Allow yourself to rest
Research tells us that while the brain represents just two percent of a person’s total body weight, it accounts for 20 percent of the body’s energy use — and that’s under normal circumstances. While training, you’re going to feel more mentally tired than normal. That’s healthy and expected. Remember, your brain is working, changing, and growing. Whenever you can, let yourself take a mental and physical break or a nap. If possible, try not to do overly mentally taxing activities on the days you train.
Feed your brain well
Supporting your brain with high quality nutrition will help training be more successful. What you eat directly impacts what goes on in your brain. A brain-healthy diet can improve your energy, mood, and focus throughout the day and ensure that your brain has the fuel it needs to make beneficial changes. An intelligent diet full of good-for-you brain food would include lots of protein, fish, complex carbohydrates, leafy greens, vegetables, fruits, and healthy fats.
Your brain is 20 percent water. Staying hydrated is important for brain health because the brain does not store water. The only way to replenish it is to drink more.
Avoid caffeine before training
We love our coffee too! But that daily dose of caffeine won’t help your brain in neurofeedback training. When you drink coffee or a caffeinated beverage before training, your brain is already functioning at a higher than normal speed, making it more challenging to train. This doesn’t mean you can’t train your brain; it just means you’re more likely to feel anxious during your session and that day may not be as effective as it could be.
It would be ideal if you could come to each session with a brain that’s not caffeinated. Also, it’s best not to drink alcohol or use marijuana or other substances for 24-hours prior to training. For optimal results, you will want to refrain from vaping or smoking one hour prior to training. All of it affects your brain activity.
