Have you ever noticed how a quick jog or a session of stretching can instantly lift your spirits? This isn’t just coincidence; it’s firmly rooted in science. When we engage in physical activity, our bodies release a cocktail of chemicals, including endorphins, which are fundamental to this feel-good phenomenon. These initial happy hormones play a crucial role, but the benefits of exercise extend far beyond, influencing long-term happiness through various physiological pathways.
