Brief Summary
The purpose of this study is to determine whether inversions (specific yoga postures in which the heart is higher than the head) and other dynamic and static yoga postures affect heart rate variability, oxygen uptake, blood pressure, blood parameters and other objective measures of health, and a variety of subjective and objective measures of health in female and male individuals in Sweden.

Outcome Measures
Primary Outcomes (2)
Change in heart rate variability
We will measure the change in this variable over time. The first measurement will be at baseline and the second at the end of the 8-week intervention (main measurement). If and only if there are effects after the 8-week intervention, we will follow up the participants at various intervals to determine how long the effects are sustained. These follow-ups will be conducted 3 months, 6 months, and 12 months after the end of the intervention.

Study Arms (2)
Yoga group
EXPERIMENTALParticipants in this group will take part in six to eight weeks of yoga classes. The classes will be held once a week and each class will be approximately one hour long. The classes will consist of yoga inversions, sun salutations and other yoga postures with deep breathing.
Control group
NO INTERVENTIONMatched control
Interventions
6 weeks of yoga postures, once a week for 60 minutes in a group session with a yoga teacher.
