Last evening, a client messaged me at 21:47 to apologise for missing my earlier message. He had been at his daughter’s birthday dinner. He was apologising for being at a birthday dinner. That same weekend, I read a dossier in Le Défi Media that explained exactly why he felt he had to.
We used to give people our phone number. Now we give them our attention, on demand, at any hour, and we call it professionalism. Digital boundaries have quietly become one of the hardest conversations in modern life, because being reachable is no longer treated as a courtesy but as a duty. A message left on “seen” feels like a small betrayal. A reply delayed until morning feels like a career risk. This article is about how that happened to us, what it is doing to our nervous system, and how to take our attention back without setting our relationships on fire.
What a Mauritian psychologist just named for all of us
Le Défi Media published a piece on 16 August 2026 that deserves a wider audience. In it, clinical psychologist Dr Anjum Heera Durgahee describes how hyperconnection has transformed availability into an expectation of response. A phone number was once something we gave mainly to loved ones; now we hand it to schools, shops, delivery services, and strangers we will never meet again, and through repetition the gesture has stopped feeling like an opening into our lives. She names the mechanism habituation: when an action repeats without an immediate negative consequence, it starts to feel normal, and therefore safe. Meanwhile, WhatsApp’s “seen”, “online”, and typing indicators do not merely confirm delivery; they broadcast presence, so the possibility of replying has hardened into the expectation of replying. And notifications keep the brain in a state of alert, feeding stress, emotional fatigue, and anxiety over time.
Her most important line is eight words long: “Boundaries are not barriers. They are protection strategies.”
Read that again slowly. Most of us have spent years believing the opposite, that a boundary is a wall we build against people. It is not. It is a roof we build over our own attention.
The neuroscience of a mind that never clocks off
Here is what is actually happening in your body when your phone sits face up on the dinner table.
Your brain runs a threat-and-opportunity scanner that predates smartphones by a few hundred thousand years. Every ping recruits it. Researchers call the resulting state telepressure, the felt urge to respond quickly to messages, and it is associated with poorer sleep, higher exhaustion, and more burnout symptoms. The problem is not only the interruptions you answer. It is the anticipation of interruption, a low hum of vigilance that never fully switches off. Physiologists have a term for the cost of staying permanently ready: allostatic load, the slow wear and tear on a body that is always braced for the next demand.
There is a dopamine story here too. Messages arrive on a variable schedule, sometimes rewarding, sometimes not, which is precisely the pattern that makes slot machines compulsive. And in Neuro-Linguistic Programming we would add the concept of an anchor: a stimulus that has been paired with a state so often that it now triggers the state automatically. For many of us, the WhatsApp tone is an anchor for mild alarm. We did not choose that association. We rehearsed it into existence, one notification at a time.
None of this makes you weak. It makes you a well-functioning human nervous system responding exactly as designed to an environment that was not designed for you.
The availability debt
Let me give this phenomenon a name, because naming it is half of dissolving it. I call it the availability debt: the unspoken balance of instant replies you now owe, simply because you have always paid before.
Every time you answered within minutes, you made a small deposit into other people’s expectations. Years of deposits have compounded. Now the debt collector is your own conscience: the guilt you feel at 22:00 over a message that could comfortably wait until 09:00. Notice something crucial here. Nobody formally imposed this on you. As Dr Anjum observes, we often reply not because the sender demands it but because we fear seeming impolite, unprofessional, or disappointing. The availability debt is largely self-issued. Which is quietly good news, because what you issued, you can restructure.
Your attention is the only currency you spend in every single transaction of your life. Guard it like your reputation, because increasingly, it is your reputation. Reachable is what your phone is. Present is what you are.
Availability is not presence
This is where the leadership conversation begins. I have coached executives who answer every message within four minutes and whose teams still describe them as absent. Speed of reply is not quality of attention. A leader who is half-listening in every meeting because a device is vibrating against their thigh is teaching the whole organisation that fragmented attention is the standard. Digital boundaries, in that sense, are not a wellness perk. They are self-leadership made visible. The way you manage your own attention is the loudest lesson you ever give about how others should manage theirs, at work and at home, where creating balance begins with the same discipline.
Sit with these three questions for a moment. When did you last leave a message unanswered overnight without explaining yourself? Whose disappointment are you actually managing when you reply at 21:00, theirs or your imagined version of theirs? And if your phone could speak, would it describe you as its owner or its employee?
Repaying the debt on your own terms
Renegotiating the availability debt does not require a dramatic announcement or a digital detox retreat. It requires small, repeated, visible acts of delay. Separate professional and personal channels so one glance does not expose you to your entire life. Switch off read receipts, or at least stop treating “seen” as a promise. Choose one protected window each day, perhaps the first hour after waking, and let messages age in it. And when a reply genuinely can wait, let it wait once, on purpose, and observe that the world does not end. Each unpunished delay retrains both your habituation and everyone else’s expectations. This is harder for senior leaders, whose roles blur every line, which is exactly why executive coaching so often starts with the phone rather than the strategy.
There is also a wider Mauritian question hiding in this story. A society that is finally breaking the silence around mental health cannot at the same time treat rest as rudeness. If we admire the colleague who replies at midnight, we are subsidising the very exhaustion we claim to be worried about.
The last word
Your phone will be charged again tomorrow morning. The real question is whether you will be. Digital boundaries are not about caring less; they are about choosing when your care arrives, so that it arrives whole. Start repaying the availability debt this week, one delayed reply at a time.
And if you would like a thinking partner while you redraw those lines, I offer a free fifteen-minute consultation. Bring your phone. We will talk about who owns whom.
