Scientific Explanation For Why Introverts Need Much More Alone Time Than Extroverts

Scientific Explanation For Why Introverts Need Much More Alone Time Than Extroverts

Picture this: You’re at a party. A few of the people you know fairly well, most are mild acquaintances and the rest you’ve never before. How do you interact?

The way you view and respond to social situations is the primary indicator on whether you are an introvert or an extrovert.

What is the difference between an introvert and an extrovert?

There are several popular misconceptions surrounding introversion and extroversion. And because of this, introverts, in particular, are often misunderstood. They are often branded as shy, aloof, and even antisocial. While extroverts are described as bubbly, friendly, charismatic, and fun.

But it is important to understand that introversion and extroversion are not personality types in and of themselves — rather, they’re important pieces of the personality puzzle. They also aren’t the only two options — there’s a whole spectrum of introversion and extroversion, and almost no one is purely introverted or pure extroverted. In fact, science has coined a new term to describe those exhibiting an even mix of traits from both intro and extroverts; they are the ambivert.

    What are the causes of introversion and extroversion?

    Scientist believe that the causes of introversion and extroversion lie in the brain and how it responds to dopamine. Dopamine is a neurotransmitter that helps regulate the brain’s pleasure and reward system. It enables us to recognize rewards and move towards them. It is part of the guidance system for our emotions.

    In social situations, the extroverted brain is stimulated. It views social interaction as rewarding and responds as such. The thought of positive social interaction floods the brain with dopamine and drives the extrovert towards interaction as it is seeking to be rewarded.

    The pleasure center of an introvert brain functions the same way—but with one very distinct difference. Extroverts have a more active dopamine reward network than introverts—meaning extroverts need more dopamine to feel pleasure. When dopamine floods the introvert brain, introverts do experience the feeling of excitement but it is accompanied by the feeling of being overwhelmed.

    Dr. Marti Olsen Laney explains in her book The Introvert Advantage: How Quiet People Can Thrive in an Extrovert World, “for introverts, too much of a good thing really is too much. They feel overstimulated when dopamine floods their brains.”

    The introvert brain is more responsive to the neurotransmitter, acetylcholine. Like dopamine, acetylcholine is also linked to the brain’s pleasure center. The difference is, acetylcholine makes us feel good when we turn inward. It powers our abilities to think deeply, reflect, and focus intensely on just one thing for a long period of time.

    Research tells us that everyone’s nervous system has two modes: parasympathetic and sympathetic. When we use the parasympathetic side (nicknamed the “rest and digest” side), we feel calm and are focused inwardly. Our body conserves energy and withdraws from the environment; muscles relax, energy is stored, and our heart rate and blood pressure slow. The sympathetic side (a.k.a “full throttle”) puts us in a state of fight or flight. Our pressure and heart rate are elevated, we are alert and poised for action.

    Introverts thrive when they are operating in parasympathetic mode. This is the reason for the constant desire introverts have to be alone. Their desire and pension to engage in quiet, thoughtful activities away from others is not antisocial or moody behavior. It is a physiological need they have that is driven by their brain chemistry and function.

    When introverts are deprived of their alone time they can experience:

    • Fatigue
    • Mental and physical exhaustion
    • Inability to concentrate
    • Irritability
    • Increased anxiety
    • Depression

    The causes of introversion and extroversion are directly linked to how our brains operate and respond to neurotransmitters. So the best thing you can do for the introvert that needs time by themselves is to leave them alone.

    How to Reinvent Yourself and Change Your Life

    How to Reinvent Yourself and Change Your Life

    There will always be times in your life when you may need to learn how to reinvent yourself. This could come when you experience a big change, such as leaving your job, moving on from a relationship, transferring to a new home, or losing a loved one. If you are going through a major shift in your life, you may have to find new ways of thinking or doing things, or risk failing to reach your full potential.

    “When something bad happens, you have three choices. You can let it define you, let it destroy you, or you can let it strengthen you.”

    Many people who dared to leave their old unhappy lives enabled themselves to pursue their passions and find a renewed zest for living. You can also achieve the same if you take a leap of faith and make things happen for yourself.

    To help you always be at your best wherever you may be in your life, here are some practical tips on how to reinvent yourself.

    The Reinvention Checklist

    Before embarking on a journey of self-reinvention, you need to make sure that you have everything that you need to make the trip bump-proof. These things include:

    Resilience

    Problems and obstacles are guaranteed to happen. Some of them will be difficult and may knock you off course; the important thing, however, is that you learn from these difficulties, never lose focus, and always get back up. This requires building resilience to get through the tough times.

    Support

    Humans are social beings. Although it is important that you learn to rely on yourself when facing any challenge, it is also important to have a support team that you can lean on to give you a boost when things get too tough and to correct you when you’re making mistakes.

    The key is to find the right balance between independence and dependence. Don’t be afraid to be vulnerable and share the difficulties you’re facing. When you open up, you’ll find the people who are really going to be there for you.

    Self-Care

    During the process of learning how to reinvent yourself, you will have to pull yourself away from your old comfort zones, habits, roles, and self-perceptions. This can be difficult and cause you to question your self-worth, so it’s important to engage in self-care to maintain a positive outlook and keep your mind and body healthy as you face the challenges that await you. Self-care can include:

    • Participating in a hobby you enjoy
    • Spending time with your support system
    • Taking some time to walk in nature
    • Practicing loving-kindness meditation

    Find what works for you and what helps you feel like your true self as you seek a reinvented version of you.

    How to Reinvent Yourself

    Once you’re sure that you’re equipped with all the tools in the self-reinvention checklist, you can begin your journey of learning how to reinvent yourself.

    1. Discover Your Strengths

    This step provides valuable information on how you deal with certain situations. If you have this information, you will be able to manage difficulties more efficiently.

    To find out what your strengths are, you can ask your friends and colleagues for feedback, engage in self-reflection, or try these 10 Ways to Find Your Own Personal Strengths.

    2. Plan

    This step calls for a thorough assessment of your current emotional, psychological, and financial status so that you can develop plans that are realistic and practical.

    It’s okay to have ambitious dreams, but your plans have to be realistic. Making use of SMART goals can help you plan your life better.

    You can also consult your mentor or life coach for practical tips and advice.

    Ultimately, you’ll want to create specific long-term and short-term goals that you can create milestones for. By doing this, you’ll lay out a specific roadmap to your reinvented self.

    3. Try Things Out

    Sometimes, we don’t know if solutions actually work until we try them out. This is why it is important to experiment whenever possible, especially if you’re dealing with a career change. You may need to simply experiment in order to find the things you like. This can be the same with hobbies. If you’re not sure what you would like doing, accept invitations from friends to join them in their favorite sport or take a class, like pottery or photography.

    By seeing what’s out there in any area of your life, you’ll have a better chance of finding the things you enjoy and the goals you want to create.

    4. Manage Your Finances Well

    Changes may require a bit of money. If you’re shifting to a new career, you may have to pay for training. If you’re going through a tough divorce or having a hard time dealing with the death of a loved one, you may have to pay for therapy. If you’re moving to a new home, you’ll definitely have to pay a whole lot of expenses.

    All of these things are possible, but it will require a bit of money savviness as you learn how to reinvent yourself. If you have that cushion, you’ll feel more comfortable straying from your current path to try new things.

    5. Muster Your Courage

    Fears and self-doubt may arise when you encounter difficulties and setbacks. Sometimes, they may also come when you’re taking risks. You have to manage these negative emotions well and not allow them to discourage you. Tap into your courage and try doing at least one new thing each week to develop it.

    6. Use Your Support Group

    As stated above, you need to build a strong support group before you even start the process of reinventing yourself. Your group will keep you from taking wrong turns and encourage you when you get too weighed down by problems. Don’t be afraid to call them, or even ask them out for coffee if you need to vent about the current difficulties you’re facing.

    7. Remind Yourself Every Day of Your Commitment

    Write your goals on different-sized cards and scatter them at home and at work in places where you can easily see them. This way, you will constantly be reminded of where you want to be. Remember, writing down your goals helps them stick[1].

    8. Accept Failure, Learn, and Resume Your Journey

    Failing is normal, especially when we’re trying out something new. When you fail, simply recognize it, learn from it, and move on. Failure, in the end, is the best way to learn what does and doesn’t work, and you simply won’t be able to learn how to reinvent yourself if you don’t accept the inevitable failures that await you.

    Final Thoughts

    If you truly want to learn how to reinvent yourself and live the life you desire, take the advice above and start taking action. It will take time, patience, and plenty of effort to make the change you want happen, but it will be all worth it.
