Why do I lose focus after 30 minutes and how can I extend that time?

Your mind has an actual metabolic rhythm — it's not laziness or weakness. Patanjali described the mind as having natural cycles of engagement and rest. After 20-40 minutes, depending on the person and task, your prefrontal cortex (the focus center) needs recovery. Fighting this is like asking your muscles to lift weight indefinitely without rest. The solution isn't to push harder; it's to respect the cycle. Try this: work in focused 25-30 minute blocks, then take a real break — not scrolling, but movement, stillness, or conversation. After 3-4 of these blocks, take a longer 15-20 minute break. Over weeks, your focus duration naturally extends because you're not depleting yourself. The key variable is actually sleep. I know you've heard this, but your ability to sustain attention drops 30% with poor sleep. That's neuroscience, not motivation. Start there before anything else. One more thing: what you're focusing on matters. If you're genuinely interested, you'll go longer automatically. If you're forcing it, 30 minutes might be your honest limit — and that's information worth honoring.
