An interventional study of Whole-body Passive Heat Therapy (HT) and Thermoneutral Control (CON) in Renal Insufficiency, Chronic, sponsored by Virginia Commonwealth University. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-10-10.

The objective of this proposal is to investigate the acute effects of whole-body passive heat therapy using far-infrared technology on vascular function, exercise capacity, and renal function in CKD patients. The central hypothesis is that an acute bout of whole-body passive heat therapy will be well-tolerated and lead to acute improvements in large blood vessel (macrovascular) function, small blood vessel (microvascular) function, and exercise capacity without significantly altering markers of acute kidney injury.

Exclusion Criteria for participants with CKD:
Heat therapy will be administered using an infrared sauna. The intervention duration will last 25 minutes at a temperature of 60°C.
Procedure: Whole-body Passive Heat Therapy (HT) · Procedure: Thermoneutral Control (CON)
The whole-body passive heat therapy (HT) intervention will consist of an acute bout of infrared sauna for 25 minutes at 60°C. Participants will lie supine on a memory foam pad.
Participants will remain in a room temperature environment (22°C) underneath the infrared domes for 25 minutes.
