David Sheridan, M.D., demonstrates the smart watch that measures a person's heart rate. Sheridan’s recent study found an inverse relationship between HRV and suicidality. As suicidality levels increase, the parasympathetic nervous system’s signals decrease, reducing one’s ability to calm oneself down. (OHSU/Christine Torres Hicks)
