简要总结

A study to explore whether different temperatures of warm water footbaths have different effects on the cardiovascular system, the autonomic nervous system and the general well-being of healthy women.

详细描述

This is a blinded, four-arm randomized controlled trial with crossover design to explore the effects of warm water footbaths with different water temperatures on cardiovascular stress, reaction of the autonomic nervous system and a feeling of comfort and warmth in healthy female volunteers. Cardiovascular and ANS measurements are performed continuously throughout the interventions and the participants rate their feelings of warmth, general well-being and the footbath-related comfort with questionnaires.
