Heat as a stroke therapy

I guess I've been missing this the past 7 years. In Tampa in 100 degree weather is great. Extra sensation therapy by feeling all that sweat on your skin, including it running down your back and armpits. You can practice new movements, wiping sweat from your brow with your affected hand.  I'm surprised my therapists didn't know about this stroke protocol.
You might want to be concerned about this though;

California climate linked to ER visits The risk of heading to the ER for certain conditions, such as heart disease, diabetes, stroke, kidney disease and low blood pressure rises slightly as temperature and humidity increase, according to a new study. 

But what the hell do you think your doctor is for except to answer conundrums like this. They went to medical school, you didn't. So ask whether the better sensation therapy offsets the stroke risk.
