Dopamine, doomscrolling and disconnection: The hidden mental-health cost of your phone

Shorter attention spans, rising anxiety, emotional exhaustion, and an endless need for “the next hit” — experts say our smartphones are quietly reshaping our mental health in ways we’re only just beginning to understand.

We check our phones hundreds of times a day. We scroll, tap, refresh and reply almost automatically. But beneath these everyday habits lies a growing mental health concern: our devices may be changing not just how we communicate, but how we think, feel and relate to ourselves.

According to chartered psychologist Dr Ravi Gill, the constant stimulation of smartphones and social media is subtly eroding our ability to be fully present.

“I’ve certainly noticed with the increase of devices in social situations, people are eager to get to the point quickly,” she says. “Conversations feel more rushed — like something to complete rather than experience. People are looking for that dopamine hit. It becomes: ‘Get to the point, so I can move on.’”

That shift may seem harmless. But over time, it chips away at the depth of human connection.

The dopamine loop driving anxiety

At the heart of our digital habits is dopamine — the brain chemical linked to reward and motivation. Every notification, like, message and swipe offers a small hit of stimulation, training us to keep checking for more.

The result is a low-level state of restlessness. Instead of feeling calm or satisfied, many of us are stuck anticipating the next thing.

Recovery coach Elizabeth Walker believes this mirrors the patterns seen in addiction.

“Our dopamine baseline gets so high that it’s actually impossible to feel satisfied or content with life as it is,” she says. “We’re getting dopamine so easily without having to really work for it.”

Walker, who works with people recovering from substance use, codependency and digital dependency, says modern technology is rewiring our relationship with reward.

“If I focus on all the bad things in my life, I’m going to have a really bad experience of life,” she says. “If I focus on the news and the headlines, I’m going to be scared. If I focus on what’s actually real in my world, I’m going to be grateful.”

That constant stimulation can fuel anxiety, hypervigilance and emotional fatigue — leaving us mentally “on edge” even when nothing is wrong.

Social media and the comparison trap

Alongside overstimulation comes another issue: comparison. Social media offers a curated version of life, where success, beauty, productivity and happiness are constantly on display. Over time, that can create the feeling that we are falling behind.

“We can no longer just be happy with where we’re at,” Gill says. “It’s always: ‘What’s next?’”

Rather than helping us feel connected, social media can intensify loneliness.

“People go on social media to connect,” she explains. “But when they don’t get the responses they’re seeking, it contributes to those feelings of loneliness. It becomes a cycle.”

She also believes our dependence on constant stimulation makes it harder to tolerate stillness, slowness and genuine intimacy.

“We need to start pursuing happiness as opposed to pleasure,” she says. “Finding our pleasure through healthier activities, such as going for a walk, being of service, having real connection with people.”

That distinction matters. Pleasure offers quick relief. Happiness tends to come from meaning, relationships and emotional grounding.

The rise of digital addiction

For many experts, concerns about smartphones are beginning to resemble concerns once associated mainly with substances like alcohol or drugs. Walker says she is increasingly seeing issues around social media, pornography and online gambling in recovery settings.

“Kids aren’t drinking or drugging as much,” she says, “but try and get their phones out of their hands.”

Unlike substances, however, technology is almost impossible to avoid. “You can’t not have access to technology,” she explains. “It’s almost like treating someone with an eating disorder — you still have to engage with the thing.”

That makes digital dependency uniquely difficult to manage. Phones are tied to work, education, navigation, communication and social life. Even schools increasingly rely on apps and online platforms for organisation and homework, while superficially banning phones in school itself.

Digital detox — but make it realistic

Despite the scale of the problem, both Gill and Walker stress that solutions do not need to be extreme.

“A digital detox would be ideal, but it’s not always realistic,” Gill says. “Start with something manageable — even an hour a day.”

For Walker, the goal is not perfection but awareness. “We need to become devoted to our own wellbeing,” she says.

Sometimes, small behavioural changes can make a significant difference: “Put the phone outside the room. Invest in an old-fashioned alarm clock. Take a book to the toilet instead of your phone.”

She also encourages people to reintroduce slower, more grounding activities into daily life.

“We do need to start cooking meals, taking pleasure in feeding ourselves, connecting with other people,” she says.

Gratitude practices can also help retrain the brain away from constant seeking.

“It’s not just saying, ‘I’m grateful the sky is blue,’” Walker explains. “It’s asking: why does this matter to me? That’s the bit that anchors it.”

Relearning how to switch off

Putting the phone down is only half the battle. The harder part is tolerating what comes next. For many people, silence and stillness now feel uncomfortable. Without distraction, difficult thoughts and emotions often surface.

That is why both experts emphasise self-compassion. “We’re very good at supporting others, but not ourselves,” Gill says. “If a friend came to you with these feelings, what would you say to them?”

Walker agrees that inner dialogue matters profoundly. “If our inner world is speaking to us with compassion, forgiveness and love, we’re going to experience a much nicer quality of life,” she says.

She believes the solution to digital overwhelm is not simply reducing screen time, but rebuilding our relationship with ourselves.

“The world around us isn’t going to slow down,” she says. “So we need to take responsibility for ourselves, rather than wait for it to be done for us.”
