Summary
# Editorial Summary: Air Speed to Increase Rate of Cool Out for Horses After Intense Exercise Cooling protocols following strenuous exercise remain fundamental to equine management, yet optimising recovery time has received limited investigation. McGill, Coleman and Hayes examined whether directed air flow could enhance conventional cooling procedures (walking and water drenching) in seven Thoroughbreds exercised over 1–1.5 miles, comparing outcomes across three conditions: no fan, lateral fan placement, and posterior fan placement. Whilst the multivariate analysis yielded no statistically significant differences between treatments, both rectal temperature and heart rate demonstrated clinically meaningful trends towards faster baseline recovery when fans were deployed (P = 0.10 and P = 0.11 respectively). The findings suggest that incorporating forced air circulation into post-exercise routines may modestly accelerate physiological normalisation, potentially reducing the period during which horses remain thermally stressed, though larger sample sizes would strengthen these preliminary observations. For practitioners, adding fans to existing cool-out protocols represents a low-cost, low-risk intervention worthy of further investigation, particularly in hot climates or high-performance settings where rapid recovery is operationally important.

Practical Takeaways
- •Using fans during cool-out may marginally accelerate the return of core temperature and heart rate to baseline, though the effect is modest in this study
- •Fan placement does not appear to substantially impact cooling efficiency, giving flexibility in practical application
- •Traditional cooling methods (walking + drenching with scraping) remain the primary cooling strategy; fans may provide minor supplementary benefit
Key Findings
- •No statistically significant differences in cool-out rate were found between fan treatments (P > 0.05)
- •Rectal temperature showed a trend toward faster return to baseline with fan use (P = 0.10)
- •Heart rate showed a trend toward faster return to baseline with fan use (P = 0.11)
- •Fan direction (lateral vs. posterior) did not significantly alter cooling outcomes in this small sample
