Staying Cool: Lessons From Roy Halladay

PHILADELPHIA (CBS) - I'm a big Phillies fan and certainly a big fan of Roy Halladay -- who isn't? But it is very important that we learn a lesson from Roy.  The lesson isn't how to throw a splitter or how to get people out. It's what can happen to anyone -- even someone in great condition -- if you go out in the hot temperatures and you are not hydrated.

Think about it: Roy Halladay probably had trainers and other people helping him out, so he was in a great situation, but he still ran into difficulties (see related story). That's because heat exhaustion can happen fast.

First of all, it might start with cool moist skin with goose bumps in the heat. You can also experience heavy sweating, faintness, dizziness and fatigue. Eventually you can get a weak rapid pulse, low blood pressure, muscle cramps.

It goes on and on and it can literally be life threatening.  Make sure you play it safe. Be careful in temperatures like this. This is not the time to go outside and exercise.  It's not the time to prove a point; stay indoors.

If Roy Halladay is having problems out there you can have problems as well.
