Effects of Oral Ingestion of Drinking Water Using a Tumbler That Emits Far Infrared Rays on Metabolic Profile

Effects of Oral Ingestion of Drinking Water Using a Tumbler That Emits Far Infrared Rays at Room Temperature on Metabolic Profile in Adults: a RCT

The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of oral ingestion of drinking water using a tumbler that emits far infrared rays at room temperature on metabolic profile in adults for 8 weeks.

The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of oral ingestion of drinking water using a tumbler that emits far infrared rays at room temperature on metabolic profile in adults for 8 weeks; the safety of the compound are also evaluate. The Investigators examine lipid profile, glucose, liver and renal function at baseline, as well as after 4, 8 weeks of intervention. Thirty adults were administered either 1.8 L of drinking water using a tumbler that emits far infrared rays at room temperature or drinking water using a sham-tumbler each day for 12 weeks.
