Even without social media, our phones have a subtle, damaging effect on mental health. The constant ping of notifications and the pressure to reply instantly are pushing our minds to the limit.
The Shift from Office Hours to Constant Communication
When Devi Sridhar first started teaching at Oxford in 2005, she offered office hours a couple of times a week for students to chat in person. Emails were formal and rare. Fast forward to 2026, and office hours have been replaced by incessant email and Teams messages, with responses expected within hours or minutes, blurring the line between work and personal time.
Every time a notification pops up, Sridhar feels her stress levels rising. Modern communication pushes us into an 'always on' state, generating feelings of exclusion or rejection.
How Digital Messaging Strips Away Nuance
Human brains evolved for face-to-face communication within small groups of no more than 150 individuals. Social interaction used to include facial expressions, vocal tone, eye contact, and body language. Modern text-based messaging removes these cues, leading to misinterpretation and increased stress.
A 2022 study in Boston found that days with more text messaging were linked to greater stress and negative feelings, while in-person contact was associated with positivity. A 2026 review confirmed that wellbeing is higher with in-person interaction than screen-based communication.
The Stress of Read Receipts and Ghosting
Features like read receipts and typing indicators have added new sources of stress. Delayed or ignored messages can activate brain regions associated with physical pain, known as social pain. Ghosting—abruptly ending communication without explanation—triggers biological alarm systems, raising stress levels, heart rate, and blood pressure.
Even short periods of being left 'on read' can cause micro-rejection, especially for those with low self-esteem. Meanwhile, those who feel pressured to reply quickly experience constant pressure to be present, even when they don't want to engage.
Cognitive Fatigue and Emotional Exhaustion
Every notification represents a small decision: respond now, later, or ignore? Multiplied by dozens of times a day, this leads to cognitive fatigue and emotional exhaustion. Studies show high rates of burnout, exhaustion, and loneliness globally. We are more connected than ever, yet more lonely and stressed.
Our nervous systems were designed for immediate, tangible threats, not for the constant pinging in our pockets or the stress of being left unread.
