From Running Magazine:
Recently I was in Niagara Falls, Ont. for several days and reveled in the opportunity to run alongside the iconic waterfall. It’s truly an invigorating experience to be in the presence of such a natural wonder.
The day I went running was overcast, cool and extremely foggy, but it didn’t matter. It’s well known that Niagara Falls is a region that generates one of the highest amounts of negative ions in the world, due to the rushing water. Negative ions are said to create a feeling of mental well-being and increase concentration– benefits which I knew could definitely enhance the running experience. I was looking forward to seeing if running beside the Falls had this effect on me. I can say I definitely experienced all of these feelings after running on this particular day.
