Blood pressure modulates a person's tendency to worry and can be associated with a "tranquilizing" effect when elevated. This is indicated in a new study that reflects how we can implicitly learn to increase our blood pressure as a way of alleviating tension and emotional unease. A new study points out that our predisposition to worry is linked with blood pressure and baroreceptor reflex sensitivity, fundamental in the stabilization of blood pressure and activated by receptors located in the aortic and carotid arteries.
