Avoid Stress in your Final Exams
Remember to breathe
Setting aside a couple of minutes every day to practice mindfulness techniques, such as breathing exercises or UCL's 10 Minute Mind, helps you to calm down your body's stress response and shift your attention back to the present moment. In turn, this gives you time to rationally think through the anxieties you have, rid yourself of unhelpful thought patterns and enables you to deal with a large number of exams and begin more effective revision.
Eat, sleep and exercise well
Pulling all-nighters, surviving on a poor diet, and getting minimal amounts of movement into your day can increase symptoms of anxiety. For your body's best performance, make sure you're getting 8/9 hours of sleep, enough slow-release carbs, less caffeine and more water, and at least half an hour of exercise per day.
