Hello doctor, I am a 19-year-old girl, weight 38 kg, height 5 feet. So my problem is related to brain concentration. Earlier up to school, I had good concentrating power. After schooling, I started preparing for entrance exams and it has been two years preparing for the same but now I feel that I have trouble concentrating over questions, concepts during class or while doing self-study. Please help.
Hi. Lack of concentration can be due to several reasons, most common reasons are stress, lack of sleep, disinterests in the project and lack of motivation. Here are some tips and the principle by which they help you. Minimum seven hours sleep helps to reinforce the memory, and re-energize you for the next day. Regular routine, especially sleep timings, starting from your meal times, the time you visit the library, and workouts, keep it regular. Improves your time management, keeps you healthy and prevents loss of time due to sickness. Eat healthy. Eat what suits your taste and digestive capacity. Eat from only hygienic places. Again this helps prevent the unnecessary sick leaves. Non-study activities. It is a must, it gives a break to your mind which is already stressed by continuous and monotonous study hours. It could be anything starting from prayer, meditation, sports activity, work outs, morning or evening jogs. Have a healthy study group. Do not be selfish with your group, be contributory towards your group. It has multiple benefits, it acts like a mnemonic helping you remember facts in relation to place our person you discussed it with. It gives a sense of easiness to find many people are with you on the same boat. It acts as a strong motivation, if there is a healthy and friendly competition among the group members.  Stay away from distractions like the internet. Keep distance from people who speak negative most of the time. Try to be in company of people who are highly charged in energy. All the best.
