Exercise protects Brain from Stress

Most of us are aware of what happens to the body when we exercise. We build more muscle or more stamina. We feel how daily activities like climbing stairs becomes easier if we exercise regularly. When it comes to our brain and mood though, the connection isn’t so clear.

f 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, is released in your brain. Your endorphins main purpose is to minimize the discomfort of exercise, block the feeling of pain and are even associated with a feeling of euphoria.

So, BDNF and endorphins are the reasons exercise makes us feel so good. The somewhat scary part is that they have a very similar and addictive behavior like morphine, heroine or nicotine. The only difference? Well, it’s actually good for us.

Summing-up: Physical exercise reorganizes the human brain so that it responds better to stress and normal brain function is less likely to be affected by anxiety.
