A doctor's presence during a blood pressure reading triggers a "fight or flight" response that can affect the results, say researchers who studied the effect by measuring nerve activity.
Two long used types of blood pressure drugs are equally effective, but the less popular one seems to have fewer side effects, according to a large "real-world" study.
A quick daily "workout" for the breathing muscles may help people lower their blood pressure to a similar degree as exercise or even medication, a small study suggests.
