Running Hot and Cold before your Marathon. The power of a contrast bath.

I get asked a lot by athletes 'What can I do to recover faster' or 'What can I do before a race if I am sore'. I almost always bring up contrasts baths. And that almost always that leads them to say 'What is that?'

If I think back to the time of where I first knew of contrast baths, it really brings up images of 80's sports movies where athletes are dunked in big steel tubs of ice, or institutional baths. They are ugly steel contraptions set awkwardly in corners of locker rooms. In today's utterly perfect, slick, performance world I can't remember seeing them anywhere. Instead, we eat a vitamin-filled gummy, or wear cool colored tape for our recoveries; however, the contrast bath should not be over looked. It is a huge tool in recovery, and if you are running with an injury you should not be running with, it might be a game changer.

A contrast bath is a simple rehab tool anyone can use that helps decrease inflammation, decrease pain, decrease swelling, and potentially increase mobility. The bather, moves from a tub of warm water, to a tub of cold water and back for a cycle of 30 minutes. The back and fourth temperature changes from warm to cold, cause your circulatory system to repeatedly vaso-constrict and vaso-dilate. That "squeeze - release" action moves the fluid through your body at an expedited rate....as IF you were exercising but without the actual risk of exercising. 

We all know our blood moves through our body by the hearts pumping mechanism, but it does not move the blood by its power alone. Your muscle movement provides a very strong secondary pump that facilitates fluid movement throughout your body. For example, some of you might have noticed that your legs swell up a bit from lack of  movement when you are on an airplane. 

Plunging your whole body from hot to cold, or part of your body, can mimic the normal muscle movement, and be a very effective way of moving things along, especially if you are too close to race time to risk a massage, or cannot access treatment. In most cities there are bathhouses that have alternating cold hot dips that athletes can utilize for full-body plunges. You can also put one together at home with the use of buckets and thermometers. The bucket version is best for ankles and arms, or you can do a hot/cold compress for harder to reach areas. 

Before we get to the nitty-gritty of the recipe, I should like to add that it‘s very important to check with your doctor if you have any questions about if this is right for you. Anyone with circulatory problems, Reynaud’s, decreased feelings in their limbs or compromised skin should not be doing a contrast bath because it puts you at risk.

Here is the recipe for your contrast bath (if you are at home you will need a thermometer)

30 minute cycle repeating hot/cold and always ending on the hot

3-4 min hot water (100F)

1 min cold water (60F)
