10 Surprising Things That Trigger “Fight-Or-Flight”

By Lissa Rankin MD  

Guest writer for  Wake Up World

You know that when you’re getting chased by a tiger, you’re almost in a car accident, your “to do” list is overflowing, and you’re burning the candle at both ends, your body’s “fight-or-flight” stress responses are going to get triggered. But you might not know what else will trigger stress responses in your body, and it’s important that you do!

As I explain in Mind Over Medicine: Scientific Proof That You Can Heal Yourself, the body has natural self-repair mechanisms that can fight cancer, prevent infection, repair broken proteins, protect your coronary arteries, and retard aging. But whenever the nervous system is in “fight-or-flight,” the body’s natural self-repair mechanisms are disabled!

The amygdala in your primordial limbic brain is your danger alert signal, and it hasn’t evolved to keep up with modern day society, so your amygdala can’t tell the difference between dangers that threaten life and limb and perceived dangers that are merely thoughts, feelings, or beliefs in your mind. As a result, your amygdala may be sabotaging your health, and you may not even know it!

So how can you avoid winding up in chronic repetitive stress responses? Here are some surprising “fight-or-fight” triggers to avoid.

1. Feelings of loneliness

As a species, we are tribal people, so from a survival perspective, being alone too much can signal the amygdala to trigger stress responses. Makes sense, right? If we’re dependent on the tribe to keep us safe, forebrain feelings of loneliness can activate the amygdala’s danger signal. Scientific evidence suggests that people who are part of a supportive community have half the rate of heart disease when compared to lonely people, and this may explain why.

2. Hunger

If you feel hungry, the message you’re sending your danger-seeking amygdala is “Houston, we have a problem! There’s not enough food!”   Of course, your fridge is full of food and maybe you’re fifty pounds overweight, and hungry because you’re trying to diet. But your amygdala is not smart. It can’t tell the difference. So boom- you’re in stress response, and your self-repair mechanisms are flipped off.

3. Selling your soul for a paycheck

You know that your job can be stressful. But it’s not so much being busy or working hard that will trigger your “fight-or-flight.” Sure, even a job you love can stress you out. But you’re much more likely to wind up in chronic repetitive stress response when your integrity is on the line.

4. A pessimistic world view

If you’re a glass half empty kind of person, your forebrain is communicating all kinds of scary messages to your amygdala on a regular basis, thoughts like “There’s not enough money,” “Nothing ever goes my way,” “Nobody really loves me,” and other Eeyore sorts of thoughts that stimulate stress responses in the body. In fact, optimists have a 77% lower risk of heart disease than pessimists, and this is probably why.

5. Toxic relationships

While loving relationships and a supportive community are calming to the amygdala and healthy for the body, you’re better off being alone than being in the company of people who stress out your nervous system. When you feel threatened in a relationship- not just physically, but emotionally- your nervous system interprets that as danger.

6. Worry-wart thoughts

Anxious, worried thoughts make the amygdala go ballistic. If you’re filling your brain with worried thoughts about the kids, the state of affairs in politics, whether or not your lover is going to break your heart, or how quickly the glaciers are going to melt, you’re certain to trigger stress responses.

7. Childhood traumas

You know those old childhood traumas that stick around if we don’t heal them? You may not even realize that subconscious thoughts arising from old traumas may be triggering your amygdala when you don’t even realize it. Triggers such as places, scents, songs, or other sounds that remind you of the trauma may trigger “fight-or-flight,” even if you’re completely unaware that it’s happening.

8. Unforgiven resentments

When you harbor resentments- against your ex, your mother, your boss, whoever- you give your amygdala fuel. Resentful thoughts are interpreted by the amygdala just like thoughts of food scarcity or a tiger on the loose.

9. Anger

It’s not just rage that will flip you into “fight-or-flight.” Even thoughts like “Someone just spilled red wine on my white carpet” can trigger your limbic system.

10. Feelings of helplessness

The amygdala likes to feel in control- after all, it’s the amygdala’s job to protect you from danger! So feelings of helplessness can land you in “fight-or-flight.”

If reading this list sends you into “fight-or-flight” just because you’re feeling all 10 of these things right now, don’t despair. This is where you get to be proactive! Awareness is key. Once you start to cultivate awareness of what triggers your own stress responses, you can be mindful about how you tend the garden of your mind so you can keep your amygdala calm and keep your self-repair mechanisms doing what they do best- keeping you healthy!

    For all these things, it might be helpful to get some Eckhart Tolle, in any form.

    And a BIG One that seems to have been overlooked here:

    **Lack of Sleep !! Not getting as much sleep as your body feels that it needs will almost certainly begin to activate and Trigger the brains primitive system; as it isn’t getting adequate rest necessary to function properly- it starts to rely on the more basic functional level of operating system.. leading to the primitive brain taking over, and the associated Fight/Flight/Freeze response will naturally kick in and start to dominate the person’s behaviors and actions.
    Of course, this is more easily forgotten about when running low on the fuel necessary to work properly, in terms of cognitive function and clarity of thought and understanding. ! 😉
