Brief Summary

The purpose of this study is to determine the safety on sauna followed by cold water bath, a common practice in many countries, 30 healthy subjects aged 40 years and older will be at the Montreal Heart Institute Prevention and Cardiac Rehabilitation centre.

Conditions

Blood Pressure; Arrhythmias

Keywords

Sauna; Cold water bath

Outcome Measures

Primary Outcomes (1)

• Blood pressure

  Difference between baseline and 11 minutes of intervention.

Secondary Outcomes (2)

• Arrhytmias

  Number of arrhytmias during all 25 minutes of the intervention.

• Blood pressure

  Measured at 10 minutes after the end of the intervention (recovery period).

Study Arms (1)

Sauna + Cold Water Bath

EXPERIMENTAL

Subjects will first spend 10 minutes in a dry sauna at 85 degrees celtius. Immediately after , subjects will be immersed in a cold water bath (ICool , Australia) at a temperature of 5 degrees celtius for approximately one minute. Blood pressure , ecg , gaz exchange and thoracic impedance will be measured during sauna and cold water bath.

Other: Sauna and cold water bath
