Today, students and professionals are using 90/20 study method to increase their productivity. In this technique, work is done by focusing completely for 90 minutes and after that a 20 -minute break is taken. This method is scientifically proven and is based on the natural activity cycles of the brain i.e. Ultradian Ridms.

Ultradian Ridms is the rhythm of the brain in which high and low mental activity periods are repeated throughout the day. Each cycle is about 90 to 120 minutes. During this time the brain works in a high focus position and then a 20 -minute recovery phase comes, which slows down the speed of the brain and reduces fatigue.

Body biological rhythm and performance
The foundation of this method is at the Basic Rest-Activity Cycle, which was told by Nathanial Clatman, a sleepist. This cycle controls our productivity and sleep stages in both day and night. The brain remains more alert and error -free during 90 minutes with high attention, while there is a lack of fatigue and attention during 20 minutes of recovery.

Psychologist Anders Ericson found in a study by top violinists that he used to adopt 90 minutes of practice and then the rest process. In the structure of such work, professionals recorded 40% more productivity and 50% less mental fatigue.

Brake is necessary to control energy
In 90/20 method, important work should be done in high focus times and in a 20 -minute break, the brain and body should be relaxed. During this time, it is beneficial to spend light walk, stretching or spending time in nature. Screen or work related activities should be avoided in breaks.

Recovery signal signs
Taking yawn is the initial warning of mental fatigue. There may be restlessness and instability during low energy. The difficulty in maintaining attention and increasing number of mistakes is also a sign that breaks the brake.

How to adopt 90/20 way
Students and professionals should understand their energy patterns and determine the blocks of work or work. It can be adopted in three steps: first note the pattern of your energy and attention, then keep important tasks in high focus time and finally take a device-free brake so that the mental performance is cured again.
