"How can I study for long hours without getting tired?

Taking breaks while you study is really important. Try to get up at least once an hour to stretch your legs or take a short walk. Make sure you take breaks for meals and have a light snack if you get hungry between mealtimes. Drinking water will also help boost your energy. If you get really tired, put your head down for a 15-minute nap. It also helps to get a good night’s sleep before your study session."
