“Physical activity was roughly twice as effective in lowering cardiovascular disease risk among those with depression. Moreover, reductions in stress-related brain signaling partially accounted for physical activity’s cardiovascular benefit.Īs an extension of this finding, the researchers found in a cohort of 50,359 participants that the cardiovascular benefit of exercise was substantially greater among participants who would be expected to have higher stress-related brain activity, such as those with pre-existing depression. Analyses accounted for other lifestyle variables and risk factors for coronary disease. Notably, reductions in stress-associated brain activity were driven by gains in function in the prefrontal cortex, a part of the brain involved in executive function (i.e., decision-making, impulse control) and is known to restrain stress centers of the brain. Individuals with higher levels of physical activity also tended to have lower stress-related brain activity. Participants who met physical activity recommendations had a 23 percent lower risk of developing cardiovascular disease compared with those not meeting these recommendations. Over a median follow-up of 10 years, 12.9 percent of participants developed cardiovascular disease. To assess the mechanisms underlying the psychological and cardiovascular disease benefits of physical activity, Ahmed Tawakol, an investigator and cardiologist in the Cardiovascular Imaging Research Center at Massachusetts General Hospital, and his colleagues analyzed medical records and other information of 50,359 participants from the Mass General Brigham Biobank who completed a physical activity survey.Ī subset of 774 participants also underwent brain imaging tests and measurements of stress-related brain activity. In the study, which was led by investigators at Massachusetts General Hospital and published in the Journal of the American College of Cardiology, people with stress-related conditions such as depression experienced the most cardiovascular benefits from physical activity.

Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. You may also benefit from cognitive behavior therapy, a form of talk therapy designed to change the way you think about a problem in order to change your emotional reaction to it and the way you behave toward it.

This involves playing background noise, such as soft music or “white noise,” to distract you from the tinnitus or change your brain’s sensitivity to the pitch of the tinnitus. If the blood vessel can’t be treated, you may benefit from sound therapy. A flexible mesh tube, called a stent, is sometimes placed in a blocked artery to open it up and improve blood flow. If the cause relates to a specific problem in an artery or vein, surgery or a catheter procedure may be needed to treat the condition. High blood pressure and vein and artery conditions can usually be treated with a combination of medications and lifestyle changes, including: Pulsatile tinnitus is often treated by addressing the underlying cause. Your ears may pick up on this turbulent or irregular circulation, causing pulsatile tinnitus.Ī tumor that presses against a vein can also cause pulsatile tinnitus.Ī problem with the tiny blood vessels that help connect your arteries to your veins, or capillaries, can cause pulsatile tinnitus. Narrowed neck arteries ( carotid arteries) or veins (jugular veins) may also cause a change in blood flow to and from the head. Read more: Is it possible to reverse atherosclerosis? » If this is the cause, you may hear a rhythmic noise in one of your ears. More forceful blood flow in arteries in or around the ears is easier for your ears to detect.īlockage in your arteries caused by a buildup of cholesterol, fats, and waste materials can cause blood flow to be turbulent.

When your blood pressure rises, the force of blood against the inner walls of your arteries increases. There are many possible causes of pulsatile tinnitus, but they all stem from circulation issues.
