Listen to Music
One way of improving your focus is by constantly listening to music. This means really listening and getting to learn and understand the words in the music. This helps to clear your mind by making you focus on only one thing and so helps calm your mind and freshen it by removing those blocks that limit your concentration and focus.
Meditation helps with improving focus and concentration. Some people spend at least one hour a day meditating but starting out with even 10 or 15 minutes can be very beneficial. One way of improving your meditation is through focusing on your breathing. By focusing on the air you breath, the way it touches your nostrils and how it enters your throat and leaves helps in calming your system. This can provide a sense of peace and contentment and helps in improving your focus.
Set Small Achievable Realistic Goals
Setting huge, unrealistic goals can be very frustrating and can mean losing focus. One way of improving focus is to set goals which are smart (simple, measurable, achievable, realistic and time bound). This helps in reducing pressure and a lot of the frustrations that build when goals seem to be forever out of reach. Stress and pressure can make you lose concentration. It is better to set goals which can be achieved in maybe a week or a month and which will ultimately lead to your long term goals.
Studies have shown that regular exercise can calm the mind and improve focus. Exercises such as swimming, going to the gym dancing, gardening, etc help you lay off mental burdens and pressures. Exercise also relaxes the mind and improves concentration and focus. Also one can improve focus by frequently exercising the mind by for example filling crossword puzzles, engaging in social quizzes or puzzling out sudoku games etc this helps in making sure your mind is not idle.
Wear light clothes when you can
Wearing light and loose clothes also helps improve your focus. This is because there is sufficient ventilation in your body and free air can easily flow in and out. This helps in keeping your mind fresh and constantly in focus.
