Recently I posted about ways to reward yourself for a workout well done, and one of those (and my favorite) is taking a sauna. I don't need to tell you about how great it feels. What I do need to tell you is you to hold off on jumping into the sauna, hot tub or steam room immediately after finishing your workout.
The heat from outdoors combined with the heat of the sauna can have a detrimental effect on your body. After working out, you already have elevated temperatures and your blood vessels are dilated. The heat needs to dissipate in order to bring your heart rate back to your resting zone and to bring blood back to your vital organs - cool downs are not just about finding time to stretch. So instead of rushing into more heat that can cause lightheadedness, dizziness, fatigue, nausea or worse, heat exhaustion, heat stroke and heart attacks, try a cool shower instead. Basically you need to allow your heart rate to return to resting levels before treating yourself to some relaxing heat at the end of your workout.
