Hi, I'm Marty Beene, and I'm here to talk about runner's high. We've all heard it before. I just ran ten miles and got this great runner's high but what actually does that feel like? Have you felt it yet? First let's talk about what a runner's high is. Researchers have done many many studies about what happens in your brain when you are doing something pleasurable like watching a movie, spending time with loved ones or even running. It turns out that in certain physical activities your body produces endorphins which is something that makes you feel good. As you probably already know, running is hard. When you are doing it you get tired and sore which doesn't really sound like that much fun. But if you know you are doing something good for your body, maybe you are enjoying the fresh air, some spectacular views, spending time with friends your brain figures out that this is a good thing. So it starts to create these endorphins and that's what feels good. So what does a runner's high feel like? It may be somewhat different for everyone including how strong the feeling is. There's usually a feeling of happiness and often that the running feels easier at times. I sometimes experience a runner's high when I'm on a particularly challenging run. All of a sudden it feels easier so I'm able to run up a hill much easier than before. Some people feel a runner's high very strongly with a feeling of extreme euphoria like they just won the NBA Title or something even after a run that might seem quite ordinary to the rest of us. A lot of runners joke that they feel great as soon as they stop running. Well that may well be a runner's high because they know that they have just done something well for their bodies and their brain has rewarded them with a nice dose of endorphins.
