What is the role of endorphins released during exercise?

Endorphins play a significant role in the body's response to exercise by helping to relieve pain and inducing feelings of happiness or euphoria, often referred to as the "runner's high." These neurotransmitters are released during physical activity and interact with the receptors in the brain to reduce the perception of pain. This helps create a sense of well-being and can improve mood, making exercise not just a physical endeavor but also a mental and emotional boost.

The release of endorphins can promote a positive feedback loop, encouraging individuals to continue engaging in physical activity, as they associate exercise with feelings of happiness and reduced stress. This mechanism highlights the importance of endorphins in exercise, supporting both mental health and the overall enjoyment of physical fitness.
