Excessive study and headache are caused by long-term nervous tension. At this time, the first thing to do is to give up studying, let your nerves get a full rest, and then eat some nerve-soothing food, such as nutritious walnuts. Walnut has a certain sedative effect on brain fatigue, but it can't cure headache.

Food containing protein can also be eaten. If you can't relieve your headache, you should take some tranquilizing brain tonic. If you use your brain too much, you must supplement your nutrition. Eat more foods that help nourish nerves, such as fresh shrimp, fish and lean meat. Protein in these things can not only ease your nerves, but also enhance your physique. I suggest you eat more.
