The Dark Side of Dopamine: How Our Addictions to Social Media and Gaming are Rewiring Our Brains

Do you find it difficult to work on productive tasks, such as studying or building a business, but easy to engage in less beneficial activities like watching TV, playing video games or scrolling through social media? Have you ever wondered why some people are more motivated than others, even when faced with difficult tasks? The answer could lie in a neurotransmitter called dopamine.

What is Dopamine?

Dopamine is often considered a pleasure molecule, but its role goes beyond that. Dopamine drives our desire to achieve something and gives us the motivation to act on it. To understand how powerful dopamine is, researchers conducted experiments on rats where they implanted electrodes in their brains. They stimulated the rat’s reward system whenever the rat pulled a lever. This process led to the rats becoming so obsessed with pressing the lever that they would refuse to eat or sleep. They would only stop when they were exhausted. When researchers blocked the release of dopamine in the brain’s reward center, the rats became so lethargic that they would not move, eat or even mate.

How Dopamine Motivates Us

The role of dopamine goes beyond food and water. It is also an essential factor in determining how motivated we are to carry out tasks. Our brains develop priorities based on the amount of dopamine that is expected. If an activity releases little dopamine, we are not motivated to do it, but if it releases a lot, we are motivated to repeat it. Any activity that has the potential for a reward releases dopamine, making us feel motivated. On the other hand, if we know there are no immediate rewards with the behavior, our brains won’t release dopamine, and we won’t be motivated to do it.

High Dopamine Behaviors

Many behaviors release dopamine, and while some are beneficial, others are harmful. Drinking water when thirsty releases dopamine, but the highest dopamine release happens when you get a reward randomly. Social media, video games, and internet pornography are examples of high dopamine behaviors. These activities release dopamine because we anticipate some sort of reward with each of these behaviors, such as getting a text message or notification. We become like those rats, pressing the lever to get a new dopamine hit. We flood our brains with unnaturally high amounts of dopamine on a daily basis, even if we don’t realize it.

The Danger of High Dopamine Behaviors

Our body’s biological system called homeostasis seeks to maintain balance. When we engage in high dopamine behaviors, it leads to a release of large amounts of dopamine, which our bodies perceive as an imbalance. Our bodies then react by reducing the number of dopamine receptors available, resulting in reduced motivation. Additionally, high dopamine activities are highly addictive, and we may become dependent on them. Therefore, it’s essential to control our engagement with high dopamine behaviors.

Conclusion

Dopamine plays an essential role in motivating us to carry out tasks. Activities that have the potential for a reward release dopamine, and the more dopamine that is released, the more motivated we become. While many behaviors release dopamine, some can be harmful and addictive. To maintain motivation, it’s crucial to control engagement with high dopamine behaviors.
