The "runner's high" is a euphoric sensation that some people experience during or after intense exercise, often characterized by feelings of pleasure, reduced anxiety, and a sense of well-being. https://www.realmuscleforum.com/content/choose-which-muscles-to-exercise/ Here's what we know about it: Endorphins and Beyond: While often attributed to the release of endorphins ("endorphin rush"), recent research suggests that other neurochemicals, particularly endocannabinoids, may play a more significant role. Endocannabinoids: These are naturally produced compounds in the body that interact with the same receptors as THC in cannabis. They can produce feelings of relaxation, euphoria, and pain relief. Factors that May Contribute: Intensity and Duration: A runner's high is more likely to occur during prolonged or intense exercise. Individual Variability: Not everyone experiences a runner's high. Factors like genetics, fitness level, and individual sensitivity to these neurochemicals likely play a role. Research: Research on the runner's high is ongoing. Scientists are still investigating the exact mechanisms and the role of different neurotransmitters in this phenomenon. Let's get RUNNING!! (or any other kind of exercise)
