Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* African American
* Adults ages 18-60 years

Exclusion Criteria

* pregnancy or within 60 days postpartum
* having taken blood pressure (including diuretics beta-blockers, ACE inhibitors, angiotensin receptor blockers, and calcium channel blockers) or statin medications within the past 3 months (statins have been demonstrated to reduce oxidative stress which could impact flow-mediated dilation);
* infection (viral or other) within the past 4 weeks;
* having adrenal or endocrine tumors (these could impact BP);
* renal disease defined as a glomerular filtration rate (GFR) of less than 60 (creatinine will be tested at initial screening and GFR will be calculated);
* prior myocardial infarction; vii) known coronary heart disease;
* personal history of stroke;
* heart failure;
* cardiac arrhythmias;
* chronic obstructive pulmonary disease;
* recent chest pain or dyspnea;
* orthopedic limitations that preclude the execution of yoga postures;
* current insulin dependence;
* currently taking steroid medications;
* currently undergoing chemotherapy or radiation;
* having practiced yoga or yogic breathing techniques at least once weekly consistently within the past 3 months;
