Endorphins are endogenous opioid neuropeptides and peptide hormones in humans and other animals. They are produced and stored in the pituitary gland. The classification of molecules as endorphins is based on their pharmacological activity, as opposed to a specific chemical formulation
Serotonin is a chemical that has a wide variety of functions in the human body. It is sometimes called the happy chemical, because it contributes to well being and happiness. The scientific name for serotonin is 5-hydroxytryptamine, or 5-HT. It is mainly found in the brain, bowels, and blood platelets
Both of these chemicals I like to manufacture and experience their wonderful benefits: nice calm mood and relaxed body. Just what I'd call a positive state of being. It helps me not sweat the small stuff and even tolerate rainy days a lot better. Would you like to experience this too? Easy just get into a regular exercise program and you will. Best way to get "high on your own supply" not break any laws and do right by your body and mind. My exercises of choice: brisk walking, jogging and bicycling-all 3 together is becoming a regular thing for me.
