Post‐prandial hyperglycemia is a function of glucose absorption, insulin secretion, and insulin sensitivity. A variety of pharmacological interventions improve these parameters. Relaxation breathing is an easily replicated respiratory exercise that may also improve glycemic and insulinemic responsive. In this study healthy subjects were randomized to control breathing (CB; n=13) or relaxation breathing (RB; n=13) groups that received an oral glucose tolerance test (OGTT; 75g/240mL) following a 30 min acclimation period of CB or RB repeated every 10 minutes. Blood glucose was measured at 0 min (pre‐OGTT), and 30, 60, and 90 min post‐OGTT with continued RB (CB: 97±9, 173±30, 159±40 and 137±37; RB: 94±7, 137±29, 166±35, and 130±25mg/dL). RB blood glucose was significantly lower at 30 min (p= 0.004). Plasma insulin for CB and RB at 0, 30, 60 and 90 min was not significantly different, however the insulin AUC for CB and RB was 3155±1272 and 5130±3022 μIU·min/mL (p= 0.098). While pharmaceutical interventions may improve insulin secretion and glycemic control, relaxation breathing could provide a non‐pharmacological approach to improving these parameters in type 2 diabetics. Furthermore, investigators may need to control for respiratory pattern when calculating food glycemic index.
