Read our Heart Failure research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how extreme heat affects people with heart failure and whether simple cooling methods—like wetting your skin or wearing a wet shirt—can reduce the stress on your heart during heat waves. This study will expose participants to simulated hot conditions while testing different cooling approaches to see which ones work best at keeping your body temperature down and protecting your heart.
Heat waves can be dangerous for people with heart failure because high temperatures force the heart to work harder. This study aims to find simple, affordable ways to help protect people with heart failure during dangerously hot weather.

You will visit a research facility where you'll be exposed to simulated hot conditions three separate times in random order: once with no cooling, once with just your skin being wetted, and once wearing a water-saturated shirt. During each session, researchers will monitor your body temperature, heart rate, and how your heart is functioning using heart tests and imaging. The study will measure how well each cooling method protects your heart during heat stress.
