Exercise can reorganize the brain and boost your willpower

Exercise is not only good for the body, your brain also benefits.

Sure, exercise is good for your body, but what about your brain? Well apparently there’s a link between exercise and mental alertness, in a similar way that happiness and exercise are related.

A lifetime of exercise can result in a sometimes astonishing elevation in cognitive performance, compared with those who are sedentary. Exercisers outperform couch potatoes in tests that measure long-term memory, reasoning, attention, problem-solving, even so-called fluid-intelligence tasks.

Of course, exercise can also make us happier, as we’ve explored before:

If you start exercising, your brain recognizes this as a moment of stress. As your heart pressure increases, the brain thinks you are either fighting the enemy or fleeing from it. To protect yourself and your brain from stress, you release a protein called BDNF (Brain-Derived Neurotrophic Factor). This BDNF has a protective and also reparative element to your memory neurons and acts as a reset switch. That’s why we often feel so at ease and things are clear after exercising and eventually happy.

At the same time, endorphins, another chemical to fight stress, are released in your brain. The main purpose of endorphis is this, writes researcher McGovern:

These endorphins tend to minimize the discomfort of exercise, block the feeling of pain and are even associated with a feeling of euphoria.
