Cooling Modalities for Elderly During Heat Waves

This study is looking at how different cooling methods can help older adults (65 years and older) cope with heat waves. Researchers want to see if using a water spray, a fan, or both, can reduce stress on the heart during hot and humid or very hot and dry conditions. You would be exposed to simulated heat waves and receive one of these cooling methods, or no cooling at all. The main goal is to measure changes in your body temperature and how well your heart is working. To join, you must be 65 or older and generally healthy, without significant heart disease or other chronic medical conditions. The study plans to enroll 100 participants, but its current status is unclear.

Study design
This interventional study plans to enroll 100 participants. It compares four different approaches: water spray, fan, both water spray and fan, and no cooling (control).
What's involved
You would be exposed to simulated heat wave conditions for 3 hours. Measurements of your body temperature and heart function will be taken before, during, and after this exposure.
Compensation
Not stated in the trial record.
Follow-up
Your body temperature and heart function will be measured within 60 minutes before the heat wave exposure, around 90 minutes into the exposure, and at the end of the 3-hour heat wave exposure.

Eligibility criteria

Inclusion

65 years of age or older
Free of any significant underlying medical problems based upon a detailed medical history and physical exam

Exclusion

Known heart disease
Other chronic medical conditions requiring regular medical therapy including cancer, diabetes, uncontrolled hypertension, and uncontrolled hypercholesterolemia etc;
Abnormality detected on routine screening suggestive of provokable ischemia or previously undetected cardiac disease or resting left bundle branch block on screening electrocardiogram.

What this trial measures

  • Change in core body temperatureBody core temperature will be obtained within 60 min before the heat wave exposure after the 3 hour heat wave exposure.

    Change in core body temperature will be measured either from a temperature sensor pill or from a rectal thermometer

  • Change in left ventricular functionWithin 60 minutes before each simulated heat wave exposure, around minute 90 of the heat wave exposure, and at the end of the 3 hour heat wave exposure

    Measures of left ventricular function, such as ventricular wall motion and ventricular filling, will be obtained from echocardiography images.
