The bottom line is that no one is immune to the effects of weather during a run. Stay cool by sticking some ice cubes under your hat or even in your shorts or sports bra. If you still have to get a harder run in, try running early in the day and avoid the sun as much as you can by picking a shaded route. At the end of the run, you’ll gain satisfaction knowing you did your best. Keep an eye on your heart rate and other stress indicators. While mental math is unavoidable on the run, switching your focus from distance to time will keep you from comparing your regular paces to your heat-adjusted ones. One suggestion is to focus on your total run time rather than the distance or pace. Instead, focus on the elements you can control, like hydrating properly, dressing appropriately, and changing your mindset. While you can adjust your race goals on a sultry summer day- you know, the ones where you walk out the door and a film of moisture instantly develops on your skin- don’t let it get in your head. The good news is that it’s not common to come across both high elevation and high dew point, since higher elevation means decreased barometric pressure, which decreases dew point. In effect, a high dew point might as well be a jaunt in the Rocky Mountains, but without the cool weather and beautiful trails. Both high elevation and high saturation lower the density of oxygen in the air, making it feel harder to breathe. You may have heard how tough it is to run at high altitude, and running in a high dew point poses a similar challenge. Therefore, dew point doesn’t just affect the body’s attempt to self-regulate its temperature through sweat, it also affects the amount of oxygen you get in each breath. The higher the dew point is, the more saturated the air is with water. In technical terms, dew point represents the temperature when air, at a given atmospheric pressure, reaches saturation point and can no longer hold onto moisture. But in many regions, high heat comes with a high dew point, meaning the air is already so filled with water, it’s difficult for sweat to evaporate off your skin.
#DEW POINT VS HUMIDITY SKIN#
It’s the body’s natural mechanism for cooling off, and if you combine that moisture on the skin with a nice breeze, life can be pretty good. Most runners are familiar-or rather, overly familiar-with the concept of sweat.
