Summary

This trial tests whether taking a 15-minute hot bath after each exercise session improves recovery in people who recently had a heart attack. Half of the 30 participants will do standard exercise rehab plus hot water immersion, while the other half does exercise alone. The study measures changes in inflammation, metabolism, heart function, and well-being after 8 weeks to see if the hot baths add extra benefit.

What this could mean

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

Active substance: Hot water immersion (bathing in hot water) after exercise sessions
What this could lead to: If effective, adding hot baths to standard rehab could offer a simple, low-cost way to lower inflammation and improve heart function after a heart attack.
What could go wrong: This is a small, early-stage trial with only 30 participants, so results may not apply broadly. Hot baths may not provide added benefit over exercise alone and carry risks like overheating or dizziness.
