Optimizing Cold Water Immersion for Exercise-Induced Hyperthermia

“…One additional study was identified through another source. The search was completed in December 2014, identifying 19 eligible studies for the meta-analysis (3,10,(15)(16)(17)19,25,29,33,35,44,(46)(47)(48)53,58,61,62,65). A flow diagram illustrating the literature search process is presented in Figure 1.…”

Acute Whole-Body Cooling for Exercise-Induced Hyperthermia: A Systematic Review

“…All studies that met the inclusion criteria, however, met the criterion score of 4/10. [18][19][20][21][22][23][24] To determine if recommendations for certain modalities were warranted, we identified 3 categories of cooling based on efficiency. Category A required approximately 20 minutes of cooling for an EHS patient with a maximum core body temperature of 42.26C (1086F) to be cooled to 38.896C (1026F).…”

“…Some authors included other outcome variables, but because our original research question focused specifically on cooling efficiency after exercise-induced hyperthermia, we included only data related to these criteria in the current review. 18 Clements et al 21 Kielblock et al 19 Proulx et al 22 Scott et al 23 Wyndham et al 20 Clapp et al 24 Eligibility criteria were specified (no points awarded).…”

“…18,[21][22][23] When reported, time to treatment ranged from 1.5 to 8 minutes. An author of another study 24 was contacted and stated that the average time to treatment was approximately 5 minutes. The other 2 studies 19,20 were published more than 20 years before our search, and we were not able to contact those authors.…”

Heat illness

“…The main disadvantages are patient and attendant discomfort, induced shivering, difficulty with patient monitoring equipment and resuscitation efforts (making safe defibrillation almost impossible) (5,8,17,18,33,36). An effective alternative to full body immersion is to place only the patient's hands and feet in cold water (65).…”
