It is very normal to lose concentration while studying or doing any work. The complaint 'can not be placed in mind' is often heard. There are some easy steps to increase concentration in study. However, it is very important to be self-confident before applying these methods.
1. Keep things that can distract attention before starting work. Considering the importance of work, keep mobile, TV, etc. off. When reading FM radio and computers while reading, attention is disconnected.
2. Some studies have shown that, when listening to light instrumentation in some work or reading, it helps in improving attention. Google will get many instrumental songs that can be used as a way to increase concentration. But the music provided by singers/songwriters will not help you in this regard. Meditation helps in improving attention. 10 minutes before sleeping in the morning and at night, enhances the efficiency of the brain. As a result, the ability to concentrate on any matter gradually increases.
4. The more you keep the brain busy, the greater your ability to work in a constructive way. In this case brain games are very effective (concentration exercises). Chess, sudoku, billiards, crossword puzzles, etc. will increase your thinking ability and increase focus. There are also plenty of brain games for mobile or computer play.
5. Studies have shown that at the time of doing any work, chewing gum chewals have the advantage of paying attention to that work. So you can use chewing gum to increase attention. But keep in mind that sugar must be free.
6. Studies in the University of British Columbia have shown that red color helps improve membrane strength and attention (improved concentration). You can increase the color of the red color in the office or reading table by using a red object, red shirt, red wallpaper on the computer etc.
