A wide range of stressors are linked to the development of hypertension. These include chronic life stressors such as persistent job strain, marital conflict, natural disasters, and exposure to high levels of traffic noise at home. Perceived discrimination has also been identified as a significant factor, particularly among African Americans. Furthermore, acute stress induced in laboratory settings—through tasks like timed mental arithmetic, the cold pressor test (immersing a hand in ice water), mirror tracing, and public speaking—has been demonstrated to cause temporary elevations in blood pressure.
