Effect of Hot Water Immersion on Heart Rate Variability and Glucose

Not Applicable

Completed

• Conditions: HRV; Glucose Tolerance
• Interventions: Procedure: Feet heating; Procedure: Calf heating

• Registration Number: NCT06193291
• Lead Sponsor: San Diego State University

Brief Summary

Heat therapy has been shown to reduce risk of various diseases, including heart disease, alzheimers, and pneumonia, as well as all-cause mortality . A previous study found heating a single hand lowers postprandial blood glucose levels with a magnitude similar to certain exercise interventions such as 40 minutes of slow walking We propose that heating both feet and heating both legs up to the calves will result in similar glucose reductions in a dose response manner.Overview To determine the effect of heating both feet to the ankles and heating both legs to the calves on postprandial blood glucose
