Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will receive all interventions in a random order.
All interventions occur only once per participant, with a week between interventions. The interventions will take place after an initial blood pressure reading, and will be followed by another blood pressure reading after the intervention. Each intervention will be administered by the clinician GP, who will also monitor adherence.
1) Mantra chant: while sitting, taking deep breaths, on the third exhale humming the sound OM, 30 seconds in total
2) Chair-based yoga stretch: Chair Warrior and Spinal Twist, 30 seconds in total
3) Breathing exercise: Double inhale & extended exhale technique, 30 seconds in total

Summary
Brief summary
White coat hypertension is when a person's blood pressure readings are too high in a medical setting, like a doctor's office, but are normal elsewhere, like in your home. This condition has been considered not malignant in the past, but recent research has shown that it should be a cause for concern due to poor long-term health outcomes which may require further monitoring or treatment.
Mindfulness interventions, like specific breathing techniques, have been shown to lower blood pressure in adults with essential hypertension. The techniques, however, have not been tested for white coat hypertension, and in addition, have only been found to work if used for weeks.
Therefore, this study aims to explore whether 30-second mindfulness interventions like a mantra chant, a yoga pose, or a breathing exercise can lower blood pressure readings in Australian adults with white coat hypertension.
