Running + heat = sweat

Sweat = fluid + salt

It doesn’t take a rocket scientist to realize that you sweat more in the summer. But sometimes, when we’re out running in these hotter months, we don’t pay attention to what’s going on with our hydration like we should. Maybe we’re so used to drinking a certain amount of water and electrolytes from the winter and spring, that the idea of modifying the perfect balance we’ve grown accustomed to seems absurd. The problem is, when the weather changes, so does the way your body responds to the heat. Sweating is our natural means of cooling our core temperature. However, sweating causes us to lose fluid and salts. Adding more water may not be enough. You may need to increase your electrolytes, as well. Experiment with what works for you and don’t forget to look out for signs of danger. Hydration is not a matter to be taken lightly. Too much or too little can become dangers, even fatal.
