Exercise Benefits The Brain
Any kind of exercise, be it aerobic, walking or Yoga, changes the brain's composition, structure and the way it operates. The changes that happen to the brain:
- Brain waves increase
- Increased sensitivity to surroundings
- The building of neurotransmitters and increased neuro-connections
- De-ageing.
MORE IDEAS FROM THE ARTICLE
The brain's electric impulses change, and the Beta waves increase during and after exercise, putting it in a better, more alert state.
Exercise makes our senses sharper and clearer, and we are more perceptive and have better sensitivity to our surroundings.
After exercise, the brain actually builds neurotransmitters, which are essential to its functioning, and optimal operation.
It also forms more neuron connections, helping us think and work better.
The structural changes in the brain after exercise make it more agile, young and energetic. This is because, after regular exercise, it starts to promote the body's growth cells, providing us with essential nutrients.

Many experts consider exercise to be the closest thing to a miracle drug. Running is one of the simplest ways to exercise. It can lift symptoms of depression and improve your mood. It burns calories, builds strength and improves cardiovascular health.

We can remain in stage 4 - similar to a coma or brain death - for only about 30 minutes before the brain wakes up and falls back to sleep again.
Even healthy sleepers wake several times a night, but might not be aware of it.
