Maybe there is something wrong with your sleep schedule. Must take a nap at noon 1 hour or so. Because of working and studying all morning, my brain will be very tired and I won't rest at noon. If you continue to be tired until the evening, you will definitely be tired and want to sleep at night, exceeding the physiological load of your brain.

I suggest you do more exercise, because exercise can speed up the heartbeat, moderately contract blood vessels, accelerate blood circulation, increase blood supply to the brain, increase the anti-fatigue ability of the brain, and enhance the functions of various tissues and organs in the whole body. This is the most fundamental and effective anti-fatigue method. How long can strong tea and coffee last? Pay attention to eat more foods rich in vitamins (eat more vegetables and fruits), add a little lean meat and eggs, but not too nutritious; Too much nutrition increases blood lipid, too high blood lipid increases blood concentration, too high blood concentration slows down blood flow and reduces cerebral blood flow, causing or aggravating cerebral blood supply deficiency. If you are too tired to read at night, you can wash your face with cold water. If you are in the dormitory or at home, you can jump rope or do push-ups to get rid of sleepiness.

If you rest at noon, have enough time, sleep for 7-8 hours every day and still feel very tired, you should pay attention to the symptoms of insufficient blood supply to the brain. Symptoms of cerebral blood supply deficiency include: frequent dizziness, listlessness, lethargy, memory loss, general weakness, fatigue and so on. Not every patient with cerebral ischemia has all the symptoms of cerebral ischemia. If you have 2-3 symptoms of cerebral blood supply insufficiency, plus blood pressure (low or high) or blood lipid, blood sugar (abnormal) and anemia, plus Doppler examination results (slow blood flow in cerebral arteries), you can make a diagnosis of cerebral blood supply insufficiency.

It is recommended that you go to the hospital to have your blood pressure measured several times (because the problem of insufficient blood supply to the brain is mostly caused by blood pressure, and most young people are caused by hypotension). If the blood pressure is normal, then check the blood lipid, blood sugar and blood routine (excluding anemia), and basically you can make a clear diagnosis. If these tests are normal, then your symptoms such as fatigue are physiological, which may be caused by lack of exercise. That's a relief. We should strengthen our exercise in the future.

I hope the above suggestions will help you. I wish you a speedy recovery!
