Study of the Effect of Elastic Compression (French Class III) on Water Balance Change in Healthy Subjects

Study of the Effect of Class III Elastic Venous Compression Focused on 33 mmHg on Water Balance Change in Healthy Subjects. Exploratory, Randomized, Open-label, Controlled and Crossover Study

The main objective of this study is to compare precisely, under standardized test conditions, water balance changes in healthy subjects with or without the daytime use of compression stocking.
