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.

    10 Things Happy People Do Differently

    10 Things Happy People Do Differently

    Think being happy is something that happens as a result of luck, circumstance, having money, etc.? Think again.

    Happiness is a mindset. And if you’re looking to improve your ability to find happiness, then check out these 10 things happy people do differently.

    Happiness is not something ready made. It comes from your own actions. -Dalai Lama

    1. Happy people find balance in their lives.

    Folks who are happy have this in common: they’re content with what they have, and don’t waste a whole lot of time worrying and stressing over things they don’t. Unhappy people do the opposite: they spend too much time thinking about what they don’t have. Happy people lead balanced lives. This means they make time for all the things that are important to them, whether it’s family, friends, career, health, religion, etc.

    2. Happy people abide by the golden rule.

    You know that saying you heard when you were a kid, “Do unto others as you would have them do to you.” Well, happy people truly embody this principle. They treat others with respect. They’re sensitive to the thoughts and feelings of other people. They’re compassionate. And they get treated this way (most of the time) in return.

    3. Happy people don’t sweat the small stuff.

    One of the biggest things happy people do differently compared to unhappy people is they let stuff go. Bad things happen to good people sometimes. Happy people realize this, are able to take things in stride, and move on. Unhappy people tend to dwell on minor inconveniences and issues, which can perpetuate feelings of sadness, guilt, resentment, greed, and anger.

    4. Happy people take responsibility for their actions.

    Happy people aren’t perfect, and they’re well aware of that. When they screw up, they admit it. They recognize their faults and work to improve on them. Unhappy people tend to blame others and always find an excuse why things aren’t going their way. Happy people, on the other hand, live by the mantra:

    “There are two types of people in the world: those that do and those that make excuses why they don’t.”

    5. Happy people surround themselves with other happy people.

      One defining characteristic of happy people is they tend to hang out with other happy people. Misery loves company, and unhappy people gravitate toward others who share their negative sentiments. If you’re struggling with a bout of sadness, depression, worry, or anger, spend more time with your happiest friends or family members. Chances are, you’ll find that their positive attitude rubs off on you.

      6. Happy people are honest with themselves and others.

      People who are happy often exhibit the virtues of honesty and trustworthiness. They would rather give you candid feedback, even when the truth hurts, and they expect the same in return. Happy people respect people who give them an honest opinion.

      7. Happy people show signs of happiness.

      smile

        This one may sound obvious but it’s a key differentiator between happy and unhappy people. Think about your happiest friends. Chances are, the mental image you form is of them smiling, laughing, and appearing genuinely happy. On the flip side, those who aren’t happy tend to look the part. Their posture may be slouched and you may perceive a lack of confidence.

        8. Happy people are passionate.

        Another thing happy people have in common is their ability to find their passions in life and pursue those passions to the fullest. Happy people have found what they’re looking for, and they spend their time doing what they love.

        9. Happy people see challenges as opportunities.

        Folks who are happy accept challenges and use them as opportunities to learn and grow. They turn negatives into positives and make the best out of seemingly bad situations. They don’t dwell on things that are out of their control; rather, they seek solutions and creative ways of overcoming obstacles.

        10. Happy people live in the present.

        While unhappy people tend to dwell on the past and worry about the future, happy people live in the moment. They are grateful for “the now” and focus their efforts on living life to the fullest in the present. Their philosophy is:

        There’s a reason it’s called “the present.” Because life is a gift.

        So if you’d like to bring a little more happiness into your life, think about the 10 principles above and how you can use them to make yourself better.
