Dose of Reality

You open the app. You scroll for two minutes. You put the phone down feeling vaguely worse than when you picked it up. You pick it up again three minutes later. This is not a character flaw. It is the product working exactly as designed. And the gap between how social media makes us feel and why we keep using it anyway is one of the most interesting and consequential questions in modern public health. I want to talk about what the science actually shows — because the honest picture is more nuanced than either "social media is destroying mental health" or "social media is fine, stop blaming technology." The Scale of Where We Are Social media platforms had over 5.17 billion users globally in 2024 with projections reaching 6.05 billion users by 2028. NHS Confederation Source: PMC, MDPI This is not a niche behaviour. It is the dominant communication and information infrastructure of the modern world. Understanding its effects on mental health is not optional for...

 When most people think about addiction, they think about willpower. They think about choices. They think about someone who simply cannot stop doing something they know is bad for them and draw a conclusion about character. This framing is not just wrong. It is actively harmful — because it replaces a biological understanding of a medical condition with a moral judgement that prevents people from seeking help. Addiction is a brain disease. Not a metaphor, not an excuse, not a softening of language for the sake of sensitivity. A literal, measurable, physiological alteration of brain structure and function. Let me show you the neuroscience. How the Brain's Reward System is Supposed to Work To understand addiction, you first need to understand what the brain's reward system is designed to do. The brain's reward system is a network of structures that reinforce behaviours necessary for survival — including eating, reproduction, and social interactions. Central to this syst...

Everyone talks about the big move. The flight. The new chapter. The opportunity. The excitement. Social media is full of people standing in airports with luggage, smiling into the camera, captioning it "new beginnings." Nobody talks about what happens after the airport. Nobody talks about the week you spend figuring out how to open a bank account in a country where you have no credit history, no proof of address, and no idea which documents you actually need until you show up and are told you are missing something. Nobody talks about standing in a queue in a government office, surrounded by a language you technically speak fluently, but in an accent and pace that still makes your brain work twice as hard to process. Nobody talks about the exhaustion of doing ordinary things in a completely unfamiliar system for the first time. I moved to a new country. Not as a tourist. Not for a holiday. Permanently or at least, with the intention of building something permanent. And I w...

Everyone tells you to "manage your stress." Almost nobody tells you how — with actual evidence behind it. Stress is not a mindset problem. It is a physiological response involving specific hormones, specific brain structures, and specific biological pathways. Which means reducing it effectively requires interventions that target those pathways — not just thinking positively or taking a hot bath. Here is what the science actually says works, measured by real biological markers, not just how people report feeling. What Stress Actually Does to Your Body When you encounter a stressor — a work deadline, a difficult conversation, a financial worry — your body activates the hypothalamic-pituitary-adrenal (HPA) axis. This releases cortisol and adrenaline, preparing you for a threat. In short bursts, this is useful. The problem is that modern stressors are chronic, not acute. Work pressure, financial anxiety, relationship tension — these keep the stress response activated for hours, d...

 Protein is the most talked-about macronutrient in fitness culture. It is also the most misunderstood. Half the people you know are obsessing over protein shakes and hitting arbitrary targets. The other half are eating nowhere near enough and wondering why they are always tired, losing muscle, and struggling to recover from exercise. Here is what the science actually says — as of 2025 — and what it means for you specifically. What Protein Actually Does Protein is not just a muscle-building supplement. It is the structural material of your entire body. Your muscles, skin, hair, nails, enzymes, hormones, antibodies, and the haemoglobin carrying oxygen in your blood — all protein. Every time a cell in your body dies and is replaced, protein is the raw material for the replacement. Every immune response requires protein. Every chemical reaction in your body is catalysed by enzymes made of protein. You are not supplementing with protein. You are feeding the machinery that runs yo...
