Protective Cooling Measures for Heat Stress in the Elderly

Q: Am I able to join the experiment?

<p>This clinical trial requires 60 seniors with <a href="https://www.withpower.com/clinical-trials/hypertension">hypertension</a>, ranging in age from sixty to eighty-five. Notably, individuals must also satisfy the following additional criteria: BMI lower than 35 kg/m2; for individuals identified with <a href="https://www.withpower.com/clinical-trials/type-2-diabetes">type 2 diabetes</a> - at least one year has elapsed since diagnosis and their hemoglobin A1c levels are between 6.0-10.5%; finally, those diagnosed with <a href="https://www.withpower.com/clinical-trials/high-blood-pressure">high blood pressure</a> need a minimum of twelve months to have passed since their initial diagnoses or an average resting systolic reading higher than 140 mmHg and diastolic greater than 90mmHg</p>

Study Summary

This trial will assess whether shorter but more frequent air-conditioning exposure provides more effective cooling than current recommendations in older adults with or without common chronic health conditions.

Who is the study for?

This trial is for adults aged 60-85 with high blood pressure or Type 2 diabetes, but not severe related complications. They should have a BMI under 35 and can't be smokers or heat-adapted from saunas or travel to hot climates.Check my eligibility

What is being tested?

The study tests cooling strategies against summer heat for the elderly. It compares no cooling, recommended long-duration cooling, and shorter more frequent cooling sessions during simulated extreme heat conditions.See study design

What are the potential side effects?

Since this trial involves non-invasive interventions like exposure to air conditioning as a form of cooling, there are minimal expected side effects compared to medicinal trials.

Answered by AI

Is there an age restriction for participating in this experiment?

"This trial is exclusively for seniors aged between 60 and 85. There are currently 85 studies that accommodate participants younger than 18, and 1011 trials available to individuals over 65."

Answered by AI

What is the purpose of this experiment?

"This clinical trial will assess the Core temperature (AUC) of participants over 8 hours as its main outcome. Secondary outcomes include RMSSD, Arterial blood pressure, and Mean skin temperature - all assessed using 3-lead ECG, Systolic and diastolic pressures in triplicate readings respectively, and a weighted average of body temperature from 8 key regions."
