A dopamine detox does little for your brain chemistry

February 2025

Swearing off social media may well improve your mood, but probably not because it resets your dopamine levels

- DR CHRISTIAN JARRETT

A dopamine detox does little for your brain chemistry

The internet is currently awash with articles, videos and podcasts promising to help you “reset your brain reward system” and rediscover the joy in life’s simple pleasures.” Lowering your current level of stimulation, they claim, will help you not only regain your ability to focus, but also become more productive.

The practice has come to be known as dopamine detoxing and, according to its advocates, the reason so many of us are easily distracted and apathetic is because of the over-availability of short-term rewards. Temptations such as social media, video games, junk food, online shopping, coffee and alcohol have burnt out our brains’ dopamine-based reward systems.

The near-constant buzz of these hits has depleted our dopamine levels, leaving us unable to focus on what matters or appreciate the finer things in life.

The basic idea behind a dopamine detox is to cut out all the quick and easy pleasures in our lives for a certain period of time — some detox programmes suggest starting with a single day, before building up to weeks at a time. This, supposedly, will help bring your dopamine back up to a healthier level.

Dopamine detox proponents are tapping into our collective anxiety that attention spans are shortening amid the constant lure of instant gratification, whether it’s bingeing on Netflix shows or playing games on our phones. As is often the case with these kinds of pop psychology fads, there’s a kernel of truth to the notion, but also a lot of oversimplification and, at times, a cartoon-like interpretation of neuroscience.

ARE PSYCHOPATHS REALLY THAT GOOD AT LYING?

Picture infamous psychopaths from fiction, such as the eerily cold and calculating Patrick Bateman in the film adaptation of American Psycho, and they certainly seem like master deceivers. But what about real-life psychopaths? Research confirms that psychopaths are more inclined to lie to get what they want, and that they typically display a striking fearlessness - as if they have ice running through their veins.

WHY DO WE HAVE TWO OF SOME ORGANS, BUT ONLY ONE OF OTHERS?

The majority of animals on Earth, humans included, are bilaterally symmetrical. It means we can be divided roughly into two mirror-image sides. Evolutionary biologists believe that it has been like that for at least 300 million years, and because life organised this way survived, so did symmetrical design. Hence, two eyes, two ears, two lungs and two kidneys.

THE AARDVARK

In a time when people are being asked to consider eating insects, we should, perhaps, learn a thing or two from the aardvark (Orycteropus afer), Africa’s ant-guzzling gourmand. On an average night, the big-schnozzed mammal devours up to 50,000 of the crunchy critters.
