3. Exercise before you study (and consistently!)

Exercise has both long and short-term effects on cognition. When you exercise, your body interprets the physical stress as you fighting or fleeing an enemy and activates your sympathetic nervous system. In response, your brain is flooded with extra blood, rich in oxygen and nutrients, to make what it thinks could be life-saving decisions. It’s even been demonstrated that exercise can lead to neurogenesis, or the creation of new brain cells–a process previously thought impossible.
