Have you ever been so stressed that you could not fall asleep the night before a quiz or an exam?I think it happened to all of us at some point in time. It’s always important to have a good night rest before an exam. So what should you do to relax the night before an exam?What is found to be good is to drink a cup of something warm. The best would be some warm milk or a caffeine free tea. Try to avoid hot cocoa since that will give you a sugar rush and might get ou even more nervous. If it’s not too late at night, you can even get a cup of a light soup (ex chicken soup).What all these do is boost your serotonin, a calming brain chemical, and therefore they relax you.For adults: you can have a glass of wine before going to bed and you will sleep more profound that night and get more rest.
