This study looks at whether measuring heart rate variability for different lengths of time (1, 5, 10, or 20 minutes) gives the same results, and how those results relate to blood pressure. About 40 healthy adults will wear a chest strap for one visit. The goal is to help research…

This study will test how stimulating the ear with mild electrical pulses at different frequencies affects heart rate, breathing, and blood pressure in 36 healthy adults. Each person will try five different stimulation settings (including a fake one) in separate sessions. The goal…

This study will test whether stimulating the vagus nerve through the ear for 5, 10, or 15 minutes changes heart rate, blood pressure, and other body signals in healthy adults. Forty-four participants will receive either real or sham stimulation in random order. The goal is to see…
