Summary

This study looked at whether taking a 10-minute cold water bath (around 55°F) after training helps NCAA Division I athletes recover and perform better. 75 volleyball, football, and cross country athletes wore a WHOOP device to track sleep, heart rate, and other recovery signs. They also did jump and strength tests. The goal was to see if cold water immersion improves recovery and performance compared to no treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
cold water immersion
What this could lead to
If it works, this could provide a simple, drug-free way for athletes to recover faster and improve performance after training.
What could go wrong
This is a small, completed study with no phase designation, so results may not apply to all athletes or sports. The benefits may be minimal or not significant.
