What is a morning 90-minute work block?

A morning 90-minute work block is a dedicated period in the morning where you focus deeply on essential tasks without any distractions. This method leverages the natural ultradian rhythms of your body, which dictate that your focus and productivity are optimized in these 90-minute intervals. During this focused session, you avoid all possible interruptions, such as internet access and phone use, to maintain high levels of concentration and productivity. This approach is based on the idea that breaking your work into these cycles aligns with your cognitive rhythms, allowing maximum efficiency and performance 1 2.
