7 Hydration and Cooling Tips for EMS Pros

A few days ago I wrote a long article about hydration for operational athletes. Working as a paramedic,  firefighter or police officer places unusually demands on your body and fitness. It is important to learn to listen to your body and appropriately feed and fuel before, during, and after operations.

1. Thirst is the best indicator you need water.

2. Water, too which we are highly evolved to need and utilize, is the best liquid to drink.

3. Sports drinks are over-hyped and over-marketed with no evidence they are effective.

4. A well balanced diet generally contains all the nutrients and electrolytes we need. Supplements, like sports drinks, are over-hyped and over-marketed with no evidence they are effective.

5. Regularly hydrate, based on thirst, rather than pre-hydrating for a specific planned or unplanned event.

6. Listen to your body – trying to press onward through hyperthermia and dehydration puts you and others at risk.

7. When you need to lose heat use all available means – radiation, convection, conduction, and evaporation.

    One of the best ways I have found to cool down didn’t come from any medical schooling.  It came from a JuJitsu professor in the good ol’ South.  Take a single ice cube and rub it around the radial artery until the ice melts completely, and yes, the spot will be numb for a while when you are done.  You can also do this to the soft spot behind the knee.  He also said not to use the carotid artery.  So I looked deeper into the physiology and discovered that it works best because it is peripheral, not central.  When you use the carotid, it sends a definitive signal to the brain that says you are too cool and makes you shiver, so you create more body heat… the very thing you are trying to reduce.  Applying the ice peripherally over an artery cools the blood quickly (but not too quickly) with a large volume of blood passing by that spot, then warming slightly as it makes its way through the veins and back to the core, where a very gradual cooling can take place on the core organs, without overexciting those neat little receptors that tell your body you are getting hypothermic.  I (me, myself, without any scientific studies) have found this to be more effective (again, anecdotally) than cold packs and wet towels on the forehead and a fan blowing on you.

    I still think the best way to avoid treating hyperthermia is to not get overheated in the first place.  So stay indoors with the A/C on, don’t live in hot and humid areas, hydrate according to your physician’s advice, and for goodness sake, don’t exercise as much as Greg! ;-)

      Peripheral cooling seems to be part of the sales pitch for rehab products that have firefighters soak their forearms and hands in a cool water bath. Glad it works for you anecdotaly. I think there might be a placebo affect at work as the heat transfer is insignificant.

      Got have the exercise. There is some acclimation possible to heat.
