How can we keep enough sleep? I am a junior two student. Go to bed at night 10.00 and get up at 5 am. How to wake me up?

If you want to get enough sleep, try not to read or read less books before going to bed, so that your brain won't get excited and lose sleep. Be sure to take a nap for an hour every day, so as to keep enough energy and focus in class. Regularize your life. It's not too late to go to bed at night 10, and I can't sleep without eating too much delicious dinner. It is also necessary to exercise properly before going to bed, soak your feet in hot water, and persist for a long time to be effective. Relax, be optimistic and have a good rest, and your mind will naturally clear up. Wish you success!
