If the carrier is 200 Hz and the pulse frequency is 14 Hz, the brain hears a &ldquo;tap-tap-tap&rdquo; 14 times per second over that background tone.</p> <p>What&rsquo;s interesting isn&rsquo;t the sound itself, but what happens in the brain. When you listen to a steady rhythmic pulse at a very stable frequency, cortical brainwaves tend to <strong>partially synchronise with that pulse</strong> — a well-documented phenomenon known as <em>frequency following response</em>. It&rsquo;s the same reason listening to music at a specific BPM helps you run to that rhythm.</p> /en/posts/free-online-pomodoro/ Thu, 28 May 2026 00:01:00 +0300 /en/posts/free-online-pomodoro/ <h2 id="what-the-pomodoro-technique-is">What the Pomodoro technique is</h2> <p>The Pomodoro technique was invented by Francesco Cirillo in the late 1980s to help himself study. The name comes from the tomato-shaped kitchen timer he used. The idea is brutally simple: <strong>you work with total focus for 25 minutes, rest 5, and repeat</strong>. After every four cycles you take a longer break of 15 to 30 minutes.</p> <p>Those 25 minutes are the atomic unit of work. One <em>pomodoro</em>. Inside it, no email, no phone face up, no &ldquo;I&rsquo;ll just check one quick thing&rdquo;. And when the timer rings, you really rest. You stand up, look out of the window, walk. You don&rsquo;t open another tab.</p>
