Should you work out in the heat?

Screen Shot 2016-06-21 at 6.11.18 AMThe weather news out of the southwest over the past few days has been positively historic.

On Sunday, Phoenix topped out at 118 F, the fifth highest temperature ever recorded in the city. Blythe, California, set an all-time record high of 124 F on Monday. And these are only a couple of the record-shattering highs that have been popping up all over the region. In Southern California, The National Weather Service reported 17 daily heat records on Sunday alone.

So what do you do when you’re a dedicated runner/cyclist/hiker/outdoor enthusiast, and it’s hot enough to bend railroad tracks? Or melt the tarmac enough to cause a plane to sink? And I’m not exaggerating: Both of these actually happened during previous heat waves.

Heat is nothing to mess around with. According to federal data, it actually causes more deaths annually in the United States — about 130 — than flooding, lightning, tornadoes, hurricanes or cold. In fact, Phoenix fire officials blamed the severe heat for the deaths of four hikers over the weekend,

I don’t mind summer, but these temperatures are crazy. Once it reaches the 80’s, I’ve pretty much had it. And with yesterday the first official day of the season, there’s no doubt we’ll be seeing a lot more really high temps in the next few months.

So what should you do when it’s really, really hot? Should you go outside and work out?  Or should you skip it entirely and feel like a complete slug?

You could sit around and dream about ski season. That’s one alternative, though it won’t do you much good. Or you could work out indoors, where it’s air conditioned, which is probably a lot better. But if you simply have to get outside, make sure to take the  proper precautions:

  • Drink plenty of fluids. And I mean plenty. Dehydration can contribute to fatigue and poor performance. Even worse, it can cause heat stroke. So be sure to drink 2 cups of water 2 hours before you start your exercise routine, and keep it coming — about 8 ounces every 15 minutes.
  • Wear appropriate clothing, preferably light in color and moisture wicking. Cotton stays wet, making clothes cold and uncomfortable, so it’s not the best choice. There are a lot of high tech fabrics that are much better and will keep you feeling better.
  • Exercise during a cooler part of the day. It’s best to go out first thing in the morning, or late in the day, when the sun isn’t directly overhead.
  • If you stop sweating, stop exercising. Or if you feel nauseous or dizzy or especially hot. This is extremely important. You could be suffering from heat stroke, which can require emergency treatment.
  • Swim. This is a great way to exercise and stay cool at the same time. Kind of a no-brainer, don’t you think?

Also, it’d be a good idea to learn to recognize the signs of heat exhaustion and heat stroke. Here’s a handy-dandy graphic put out by the National Weather Service that can help:

Keep cool, everyone.  Remember, the earth is turning and winter is coming. Then we’ll complain about the cold. 😉

    Yeah, don’t mess around with either heat stroke or exhaustion. Wearing a hat to protect the head is a good idea too.
