Having a healthy body can help you deal with stress.

• Be active. Physical activity and exercise are great for letting out stress and tension. Make time for some light aerobic activity like walking, using a treadmill, or using stationary bike. Slowly try to do it more often, for longer times, and make it more challenging as your concussion symptoms allow. Exercise is great for letting out stress and tension.
• Eat a healthy diet. Good nutrition helps your body deal with stress, so be mindful of what you eat. Start your day with breakfast to keep your energy up and your mind clear. Eat 3 balanced and nutritious meals throughout the day. Drink lots of water, aiming for 8 glasses each day. Ask your doctor or healthcare provider about vitamins or supplements that may help your symptoms, like vitamin D, vitamin B2, omega 3.
• Limit caffeine and sugar. The "highs" that caffeine and sugar can give often end with a crash in mood and energy. By limiting coffee, pop, chocolate, and sugary snacks, you’ll feel more relaxed and sleep better.
• Don’t use alcohol, tobacco, and other drugs. Alcohol, tobacco, or other drugs may ease your stress for a moment, but it won’t last. They’re bad for your body and your mind and can get in the way of your recovery. Don’t avoid what’s bothering you. Deal with problems directly and with a clear mind.
• Get enough sleep. Sleep fuels your mind and body. Feeling tired will make you feel more stress and make it hard to think clearly.
