My case for immediate cryotherapy:
Does Cryotherapy Hasten Return to Participation? A Systematic Review
Tricia J. Hubbard,corresponding author Stephanie L. Aronson, and Craig R. Denegar
*Based upon acute injuries, but the same would go for microinjuries.
EFFECTS OF CRYOTHERAPY ON MUSCULAR POWER
Rogers, J T.1; Albrechtsen, S J.1

*Found that cryotherapy increased high intensity short duration exercise (Wingate protocol).
The Effect of Cryotherapy on Eccentric Plantar Flexion Peak Torque and Endurance
*Found that cryotherapy increased endurance in repeated cycles. This is a study of repeated bouts in one session, though.

First of all, it will expedite fluid loss--a trend you want to stop and reverse as soon as possible. Dehydration is NEVER desirable in an athlete.
Effects of a postexercise sauna bath on ECG pattern and other physiologic variables.
Paolone AM, Lanigan WT, Lewis RR, Goldstein MJ.
*Found that immediate sauna can alter physiologic values, perhaps dangerously.
Children in sauna: electrocardiographic abnormalities.
Jokinen E, Valimaki I.
*Increased sympathetic activity during a time where I'd like to be decreasing it from the workout prior.
More later, if necessary. Gotta get back to work.
