Does Exercise Release a Chemical in the Brain?

Chemicals released during exercise can actually improve your mood.

Exercise leads to a release of chemicals in the brain that can have positive cognitive effects, according to findings from Oregon Health and Science University . However, it does not apply to all types of exercise and it does not happen right away.

Effects

During exercise, the brain releases several chemicals including neurotransmitters such as endorphins. Studies have shown that certain neurotransmitters can help ward off depression. Endorphins act as guards that help to block both stress and pain. This leads to a numb, high, or euphoric feeling during or after a workout and can play a part in addiction to exercise.

Types

Unfortunately, not all types of exercise are created equal when it comes to brain activity. The brain chemical effects can be experienced through aerobic exercise only. Aerobic exercises are those that cause deep, heavy breathing. Running, hiking, dancing and interval training are all examples of aerobic exercise.

Time Frame

Endorphins generally are not released until 30 minutes after the start of exercise. Although mood enhancement might happen sooner, those looking to benefit from all the feelings associated with endorphins should plan at least a half-hour workout.
