When we exercise our body “feels” stress and it releases endorphins in response to brain chemicals or neurotransmitters. Endorphins are secreted from our brains, spinal columns and other parts of our body and reduce pain. Endorphins also trigger a positive or euphoric feeling in our bodies by binding to our neuron receptors, just as some pain medicines do. This positive feeling is similar to morphine but, without its’ addiction or dependence. This positive feeling is often described as a “runners high” or a “second wind”.
Physical activity improves our self-esteem, reduces stress and anxiety while fighting off depression and improves our sleep. Keep all this in mind the next time you are debating on whether or not to get your workout in and get in the gym! Remember, the hardest part of a workout is getting started.
