can cause us to change our minds, even though nothing in reality has changed at all.
Think about how people can be manipulated just by the question asked:


Consider the 2 scenarios above.
If your significant other wants to buy something which you disagree with, can you change his/her mind just by asking the right question? What if you were conducting a course and you wanted good reviews scores? Again, nothing in reality changes, but the question change our perception of reality?
​
One final example:
​

Let's say you ask a group of people how many times they floss.
But with one variable - the time of measure. For some people, you ask them how many times you floss a day, and for others, you ask them how many times they floss a month. Everything else it the same.
​

For almost everyone in the first group, their answers will be on the left side of the scale. No one glosses 9 times a day (I hope!)
For almost everyone in the second group who do floss, their answers will be on the right side of the scale.
This seems pretty obvious and straightforward, but this also affects our perception of whether to see a dentist. The first group, because of where their answer lies on the scale, are more inclined to feel below the norm. The second group on the other hand, because of where their answers lie on the scale, are more inclined to feel better than the norm.
And this perception that influences how we assess ourselves, even though, as you are probably already repeating in your head - nothing, in reality, has changed. ​
