What is the Pomodoro Technique?

Set a timer for 25 minutes, and work. Then, take a break for 5 minutes. Then do it all over again. That, in a nutshell, is the Pomodoro Technique (PT).

I’m pretty into productivity tools, but when I first read about PT, I thought it sounded too simplistic. I didn’t understand the point of working for exactly 25 minutes. And why was the break necessary?
