Improving your sleep will improve your SAT score.
One thing you can do to improve your sleep is to exercise.
Exercise will not only make you tired by the end of the day, but it also increases adenosine, the neurochemical that builds sleep pressure throughout the day.
Don’t take this to an extreme though. Too much exercise can increase cortisol levels and actually disrupt sleep. Exercising too close to bedtime can also disrupt sleep by overstimulating you when you should ideally be relaxed before bed.
Apart from helping you sleep, the increased blood flow also helps with thinking and learning!
