Summary

In this study, the effect of dehydration by sauna exposure on the intestinal permeability in 20 healthy subjects is investigated. Participants attend three visits: 1) Sauna visit (to achieve 3% dehydration), 2) Positive control visit (intake of indomethacin which is known to increase intestinal permeability), 3) Negative control visit. At all visits, saliva samples, blood samples, faecal samples, saliva samples are collected and the multi-sugar permeability test is performed. In this test, participants drink a sugar solution and then urine collect urine for 5 and 24 h. The ratio of the sugars detected in the urine by liquid chromatography/mass spectometry is a reflection of the intestinal permeability. Saliva samples are collected for assessment of cortisol, a stress marker. Blood and faecal samples are collected for assessment of markers of intestinal barrier function and inflammation.

Conditions

• Dehydration
• Indomethacin

Interventions

Type	Name	Description
OTHER	Dehydration by sauna exposure	Participants repeatedly undergo sauna exposures until they loose 3% of their body weight.
DRUG	Indomethacin	Participants take indomethacin in tablet form the evening before and the morning of the visit to induce intestinal permeability
